disable 4k upscaling

I have a pc with a Radeon R9 380 hooked to a 4k Samsung UE48JU6550 Screen. I use of course native resolution of 3840x2160.

Windows looks good, everything is clear and sharp. But when I look at for example full hd videos, they are blurry. The reason for that seems to be automatic upscaling. It looks like anti aliasing in older video games. Sharp egdes are blurred. This occurs only on that part of the screen, where the lower resolution content is shown, so I figured the graphics card is responsible for this.

Is there a way, that one can change the way, upscaling is handled? I would like to forbid my gpu to blurr my content. Instead of computing a new pixel colour from the surrounding pixel values of the video, I would like my gpu to just take the colour of the nearest pixel of the content, so that edges won't be blurred. I cannot find anything like this whatsoever.


Is this even possible?
