Input Signal Not Found on Monitor: Troubleshooting Tips

If you are receiving an “Input Signal Not Found” error on your monitor, the most common cause is a loose cable. Make sure to reattach the cable running from your monitor to your PC and check for any visible damage.

If the issue persists, it could be due to overheating or incorrect monitor settings. Try checking the input/source settings on your monitor and ensure they are set correctly. Additionally, you can update your graphics card drivers and test with an alternative monitor or PC to troubleshoot the problem.

Disconnecting and reconnecting the HDMI cable may also help resolve the issue.

Verifying Monitor And Cables

If you are facing the frustrating error message “Input Signal Not Found” on your monitor, don’t worry, it is a relatively common issue that can be easily resolved. The first step in troubleshooting this problem is to verify the monitor and cables. Here are some steps you can follow:

Check Physical Cable Connections Between Monitor And Pc

Ensure that the cable connecting your monitor to your PC is securely attached to both ends. A loose connection can often be the culprit behind the “Input Signal Not Found” error. Make sure the cable is firmly plugged into the corresponding ports on both the monitor and the PC.

Inspect Cables For Visible Damage

Examine the cable for any visible signs of damage, such as frayed wires or bent connectors. If you notice any damage, it is best to replace the cable with a new one. Damaged cables can interfere with the transmission of the video signal and result in the “Input Signal Not Found” error.

Test Cables With Another Monitor If Available

If you have access to another monitor, try connecting it to your PC using the same cable. This will help determine if the issue lies with the monitor or the cable. If the second monitor displays a signal, then it is likely that the original monitor is faulty. On the other hand, if the second monitor also shows the “Input Signal Not Found” error, there may be an issue with the cable or the PC’s video output.

By following these steps and verifying the monitor and cables, you can effectively troubleshoot the “Input Signal Not Found” error. Make sure to check the cable connections, inspect for visible damage, and test with another monitor if available.
