HDMI monitor says 'No Signal' and won't display anything
An HDMI connection issue is blocking the signal from your computer to your monitor. We'll check the cable, unplug and replug it, and make sure Windows detects your monitor.
HDMI carries both video and audio from your computer to your monitor through a single cable. When the connection is loose, the cable is damaged, or Windows hasn't detected the monitor yet, you get a 'No Signal' message. We'll secure the cable, reset the connection, and get Windows to recognize your monitor.
- ✓Make sure both your computer and monitor are turned on
- ✓Make sure the monitor is set to the correct HDMI input (some monitors have multiple inputs)
- ✓Have the HDMI cable accessible so you can unplug and replug it
Fix-IT-Bot will walk you through each step, just tap, no typing needed.
Skip, I just want a technicianCommon mistakes to avoid
- Changing the monitor input setting repeatedly without giving Windows time to detect it — wait a few seconds between changes
- Thinking the problem is with your monitor when it's actually a loose cable — always check the cable first
Signs you need professional help
- If you've tried multiple HDMI ports, the cable looks good, and your monitor still says 'No Signal', give us a call — your HDMI port or monitor may have a hardware problem.
