How do I fix a D-SUB message appearing on my screen. When I power my computer, it powers OK, then the monitor will be on for 2 to 3 seconds then off but before going off it displays a “D-SUB” message for that 2 – 3 seconds.
What could be the cause? I have tried connecting it to a different PC but still displays that and goes off. I now use a different monitor because it is my office PC. Please help.
