Your monitor says 'No Signal' when you plug it in

The cable between your monitor and computer has come loose or isn't plugged in all the way. Turn off your monitor, push the cable firmly into the port on the back of both the monitor and the computer until it clicks, turn the monitor back on, and you should see your screen. If that doesn't work, try a different cable.

When your monitor shows 'No Signal', it means no picture is coming from your computer. This is because the cable connecting them isn't sitting properly in its port. Sometimes the cable itself is broken, or you're using the wrong type of cable for your monitor. We'll walk you through checking the connection, trying a different cable, and making sure Windows or macOS knows your monitor is there.
