[0] Screen Flatness [CRT] Many manufacturers tout true flatness for their CRT monitors, but the sad truth is that most are fake. In reality it is only the outer glass that is flat, and not the actual screen. The true 100% perfect flat monitors are the aperture grille tubes made by Mitsubishi and Sony. Even then, these tubes have a disadvantage - a faint thin line or two (Depending on size) running through the screen to stabilize the grill. Some people find this distracting, especially if you work on a light background (eg. documents) most of the time. [LCD]
