refresh rate - The image on your computer monitor doesn't just appear fully formed on the screen's phosphors: it's drawn line by line with beams fired from three electron guns at the back of the CRT. (The three guns are for different colors--red, green, and blue. The colors blend to build all the colors you see.) The frequency at which they redraw the image is called the refresh rate, and it's an important measure of how steady the image will appear.
A refresh rate of 60 Hz (in which the screen is redrawn 60 times per second) will almost always look flickery--especially under fluorescent lights, which refresh at about the same rate. This causes eye fatigue. Refresh rates of 70 Hz and higher are preferable. Since refresh rates can vary depending on the screen resolution you pick, check that both the monitor and display adapter you run can manage a 70-Hz or higher refresh rate
