Input Signal Not Found on Second Monitor: Troubleshooting Tips

If you are experiencing an “Input Signal Not Found” error on your second monitor, try turning the display off and then on again to reset the video feed. Additionally, make sure that all cable connections are secure, as a loose cable can often cause this issue.

If the problem persists, it may be necessary to check for any faulty or disconnected cables.

Confirming Basic Connections

When encountering the “Input Signal Not Found” error on your second monitor, it’s crucial to start troubleshooting by confirming basic connections. This step ensures that all the necessary physical connections are in place and properly set up. By following the steps below, you can quickly identify and resolve common connection-related issues.

Ensure Monitor Power Is On

In some cases, the simplest solution to the “Input Signal Not Found” error is to ensure that your second monitor is powered on. To do this, follow these steps:

1. Verify that the power cable is securely plugged into the monitor.
2. Check if the power button or switch on the monitor is pressed or toggled to the “On” position.
3. If the monitor has a separate power supply, double-check that it is properly connected to an electrical outlet and turned on.

Check All Cable Connections

A loose or faulty cable connection is a common culprit behind the “Input Signal Not Found” error. To check your cable connections, proceed as follows:

1. Inspect the cable connecting your computer or video source to the second monitor (e.g., HDMI, DisplayPort, DVI, VGA) and ensure it is securely plugged into both the video output port on your computer and the corresponding input port on the monitor.
2. If using an adapter or converter, make sure all connectors are tightly secured.
3. If possible, try using a different cable or a different video output port on your computer or video source to rule out any cable-related issues.

Verify Input Source Selection

Incorrect input source selection can also lead to an “Input Signal Not Found” error. To verify and adjust the input source selection on your second monitor, follow these steps:

1. Access the monitor’s built-in controls, usually found on the monitor itself or through an on-screen display (OSD) menu.
2. Using the monitor’s controls, navigate to the input source selection or input settings.
3. Select the appropriate input source that matches the cable connection used (e.g., HDMI, DisplayPort, DVI, VGA).
4. Save and exit the input settings.

By following these steps to confirm your basic connections, you can address common issues that may cause the “Input Signal Not Found” error on your second monitor. If the problem persists, further troubleshooting might be required, focusing on video drivers, display settings, or hardware compatibility.

Signal Path And Hardware Checks

When encountering the “Input Signal Not Found” error on your second monitor, it is essential to perform signal path and hardware checks to identify and resolve the issue. These checks will help ensure that your cables are properly connected and functioning, and that your monitor is receiving a video signal.

Inspect Cable Integrity

Start by inspecting the integrity of your cables. A loose or damaged cable can often be the cause of the “no signal” error. Check both ends of the video cable connecting your computer to the second monitor. Ensure that the connectors are securely attached and there are no bent or damaged pins. Oftentimes, simply reseating the cable can resolve the issue.

Test With Alternate Cables

If inspecting the cable does not resolve the issue, it is recommended to test with alternate cables. Sometimes, the cable itself can be faulty, leading to the “no signal” error. Swap out the current cable with a known-working one to determine if the issue lies with the cable. Connect the alternate cable between your computer and the second monitor and check if the monitor receives a video signal.

Swap Out For A Different Monitor

If the previous steps do not resolve the issue, it is advisable to swap out your second monitor for a different one. This will help determine if the problem lies with the monitor itself. Connect the replacement monitor to your computer using a known-working cable and check if the “no signal” error persists. If the replacement monitor displays the video feed correctly, it indicates that the original monitor may be at fault.

Graphics Card And Driver Solutions
