Hi i've read a similar rx 6600 xt problems like mine here but i wonder why amd devs or someone do not resolve them or respond to ppl who have spend some hundrends of euros to buy amd's gpus.May be are the drivers may be not at least give us a solution plz.
To my problem now...
Recently i upgrade my pc buying a gpu ''msi mech x2 8g oc rx 6600xt'' and i face a weird problem.
When i turn on my pc and my screen is turned off from power button the vga led on mobo is on,thats an issue.When the screen is stand by and turn on the pc again the vga led is off.Also i noticed that sometimes the screen flashes for a fractions of a second also sometimes when i go to fullscreen black screen appears and thats it no other problems found so i try these things below.
Use DDU and Revo for deleting old drivers of Nvidia.Also use the same apps for deleting AMD adrenaline and install it again.
Pull out gpu and back again over twice.
Change psu from 520w to 750w
Update mobo bios,graphics card drivers and screen drivers.
Disable upls from registry.
Change with vesa certified dp cable.
Try the cable in all dp ports.
Try the dp from my 2 different older graphics cards (rx 560 oc saphire) and (gtx 1660 oc gigabyte) with no issues.The dp version in all gpus are 1.4 msi included,screen has 1.2 but this is not a problem.
Try hdmi cable on msi gpu with no issues.
Contact with AOC for replacing the screen,the new screen arrived but i have the same issue so i kept my first one.The screen is also new.
Plz can u help me on that, is there something else i can do?
There is a short video on YT with my issue but i cant link it if u want.
Sorry for my english.
