Native 4K or Checkerboard "uprendered" 4k

How can it look blurry? I understand it's blurry if the monitor upscales from 1080p to 4K (and uses an upscaling technique similar to those you linked to), but can't you prevent it from upscaling so that it remains the original sharp 1080p image?

Those pics don't work, except for one.

It's basically this :

I have no influence of what the monitor does with the image. I just imagine that the frame buffer in the monitor is always 4k whatever the size of the source frame is and it fills due to interpolation the missing dots.

Damn it! Because a new plan I came up with recently was to get a 4K monitor next instead of a 3440x1440 monitor, so that I can play all my older games in 1080p without any scaling problems. Since 1080p is 1/4 of 4k in amount of pixels it should show up perfectly on a 4K screen and look "native" if every original pixel is represented by 4.

But from your experience the damn interpolation apparently interpolates and thereby softens and blurs the image automatically!

Damn it, what am I gonna do now?

Decisions.
