Display Switch is Set Incorrectly

Display Switch is Set Incorrectly

If you have arrived here through a search engine, and there’s no menu to the left click here!

Explanation: Some older PCs (and we do mean older) have a switch on the motherboard that can be toggled between “monochrome” and “color”, instead of having a BIOS setting to control display type. The BIOS POST has detected a mismatch between this setting and the video card it detects in the PC.

Diagnosis: The display switch is set incorrectly, there is a video card problem and a required setting in the BIOS has not been made, or there is a motherboard problem.


  • Check your system manual to find out if you have a display type switch, and if you do, make sure it is set correctly.
  • Troubleshoot the video card.
  • Troubleshoot the motherboard.
