Hello, my question:
Why can I do if my max selectable resolution is 1650X950( my tv and my laptop resolutin is 4K) ?
(Asus Zenbook duo, sony 4k oled, wifi connection)
Can you try adding a custom resolution in your spacedesk Viewer?
note: In the custom resolution list, it will only show the resolution not bigger than your device’s native screen resolution.
go to settings > resolution > Make sure that custom resolution is checked > choose custom resolution > From there, you can select your desired resolution or try adding it manually by typing your resolution.
