So, you bought a 17 "monitor only to find that his screen is 15.75" measured diagonally. "This can not be right," you say: "I expected the screen to 17". Well, unfortunately, it's normal for CRT monitor. Although the CRT monitor may be 17 inches, the actual "Diagonal" may be less than 16 inches. This is because the screen does not use the entire tube for projecting images.

Do not use the full range of cathode ray tube monitor, the screen can display sharp edges and corners that do not fade or bend the sides of the screen. Although this approach leads to a better image on the screen, is to put the question of legitimate marketing. If a 17 "monitor have a 17" screen? I think so, but apparently there are no display manufacturers. So, when buying a CRT monitor, not just look at the screen and check the visible region, which tells you exactly how much screen you can use. Also, do not forget to look at the monitor dot pitch (the lower the better) and its maximum resolution (higher is better).
