All 1080P Will look gritty on A 4KTV. What you can do is turn on the digital noise filters and reality creation off to smooth it out. Or better yet if you have an xbox s or x, you can run your cables through that and it will upscale to 4k n look way better. Once you go 4K it's really hard to go back to 1080P. 4k, wide color gamut and hdr just cant be beat.
