Hello all,
I know there have already been topics concerning the G750's screen. I'd just want to know if others are also seeing a pattern of dark vertical lines in some shades of grey or sometimes other dark colors.
It's only visible when you look close to the screen. I have a G750JH (so a 780M) and I am using the stock 311.83 drivers (which are working well otherwise and have never crashed).
I got an AUO matte screen (non-3D).

I tried the 326.80 and 327.23 drivers : with these, the effect seemed different : not really vertical lines, but more a "grid" effect. So I reverted.
Again, it's only visible on some specific colors/shades.
It has, I think, nothing to do with the "other" line problem (horizontal "waves") where people just created a custom refresh rate for the monitor. (for example, I'm at 70 Hz)

Yeah, I have sensitive eyes.

So, is it the screen, the GPU, or the drivers ?

It's a pity I like the screen of my 2005 Dell XPS M170 much more...

Waiting for your feedback.

Uninstall Asus Splendid software, reboot.

Use the Nvidia Control Panel and create a Custom Resolution of 1920x1080 at 100hz (or 85hz, as some have said works to get rid of the lines).

Those are the only tricks that have worked for most people. Please let us know how it worked for you. I have the Chi Mei N173HGE and removing Asus Splendid was enough to bring clarity to the LCD for me. But, I like the smoothness of the image at 100hz.

What version of Nvidia drivers do you have installed? I used to have faint vertical lines on dark shades of gray but they disappeared after updating nvidia drivers.

Hello,

thanks for your answer.

I'm in France, so I'm at work at this time. I'll try your suggestions later.
As I said, I use the 311.83 drivers. I already got rid of Asus Splendid.
I tried the custom refresh rate of 70 Hz, but maybe it's not enough? (because you speak of 85 or 100).

Cheers,

Pierre

Yes almost evertone have those lines, its a software issue because with 314 drivers the lines turn into small squares instead, bit more acceptible to look at imo :P

Also use 67hz or more to get rid of low light refresh "waterfall" effect, its a new machine and i dont doubt some updates will solve these issues^^

Yes, playing with the refresh rate gets rid of the eye-straining waves. (starting at ~ 70 Hz or so)
But the vertical lines patterns never disappear.
The other drivers, as you say, Rawpure, transform the pattern into "squares". Unfortunately, I found this one being worse than the lines : it looked like a "dithering effect" and was sometimes almost as if the GPU worked only in 16 bit colors (remember the 3Dfx Voodoo cards?).
That's why I have gone back to 311.83

It would be interesting to know if the 3D screen shows the same : then we would have proof that it's GPU and/or driver related.

What you describe made me realize you may only need to do LCD / Display calibration. Part of the Calibration routine is to change contrast / gamma settings that affect "seeing things" in grey areas - you adjust to remove them.

http://windows.microsoft.com/en-us/windows7/calibrate-your-display <== Instructions for Win7, but gets you there in Win8

I don't see lines/hash/cubes in grey / dark areas...except in places I assume I am supposed to see them, like in the scroll area of my Firefox theme.

27723

There are also Nvidia settings that you can use to adjust the display: I turned of Dynamic Contrast, but it may work for you.

I have the gamma/color settings set to defaults right now, doing other things, let us know what worked for you if you choose to adjust to try to get out the lines/hash/cubes.

27721

27722

I also noticed that AIDA64 has an in depth Monitor Diagnostics feature, under Tools:

27724

There is also a newer 331.40 Notebook Beta Nvidia driver set, which I have been running under heavy usage / load, without problems.

If you hook up an external monitor, and do see the pattern in the external monitor, it would point to the card / driver and not the laptop LCD.

Hey, thank for your efforts.
Well, I've hooked an old CRT screen to the 750JH with the VGA connector : as expected, the line patterns don't appear there. So it's obviously the screen (knew it). Things like this are more noticeable on matte screens, I think, because of the AG coating.

Some people are more sensitive to this than others. I even got rid of an Eizo Foris (I know it's a shame) because I couldn't stand the "crystal effect" of the coating. Now I've a Samsung S23A700D (120 Hz) for my actual desktop computer, and it's just perfect. Only bought it because it's GLOSSY. I don't use 3D and I don't use refresh rates over 60 Hz on this monitor.
Luckily, 3D screens are still glossy, because the antiglare coating "steals" a lot of light and good brightness is needed for 3D. They can put characteristics like 100000:1 contrast ratio (ridiculous) or 500-1000 candela/m or so, but when you SEE the screens, you notice the difference.

To watch DVDs, I still use a CRT monitor (Mitsubishi Diamond Pro 740SB, from 2001 - my old 67 TXV died years ago) with an old desktop computer (PentiumIII-1000, Win98SE, MSI GeforceFX 5900XT AGP, SoundBlaster Live 5.1) and WinDVD4 platinum : old but good :-)

Pierre990429, too bad the screen isn't working out for you. The laptop is otherwise awesome. Different screen manufacturers are being used for the G750 and some respond better to adjustment.

You say AUO, but what is the full part name for your screen?

Mine is a Chi Mei N173HGE CMO1720 HC9GK_173HGE

27842

Do you have the Windows Desktop Magnification set to the default 125% ? I prefer the non-magnified view and always change the Desktop Magnification to 100% as one of the first things I do when configuring Windows.

I have an AUO 219D, reference B173HW02 V1.

You're right, for me, it's the only flaw. A screen's "quality" is something very subjective.
Funny, I've seen forums where people complain about the AUO and the Chi-Mei but say that the AUO is the "least bad" of both.
I guess that once you've been "spoiled" by a good glossy screen (sharpness, vibrant colors), you can't go back.

If only I knew how to disassemble the bezel without destroying something by accident... :(

I really wonder why you can't (it's almost impossible, except in some rare countries, at very specific resellers) find the G750JH with 3D-screen ? does ASUS have problems ?

G750JH, just bought. Faint lines are there; well, actually, they're pretty darn visible, between pixels. Anyone who doesn't see them needs to get their eyes tested, or already has - in which case, they should not be going round saying "derp, looks fine to me".

It's disgusting that ASUS slap such a sub-par screen on such an expensive machine, that is trumped in quality by pretty much any lappy under $1000. I'm going to contact them to ask if they can replace it for me, because from where I'm standing, this is a fault.

Anyone happen to know where I can get a good replacement (preferably glossy) screen?

Also, the fact that the SSD cannot be changed out, mouse buttons have WAY too much travel, clacky keys, terrible speakers, I'm getting some awful buyer's remorse going on over here.

ASUS: Y U NO MAKE LAPTOPS LIEK USED TOO?!

10-20-2013, 06:46 PM
Yeah, I don't understand it either. The lines are SO obvious.

I already bought a LG glossy screen (LP173WF1 TL C1) , just want to know how to open the bezel without destroying it : I removed the 4 screws at the corners, but then what ?

Yesterday I managed to restore my Dell M1710 by changing the (fried) graphics card : I found a Dell refurbished Geforce Go 7900 GTX, and it works. Wonderful.
(I found a great video : "How to Replace the GPU in a Dell XPS M1710" , it helped a lot)
The M1710 glossy screen is a LG-Philips LP171WU1 one, it's really GREAT, (and no need to do a "trick refresh rate" over 60 Hz) that's why I bought a LG screen for the G750. I just want to install it....................

Huwbutts, we are not saying "derp, looks fine to me", we are saying we don't see the lines in our screen images. We have looked.

Noone has posted an image where they see the lines so we can compare.

I have seen screen anomalies before, and I know that just because I see them it doesn't mean someone else is going to see them. I have tried showing people screen issues before, pointing right at the screen, and they don't see them. It can be frustrating.

I have looked closely at the screen, at a lot of images that should show problems, but I don't see any. It could be my screen doesn't show these lines, but yours does.

Please give us a couple of URL's/images and indicate a location on the page to look at where you see the "faint lines between pixels" so we can check on our screens. Please use the Windows Snipping tool / Paint to indicate the area of "lines between pixels"

How close do you need to put your eyes to the screen to see the lines? How far away are your eyes from the screen when the lines stop being visible...?

Here are some screen tests, if you see the lines anywhere, please point out where so we can look on our screens.

This URL is the middle of the test, on a likely test page that will show the problem, if you don't see it there check the other pages in the test, or find a test online that shows the problem so we can check on our screens:

http://www.lagom.nl/lcd-test/gradient.php

This test will show flickering at 60hz, create a custom resolution setting in the Nvidia Control panel and increase refresh to 85-100 hz (highest stable for your LCD) to get rid of flickering. 100hz is stable for my Chi Mei screen.

http://www.lagom.nl/lcd-test/inversion.php

Have you tried any of the fixes that others have found useful? I have summarized a few below, but look around in the forums for solutions that others have found useful.

If you haven't Uninstalled Asus Splendid, uninstall as it has caused screen issues for some.

Change Windows desktop size to 100% from Windows 8 default of 125%, magnification can put color anomalies into color regions. Windows Control Panel ==> Display

Update Nvidia driver to latest 331.40 Beta - some say older versions have lines in color regions, updating changed distortion to something more/less pleasing.

Adjust color balance either by hand, or get/make an ICC profile tuned for your screen, if you have a Chi Mei or Samsung, the 6500k/7500k profiles here work great.

There are screen replacement articles sprinkled throughout ROG. For some the screens aren't the best, and so they replace them - you need to remove 17 screws from the G750 laptop, pop the screen off the laptop, and then pry it open - needless to say it is probably best to find a service that will do the screen replacement for you.

What do you mean by the SSD cannot be changed out? What is stopping you?

You can remove the HD or replace the mSata SSD's. HD"s are glitchy, slow, and generate heat/noise, I removed mine.

You can replace the msata drives with larger/faster mSata drives, like I did on another laptop. You will need to image the original SSD config and restore it to the new pairing of mSata drives.

Pierre990429, we never thought to exchange images/url's to compare on our screens what you are seeing with what we are seeing. Please post some URL's / screens / images with annotation so we can compare on our screens.

Someone on ROG must have used a screen replacement service that they can recommend. I have used laptop repair places locally to replace damaged screens, and it isn't such a big step to ask them to swap a good screen with a better screen - they may even credit you the value of the old screen.

Googling around I found these places, but I haven't personally used them - there are likely others in your locale:

Someone asked earlier. I own a G750JX with the 3D screen, I did notice "lines" in some grey gradient areas but it's hard to replicate, I can't seem to find the exact pattern. Pretty sure I saw it in youtube or something. This happened to me both at 60hz and 120hz.
I have recently updated the nVidia drivers to the latest so I'll have to see if I can find it again.
At any case, while I am annoyed by such things for me , I encounter it very rarely, so it's not a big deal. If someone faces this issue daily because it's on their program or or favourite website, I could see why this would drive them nuts.

Edit: I tried the tests above me like inversion and they are fine, for example.

HMScott, I really appreciate how you try to help.
I may sound bitter, but as a matter of fact I'm disappointed by this surprising flaw in an otherwise perfect laptop.

Ok. I have a French Windows 8 G750JH, with Geforce 780M. Using the 311.83 stock drivers. I have an AUO screen (60 Hz, matte, non-3D).

Take this link : http://forums.bethsoft.com/forum/180-pc/

Here is a detail of a screenshot :

http://i169.photobucket.com/albums/u229/pierre_67/Bethesda_forum_screenshot_zps40312661.jpg (http://s169.photobucket.com/user/pierre_67/media/Bethesda_forum_screenshot_zps40312661.jpg.html)

On the Asus G750, I can see the lines. On the Dell M1710, it's ok.

Now, here are photographies of my screen, at different distances :

This precise page is a very good example. I assume you can see the vertical lines in the last images.
If you look closely, you can already spot them in the second image. It's rather hard to photography (and the light wasn't optimal), but it's really obvious when you are sitting in front of the screen.
I am typing this with my Dell M1710 (LG truelife WUXGA 1920*1200, 60 Hz, glossy) , and I only see black and different shades of grey (in the Bethsoft link, of course. The screen photographies show the flaw) . No lines. No pattern whatsoever.

I tried to "upgrade" the driver (326.80), but the pattern was only "modified" : not sure the lines were really gone, but instead, there were little "spots" in grey areas.


HuwButts, please tell us which screen you got and which drivers you are using (I assume the 311.83 ones).

I think Asus shipped Chi Mei in the USA and mostly AUO in Europe, but I could be wrong.

Frido, this happens with 3D screens too ??? (and Geforce 770M) Could you check, please ?

Pierre990429, in the extreme magnification I can see the vertical and horizontal screen elements that for all of us blend together when viewed unmagnified..They stand out when magnified, I see that. But, Pierre990429, you are magnifying it way beyond what I would normally even consider - unless I was playing around with my DSLR and a telephoto lens :)

I don't have a camera to do the same with my screen right now, but I would be surprised to *not* find something to complain about when magnified that much. Pixel color groups are gonna start showing if you magnify any further :)

I went to the page you magnified, and it looks clean at 100% non-magnified size. I tried all 3 ICC profiles to see if changing that would cause anything to pop out, but I see nothing but a clean background image.
http://forums.bethsoft.com/forum/180-pc/

Does anyone else see anything odd on their screens at that URL at normal 100% view, or magnified - and how much magnification did it take to make the screen elements stand out?

Sorry it bothers you Pierre99049.... did you check around for a repair shop that can swap screens for you?

Maybe these lines are only visible on the AUO screen. You all seem to have the Chi Mei ?

Could an AUO screen owner tell what he sees ? (maybe it's geforce 780M related, but I doubt it)

Except for those who "see" the lines. (even without "magnifying" : just looking at the screen)

I just marked the bottom of some lines in red. It has nothing to do with the "space" between physical pixel elements of the screen.

Yes, I'm about to search for a place who could swap screens.
What bothers me, is that there is no official ASUS comment about this.
And I was able to replace MYSELF the screens of 2 Dell laptops, but not this one :
Could anyone tell me HOW I open the bezel? As I said, the back and front plastic parts seem really put tight together.

What did you find wrong with the Dell screens, and what make model were they replaced with?

Do you notice a particular spec in common with screens you don't like (other than the visual one), and something in common with the spec's in the screens you do like?

Please do come back and let us know what you end up doing to fix/replace the screen.

Nothing wrong with the Dell screens, but my Dell laptops are from 2005 and 2008, and one recently got several vertical lines of stuck pixels - common issue with laptop screens, at least LG models - , so I had to replace it (twice, because the first replacement - pre-owned screen - was also faulty - well, much better : had only 1 vertical pink line) .

http://i169.photobucket.com/albums/u229/pierre_67/M170_eacutecran_naze1_zps77609de7.jpg (http://s169.photobucket.com/user/pierre_67/media/M170_eacutecran_naze1_zps77609de7.jpg.html)


Dell used very specific screens with each its "inverter". For example a screen of a M1710 won't fit a M170, even though they are very similar models and the connectors are the same. You have to find old pieces on Ebay... These are old screens (16/10 ratio, CCFL back-light, not LED - I wonder if it wasn't better) with a different connector as the actual ones. And there is a power connector.
(yeah, many sellers offer "compatible" screens, but you don't know what you get)
Dell used to ship their models with Samsung or LG-Philips screens. Most people liked the LG ones better. Both were glossy and "TrueLife".
Of course, many sellers offer "compatible" screens, but you never know what you get finally.

But for my desktop (I7 2700K, Win 7 64), I got a Samsung , glossy , SA23A700D, 120 Hz, 3D capable (with DVI-D cable), but I'm only using it at 60 Hz. It's really great. (couldn't find a glossy LG model)

I like glossy screens (otherwise it's like looking through a muddy glass), with sharp and vibrant colors, no flicker, no waves, no weird pattern "in the pixels".


I still didn't change the G750 screen, as I'm not using it much now. (typing this with the old Dell - WinXP)

I still didn't change the G750 screen, as I'm not using it much now. (typing this with the old Dell - WinXP)

The http://www.samsung.com/us/computer/monitors/LS23A700DS/ZA monitor looks great, but if you back up to 3D monitors in that site, it looks like Samsung doesn't offer any right now? 0 matches for 3D on US site http://www.samsung.com/us/computer/3d

I wonder what is up with that? New models coming?

Have you tried running 2d at 120hz instead of 60hz? Seems like a big win is waiting for you to unleash...

Please come back and let us know what glossy screen you find for the G750 that ends up fitting/working.

Hmmm, the only 120 Hz (3D) Samsung monitor on the French site is the S27A950D : http://www.samsung.com/fr/consumer/it/monitors/led/LS27A950DS/EN

Available on Amazon.com : http://www.amazon.com/Samsung-S27A950D-27-Inch-Class-Monitor/dp/B004Z75LX0/ref=sr_1_1?ie=UTF8&qid=1382865260&sr=8-1&keywords=s23a950d

A bit expensive and too big for me (23" is the ideal size)

My S23A700D is on Amazon US too, but through third party sellers/offers :

Or this one : (750D) :

http://www.amazon.com/Samsung-S27A750D-27-Inch-Class-Monitor/dp/B0059031XE/ref=sr_1_4?ie=UTF8&qid=1382865211&sr=8-4&keywords=s23a750d


I haven't tried 120 Hz in 2D (but I must have the DVI-Dual cable because few programs - mostly "demos" from scene.org - choose automatically the highest refresh rate declared by the monitor , and with a normal DVI cable, it doesn't work : black screen) : I always have Vsync ON , and I guess it will stress the graphics card less (Geforce 580 GTX - I bought this in November 2011, for Skyrim).
I'm not sure if I would see a difference. And some games (like Skyrim) have something like a stuttering bug if the refresh rate is too high (64 Hz for Skyrim).

Pierre990429, your GTX580 should drive it fine at 120hz in 2D. As for game support, you can limit the FPS for those specific games with high fps/hz issues, but for 99.9% of the games the GTX580 should run many at 120+ FPS. And, like you said your DVI-D seems to be working ok at 120hz 2D, so give it a try :)

It may be that Samsung is switching over to new 3D models coming up, and that is why there aren't any listed:

Hi. I'm from German. Bought the Asus G750JH before 2 months. The Panel is the AUO. And i coukd see thus vertikal, fine lines between the subpixels. My Eyes are very sensitive, too. But my wife didn't see it. I see the Lines very clearly at a white Background, like in Windows Explorer. It's not a driver issue, its the panel himself, you can't solve it. But what you could, is to change the panel. But think about the warranty...

Hello,

yes, I've seen at Amazon.de that users are experiencing the same as I do. You describe it very precisely.

Schade, eine so teure Kiste und dann dieser ScheissBildschirm.

I want to change the panel, indeed. Searching for the exact procedure.

Pierre,

i thought it's was impossible, but test the new nvidia 331.65 WHQL of the official Geforce.com Site. i Installed it today, and it seems it is very better than before.

I din't see the lines. Have pot the digital color adjustetment to 60%, and now it's ok.

Edit: ok, i can see the lines furthermore, but now only a little bit on grey background. But it disturb me not much.

Hello Mirovb,

please check the previous pages of this thread : I already realized that the 326.80 driver was modifying the lines and transforming the line pattern into a "grid" : looks like there are "little dots" in the textures. Could you please check and see if it isn't the case with 331.65 ?

Some people report troubles with 331.65 (boot delay) ; did you experience it ?


(in case you wonder : I'm French, but I speak other languages as well)

Ok, tested 331.65.

1) the vertical lines in some greys are still there.
2) just launched A New Dawn, to test speed and GPU temp behavior, and it wouldn't start in full screen anymore and was slow ( and it's a Nvidia Demo !!!)

>> Back to 311.83 (system restore point)

Thread's a bit old, but I wanted to report the exact same problem - and yes, unless you are far away from the screen it's clearly visible - on a Dell M6600 machine with a 7970M. So not an nVidia issue.

I tried 90hz on screen in NVidia.. it didn't work.

Tried 100hz, didn't work..

Tried 120hz, pushed too far, as the screen went rainbow at the bottom.

Chi Mei.

If you have the feint lines during blacks, you CAN ignore it... infact, you can NOT see it, by having your eyes further than 2 feet from the screen. The lines then just.. meld into the picture.

Shame, I fit into this category with my brand new ASUS G750JZ :( Why me!
Linear, most visible in Windows and less in games as there is more going on.
Also some kind of rainbow waves horizontal raindow feel.
But to be honest, I had 5 x G75 (3 different models, from 2 different stores) and 1x G750, they all had that.

I see you found this thread.
Well, that settles it : the new G750 are also affected.
Can you tell me what is the "default" Nvidia driver version ?

On the latest ones, the lines are transformed into "grids" (or "little squares").

Just to tell you : this is not screen related; Must be a motherboard and/or Geforce chip issue.
But I never saw it described on Alienware forums, for example.

Move your eyes further away from the screen...the laptop / built-in keyboard paradigm has us sitting too close to the screen.

I don't see the lines, but I use a wireless keyboard and trackpad, so I don't use the built in keyboard and sit right on top of the screen.

Would you put your desktop monitor that close to your eyes?, or do you push it back further from your eyes when you put the keyboard and mouse between you and the screen?

If you sit as close to your monitor as your laptop screen, you would start to see the individual distinct elements that make up the smooth image you see when sitting back further.

There are plenty of mentions of faint lines on Alienware screens too :)

yeah, some old Alienware M11 models seemed to have a similar problem. (?)

but nothing since. not a single complaint for the M17 or M18 series. right ?

Rahul, are your lines vertical ("AUO' type) or horizontal ( "ChiMei" type). Either way, the latest drivers from Nvidia transform the lines into a "grid". It's up to you. Personally, I felt the "grid" was worse to my eyes.

No other fix, sorry. (and probably never, since it's a hardware issue)

KoolASUS. it makes me wonder what is going on with that. I have looked at a lot of Alienware screens, and they look no better than the Asus screens. Are people more likely to complain with a reasonably priced laptop vs. a stratospherically over-priced laptop?

Doing a search on their Alienware forum turns up no hits for "vertical lines screen" or "horizontal lines screen", whereas on the rest of the DELL forums, Laptop in specific, there are 1477 hits for "vertical lines screen" and 749 hits for "horizontal lines screen". Odd.

Comparing price between the Alienware and Asus config, same parts vs same parts, gives one pause - back away slowly from the Alienware purchase page, and quickly browse to the Asus newegg.com page :)

An Alienware M17 configured as close to the Asus G750JZ-DS71 as possible: $3399, vs $2269 for the Asus G750JZ-DS71 from newegg. And, there isn't even a RAID0 boot option available for the M17 from Alienware, so I couldn't configure an M17 similar to the Asus G750JZ-XS72, which is only $2799 on newegg.com

So the Alienware config is $1100 more than the Asus config.

Push back another foot from the Asus screen, and the faint lines disappear out of focus, and the 1100 greenbacks come into focus :)
