Rx6750 xt black screen

Hello, i recently purchased rx6750xt gpu, and i am having issues with it. In my setup i am using two monitors:

Main monitor - LG Electronics 27GN800-B 68.5 cm (27 Inch) Ultragear QHD Gaming Monitor (AMD FreeSync, 144 Hz, 1ms GtG), Black, 27 Inches

Secondary monitor- Pavilion 22xi 1920 x 1080 @ 60 Hz

850W power supply, my CPU is ryzen 7 3800x

Motherboard - asrock b450m pro4 r2.0

At random times my main monitor goes black. After 2 min it fixes itself and i have noticed that the gpu drivers disable themselves. I get this message in adrenalin software

* default radeon wattman settings have been restored due to an unexpected system failure * 

After that i need to restart my pc so the drivers can be activated again or manually activate the gpu in device maneger

I have tryed DDU but no change. I also tryed installing old drivers but the problem is still there. If anyone have any suggestions please post them.

Good day! The reasons for this behavior can be many. But first, what windows do you have? 10 or 11? And what is the value of Tdr_Recovery in the registry at hkey_local_machine\system\CurrentControlSet\Control\GraphicsDrivers\TdrWatch

Hello, when the problem started occurring i was on win 10 , after that i installed win 11 but the problem is still there. The value of TDR_RECOVERY is 1.


Set TDR_RECOVERY to 10 decimal, restart your PC and check if the problem is gone
