PC Graphics

[sadpanda]

This just happened out of the blue. 4k TCL TV connected to rx 6800 graphics card. Said "HDMI disconnected" during game. Restarted PC, it starts in 1440p and can't change resolution (greyed out).

My graphics drivers were destroyed. Settings were missing in AMD software. The screen looked like crap. HDR was unavailable. I reinstalled AMD software and now everything is working correctly for now. 

Please, does anyone know why this would happen? Is there a way to narrow down if my graphics card needs to be returned?

It could have been your AMD driver was corrupted and after you installed it again it fixed the issues or possibly a power issue from the PSU or Windows corruption or Windows Update installed a different AMD driver than the one your install.

Keep using the PC and see if the issue comes back again. If it works normally for a week or longer using your PC than the GPU card should be okay.

Run this simple line command in a elevated Command  Prompt/Powershell to check your Windows OS installation:

SFC /scannow

To check your GPU card to make sure it isn't going bad I would download and run OCCT GPU, CPU, & PSU tests. This will stress out the GPU card and if it is going bad it either will stop the OCCT stress test or your PC will crash or shut down.

Also run the CPU and especially the PSU Test which runs both the CPU and GPU Stress test at the same time putting maximum stress on the PSU.

During all the OCCT tests keep a close eye on Temperatures, Fan Speeds, & PSU Outputs (3.3/5.0/12 Vdc).

Can you upload a image of GPU-Z to see if the AMD Driver is working correctly and it showing the correct data for your GPU card?

Thank you for the help my friend, I appreciate it. When the display crashed before it was under very little load, but the stress test you recommended made it crash too. Had to reinstall AMD software again.

I tried resetting the graphics card and now the stress test isn't making it crash so I don't know, maybe it was a loose power cord. Anyway here's a GPUz picture, is this what you were talking about?

Thanks for the update.

Yes GPU-Z seems to indicate the AMD Driver is installed correctly.

As you noticed all the appropriate boxes at the bottom of GPU-Z for a AMD GPU card are correctly check marked indicating those APIs are enabled and working.  Plus it is showing all the data correctly for your GPU card.

I see you have AMD SMART enabled on the GPU card also.

Make sure you have Windows  Update for Driver disabled so Windows won't install an incompatible AMD Driver after you install the current AMD driver: elevenforum- enable-or-disable-include-drivers-with-windows-updates-in-windows-11.2232/
