Question Should I upgrade my Graphics Card so I could enable Integer scaling ?

[SLR2009]

Does enabling Integer scaling improve picture quality for 1080p videos on my 4K TV or is that only for gaming?

Is there some problem with current picture quality?

If not, then just leave well enough alone.

If there is some problem or specific concern then update your post to include full system hardware specs and OS information.

Include make and model 4K TV information and connectivity as well.
