What does vga no signal mean on your computer screen?

No VGA signal means that the VGA wire is not getting any video output from the CPU.

To Rectify:

• Check that the VGA cable is tight enough on both the ends.
• Check if the Pins of cable are broken or not.
• Your video card might be faulty.
• Try a different Monitor.
• If the other monitor works then the problem lies with the computer (motherboard video output)
