If you have two monitors and they’re not working, make sure they are both plugged in and turned on. If this doesn’t work, try plugging the other monitor into a different USB port or use a different cable.

Try plugging in the power cable and turning on the computer to see if that fixes it. If not, try unplugging and then replugging in all of the cables that connect to your monitor. If none of these solutions work, you might need to replace your video card or monitor.
