@AMD_Vik Apologies for the info dump, but I figure this will get forwarded on somewhere so it's best to be as complete as possible...?
Also, I can't attach an image so I have linked one that shows the outputs on the card. So we are on the same page, I refer to the ports from left to right as:
DP-1, DP-2, HDMI-1, HDMI-2

Primary display (windows monitor 1): Dell/Alienware AW3420DW (Running 3440x1440 @120Hz) connected to DP-1 (see pic)
secondary display (windows monitor 3): BenQ XL2410T (running 1920x1080 @60Hz) connected to
APU/Integrated/onboard HDMI (monitor only supports 120Hz over DVI and connecting to the GPU may reduce bandwidth on other outputs)

My primary monitor has a refresh rate output onscreen that I can see in realtime.
Summary of issues/symptoms:
======================
1. "visual glitches"
This is the main issue that I can't live with.
The glitches can be different symptoms but I feel like they are the same root cause. the seem to start under the same scenario but I never know which of the symptoms will manifest.
a.) display pauses momentarily. This tends to follow 1 of 2 possible time cycles. either: every 2mins 20 seconds the screen will pause (maybe a couple of times) for a period of about 2 seconds. Also, the screen might go completely black as part of the glitch. Or the frequency is every few seconds (maybe 3 or 4 seconds) for a period of something like 1 second or maybe less. During this time, audio is not effected and the mouse sometimes resets to the center of the primary monitor. Although I note, Windows does seem to track the mouse movement while glitching so that the mouse may appear frozen but jump to the current location once "free". This glitch effects both main screens simultaneously.
b.) VR display errors
Tied to the glitching issue, as in it happens under the same circumstances, but has a very different symptom...The symptom here is that launching steamVR starts fine but withing a short time the performance graph becomes full of purple (display error) occurrences - not just an odd spike.
This makes the framerate drop to sub 10FPS. It can happen just inside the "home space" after launching. I haven't left it more than 30 seconds to see if it corrects itself.
c.) Primary display blanks out and Windows hangs.
This is a weird one that I've seen a couple of times in the last few days... I've not seen it happen while I am at the PC, it is only when I come back to it after a prolonged period. No windows commands work and the PC needs to be reset.
Gut feeling is that it is another symptom of the problem being triggered. i.e. if the problem isn't corrected, after some time this symptom may happen.
2. VRR or Freesync inconsistency
I've noted that currently, with VRR enabled on the primary monitor (which supports it) fullscreen youtube videos are locked at 120Hz whereas a few days ago they would fluctuate depending on the content.
3. trouble setting custom resolutions
Maybe this is not an issue, but when setting a custom resolution for the projector the default pixel clock that the projector supports at 4k appears as invalid. (red !)
So using Adrenalin, if I look at the display specs it shows me a pixel clock of 1188000. When I go to create a resolution, it defaults to that value but shows it as invalid. weird right?
Only way I can create a resolution is to change the timing standard to something that lowers the pixel clock.
Having said that, when I go in there today I notice something that could be interesting...
- it is showing the invalid (red !) on pixel clock for 2 previously created custom resolutions.
-The pixel format and colour depth are less than they were a week ago! pretty sure it used to be 10Bit ycbcr 4:4:4. Now it is 8Bit 4:2:0
I'm wondering if there is some relationship between the custom resolution and the glitches...?
Controlling the Glitch issue: (usecase/workflow)
==================================
When I start the PC I get 2 screens wake from standby and funtion normally. this is fine, and I can even use VR connected to DP-2 with no issues.
There are times when I choose to use the projector and turn it on only when required. This also works fine (although I wonder about the custom resolution as mentioned above)
But as soon as I power off the projector after I have finished using it, the problem starts. Any of the glitch symptoms are likely to happen from this point.
If I turn the projector back on, the symptoms go away.... until I turn it off again!
Sometimes restarting the PC will put things back to a normal state of things working fine without the projector running, but not always.
The most consistant "fix" has been to shutdown the PC for a long period (a day, or overnight). It's hard to say how long is needed to be sure it will fix itself.
Please let me know if there is other detail required or anything I should try.
