Non-native resolution scaling problem

[Shailab]

I have a 4K screen laptop. When the resolution is set to 4k every thing looks crisp and clear but when I set the resolution to 1080p or 2048 x 1152 everything looks blurry. Can't I fix this? I have tried different methods but one of them helped.

No, all non-native resolutions have interpolation applied to them on almost all displays, which will make it blurry.

That's how LCD/LED monitors work I am afraid.

If you run them at any resolution other than the native, they'll look bad. To what extent, depends on the panel.

That's one thing I miss about CRTs, was how well they scaled different resolutions.

 

Otoh, they had flicker, especially at lower refresh rates like 60-70 Hz, I'm guessing because of a super fast pixel response time.  I've even detected flicker as high as like 75 or maybe 85 Hz in certain circumstances, like a large display in my peripheral vision, I think.

There may have been a near-end-of-life fluorescent light in the same room in the 85 Hz situation, I don't remember now.  I definitely could see 75 Hz flicker.
