Hi my Full HD Monitor downscales 4K to Full HD on consoles but not on PC

Hi there,

 

bought a new LG 27GL63T-B. On console i can set the resolution to 4K and the Monitor downscales it and shows it in Full HD. I know that it must be the monitor because on my old Asus Full HD i cant set the resolution to 4K on the consoles. But on PC i cant set the resolution to 4K with the LG. Can someone tell me why? Thanks!

My guess is your cable can't carry a 4K60 signal and is probably limited to 4K30, so it steps down to 1080p.

it can. i found a soulution. The AMD driver blocked unsupported resolutions. So i used Custom Resolution Utility to set a 4K Resolution. Now it works. I dont know if amd doesnt know that there are downscaling monitors on the market or why 4K is blocked but it workes now XD

What's the point tho?

downscaled pictures look better than native resolution. Did you ever watched a 4k video on an Full HD Smartphone screen? An higher than Full HD resolution image downsampled to Full HD look better than native Full HD. An higher than 4K resolution image downsampled to 4k look better than native 4k

Yes, but you have nothing to gain from outputting 4K and have the monitor downscale compared to rendering at 200% scaling and outputting 1080P, the GPU actually likely downscales better than the monitor does.

But doesnt it affect the performance of the GPU to render and scale at the same time instead of just render the image in 4K?

No, shouldn't. Scaling is like nothing for a GPU.
