Get Rid of Computer Screen Flicker
The Hz (Hertz) count of monitors, also known as "refresh rate," is the amount of times per second that the picture is re-drawn on the screen. A low refresh rate such as the one in image-projecting CRT monitors, which typically is either 50 or 60, gives the screen a flickering sensation to the human eye. Long-term exposure to refresh rates under 75 can give you both eye-strain issues and headaches, which is why it's a good idea to know set your screen to its optimal Hz setting.
