I don't see much advantage to someday putting a 4K set in place of the 90". Most of the room would be beyond the ability of a human eye to discern all the extra pixels. If there were 4 45" TVs in place of the 90", and you watched from the same distance, I don't think you'd see all 8 million of those pixels either. A 22:9 4K set in the 125" range (if it was short enough vertically to fit) might be an improvement. And yes, I would love to have one at my house right now, LOL!
