To attract buyers, manufacturers are now in an all out technology war, which can’t help but make us happy. There has been constant innovation in the form of artificial sweeping (black frame insertion), the first 24'' TN 3 ms, wide gamut, and the addition of HDMI inputs, etc.

They were meant to spell the end for 20 and 21 inch screens. And there is good reason. They are bigger and not more expensive (sometimes they are even cheaper). Also, recently some have cumulated advantages in design, reactivity, and colors.

A 30 inch LCD is a 76 cm diagonal and has 2560 x 1600 pixels totaling more than 4 million. This is equivalent to the amount of information displayed on five 15 inch LCDs or two 24 inch screens in a dual monitor configuration.

Why choose a 20'' over a 22''? Because of a lower price, less bulk, comparable reactivity, and identical resolution. Here is some advice for those wanting to buy a new screen and do not want to go broke in the process!
