Your monitor shows 'No Signal' or goes black
The cable connecting your computer to your monitor is probably loose or disconnected. We'll check and reseat it, then make sure Windows detects your display.
Your monitor connects to your computer with a cable that carries the video signal. When the cable is loose, unplugged, damaged, or not fully connected, the monitor can't receive the image and shows 'No Signal'. We'll check the cable, secure it, and check that Windows sees your monitor.
