Fix 1: Restart your PC

Sometimes the No Video Input problem is just a temporary error that can be fixed by restarting your PC. (You can force-shut down your computer by pressing and holding the power button for 3 to 5 seconds. Then turn it back on.)

If your issue persists after the reboot, then go ahead with the next fix.

Fix 2: Check your video cable

If your video cable has become loose, the image signal won’t be transmitted and it can cause the No video input message on your monitor. So, you want to make sure that your video cable is functioning correctly, then reconnect your monitor to your computer. Follow the instructions below:

1) Press and hold the power button until your computer turns off.

2) Unplug the video cable that connects your monitor to your computer.

3) Check the port connectors on your computer and your monitor.

If any connector on your device is bent or damaged, you’ll need to take the device to a repair shop.

4) Check to see if your video cable is damaged.

If the video cable is fine, reconnect your computer to your monitor. Or, if you have another video cable available, try connecting the two devices using the new cable.

5) Try turning on your computer to test your issue.

If you run into the No Video Input error again, read on and check the fix below.

Fix 3: Plug the cable into the right video port

If you’re using a desktop PC, check if your display cable is connected to your motherboard instead of your graphics card port.

Fix 4: Disconnect your peripherals

Peripherals connected to your computer may also prevent your monitor from running properly and cause the No Video Input issue. Try disconnecting all peripherals to see if that fixes your issue. Here is how:

1) Press and hold the power button until your computer turns off.

2) Disconnect all peripherals (your webcam, printer, scanner, mouse, etc.).

3) Try turning on your computer again.

If your monitor works correctly, that means that one of the peripherals you removed is causing the problem. You should reinstall each device back into your computer and test them each time. Then, you’ll find the specific device that causes your problem.

Replace the problematic device once you’ve identified it. Or, consult the manufacturer of the device for assistance.

If your monitor still won’t work, try the fix below.

Fix 5: Reset your BIOS settings

Improper BIOS settings can also cause your monitor to fail. To see if that’s the core issue, you should reset your BIOS to factory settings. Here is how to do it:

1) Press and hold the power button until your computer turns off.

2) Disconnect the AC power cord from the power supply, and then open your computer case.

3) On your motherboard, remove your CMOS battery with your fingernail or a non-conductive screwdriver.

4) Wait for 5 minutes, and then reinstall your CMOS battery .

5) Connect the AC power cord to the power supply, and then turn on your computer.

If your problem still exists, try the fix below.

Fix 6: Reinstall your RAM and graphics card

In some cases, the No Video Input error might occur if your hardware isn’t properly installed. If you’re comfortable opening your computer case, try reinstalling your RAM and graphics card to see if that fixes your issue. Follow the instructions below:

1) Press and hold the power button until your computer turns off.

2) Disconnect the AC power cord from the power supply, and then open your computer case.

This process will vary depending on different types of computers. If you don’t know how to do it, consult your computer’s documentation or seek professional help.

3) Remove the RAM.

On your motherboard, you should notice two tabs on either side of the memory slot. Press each tab down and away from the memory slot. If done correctly, the memory should pop out and once both tabs are away from the memory module you can lift the memory out with no effort.

RAM looks like this:

If the problem continues to occur, you may want to bring your PC to a repair store and seek professional help.
