Hello,
I hope you can help me to solve my problem, I recently replace my GPU (2080 to a 7800xt).
I used to be able to use my TV as a second screen, but since I've been using the 7800xt, my resolution is stuck at 640x480.

I installed the drivers for my GPU with the adrenaline app.
I've already run Windows update...
I did some research and discovered that my TV wasn't fully recognized:

If you have any questions or solutions, please do not hesitate to contact me.
