I'm using a 4K TV as my display, which has its own built-in upscaling that doesn't do a great job. I'm trying to have some games at 1440p get upscaled to 4K. However, when I enable GPU scaling in the Radeon software settings, it still outputs at 1440p. When I set the in-game resolution to something slightly higher than 1440p, then it gets upscaled to 4K. But when the in-game resolution is 1440p, the video gets output as 1440p, and the TV has to do its own scaling.
I'm guessing that the TV is somehow "reporting" that it can handle 1440p and 4K, and that's why the card doesn't upscale 1440p to 4k.
Is there some setting in the Radeon software to make it always upscale to 4K, even if the display says it can do 1440p?
Card: Radeon 5700 XT
Software version: 20.5.1
