A 70'' TV– You should sit between 9 and 14.5 feet away from the screen. A 75'' TV– You should sit between 9.5 and 15.5 feet away from the screen.
Your question is vague. If by "distance" you mean the diagonal length then on a 46" TV the diagonal length is 45.9". If you mean how far should you sit from a 46" TV then around 7 to 8 feet.
One mile
Yes as far back as the 1950s
7ft
You can lay a lcd tv down on its back as far as for 8 hours not to sure for that long
Popular Science Sep. 1980 shows a 45 inch television set. This is the largest size my research has showed so far.
One inch.
A wireless game controller means you can sit as far away from the TV as you like. Put batteries in the back of the controller and push and hold the center button, a lite should appear. That means its on.
.0011 1/2 of an inch
As far as I know they do not make and 80 inch television with a built in DVD player at this time. Considering the amount of money that you would spend to purchase an 80 inch television I wouldn't recommend a combo anyway as there are just more functioning parts that have the possibility of breaking down. If the DVD player quit working you would have to replace the television instead of just the DVD player itself.
Many people make the mistake of buying a big screen TV without considering the most important factor in the buying decision. How far away from the screen will you be sitting when you watch your favorite programs? Obviously, your budget and the dimensions of your room will limit the size of the flat screen TV you select. As a general rule, the bigger the room and the greater the viewing distance you have, the bigger the screen should be. Where a 32 inch flat screen delivers a picture just as sharp as a 60 inch model, it would not be as easy to see if you were viewing it from 20 feet away as opposed to 10 feet or less.
It doesnt really matter how far your speakers are from the tower.
