How wide is a 22 inch tv?
Televisions are measured by taking the diagonal size of the picture. On new LCD and Plasma displays, the measurement is the size of the visible picture, which is the entire LCD panel. On older CRT (tube) televisions, most sets were rated in size based upon the size of the entire Cathode Ray Tube. Usually an inch or so of tube was hidden behind the bezel (the plastic border that surrounds the tube), so the measurement never reflected the actual visible picture size. Some countries passed laws to outlaw this sales practice.
