I think I get what the OP meant.
You have two windows, of equal size, side by side, and you can see the trees swaying in the wind outside. You are stood 5 feet from the windows.
Except one window is a TV showing a camera display of outside, the other is an actual window. You can't tell the difference without moving closer. What resolution would the TV need to be?
