Monitor says 'No signal detected' when connected to computer
The cable connecting your monitor to your computer is loose, damaged, or plugged into the wrong port. Unplug both ends of the cable, wait 30 seconds, and plug it back in firmly. This fixes it for most people immediately. If that doesn't work, your computer may not be detecting the monitor and needs a driver update.
A 'No Signal' message means the monitor and computer aren't talking to each other. The cable connection is almost always the problem. Sometimes the cable is loose, kinked, or the plug got accidentally pulled out partway. If the cable is fine, the issue is in most cases a missing or outdated driver that needs to be reinstalled.

- Plugging the cable into the motherboard's video port instead of the graphics card port. if your computer has a graphics card, use that port
