I am sorry but once again we have someone spouting there own opinion on this subject as fact.

I am not actually saying you can see a difference on a 46" at 10 foot, you probably cannot but I am simply stating that I would like to know.
Not opinions actual testing.
Lots of science on the resolution that the eye can distinguish at 20/20. 4K on 46 inch at 10 ft is not it.
