View Full Version : Weird, faint screen lines over everything on G75WV-BBK5

I just got this new G75WV-BBK5 less than a month ago, and I'm having an issue with the screen

I noticed these small lines on the default desktop wallpaper, but I assumed they were normal (from compression of the image or something). Recently, however, I notices lines on my screen while playing a game, and then started looking for them. They're mainly visible on dark colors. There are horizontal lines over the entire screen, about 2 pixels in height and 2 pixels apart. It creates this effect where the color behind them is slightly darker or lighter than the rest of it. Here's an image to show what I'm talking about: http://i.imgur.com/nml86.png

I plugged up the notebook to my 42'' 1080p 120hz tv, and it didn't have this problem. I tried changing my refresh rate to 40hz (the only other option apart from 60) and the issue was still there. The lines just flickered more.

Is this normal? Is this model just like this? Could someone with this model (or a similar model) take a look at a picture like this: http://i.imgur.com/7kTcL.png ? That color causes the issue pretty obviously. Look at the screen from a downward angle (from higher than the screen) and let me know if you see the same thing I'm seeing. If this isn't normal, the only thing I can think of is that my gpu is shot or my monitor is screwed up. If it is normal, then why is it like this? o_O

In a last effort, I'm downloading the new nvidia verde driver to see if maybe it has to do with a refresh rate issue, but I kinda doubt it. To be honest, even if there is no fix, I'd find comfort in knowing that it's normal for this model. If nothing else, I might go to best buy to look at the floor model and see if it has the same issue.

Thanks in advance


EDIT:

1.) The lines are solid, not really flickering
2.) They are about 2 pixels thick, 2 pixels apart across the entire screen, horizontal
3.) They make the color either slightly lighter or slightly darker, causing the effect seen here: http://i.imgur.com/nml86.png
4.) It can be seen with the brightness of the screen turned all the way up, and viewed from a slightly higher-than-straight-on angle.
5.) The lines can only be seen on dark colors (not black), like this (http://i.imgur.com/7kTcL.png) or this (http://postimage.org/image/a5thle5mn/full/)
6.) The lines are entirely gone in 16-bit color modes, and pretty visible with 32-bit color.
7.) I've updated to the latest Nvidia beta verde driver, and it hasn't fixed the problem.
8.) I've changed the screen refresh rate to everything between 60 and 80 hz, and it hasn't fixed the problem. At lower frequencies like 30 or 40 hz, the lines appear to flicker (although this might just be because of the lower rate messing with my eyes)

I honestly think this could be a widespread issue with this laptop that not many people noticed. I've used this thing for 3 weeks and just noticed it yesterday. It can only be seen (as far as I can tell) from a semi-high angle, on dark colors, with full screen brightness, or at least this is the best way to spot the problem.

1) The latest NVIDIA 304.48 BETA driver has resolved the "flickering horizontal lines" issue for several users. The more recent driver versions may also help with this. Issue.

2) Creating an NVIDIA Custom Resolution with a Refresh Rate of 67 Hz or 75 Hz in the NVIDIA Control Panel as discussed by @ny2lond has resolved this issue for others. See http://rog.asus.com/forum/showthread.php?5536-Asus-G74-screen-flicker-(dark-backgrounds-and-low-brightness)&p=108570&viewfull=1#post108570 for details.

Well, I tried making that custom resolution before updating the driver, and the issue was still there. Then, I upgraded to the latest Nvidia beta driver (304.79). It didn't fix the problem either. Then with the new driver, I attempted to try 67 and 75 hz refresh rates, and still nothing.

I guess I should say, the lines don't really appear to flicker, per se. They seem pretty constant. Also, I just realized, they're gone entirely when the resolution is set with 16-bit color quality. Any more ideas? :/

Thanks for the help

Ok, well, I downgraded to the 304.48 driver, and the problem is still there. Changing the refresh rates doesn't remove the lines... I can tell that at certain times, they might be changing position vertically when the refresh rate is changed, but they're always there. Raising the refresh rate is just making them more 'solid'. I've tested everything between 60 and 80 hz, and still nothing. I even tested 30 hz just to see what it would do, and it just made the lines flicker a lot. Please, does anyone have any more ideas? This is driving me nuts.

Are you sure its not just the matte finished screen? Because I switched from glossy to this and realized it looks grainy if you look closely , and thats normal for a matte finish screen. It just takes a while to get used to. Dark backgrounds well show less grain, and sunlight or light because its anti glare.

No, it's not that.

1.) They're pretty obviously distinguishable lines, if you're looking for them. Did you see that image I first posted? That's what I'm talking about
2.) It sounds like what they're talking about in that thread the other guy linked to (the problem most of them said the driver fixed)
3.) The problem goes away entirely at 16-bit color, so its not the screen finish

If you have this same laptop, could you take a look at this for me? http://postimage.org/image/a5thle5mn/full/
Take a look at your screen, full brightness, from a slightly upward angle, and see if you can see lines on the page. There aren't any lines on this image, and if you see the faint lines, you have the problem too

Hm. Do you see any lines in this image? http://s11.postimage.org/ppgk6buhf/black.jpg

How about this image? http://s10.postimage.org/qoikclkzt/black.png

Is your example a photo of something black?

In 16bit there are far less colors that 32, thus the computer will give variations as same color.

I can see your horizontal lines. They are gone on my XPS (there I can see 2 vertical lines that are not on G75). I'll look into it. This is not flickr.

Nope, no black lines at all on either of those images. My example photo was the dark blue spots on the default wallpaper with this laptop (http://i.imgur.com/LT9js.jpg). It only occurs on dark colors. I know that 16 bit shows far less colors, but I would expect to see these lines on any shade of dark brown or dark blue or anything else like that. In 16 bit there are NO lines whatsoever, and they're pretty noticeable in 32 bit when I look for them. And ideas? I know it must have something to do with the driver and/or refresh rate, but I just can't seem to find the winning combination for this model...

Nope, again, I hooked it up to my tv and it didn't have the issue. Also, I can move an image with these lines on it around on my screen, and definitely can tell its not part of the image itself. It's gotta be an issue with the refresh rate or monitor, not the gpu with artifacts.. It sounds exactly like the problems those other people were having in that other thread linked above, but their fix didn't resolve it for me...

You're right, I missed the bit where you said you connected it to the TV.

Normally if there was an issue with the LCD panel I'd expect the lines to be either completely horizontal or completely vertical, but given the troubleshooting done, I'd say it sounds like the possibility of a bad LCD panel is pretty close to the top of the list. It's your call if you want to go the RMA route, but were I still working as a hardware tech I'd be pretty satisfied that it's not likely a software issue.

It's not Windows, the GPU, the drivers or ICC profile. It's no flickr.

I have been playing around with Linux a bit and the problem is here.

I don't think there is a solution. The Chi Mei panel could be this bad. I knew about the grain problem and that was fine. This? I don't think I can tweak my way out of this. Hm ...

This kinda ruins a lot for me as I make some shots from time to time. But not lately so it just passed by.

A strange thing, on Linux I have refresh at 61hz (this is the default setting) and there is no flickr. I shall try this 61Hz in Windows to see if that just +1 is a fix for the flickr. The flickr and the lines are different problems.

Also, getting Linux to work is such a pain. Took me a while.

We need to see how many people have this problem.

Argh... I really don't want to have to send this thing in for repairs, especially within the month that I brought it home. The lines are so faint, and show up on very dark colors... I'm wondering if this is just an issue with all BBK5's that nobody has really noticed yet. Can I get one owner of a G75VW-BBK5 to please look at these: http://i.imgur.com/7kTcL.png http://postimage.org/image/a5thle5mn/full/ and tell me if you see the lines?

Also, not sure if i misunderstood you or whatever but yeah, all of the lines are horizontal. And its not just spotty or anything, its the entire screen with lines, about 2 pixels high and 2 pixels apart.

Ok well I have no issue with flickering (as you, and some of the people in that other post mentioned). I just have the solid lines.

I'm gonna post here a list of what causes it, and how it can be seen, and if I can I'll edit the first post with it as well.

1.) The lines are solid, not really flickering
2.) They are about 2 pixels thick, 2 pixels apart across the entire screen, horizontal
3.) They make the color either slightly lighter or slightly darker, causing the effect seen here: http://i.imgur.com/nml86.png
4.) It can be seen with the brightness of the screen turned all the way up, and viewed from a slightly higher-than-straight-on angle.

I have the exact same problem. And I actually had and RMA done, and they replaced my LCD (took 2 weeks altogether), and to my disappointment, the problem still persisted :( I even included some photos highlighting this problem for the technicians to see, yet I was told that they had no idea what the problem was (had to instruct them to read the included RMA slip for instructions).
Anyway, here are the photos I included. Let me know if you see the lines within the marked circles: 10781107821078310784

And the problem disappears completely when I hook it up to a TV or an external monitor. It's just the actual LCD on the laptop that has this problem.I have the RS72 model instead of the BBK5 btw. I called support again and made another RMA since the problem hasn't been resolved. I should mention that I looked at 2 display models today at 2 different stores, and they both had the same issue! So before I send it back for support, I wanna make sure that they'll be able to fix the issue, instead of making me wait another couple of weeks for nothing.

The issue has become so distracting now that I can't play games on it without cringing. It's one of those things that once you see it, you can never unsee it!

PS: Hit fn+C until you get to Vivid Mode. For me, it makes the issue almost disappear completely, but of course, it screws up the colours, so it's not much of a solution. Let me know if this is the case on your laptop as well.

Let me know if you see the lines within the marked circles:

Yep, I see lines in the exact same places, even some places you didn't circle. But all of those spots show the lines for me. The first time I noticed it was when I was playing The Ship and looked at some dark wood textures: 10785

To be honest, I can sort of overlook it if its just a problem with all of them, which according to your 'research', it seems to be the case. Thanks a lot for responding!

And - yep, just tested it. Vivid mode makes it a lot less noticeable... and screws up the colors. lol

I'm glad to at least have found someone with the exact same problem. Do me a favor - go into your device manager, and see what model of display you have. Mine is CMO1720.

Also, let me know what happens if you end up sending it in for another RMA. Thanks!

AverageK
08-11-2012, 07:59 AM
CMO1720 here as well, and I remember the older LCD being the same model. I'm gonna try to get them to install a different model next time. It's just that I'm reluctant to send it in a third time (first time was a failed HDD within the first week! They then proceeded to lose my laptop for a few days after fixing it before they could send it back :p). I've had the laptop since the end of May, yet I still haven't been able to enjoy it at all! I'll call support once more before I schedule a pickup, and I'll let you know as soon as I hear anything back.

DaManWitDaPlan
08-11-2012, 08:02 AM
Well, it seems like a lot of people with the CMO1726 solved it by downgrading drivers... I decided to check nvidia's website for *normal* drivers rather than the beta verde drivers I'm used to always using :P

At the moment though, nothing is coming up for the 660m with Win 7 64bit... which is odd... I'm installing java right now (you can tell how new this machine is :P) so I can run the auto-check for drivers, as the website suggested...

AverageK
08-11-2012, 08:10 AM
I actually tried updating and downgrading the drivers several times, ranging from the oldest drivers on the asus support website to the latest beta drivers from nvidia, but nothing has worked so far. Since the problem doesn't occur while connected to an external display, I'm guessing it's not the GPU that's causing the problem, but rather the LCD itself. I have the 670m btw. As far as I can tell, nvidia hasn't released any official drivers for the 6xxm series yet. The only ones you'll find are either the ones provided by asus directly, or the beta drivers.

DaManWitDaPlan
08-11-2012, 08:19 AM
Well from what I can tell from other threads, there are people who had the exact same issue with other models and fixed it by downgrading the drivers... so yeah, unless you're getting a whole new model of lcd I don't see how an RMA would help..

To be honest, I'm pretty stupid when it comes to this stuff, but I figured I should ask just in case... is there any way for me to install the 650m driver that everyone is saying fixed their screens, for my 660m, and have it function correctly? :/ Even if its not really.. efficient, it would be nice to see if it is solvable with a software solution.

And how can we go about letting Nvidia know that this problem still persists?

Lastly, I'm still waiting for someone with the BBK5 to confirm that the issue is happening with theirs... or for someone with it to confirm that its not. If nobody *doesn't* have the issue, then at least I'll know that its not just my model...

I just got this notebook from a Best Buy junk-out exchange after my G71GX-RX05 went kaput... I'm damn happy now that I decided to get another warranty with this one... lol

CMO1720 here, 670M. I don't see how drivers can change this and there is no specific 650M driver. Or 660M, 670M and so on. I had the same drivers on G55 and G75.

The only people that might not be affected by this might be those using the LG 3D panel.

If I'll take this to warranty, Asus will just put the same panel in it and send it back to me. This is more of a recall problem. I don't think it will be easy.

With this driver http://www.laptopvideo2go.com/drivers/win7x64/305.53 you don't need the 67Hz fix. The flickr is gone. I had a feeling there might be a driver problem for the flickr since in Linux I had none at 61Hz (61Hz in Windows was the same as 60).

All I would like to know right now is if 3D owners have the lines or not.

I am unable to find a fix for this.

I'm not a photographer at all, but I know a thing or two about it. Most of my images still look fine, but some are just like very high compressed Jpegs and I don't understand why. They look like this only on G75's panel.

@DaManWitDaPlan: I downloaded those drivers, but it won't even let me install them. Says my hardware is incomaptible. However, the thread does sound promising as Nvidia have apparently been aware of the issue and working on a solution for a while. What I got from the thread is that the LCD panels themselves are weird, and require specific settings uncommon among "normal" LCDs, so the nvidia drivers are kinda exacerbating the issue. Fingers crossed for a fix soon. Looking at my downloads, the latest version of the drivers that I tried was the 304.79 beta, which didn't help at all, so I reverted back to the "official" 296.44 drivers. At least we can rest assured that we're not crazy and it's a real issue that other people are experiencing as well :P

@c_man: I see the horizontal lines in every one of those pics, though to varying degrees. I have a feeling that people with 3D-enabled laptops aren't experiencing this issue, since they have a completely different LCD panel. I don't think I have the flicker issue though! Just the ugly lines.

I've been searching the net for half a day and I have some info.

First, it is a specific Asus hardware problem with some Chi Mei panels.

Second, some Nvidia drivers make it worse. No driver will remove this problem, but some might make it harder to see.

I've read about how Nvidia had some sort of fix ("fix"= less obvious lines) before 304.xx drivers and how they plan to include this with new drivers.

I have tested the 304.48 beta and indeed there is an improvement. Lines are very hard to see on some images (this is why some said it was a permanent fix), not all of them. Image quality is better. But with 304.79, instead of an even better improvement, the problem returns and gets worse.

The driver Asus offers us is too old and no good with this problem in mind.

This is an old problem for Asus. I do not understand what can Asus do different from other manufacturers to cause this. I know what dither is, but I have no idea what I can change in the driver to get better image quality. I know where those values are, but it helps me very little.

There are few options here:
1. Hope Asus will push Nvidia to develop a driver for this specific hardware problem and that the lines will be gone as much as possible as I think there is very unlikely to vanish;
2. Buy another panel and change it - for US owners this is not that hard, for me it's impossible;
3. Asus recall to swap Chi Mei panel with something else - highly unlikely since there are so many laptops with this problem - simple RMA will not fix this if the panel is replaced with the exact same model;
4. Return it and choose something else - not an option for me anymore.

My only problem with this is that it will make photo editing a real pain. I will never know what exactly is the quality of the image. I don't really care about anything else.

Alright, so I contacted Asus Support once again, hoping that I'd get them to escalate the issue and perhaps let me talk with a case manager directly. The support guy assured me that this RMA will be handled as a multi-return and an escalated case, and that a higher level of service would be performed to ensure that the problem is acknowledged and dealt with appropriately. I'm gonna include more of those pics that highlight the issue as well as provide them with links to this thread so that they're aware of the extent of this problem.
I think I'll send it back later next week, as I plan on getting some use out of it before having it shipped out again :(

@c_man: Like AverageK said, we never had any flickering problem, just those solid lines. I did see lines where you mentioned in those pictures, albeit very faintly (I have the beta 304.79 driver),

@AverageK: Keep me posted. I wouldn't have even considered RMA'ing as an option, as I assumed they could only replace the LCD with the one meant for this model... If all seems to go well, that might have to be my option as well.

As you can see, most of it will look OK on your laptops even with the problem present. Most gradients are OK, little banding but it's rare.

Of course I would love not to have the "lines" at all.

I shall wait and see how you guys solve the problem. I wonder if I can install a 3D screen and at what price.

Maybe a driver that makes this less obvious will be out soon. Even if it means that only the Asus driver will work for us.

Asus driver is old, Nvidia has a few betas out. I hope Asus is looking into it. It is serious, even if I try to minimize it's importance.

Haha, I guess I owe you guys an update :P Well, I plan on calling them up tomorrow and scheduling a pickup for Monday. I haven't sent it in yet cuz I wanted to enjoy using it a little bit longer before having to part with it for another 2-3 weeks! I'm currently running the 305.53 beta drivers posted somewhere on these forums, yet the problem still persists. I don't plan on going back to school in September with a defective laptop, or with no laptop at all, so this has to be resolved one way or another :P I'll keep you guys posted.

No need to RMA. This is a driver issue 100%. The laptop is working perfectly.

I had A G74SX with this exact same problem (CMO1726 ChiMei panel). Nvidia fixed this problem with their newest driver for 560m. I had the laptop for 3 months until i had to RMA. After they ****ed up my laptop in RMA (i beg you don't RMA just for a driver problem. it's not worth it), I got a refund and bought a G75VW (CMO1720 ChiMei panel - it's the same panel type, just mate finish).

Again. Your laptop is not defective, it's just so new that it has no mature drivers. I'll try and contact Nvidia and see if i can get a fix on this. Please be patient.

@c_man i am also a photographer. Well... actually a photojournalist and i know how you feel and the frustrations we're all going through. Visually it's annoying, but the problem will go away with the next drivers. Unfortunately, we can't install the 560m drivers. They are not backward or forward compatible.

I wish so much you are right and that they will fix it. With latest developer driver release, the problem is simply huge.

ny2lond
08-19-2012, 04:02 PM
Here is the message I have sent Nvidia (fingers crossed they'll do something in the next driver release):

Put short, the problem is next:
Horizontal lines, 2 pixels wide and 2 pixels spaced apart. This creates a weird mesh effect on dark colours. This problem appears only on the ChiMei panels CMO1720(matte finish) and CMO1726(glossy finish) that ASUS G75VW respectively G74SW are equipped with.

This problem was solved for the 560m based laptops (ASUS G74) in its latest drivers from the GeForce site.

I recommend reading the forum posts from: http://rog.asus.com/forum/showthread.php?20249-Weird-faint-screen-lines-over-everything-on-G75WV-BBK5&p=140480&viewfull=1#post140480 , as there is another problem (flicker effect) which I managed to solve: http://rog.asus.com/forum/showthread.php?5536-Asus-G74-screen-flicker-(dark-backgrounds-and-low-brightness)&p=108570#post108570

At some point someone had a modded inf from Nvidia with some modified dither values.


Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images

Now that person said it fixed most of the problem, but he does not answer to PM. I would like to know what the heck did they do? All new drivers make problem worse, not better.

Hmm, well the laptop is scheduled to be picked up tomorrow (installed a second HDD to back up the first one, which took longer than anticipated). Do you really think I should hold off on sending it in this time ny2lond? And this should be a group decision, so c-man and DaManWitDaPlan, let me know what you think as well. There's nothing I'd love more than to keep my laptop for the time being, as I gotta admit, apart from this annoying problem, it's perfect! Do you think that I should give them a chance until the Christmas break to come out with a solution before I go ahead with the RMA? And why are more people not reporting this problem if it is indeed a driver problem? Wouldn't that mean that almost everyone else with the same screen model should be experiencing this issue?

c_man
08-21-2012, 06:56 AM
I did not see this until someone told me. The few games I have played did not have the right combination of colors. I can't see it while browsing my usual sites. I did not take any pictures lately. I keep brightness to 0.


So I guess it's possible under a certain routine, not to see it at all for a very long time. But the problem is there. Until I see it fixed, I don't have a take on this. I'm not sure what the problem is. It's almost impossible here to find a LCD panel. It can't be that hard to replace it once you have one.

About your question, what exactly do you expect from Asus? Same panel model?

ny2lond
08-21-2012, 07:45 AM
This is what ASUS will do: After you send it to RMA, they will test it, replace the TFT with another panel, with THE SAME MODEL, as the other panels are either 3D enabled or lower than HD as resolution
(so incompatible). In the end, the problem will still be there. Please trust me, as it's the same situation on a G74SX (this model also has a Chi Mei panel. Only difference, as it's also shown in the numbers, is that one is glossy - 1726 while the other one is matte - 1720).

Another thing. How can you explain that the sister panels have the exact same 2 problems? They both flicker and have the lines effects on dark shades of colour. The latest drivers from G74's 560M solved the horizontal lines problem. Still, you have to make my tweaks to end the flicker effect. I owned a G74SX before G75VW, so I know what I say.

Please, don't RMA for this small thing, that is also fixable. I had to RMA my G74 (broken BIOS\motherboard) and after I had it back, I had to RMA-it again for 2&1\2 weeks until I asked for my money back and bought the G75. They sometimes tend to break it more than it's already broken.

I just wanted to post to say that I have noticed this problem on my G75VW. I notice it in dark areas in certain games, or even certain images/website backgrounds. Other games don't seem to have the problem at all. For instance, I first spotted it in Fallout: New Vegas. I spun up Oblivion and Skyrim to see if I could spot the lines there, but couldn't reproduce them. Curious, since those three games built using different versions of the same engine.

I hope we can get a fix in some future drivers, as it is rather distracting.

I does not seem that complicated to replace the panel, but for me it's not an option. People in the US can do this easy.

Since it has been reported as resolved by early Nvidia drivers, I don't understand going crazy and swapping panels or RMAing. We don't have any non BETA drivers available directly from Nvidia, so I'd have some patience until they release some production drivers. At that point, if the issue persists, then push it on the Nvidia side. I doubt even after an RMA you'll have any better luck unless they happen to use a completely different panel.

I would like to bump the thread for a moment. I recently purchased my G75-BBK5, only a few days ago. I have the same issue described by the OP and others in this thread. I'm on the latest WHQL drivers, and the problem persists. I've tried changing my refresh rate, trying different drivers, etc. Nothing seems to work, and for now the main issue seems unsolvable.

However, I have figured out a means of temporary relief. I was up all evening fiddling with the Nvidia color control settings, and managed to find a certain configuration that will render the lines almost unnoticeable. This isn't the ideal fix... the exact settings leave the blacks washed out, as I've had to decrease contrast for this to work. Attempting to increase the contrast/decrease the gamma past these points will bring the lines back, I'm afraid. Either you'll have to accept the lines, or a lack of contrast. I really hope the issue itself is resolved soon, but until then, this fix ain't half bad.

Here are the settings I'm using:

Open your Nvidia control panel. Go to "Adjust desktop color settings", select "Use Nvidia Settings" and then input the following.

To make the lines almost completely gone:

1. While "All Channels" is selected, set Contrast to 7%, and set Gamma to .57.
2. My monitor had a slight blue tint. To remedy this, do the following: Switch "All Channels" to "Blue" and set brightness to 60%. Switch to Red, set Brightness to 65%. Switch to Green, set Brightness to 65%.

To increase contrast (darker blacks), while keeping lines as limited as possible (you will be able to see them now, but you won't notice them easily):

1. While "All Channels" is selected, set Contrast to 25%, and set Gamma to .55.
2. My monitor had a slight blue tint. To remedy this, do the following: Switch "All Channels" to "Blue" and set brightness to 60%. Switch to Red, set Brightness to 65%. Switch to Green, set Brightness to 65%.

I personally use the second option.


Note these settings (for whatever reason) don't save on reboot. You have to reapply them when your computer restarts. At least, that's how it was for me.

Hope this helps someone... if anyone has any news or developments for this issue, please let us know. I'm trying to decide whether or not this is worth returning my laptop over. :(

ny2lond
09-15-2012, 10:56 PM
With the latest drivers, the lines are still there, but a lot fainter. Interesting enough, now they show up also on the grey background of the quick reply box.

I run on standard settings with the 67 Hz fix (that annoys me more than the lines). Looks like I'l have to file another complaint. I can't do the colour fix as I work with images and I need correct colours.

@ rilez: it's not worth to return the laptop for a bad driver issue. They managed to reduce the lines, but they are still there. This kind of proves my point.

Hi, so i have had 3 g55s and 1 G75. the first two G55s had broken parts, i didnt really pay attention to the screen that much, but i returned them. When i bought the G75-BBK5 it had the screen lines and i was annoyed so i brought it back. Since the store at which i bought the g55s were out i bought another one online and it also has the damned lines. I would really like to know how to get rid of them. Im quite pissed because of how many computers ive gone through. Is it known to be hardware or software?

Definitely not an issue with dead pixels. The area affected changes when you change brightness/contrast/gamma. Mine was there before I even changed anything. Used the tool you posted just to be sure, but it turned out fine.

It seems to be a hardware issue. It's not driver related. Just because certain drivers change the visibility of the lines, doesn't mean they're causing them. Uninstall your Nvidia drivers and use the default Windows PnP, like I did. You will still see the lines. Just like changing color settings might make the lines better/worse, the drivers are the same way.

I've talked with other owners of the G75. Some have this problem, some don't. I'm bringing mine to Best Buy for a RMA tomorrow. Hopefully ASUS can sort this. I just wish they would post in here.

I love this laptop to bits :(. I'm not keeping it if this can't be fixed, though.

If the drivers aren't causing the issue, how is it not a hardware issue? As you just said, it could be the difference between the 660m and the 670m. That would point to a hardware issue.

ASUS won't admit it's an issue, they're RMAing for it and putting the same cheap, junk monitors in as they have already. It's not a problem they are willing to fix.

Personally, this (my G75VW-BBK5) will be my last ASUS product. They're not getting any more of my $ when they sell us inferior products like this and then refuse to take ownership of the problem. Looks like MSI is the way to go.

Hi everyone!

Got an Asus G75VX T4109H which also has the Chi Mei CMO1720 panel. I was hoping to get a machine with the AUO B173HW02 V1 instead, but Asus seems to keep the Chi Mei in the batches :(

Nvidia Driver: 307.07

It's quite easy to spot the lines from the Chi Mei panel at this page: (in the first few boxes depending on settings used):
http://www.lagom.nl/lcd-test/black.php

As others have mentioned, it's possible to get rid of the lines by changing brightness, contrast and gamma. But this will also alter the black level of the screen.

If you intend to do any type of graphics work on a laptop, I would suggest that you stay away from the Asus G74/G75 (except for 3D models).
Since Asus doesn't seem to offer a matte 3D screen for the G75VX, I will probably just get a refund.

This might not be useful since my machine is a G73sw-xa1, and not a G75, etc., but maybe it'll help someone. I had faint horizontal stripes in the dark areas of the image, each about two pixels wide. Adjusting the nVidia color settings would simply change which area of darkness the lines showed up in. No flickering, but same story as many of you.

Asus has two drivers posted for my machine: v267.54 (Asus's number V8.17.12.6754) and v296.16 (Asus's number V8.17.12.9616). The earlier driver does not show the lines - at all. They're entirely gone. I was convinced it was a hardware issue, too, until I tried the older driver. Now I think perhaps it's a bad interaction between the driver and the panel. That would mean Asus could fix it but nVidia (directly) isn't likely to. I keep wondering if it's some sort of dithering gone wrong.

I wish I could offer more help because without the lines, once the gamma and brightness are set, this display is really beautiful. But we'd need someone with serious skills in drivers, hardware, and low-level programming/hacking to dig in. Not sure that'll happen. If you have a G73, try the older, 267.54 driver from Asus. Everyone else, best of luck! I feel for ya. :/

I just noticed today that i had those lines when i started up EverQuest 2.
And that is how i found this thread.

I opend paint and filled the screen with black and the lines where there, i closed everquest 2 and the lines where gone!!!
So i started everquest 2 again and as soon as the monitors flickers over into the game the lines where there again, even if i run the game in windowmode but as son as i quit the game my monitor is back to normal, how can this be? :) using 310 drivers atm.

Solved it !!!! :D
Went into the nvidia control panel and picked "Adjust desktop color settings" and picked "use nvidia settings" and moved one of the sliders and the lines where gone, its like the game where controlling the gamma and color settings or somthing like that.

Well i gues you can say that i did not rly solved it, i just found a way to get rid of it, change the light condition and you get rid of them or atlet you cant see them.

I have the same issue in my G75-VW and it's not a panel issue at all as I get the same lines to my TV via HDMI connection. It's something else. Either it's the GPU or Nvidia drivers.

I have the same problem for the most part, except my banding is all vertical. It makes games like EVE look TERRIBLE (as the dark background is where the banding is most prevalent).

Has there been any fix? Is my vertical banding hte same problem the rest of you are experiencing? It really bothers me, as I remove almost all white window colors from my laptops as I find darker colors to be softer on my eyes. Unfortunately, everything that isn't either very bright, or black on this laptop appears with these vertical lines all across the screen.

Guys i managed to fix this problem using the latest driver from nvidia. It would sound stupid, but i just went to the nvidia control panel, change
resolution, customize, create custom resolution, leave as is. Then test and hit OK.
That's it, give it a shot guys (already sent it 3 times to RMA and got always the same problem).

What latest driver? I run signed 314.07 and I'll give this a try. With this driver the flickr seems to be gone.

I'm using the signed 314.07. In fact are not gone with this driver but creating a custom resolution fixes that problem. However, as soon as i change resolution in a game or in windows the flickr will be back. So it works only with the native resolution (1600x900) for me.

Edit : Did anyone manage to tell Asus RMA people the right words to get it fixed ? I sent it 3 times to RMA, and except the fact that the lappy was put to factory setting everytime no improvement was there for that problem. I explained them the problem with all the existing manners, still they don't seem to understand.

They have a fix for it. And its nothing less then Asus engineering at its finest.

This comes direct from Mike_Lu@ASUS

"please change your backgrand setting, if nothing help, you can send back to asus service center to check it or replace it if you are in warranty. "

Why im at it i think i can be a Asus engineer now. Lets put some fix's out.

Loud fans?

Hum to your self, Turn your tv up or just ignore the sound.

System locks up every now and then?

Use the computer less.

Dead pixle?

Dont look at it. Or only display a black screen

USB port not working? Use another one.


Asus understands this display issue and they worked for months and had their best engineers working around the clock to come up with a fix for it. But it must be preformed by a trained Asus tech since this is very complex and only 3 people in the world know how to do this. change your background setting. Just chance it to all white or one with white lines and the problem is fixed.

I know that. I know its a problem with the cheap welfare LCD panels they used. If you dig deep all the displays with the lines come from one plant the other perfect ones come from another "Same company" Even the VX has this problem. But Asus knows how to fix stuff so just change your backround till you dont see it or dont look at it lol.

This is Asus's version of the awesome Apple our phone is perfect you are just holding it wrong. And really with the huge fan boy fallowing Asus will never fix this issues if you are lucky they will replace it with one that dont have it but chances are they wont because they dont care. Because if you make a topic like this some 13 year old fan boy is going to make 10 about OMFG my G7% is soo l33t its like the most amazing system ever its the worlds fastest super computer other laptops wish they can run games like the G75 its so fast best deal in the world the next best system is $4,000.

I'm hoping that Nvidia will release some kind of fix to this (i'm i hoping too much?). I will sell my G75VW as soon as it gets fixed, i just don`t want to screw up people by selling them a good looking lappy with crappy display lines.
Thinking about a last (4th) RMA but im really expecting more problems than fixed ones. Are there any kind of policies if your laptop is not fixed after 3 RMAs ? Like put it in a prioritized line of something like this ?

I'm going to my 3rd G75VX, and at this moment Portugal have no stock.
I just will stop sending to RMA when one comes without issues.

Why is it that you all dont just get it resolved with the place you bought it from?
Is the consumer rights that bad in the US?
Here in Denmark, you have 2 years where it is expected to work, if not get it repaired (go trough the company you bought it from, let them deal with asus) (the company may tell you to deal with asus directly but just DEMAND that they deal with them, its not your job as a buyer)if they cant resolve the issue after 1-2 tries. you can DEMAND to get a replacement from the company you bought it from (let the company deal with the issue of getting the payment for replacement unit covered from asus)
------
the mods on this board are horrible, I know they may not be native English speakers (neither am I) but they give crap advice, advise to RMA it to repair center, get drivers from homepage which are none exsisting, unable to read what the problems are and give advice to stuff that isnt even written.
And the mods seem to be here just for general stuff, like ban people, keep peace etc. So its almost pointless asking for help from them on here.

What are you looking for? Why do you need a modified BIOS? Flashing uncertified BIOS's is dangerous, as failed flashes are not covered under warranty.

Quick question guys, do you think that replacing the screen with one of these in ebay : http://www.ebay.ca/sch/Computer-Components-Parts-/175673/i.html?_from=R40&_nkw=g75vw would fix the problem or is the source somewhere in the motherboard ?
The strange thing is that my laptop did not have this problem when i bought it, then once back from my first RMA about a Bios problem they were apparent, so i guess they did not change the screen to fix the Bios lol.
Your opinions are welcome and screw Asus warranty.

Just tried it slayer. Those drivers are kinda old (311.44). And unfortunately, they didn't fix the problem at all. Try reducing the brightness from the Nvidia control panel to 45% instead of 50%. That seems to be the best compromise for now.

Hey man, unfortunately it's been two years for me with the G75 and there's still no fix for it. And I'm assuming there never will be. The fact this issue is still present on the latest models shows that they don't care enough to fix it at all. My advice is, if the lines are bothering you a lot (and they should), then return the laptop to the store you bought it from and get your money back. The chances of this issue ever being fixed are slim to none.

Hey guys, just a heads up, but I think I might have found a way to fix the problem. I have the original matte display, and tried to replace it with a glossy, I ended up getting a Chi Mei and had the lines issue. Luckily, I was able to get the seller to switch it out for a proper LG Phillips LP173WF1(TL)(C1) screen. The screen will be here either tomorrow or Monday. I will let you guys know if the lines disappear with the screen.

Apparently the Chi Meis have a 650:1 contrast ration, and the LG has 500:1, but if it gets rid of my lines issue in my G75VX (670MX GPU), I will report back.

Everyone I am happy to announce I have FIXED THIS ISSUE. First of all, understand I have had both a Chi Mei and LG panel, as well as my stock matte display.

The matte display had no issues, except for dead pixels once I dropped it. Then decided to upgrade to glossy.

I experienced both the flickering issue and lines issue with my previous glossy Chi-mei. I was able to fix the flickering by setting my refresh rate to 96 hz, but always had the lines issue. Playing with the nvidia color settings would could hide the lines a bit, but would destroy contrast and gamut.

I ordered a LG Phillips LP173WF1(TL)(C1) screen. This is the EXACT model screen I was able to pick up online, for less than $100 with shipping. I had hoped making the jump from Chi Mei would fix the issue.

At first, I could still see the the lines. They were MUCH less pronounced then the chi mei panel. Even doing a clean driver install of the latest geforce drivers (version 347.09).

However, once I overclocked my refresh rate from 60hz to 96hz on this LG panel, the lines have COMPLETELY disappeared! The lines still show up at 72hz, so I am staying at 96hz.

Again, using one of these LG Phillips panels, doing a CLEAN install of the 347.09 Nvidia drivers, and overclocking to first 72hz, then 96hz, you can fix. Some screens might work at 72hz, which will increase the life of the display, but you should get 5+ years out of the panels even at 96hz. Plus, you get some extra FPS in those games.

I hope this can help others -- of course, this thread and others are probably dead, but still nice to have found something that works, for me.

And just so you know, I have my GPU volt modded and overclocked. So overclocks don't seem to effect this fix (Currently at 1.1 vcore and 1 GHz core, 1.2 GHz memory on my 670mx!)

Note: I choose multiples of 24 when overclocking. This allows for proper video playback of 24 fps content on this displays without losing a frame every now and then in madvr for video playback.

This panels can overclock this far, I had my Chi Mei at 96hz for over 2 years with no issues. Again, the lines are COMPLETELY GONE.

Pick up one of these screens. I got no dead pixels on mine, and
