Hello All,

Since i got an R9 Fury i've been seeing a strange blurry line down the middle of my monitor, and also some lines/flicker down the left side of the monitor. I can be fixed
by changing hz or rebooting, and before you know it.. its back again.

I read in this forum http://www.gpforums.co.nz/threads/513129-Asus-MG279Q-issue/page2 that Nvidia users using the PG279Q saw a similar problem and that is was
fixed with a firmware update:https://rog.asus.com/forum/showthrea...G-SWIFT-PG279Q

Alot of AMD users are seeing the exact same problem with the MG279Q - are Asus aware of this?

See these threads - Apparently it happens mostly when using the Sapphire R9 Fury Nitro - Sapphire denies any problems in their end.

I have that card and i have had i swapped only to see the issue again.

https://community.amd.com/thread/205764

I recorded a few videos of my monitor: see them here: https://www.dropbox.com/sc/pps8u0wao...RJtKzclH4Orkaa

I hope that someone from Asus will comment on this.

Thanks

Hi Morten,

Thank you for reporting this issue.

What happens most of the time is that service teams will test on their platform with similar specifications and may not be able to replicate the issue and isolate that as a single case or issue that occurs only with specific environments that has a conflict caused by hardware or software.

I have already highlighted this issue and I expect them to invest some time to look into this matter. I'll update everyone in this thread once I have information that is confirmed and that I can share.

Thanks,
Bahz

I am experiencing the same problem. Also with an MG279Q and a Sapphire R9 Fury Nitro.
It is highly frustrating and I don't want to downgrade to a GPU with less performance.
Hopefully this can be fixed without needing to send the monitor back.

I can provide photos and video if desired.

Hey all,

Same issue here. fury nitro with mg279q
I have attached a picture of the pixels going crazy in the middle.
To asus; I've been running the front porch timings reversed (49 - 8 instead of 8 - 49 horizontal - vertical) which gave me the issue less frequently.
Might be something you want to forward to your display team. Furthermore yesterday I experienced something weird that the monitor itself seemed to crash and was still showing the image of my desktop after my pc was off (albeit with black lines on top of it).
I'm looking forward to a solution.

Thanks,

Sander

Just to add to the previous people: I just got myself an MG279Q with also an R9 Fury Nitro, and also exactly the same issues with the latest drivers. For me toggling the monitor on and off generally fixes the issue, but of course this should not be required, especially with a monitor of this price range :).

In general I do have some issues also getting Freesync to function consistently. I don't want to hijack the topic, but I do wonder if it is related to each other.

Unfortunately there are no new updates regarding this yet, our team is still working with related vendors on a solution for this. I'll send another follow up with our display team to see if we're progressing on this issue. With the PG279Q we needed Nvidia's base firmware in order for us to work on our own firmware update so I assume it's the same case here where we need to wait for AMD to provide us with the same.

Hello all.



Just got a MG279Q a few days ago and using it with a Sapphire R9 Fury. Got the same blurry line down the middle as others have reported. Hoping there will be a fix for this otherwise its going back as I dont fancy down-grading GPU's.

I reckon this monitor has more firmware issues than just the one highlighted in this thread. Link (https://rog.asus.com/forum/showthread.php?88477-Asus-MG279Q-not-displaying-output-on-older-GPUs) to what I have seen with 3 differing MG279Q.

I picked up an MG279q last week to use with my r9 fury nitro. I too have the same line down the middle of the screen. I thought I could tolerate changing the resolution/refresh rate/turning monitor off and on as a fix, but it's only been a few days and is already driving me crazy. Especially since the issue and temporary fixes seem to occur and work intermittently. Have there been any updates on a solution?

What seems to work as workaround for me is: https://www.reddit.com/r/Amd/comments/558grc/a_fix_for_the_overlapping_image_in_the_middle_of/

Seems stupid lowering the refresh rate by 1Hz, but if it works, it can't be that stupid :P.

Thanks for confirming, so far it seems like some people were able to use this workaround solution to fix the problem, while there are still others that are reporting that the issue still happens but less frequently.

We're still looking into this issue but it seems to be a little different than the PG279Q issue with Nvidia.

I still have the issue while using the 143hz suggestion, however, it happens less frequently.

I also had the problem. The workaround (setting the monitor manually to 143hz) helped until now, though.

jershinator
11-20-2016, 02:45 PM
I have had the problem too. I'm running an R9 Fury Nitro as my primary card, and R9 Fury Tri-X as the secondary crossfire card. The 143 Hz workaround has not worked for me. In games where the monitor reconfigures/reconnects itself frequently like Assetto Corsa, it's most prevalent. I'm using the mini-DP to DP cable that came with monitor and occasionally get errors that the only available refresh rates are 60 and 90 Hz until i power cycle.

Has anyone had any luck with swapping cables?

This problem has been going on for over a year for me.

While I have the exact same issue as the thread author, I have a different card:

Sapphire Radeon R9 380X Nitro (aka Tonga)

When I enable FreeSync, my issue occurs at 90Hz, together with a blurry screen. With FreeSync enabled and 60Hz everything is fine. This seems to be completely OS independent.

When I disable FreeSync, I get plenty of error message from Windows Driver, but it seems to look OK. When I disable FreeSync on Linux, I only get massive flickering (and hence an un-usable screen).
Basically the same issues as described here: https://rog.asus.com/forum/showthread.php?74568-MG279Q-Displayport-link-failure-while-gaming


I already tried two identical monitors with the same issue (Respective SNs are in Bahz' inbox).

Can confirm I have this issue, alongside some other ones. Hopefully this give you guys more information on problems/potential problems with your monitor.

GPU: Sapphire Radeon Fury Nitro OC+

My issues are as follows:

1. Sleep to disconnect issue

Whenever I put my computer to sleep, or when the screen turns off after X seconds of inactivity, the computer treats the monitor as disconnected and resizes the windows. I have done research and apparently this is a displayport industry standard, but according to sources on a mg279q monitor review on newegg, an asus representative has stated that it is a known "error" on the monitor and requires a firmware fix. I have switched between multiple displayport 1.2 cables that are verified by the displayport website as certified.

Most notably, the resizing only occurs when I wake up the computer again, somehow when the monitor wakes up it disconnects itself and reconnects, resizing and moving the windows. I have tested this by connecting two monitors, and simply pressing the power button on the mg279q. The computer still recognizes that there are two monitors connected and retains the windows that were previously on the other monitor. However, if I press the power button, the screen will flash and the windows will fly to my secondary monitor, and then back to the mg279q which is now on and all the windows will have been resized.

2. Displayport link failure/refresh rate compatibility issue

Sometimes when the computer boots up, either from cold boot, sleep, or monitor wake up the monitor will experience a display port link failure or refresh rate compatibility issue and will be reset to 90hz, with the only options to change framerate to be 60/90hz in display settings..

3. Vertical line down the middle of the monitor

Sometimes when the computer boots up, either from cold boot, sleep, or monitor wake up the monitor will flash black and the screen elements will be off centre and blurry, with a vertical line down the middle of the screen. The vertical line down the middle of the screen occurs at 144hz. If set at 90hz, there is another bug that has a fuzzy line on the left hand side of the monitor.

Thank you for your time and attention. I hope this helps the investigation in this matter.

I had to return my darn great videocard because asus is taking 2years to get to fixed. Unfortunately this costs me money. Right now I am back to a 290x from sapphire without blurry line issues.

Now my z170 gaming aura motherboard (asus) doesn't recognize my nzxt water AIO vooler either.

A few years ago asus was top quality, doesn't feel like that anymore.*

I have experienced these exact same issues. There is a work around for the first however. Set your USB monitor ports to charge in standby and that should stop the screen from being resized.

As to the other issues I can't find a fix. They are more or less random in appearance and I think could be related to the video card/driver combined with the monitor. Given I believe this monitor would have to be sent in for a firmware update I am not expecting any real fix. Too bad as otherwise this is indeed a very good product.

I can confirm this started occurring after upgrading from 2xGigabyte 7970s to 2xSapphire Nitro R9 Furys. I always shutdown my computer once I'm done for the day but when I boot it up occasionally I'll notice the middle of my background is screwed up and text is blurry. To resolve the issue I open AMD drivers and toggle "Virtual Super Resolution" On then back Off, usually this makes the issues disappear but I have noticed it in GTA V making my crosshair circle look like two circles put together. I'll provide some examples next time this occurs as proof.

I fixed the issue using customs refresh rates with CRU. I added 143hz to the list which works perfectly with freesync. No more glitch, no more resolution mismatch in the OSD vs windows (2566 instead of 2560) and no more line in the middle since I've been running at 143hz.

From amd forum :

mkk 5 oct. 2016 13:47 (en réponse à bol)
Creating a "custom resolution" with 2560 x 1440 @ 143 Hz seems to have solved the problem in my case. At least I've not seen the artifact for two days (edit: four, considering it working), whereas I used to see it a couple of times a day before. When I did, turning the monitor off and on usually made it go away, if only to sometimes reappear after a game had been running.

I got myself a Sapphire R9 Fury Nitro on sale about a week ago and had that line right in the middle appear on my Asus MG279Q with Freesync mode turned on. First I tried going down to 120 Hz and there's a chance that doing so might have been enough in my case, but the responsiveness is still somewhat better at 144 Hz so I didn't want to give up. By chance I tried the custom resolutions option inside the Radeon Additional Settings panel.

I picked the CVT-Reduced Blanking for the timing standard, for no other reason than having good results with reduced blanking in other situations. If I understand it correctly it basically saves some signal bandwidth and is normally supported by reasonaly modern monitors, and can be quite useful at least when overclocking panels on a DVI connection.

I'm also using the CRU (Custom Resolution Utility) 1.2.6 to tweak the V range from 35 - 90 to 60 - 144, which moves this monitors Freesync range accordingly.

I've been watching this thread for a while hoping to see some kind of fix - whether it is a firmware update or a driver. I honestly can't believe ASUS doesn't seem to be doing anything about it. I've seen a little lip service - that's it. This is a pernicious quality control issue. The MG279Q is the only viable 1440p / 144hz / IPS monitor available. The Fury is the only GPU able to drive it and the line down the middle is an absolute joke. What a waste of time and money. If I wasn't into it already for more than a grand, I would have gone a different direction.

I will continue to monitor this and will continue to hope.

I have to agree. I'm super disappointed in ASUS for this. I'm in the same boat, cost wise as well. 2x Fury's and this monitor is like $1500 alone.

Myself, i use CRU to get 57-144.101Hz but like in 50% of times when i reboot/log out the line is back.

It's so frustrating. I spend alot of money on this 'new' setup and it doesn't work like it should.

Sure I use the modified drivers to achieve a better FreeSync range but when I see this happening as I stated before to resolve the issue I open AMD Radeon Settings and toggle "Virtual Super Resolution" On then back Off it takes 10 seconds.

Can you explain how the custom freesync tweek works? I know I've seen a thread about it somewhere but can't find it right now. Has it any downsides?

Was hoping for a downloadable fix, because now i have to buy a cheap 2nd hand monitor until the ASUS returns mine :/
But yeah, at least it's a fix :) Thanks Bahz!

Do we have to specifically ask for a firmwareversion as i'm kinda scared returning it and getting it back updated with a firmware version that doesn't contain the fix for our problem.

I opened a ticket, linked them to this thread, and gave the relevant info about my issue. I also included the PM I got from Bahz too. Hopefully turn around is quick

As long as the new panel doesn't suffer from horrible backlight bleed. I already had to return my first order of this monitor cos the backlight bleed was horrible. This new one is near perfect.

I saw that you had a few questions, regarding the first one if you can just download some software to update the firmware, no that can't be done because a special tool is required to update the firmware. You don't need to worry about the panel being changed as they'll just update the firmware and you'll get back the same monitor with the same panel.

While I have the exact same issue as the thread author, I have a different card:

Sapphire Radeon R9 380X Nitro (aka Tonga)

When I enable FreeSync, my issue occurs at 90Hz, together with a blurry screen. With FreeSync enabled and 60Hz everything is fine. This seems to be completely OS independent.

When I disable FreeSync, I get plenty of error message from Windows Driver, but it seems to look OK. When I disable FreeSync on Linux, I only get massive flickering (and hence an un-usable screen).
Basically the same issues as described here: https://rog.asus.com/forum/showthread.php?74568-MG279Q-Displayport-link-failure-while-gaming


I already tried two identical monitors with the same issue (Respective SNs are in Bahz' inbox).

Thanks for the additional information, I'll continue to push regarding this.

I got a PM from Bahz as annouced, followed the instructions and got a replacement monitor a few days later which resolved the issue with a duplicated line when FreeSync is enabled!

Unfortunately, disabling FreeSync in the menu of the monitor still causes massive flickering in Linux and causes a link failure in Windows (see image).

Nevertheless, thanks a lot for the effort, Bahz!

I just got my MG279Q back from RMA (using it with a Sapphire NITRO R9 Fury). Unfortunately, not only is the line still appearing (tested at 90hz and 144hz), but I have also lost the ability to get Freesync beyond 90hz using CRU. Freesync at 120hz, 143hz (to work around the line), or 144hz now causes massive display glitching when it wasn't before.

I'm really wishing I had stayed on the old firmware now since it was actually working better. Pretty disappointed.

InternetOwl
03-12-2017, 04:58 AM
Thanks for your report grum_feast. Pretty surprised to hear this honestly as can't figure why ASUS would go to the trouble and not have it fixed. Also a sad panda because with the hopes of this being fixed I picked up a Fury cheap. Ah well :(

grum_feast
03-12-2017, 07:39 PM
UPDATE:

I've got Freesync working at 143hz again with no glitching. That one was actually 100% my fault. When I was re-entering my settings into CRU I forgot that I had my range limit set to 57-143hz before and *not* 35-143hz. The glitching was happening whenever a game's FPS would drop below 57 as one would expect with a too big Freesync range.

So, to make everything clear, I am still definitely getting the line at 90hz and 144hz with all CRU settings cleared (completely stock settings). Everything else is working as before and 143hz is still acting as a workaround for the line for me.

Basically my monitor is acting exactly the same as before I RMAed it. I'm interested to see if others in this thread have better luck than me.

Also, just to help out anyone else in this thread who can't get the line to go away with CRU, I had to set my refresh rate to 142.856hz to fully get rid of it. Setting the mode to exactly 143hz doesn't seem to affect the line. I came to the working number simply by subtracting 1 from the stock setting.

Thanks a bunch for being a pioneer and reporting back. I've been wary of shipping mine back to get it updated; I too have had pretty good luck setting my max refresh rate to 142.908 in CRU. It's always a huge pain updating the gpu drivers and having to play around in CRU to get everything working again. Did you have any of the blurry text issues? That still causes me a lot of problems, particularly if I hook up a random laptop or surface to my monitor that I can't use CRU with; I was hoping that'd get resolved too; ditto with the line down the middle. Doesn't sound like sending it back for the update would worth it at this point if it's just to end up status quo.

Well I would thank grum_feast for the report again but I don't think ppl should be convinced they would get the same result. Hence why he wants others to post their results. I would but still waiting for my PM. Still ASUS would not go to the trouble without having made a new or 'fixed' firmware to update the monitors with to deal with the issue. Simply doesn't make business sense. Sometimes results vary for different reasons.

got a notification that my monitor was shipped back from asus after being in their hands for about 1 business day. I specifically requested a new panel and a firmware update, due to a dead pixel and backlight bleed issues. They never gave any statement of the work done to the monitor before sending it back, so I'm dubious I'm getting anything other than the exact same panel back from them... with or without a firmware update. I'll give an update when I receive the monitor.

Hope it works for you when you get it back. I would say a safe assumption is that only the firmware update was done as that is what this is about but who knows. In any case I am certain they did not ship it there and then ship it back without doing the firmware update. As I said before that would make no business sense at all in any context. Keep us updated.

My monitor came back today and as I expected, it was the same one I sent - so no hardware fixes, but I guess I can live with that. Also, I noticed some dust under the screen that I definitely never noticed in the last year and a half with this monitor. Don't know if this is new or old (or how it could even be new).

I've had the monitor set up for about 15 minutes so far and have been constantly power cycling it while connected to my pc at 144 Hz / 1440p and haven't had the vertical line appear yet. I'm crossing my fingers at this point but if it works long term, I'll consider myself satisfied.

If I don't post again, assume I'm good.

Something I never noticed before on stock settings. When I open up the OSD sometimes it reports that the monitor thinks it's running at 2568x1440 (when obviously it should be 2560). This seems independent of whether or not the line wants to show up but I still feel like it has to be related. Like maybe the wrong resolution gets negotiated and then you've got the monitor trying to scale it weirdly. A quick google search of 2568x1440 and mg279q turns up a few other people who have reported this happening too. So far I haven't seen it when I use CRU to set my custom refresh rate to get rid of the line.

Anyway, Bahz had Asus tech support contact me directly so if I make any progress with them I'll let everyone know.

Hey grum_feast. Never noticed before myself but indeed sometimes when I bring up the OSD it reports that the monitors running at 2568x1440 instead of 2560. On mine it does this whether the line in the middle is there or not. No idea if there is a connection though. Thought I'd add my two cents.

Best of luck with support. :)

Would you mind sharing and explaining your CRU setup? I attempted to apply refresh rates for 142 and 143 but it didn't seem to help.

Has anyone else got their monitor back and can report on the results?

grum_feast

Would you mind sharing and explaining your CRU setup? I attempted to apply refresh rates for 142 and 143 but it didn't seem to help.

No problem YiRz99. Here's step by step exactly what I did on mine since it was pretty baffling the first time I used it. I can also send you my saved CRU settings file if you want to PM me your e-mail.

First thing I do is nuke all the modes lower than 144 Hz since a lot of games have this weird habit of randomly starting in 60 Hz (not sure if this is a driver or a Windows problem or what). The second thing I do is move the 144 Hz mode from the extension blocks section into the main detailed resolutions section. If you don't do this after deleting all the lower refresh rates then Windows doesn't seem to recognize 2560x1440 as the "preferred" resolution anymore which causes some issues. Then I go into the 144 Hz mode and subtract 1 from whatever number the refresh rate was actually set to.

After this you can optionally try to overclock your Freesync range by changing the V rate range limits if you haven't already (no guarantee this will work on every monitor as it's not officially supported by Asus and all that). 57-143 Hz works great on mine (and if a game drops below 57 fps then the Low Framerate Compensator in the driver will kick in basically allowing Freesync to continue to work below its normal range).

Finally, after hitting OK a bunch of times, I run Restart.exe to get the driver to see the new modes.

Also you should know there was a bug in the AMD driver that was preventing custom monitor modes from being recognized. They fixed it just a few versions ago so make sure you're on the absolute latest driver.

Detailed steps
1. Select the one item that's listed under the "Extension blocks" section then click Edit underneath that. This will bring up your additional 2560x1440 modes that go beyond 90 Hz
2. Select the mode for 2560x1440 @ 143.855 Hz then click Edit underneath that
3. Click Copy at the top
4. Click Cancel
5. Select and delete all the 2560x1440 modes listed in that window
6. Click OK
7. Select and delete all the remaining 2560x1440 modes listed under detailed resolutions in the original window
8. Click Add underneath that section
9. Click Paste at the top
10. Change the refresh rate from 143.855 Hz to 142.855 Hz
11. Click OK
12. (Optionally) click Edit at the top next to your monitor name and under Range Limits change V rate to 57 - 143 Hz
13. Click OK until you've exited CRU
14. Click Restart.exe to reload the driver so it recognizes your custom settings

Been going through all the standard troubleshooting steps with tech support but not making much progress so far. Right now they're trying to say that my Fury card is defective since I don't get the line with my R9 280X over the same cable. Considering how many Furys this seems to be affecting I doubt there's anything wrong with mine in particular (though if AMD or Sapphire put out a firmware fix I'd happily install it).

Anyway when I get the time I'm going to try plugging my Fury into the DP on my old monitor just so I can let tech support know it's only the combination of the Fury and the MG279Q that's causing the problem.

I'll live with the 143hz workaround for now. Aside from the line issue this is still honestly the best monitor I've ever owned. If the problem ever gets resolved then I can actually start recommending it to other people.

I've read about multiple OC being used for a while without any issues. But as with everything, we can't tell quite really. It fixed all of my glitches, so I'm happy but still monitoring this. Since my last post I had the line come back, but because my CRU settings got overided. I'll read a bit more about this firmwire update offer.

Just saw this thread a few days ago.

I have the same issue with the same monitor, but with my Asus Direct CU2 OC R9 290x card. Sometimes when alt+tabbing or starting a game, it gets the strange line down the middle as well as on the left side.

Also, since the last 2 driver revisions from AMD, that is 17.4.x as well as 17.5.x Free Sync doesn't seem to work at all in several games. World of Warships, Mass Effect Andromeda.
FPS is rock solid steady 60-75-ish depending on the game. But both games exhibit lots of microstuttering, and when looking in the screen gui you can see the HZ changing beteween 89 -54 - 34, then back to 89 again. And I assume the change to 34 which is below the limit is what causing the stuttering. But it does that cycling about once every second or so. Turning Freesync off in the driver makes it smooth, but of course, with no v-sync on, lots of tearing.

Using no eyefinity, no crossfire, no profiles or anything. I do have a secondary monitor that is not vsync capable on the side, but never run anything except a browser on that window.

I have received back my MG279Q after RMA'ing for the firmware update. ASUS instead replaced the entire monitor when they shipped it back stating that there was a display port function error on my previous one. Luckily the screen seems to be fine on this new one however the line is still present at times. I assume that the new monitor would have the updated firmware so the fix did not work for me and my Fury. I appreciate the effort ASUS seems to be going to but the result is pretty poor.

In any case this is my result after RMA'ing the monitor.

*UPDATE* Turned the monitor on and there are green vertical lines running on the right side of the screen. My old one at least did not have that.

I don't know why it was replaced as the entire contact with ASUS Support was about the firmware update and nothing else. I had actually been glad they were not replacing the monitor as aside from the line issue the screen on my old one was fine.

I am currently talking to ASUS but they seem to have no idea. Between this and ppl saying the firmware update does nothing I do not understand the response on their part to this whole thing at all.
That's incredibly frustrating and why I'm hesitant to send mine in. I'm starting to think maybe I'll just have to live with using it at 143Hz.

Last time I talked to Asus tech support over e-mail they did want me to send my monitor back in for a second attempt at repairs (they didn't specify what the repairs would be). However, I too am definitely holding off on shipping it out a second time given other people's recent results.

I hear that grum_feast. Still that I have heard I am the only one to have my monitor replaced. I still think ASUS seems to really be trying to address this problem but the chain to the support centers seems to be broken. I wouldn't assume you would get my result and there has been at least one positive post for the issue and monitor being fixed in this thread.

But yes, IT IS incredibly frustrating.

Well I ended up selling both my Sapphire AMD R9 Fury's and jumped ship to a Gigabyte NVIDIA GTX 1080 Ti so good luck to everyone who is still working to get this resolved but the 143Hz did work well for me.

Okay. This will sound rude, but since I have just received my second reply from ASUS telling me to 'reset the monitor' in the OSD along with a helpful diagram of a VGA end explaining I should look for 'bent pins', here goes. First, I DON'T KNOW if the firmware was updated. I assume it was not on mine but I don't know. It was RMA'd and sent away for that explicit and only reason. Instead it was replaced with a new monitor. A busted one that STILL has the same line issue on top of it. I don't know why it was replaced. I only know I got screwed somewhere between the support and the service center.

I know you are trying to help Bahz, and imo you have done a pretty good job here. ASUS support was great too. But the end result was basically a joke on me and ASUS. By the bye, if I hadn't gone through with the firmware update, I wouldn't have sent my monitor away and thus would still have my original working screen. Sure it would show the middle line but it wouldn't have faint green and red lines on the entire right side. :mad:

Could you please PM again with the product serial number of your current unit and also the previous RMA#? I will further escalate this case for you as you deserve no less than a perfectly working monitor. Sorry I didn't further follow up with you since you received the replacement.

Thanks for confirming, if I remember correctly since the firmware was updated on your monitor. Using the 143Hz solution has fixed the problem for you right? For some even the 143Hz solution isn't working. I've reported the Fury Nitro issue to our display team but there's no update yet, I will further follow up on this.

I received a new monitor back from ASUS and can report that everything is now fine. The new unit is great but just as important is the fact that the line issue is now gone. I have tested it for several days using my Sapphire Fury Nitro and the line no longer appears at all. One thing is that I have also been the checking the reported resolution and it is now also always correct where before in the OSD is was usually just slightly off as several of us noticed.

So thank you to Bahz and to the ASUS team. A few false starts but they got it done. :D

Sigh... well I got the monitor back and so far the strange line in the middle hasn't shown up. However, I now have an entire column of dead pixels stuck on red that are about 1/3rd from the left side. I tried resetting CRU and updating the drivers but I'm pretty sure this is a physical problem.

I'm guessing now I need an entirely new panel...

Hoping for the best, I'm sure you won't need to send it in again as they're going to quadruple check this time before they sending it back. We do apologize for the inconvenience caused.

I'm ok with the additional wait since shipping was paid for and thanks for the escalation Bahz.

A bit more details on what it was doing before I sent it back again btw... With the CRU settings reset and the refresh set to 144hz I probably power cycled it 30+ times without the original blurry line showing up. Before it came up maybe 1 in 5 times so I think the new firmware fix really worked this time. To test the solid red line I plugged the monitor into my Chromebook over HDMI and it was still there so it definitely seems to be dead pixels and not something else.

At least this new issue won't be as tricky for the service center to troubleshoot.

Alright, got everything back from Asus today so here's my report.

They went ahead and sent me a brand new MG279Q. No dead pixels that I can see and the backlight has less halo than the one I had before so zero complaints there. I plugged it in through DP, made sure all my custom CRU settings were cleared, and set the display to 2560x1440 @ 144hz. After power cycling the monitor over 20 times the strange line has *not* shown up.

Unless by some miracle it glitches out later I'm going to say everything is looking good. Thanks Asus and Bahz.

Hey, can you provide an update on this? Is the issue cleared?


@Bahz, I would like to have my monitor shipped in for repair too. What steps do I need to take?

Yes, through multiple reports of users who sent it back for the firmware update, this issue now resolved. If you confirmed that you do have this scan line issue then please contact local customer service to arrange to have monitor sent back for RMA. If you encounter any issues with the local customer service, please send me a private message with the product serial number, RMA#, and Case ID# and I can follow up on this for you.

I sent my monitor in last Wednesday and got it back the following Wednesday. The whole process took one week. The scan line issue is gone. Bahz was great. Thank you very much for helping get this issue resolved. The panel looks great. Running at 144hz with no issues. Finally!!

I found this thread yesterday and have been wondering for 2 years what was wrong with my computer/setup. I spent thousands replacing parts and building multiple computers to figure out the issue and for some reason didn't suspect the monitor. I went and bought a PG279Q (since I have another computer with an Nvidia card) and of course the issues I've been having are completely gone.

My symptoms:
- Horizontal Scanline that goes top to bottom is extremely apparent
- Screen generally looks blurry
- Colors are dim when the issues are occurring
- Vertical line down the middle of my screen before installing drivers, or permanently there on the BIOS/startup logos
- Caused input lag in all games as well as slight input lag on the desktop
- Generally looks choppy and doesn't look like a true 144hz

I'm not sure where I should go from here but if possible I would like to RMA the monitor. An Asus employee told me to 'hard reboot' the monitor so...I'm hoping it doesn't get shrugged off like that. Is there an Asus employee that knows about this issue that can help me out?
