Thanks for the report.
Please disconnect your second display. Does the issue occur only with the Asus Freesync monitor connected ?
How is the second monitor connected to the graphics card ?
Can you try pressing Alt + Enter to navigate through full screen - windowed mode to see if that resolves the issue ?
Hi Ray, thanks for replying.
Issue occurs when only the Asus monitor is connected as well. All the OSD functions are not effected by the artifacts, just what the game is drawing.
Second monitor is connected via HDMI, having it connected or not has no effect on the issue (although I noticed massively increased alt-tab times when not connected with a second display).
Attempting more debugging, I tried to set the refresh rate to 144Hz in Windows and disable Freesync. Any Unreal Engine games would reset the refresh rate to 90Hz upon launching. Windows would then spam me DisplayLink errors, and upon checking the refresh rate in Windows, I had lost all refresh rates above 90Hz. See: http://i.imgur.com/luWrCUl.jpg. I would have to restart the display driver to get the driver to pick up the correct refresh rates again. Normal operation : http://i.imgur.com/aW6uUJr.jpg.
Unreal Engine 4, when set to Fullscreen, is set to grab the Windows operating resolution and use that (bUseDesktopResolutionForFullscreen=True). I'm not sure why it's pushing me back to 90Hz (even when Freesync is disabled) whenever I launch a game using the engine. No other games do this, just Unreal Engine 4 powered ones.
Due to the above issue, I was unable to see if the problem happens above 90Hz. However, setting the refresh rate to 60Hz equalled absolutely no problems whatsoever.
Windowed mode solves the problem, but what with having a Freesync monitor and Freesync only working in fullscreen mode, it sort of defeats the purpose.
Hopefully this extra info helps.
Someone over at Reddit posted some more info regarding this problem, and it's happening on Linux too (which is very interesting):
Two weeks and no reply, not sure what to do about this...
Got lots of reports from others now confirming it seems to be an issue with just Hawaii cards (possible BIOS or hardware issue?). Would appreciate a reply please.
Sorry, this slipped through the cracks. Let me check with driver engineering if they have any information on this.
I'm also experiencing the same issue (on same screen) and freesync off but on my BIOS and Linux and only when the system tries to be at 144Hz. No problem at 60Hz.. I have not been able to test games under UE4.
Issue only on 290X. I've test two cards (Ref cooler + TRIX).
Also tested a fury : No issue.
Any updates? It's been another two weeks and nothing has changed with the 16.3 drivers.
Any further update after a month has passed? Been almost two since the original post - still an issue for people with Hawaii cards.
We've been investigating.
As of now since it affects the BIOS screen as well as Linux (with no Freesync support) it appears to be that this device is more sensitive to a specific display timing.
We are not ruling out a driver or VBIOS issue as yet, but are conducting further testing.
That timing issue might explain why the MG279Q is particularly concerned under different conditions by this line to the left.
Thank you for keeping us informed of your tests
Any news of these tests one another month after ?
It is always a timing issue? Owners of mg279q really expect a new vbios (which would correct the problem in any condition)
Any updates regarding this?
Thanks for the info so far.
Please AMD, please give us progress of these tests
Ray, it's been 4 months since I reported this problem, have you made any headway with it? Had no correspondence so far since March!
Sometimes same here (290X Sapphire) with MG279Q too.The image is a little blured , and too at right... It's not a freesync issue. Perhaps bad monitor detection ?
I'm having this issue as well, although I have an R9 380. It seems to always happen in 90 and 144 hz, but on 120 hz its more occasional. No problems with 60 hz.
It's not easy to find these kind of threads on Google...
I'm gonna chime in and say I have the same problem. Also this problem: Freesync refresh rate drop/desync , which might be related.
Users hadn't had luck with getting a new monitor. Today ASUS replied within 24h saying I may get another replacement (I had another problem with the monitor a couple of months ago).
Videos of the problem:
Up until recently Vapor-X R9 290. Now a R9 Fury Nitro
i5 2500k and 16 gigs of RAM but that shouldn't be important
AMD, users have been begging for answers on these issues for what seems to be half of an eternity. Why are you treating your customers this way?
Also, not cool, ray_m. Just going dark like that. Please respond to questions in a more timely manner.
Thank you and KR
I've been having a blurry vertical line on the same monitor MG279Q for over a month now. It happened when I upgraded my old Radeon HD 6950 to a Sapphire NITRO Radeon R9 FURY 4G HBM with Back Plate. The Radeon HD 6950 had no problems with this monitor but the R9 fury in combination with this monitor is a disaster. The R9 fury card works perfectly well on other monitors with freesync. Only when the monitor is connected to the MG279Q I get a blurry vertical line in the middle of the screen. Asus has send me 3 different MG279Q monitors and they all have the exact same problem. I've had the videocard tested aswell and there was nothing wrong with it. Asus wont even ackknowledge to me that they can't fix it, they keep blaming the videocard. And the videocard company in turn blames Asus. Meanwhile i'm stuck with a broken monitor for 600 bucks.
The vertical line in the middle of the screen doesnt always happen. Mostly it happens when coming back from sleep mode or when the display is turned of or when you start a game or when you quit a game. It also happens when turning freesync on or off. (Yes when freesync is turned off it still happens). And it happens when changing you're refreshtime.
My question to asus is are you ever going to fix this problem. Give a timeframe on when you're gonna fix it. Don't let your customers in the dark. This problem has been around since august 2015 if you google it. 1 year later and no progress on the issue is made? This leads me to believe you're never going to fix it.
Any response from asus is better than no response at this point.
Images of the issue:
Example 1: [IMG]http://i67.tinypic.com/2w5vf2t.jpg[/IMG]
Clearly a blurry vertical line running through the middle of the face.
Example 2: [IMG]http://i66.tinypic.com/346rkee.jpg[/IMG]
Clearly a blurry vertical line and in the middle of the screen you see all the letters cut in half.
When i said Asus needs to come with a fix I actually meant AMD.

Have you tried a better DisplayPort cable?
If you are getting DisplayPort Link warnings that usually indicative of cable issues.
