The video output stopped working. At first it was intermittent, but it finally quit. The monitor is good, I've also tried several different monitors.

Then we have to suspect some issue with the video card or embedded card or maybe bios.

Simple enough to try is remove video card and re-seat. Turn off computer and pull ac plug. Press power button a few times and use ground wrist strap to ground while you remove the video card and reset. Reverse to test.

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.

Oh, shoot. You can't play with a laptop adapter.
