If you’re having trouble connecting your monitor or TV to your computer you might be experiencing a motherboard hdmi no signal problem. In this article we’ll go over a few ways to diagnose the problem. In addition to testing the HDMI cable we’ll cover how to enable onboard graphics on your motherboard. This problem is usually caused by out-of-date drivers. Luckily there are several ways to update these drivers.

Troubleshoot a black screen on a motherboard

If your PC suddenly starts to display a black screen it may be caused by a few different factors. The motherboard might not be detecting your monitor properly or the video cable may be defective. It could also be that your computer has no signal at all. If you suspect the problem is due to a malfunctioning monitor you can attempt the following troubleshooting steps.

The most common cause of a no-signal problem is a cable. Sometimes a cable may be damaged or have debris that has built up in its port. To check the cable try rubbing it lightly along it to see if it’s completely free of debris. If the cable still doesn’t work properly with your new monitor you may need to buy a new one.

Diagnose a motherboard hdmi no signal

When your HDMI port no longer works you should start by checking the connection to the monitor. If the cables are properly plugged in and firmly attached to the monitor the problem is likely caused by an ill-connected GPU. If you have another HDMI input you can use that instead. However if you don’t have a spare HDMI port you should replace the board with an Intel motherboard with an integrated GPU.

If the problem persists you should try replacing the CMOS battery. This battery is a small silver coin and is usually located inside the computer’s motherboard. Ensure that the battery drains for about a minute. Also check if your monitor has a graphics card port. If so it may require an adapter. Active adapters work by converting digital signals into analog ones but they require an additional power cable.

Test an HDMI cable

If you’re experiencing no signal from your HDMI port on your motherboard the first thing to check is whether or not you have properly connected your cables. If you’ve checked everything else and you still don’t have a signal try plugging the cable into an HDMI port that you do have available. It may be a loose connection or the monitor is not seeing your computer. It’s possible that your HDMI cable has been damaged or your motherboard doesn’t support it.

If your HDMI port is stable and working then try plugging an HDMI cable into a secondary adapter. If your HDMI port is not working you can try using another port such as the VGA or DVI. Sometimes the problem may be with your motherboard so you might need to call in an expert. Sometimes your motherboard might not be the cause of the problem but it can be very frustrating.

Enable onboard graphics on your motherboard

If you are experiencing a problem with your computer’s onboard graphics you may need to enable it. If this does not solve the issue you should check your motherboard’s manual. You can also view a video tutorial to learn how to do this. If you are unsure of how to do it the manual will provide step-by-step guidance and videos. Depending on your computer you may need to press different keys on the keyboard to enter BIOS. The most common ones are Escape Delete F1 F2 and F8. The manual for your motherboard should list the keys as well as where they can be found.

After you have located the BIOS go to Advanced Settings. If you do not find any settings under this menu look for ‘IGPU.’ If your CPU has an option to enable this check it with the manufacturer’s website to see which updates are available. If you have not enabled IGPU disable it and try again. If you have enabled it the motherboard’s HDMI will work.
