Problem When setting up a PC or other computer equipment with a CRT type display, most IT proffesionals does not fine tune the setup of the graphics card. As a result most CRT monitors today flicker at the default refresh rate, typically 60 Hz. Most workplace regulations prescribe 'flicker free' or 70 Hz+ refresh rates. So far, the only way of checking the refresh rate was to see it in the windows driver, find it in the OSD menu, or use an external measuring device. The industry have deviced new technologies (PnP, DDC) to remove these problems, but they persist in end user environments.
