the closer you get, you need that higher resolution 4k content
it will probably be some time yet before i can regularly enjoy 4k on the new LG 77" given how little daily content exists out there
I actually had to get something like 4 feet to the 77" before I started to see the compression/upsampling artifact off of Netflix (or maybe it was a DVD). Using a 4k blue-ray I think I started to notice the artifact just a bit before I started seeing the pixels at about 2'(?). BTW my eyesight is less then great so ... your mileage my vary.
In any case ... for me, the compression/upsampling artifacts is more noticeable and annoying than the pixels.
