How does 720p look on this 4k set
My cable company/box has 720p HD channels, don't think they will be upgrading soon. I know this set like other 4k sets will upscale 720, 480, 1080, etc to quasi 4K to fill screen, but from what I had read about 4k TV's in general, this up conversion process makes the picture quality worse, vs watching 720 on a 1080 set. Any thoughts/opinions on how the non 4K content looks on this set, or others.??
