NTSC stated that screen size V. viewing distance should be calculated by diagonal size times 7 feet to eliminate the scan lines. I often hear people complain that their TV looks grainy, they are simply sitting too close. Don't let ego or oneupmanship play a role in your TV. Leave that to your true audio dealings, you'll be happier!
How big is too big?
There has to be some sort of ratio of room size to screen size. I was thinking about getting an 84" screen but realized that it would be WAY TO BIG for the room after drawing it on the wall with chalk. Have any of you put too large of a TV in a too small room, or the other way around?
