AMD Custom GPU 0405 (Steam Deck) is not yet supported by AMD Software making display resolutions unavailable for Windows 10/11.
Already tried downloading AMD Auto Detect but doesn't proceed with installation.
Is there a way around this because I couldn't play games on full screen display?
Contact steam deck support for any issues.
Valve does not support Windows in the steamdeck.. they deny searching for any problem
you can try to install AMD Adrenalin software from driver version 2.9.1 with the latest Valve's driver.
