Hello everyone! I heard that you can't experience the FULL advantage of 1080p if the picture is too small or if you sit too far away from the screen. No matter what, I will be sitting approximately 13 feet (156 inches) away from the screen due to room limitations... At what screen size would you START to experience the FULL advantage of 1080p at this distance? Is there some type of formula or something that can be used to determine this? Thank you so much!
