What is important besides monitor size?
A. Screen resolution and the refresh rate of the monitor are also important. Generally, the larger a monitor is and the higher resolution it has, the harder it is to get the high refresh rate that is required for sustained viewing without screen flicker. The optimum threshold for minimum flicker is generally considered to be a horizontal refresh rate of 72 Mhz on a 21″ monitor. The maximum refresh rate is a function of the monitor and the graphics controller.
