I use English translation, sorry
Question:
The original resolution is 2560x1600, the system is win11, and the graphics card RX6750XT
I tried HDMI cable direct connection.
Attempted to switch from DP to HDMI.
Attempted to overclock the display screen.
Attempted to reinstall the graphics card driver.
Anyway, the resolution can only be locked at 1680x1050.
But I used another computer graphics card, GTX1050ti, without any problems.
The display manufacturer is ARZOPA.
I suspect it is a compatibility problem. I hope AMD graphics department can see it and fix it in the next two weeks.
Thank you very much for your help.
If you need to provide information, I will provide it.
