[Ls9L]

so i dont really know how to explain this well but on a xbox one s you can make the operating system like the home screen and youtube netflix etc 4k res but when you go to a game its in 1080p full screen so i was wondering is there a way to make my windows 4k res like chrome youtube the desktop and everything 4k but when i start up a game can i make it 1080p fullscreen without having to change my resolution back and forth when i want to watch 4k netflix and gaming because when i do make it 4k and try to put a game in 1080p its not full screen its super tiny

So your desktop is 4k, you want to game in 1080p. Assuming you set the game to 1080p full screen it should be ok. You might also check the GPU driver settings that it is doing the upscale, or if the GPU isn't doing it, it would need the monitor to do it.

Set the game to fullscreen and 1080p?

If you have nvidia GPU, in the driver there are several options like maintain aspect ratio stretch, or integer scaling (on newer GPUs), or "let display handle it". Try those. Maybe also check if your monitor has any kind of scaling options. It needs to be done somewhere. Similar probably applies to AMD but I don't use them nearly as much so have no idea where or what they're called.

 

I'd guess it is currently mapping 1080p 1:1 pixel wise to 4k hence it looking small.

You just need to select full screen in the game options.
