4k vs 1080p...stupid question, or am I just too old!
Ok! I've looked at several sets now on display at a few HDTV sales outlets, and maybe I'm just too old, but is there a threshold that exists where the human eye is no longer capable of perceiving any more DPI?
BTW: I'm 47 and wear reading glasses, but i also have 20x15 vision.
Here's why I ask.:
When I look at sets less than 50 inches, I don't see any difference between 4k and 1080p.
When I look at sets over 60 inches, from around 8 feet away, I can see a good bit of difference between 4k and 1080p.
When I look at these sets from greater than 10 feet away, I can no longer see any difference, and with a 70 inch set, you'll need to be at least that far away to view the whole screen.
