How to fix "no input signal" error message

Updated: 06/30/2020 by Computer Hope

Black computer screen.

If your computer monitor is displaying the error message "No Input Signal," try the troubleshooting options in the sections below.

Computer not transmitting a signal

Make sure the computer has power. If the computer is turned off, it cannot transmit a signal and causes the "no input signal" message.

Monitor not connected properly

Verify the monitor cable is connected correctly and securely on the back of the monitor and the back of the computer. The monitor cable connects to the back of your computer using either a VGA, DVI, HDMI, or DisplayPort connector. The pictures below are examples of the VGA, DVI, HDMI, and DisplayPort connectors on a video card.

DVI connector

USB-C, DisplayPort, and HDMI video ports

Verify the monitor cable is not loose by disconnecting the cable from the back of the monitor and reconnect the cable. It's also a good idea to rock the cable back and forth to make sure it's not loose.


When disconnecting the cable, make sure none of the cable's pins are bent by examining the end of the cable. If any of the cable's pins are bent or broken, the cable may be defective and should be replaced.


Some older monitors may have cables that cannot be disconnected from the back of the monitor.

Next, disconnect the monitor cable from the back of the computer and reconnect the cable. When connecting the cable to the computer, ensure the cable connection is tight. With a VGA or DVI style connector, like the ones shown above, screws can be tightened and hold the connector in place.


Some computers may have an onboard video and a video card. When working with this type of computer, you'll have two different connections for your monitor on the back of your computer. If you see more than one VGA, DVI, HDMI, or DisplayPort connector and the monitor is not working, try the other connector.

Incorrect input selected

Newer monitors are capable of connecting to a computer using a VGA, DVI, HDMI, or DisplayPort connector. For these types of monitors, the correct input selection needs to be used. Access the settings on the monitor using the buttons on the front or bottom edge of the monitor. Look for options to select the type of connector (e.g., VGA, DVI, HDMI, or DisplayPort), and select the cable your monitor uses.

Bad hardware

If the connections appear to be correct, either the monitor or the video card is likely bad. It's also possible that the motherboard in the computer is defective, preventing a signal from getting to the video card and monitor. To test what component is bad, either connect a different monitor to your computer or connect your monitor to a different computer. We recommend testing the motherboard for any issues, as well. See: How to test a computer motherboard and CPU for failures.

  • If another monitor works on your computer, the monitor is bad.
  • If your monitor works on another computer, your video card may be having issues. See: My video card isn't working.

If you believe your video card is bad and your computer has an onboard video, the motherboard needs to be replaced. You could also install a new video card instead of replacing the motherboard. See: How to install a computer video card.

Computer not posting

Verify your computer is getting past the POST process and that it is starting up. The "No input signal" message can sometimes appear if the POST process is failing, and the computer cannot boot properly.

If the POST process is failing and the computer is not starting up, the motherboard could be at fault. A short in the motherboard or a bad capacitor are common causes for a computer motherboard to not pass the POST process.

Monitor works for a while, then loses signal

If the monitor works for a while, then stops working and displays the "No input signal" message, the monitor or computer may be overheating. In the event of the monitor overheats, it stops working to prevent further damage. If the computer overheats, the computer may stop sending a signal to the monitor, and may also shut down to prevent further damage to the computer hardware.

Fixing a monitor that is overheating is generally not worthwhile. The cost to fix it is likely more than the cost of buying a new monitor. For that reason, we recommend replacing an overheating monitor.

If the computer is overheating, the fans that keep the processor, video card, or power supply cool may have failed. Check the fans to see if they are spinning. If they are not spinning at all when the computer is turned on, the fans need to be replaced. If the fans are spinning, use a software diagnostic tool, like HWMonitor, to determine if the fans are spinning at the correct RPM. It is possible that the fans are not spinning fast enough, indicating they are bad or full of dust and need to be cleaned or replaced.

If the overheating is related to the computer processor, you may need to replace the heat sink and fan assembly. It's possible that the CPU may be damaged and needs to be replaced, as well.

For a video card or power supply, the fans are usually integrated into the hardware and not easily replaced, if they can be replaced at all. You may need to replace the power supply or video card to fix the overheating problem.

How to troubleshoot no display on computer monitor.

There can be a number of reasons why a desktop computer monitor is not displaying an image. Before taking your computer or monitor to your local repair shop you can try some easy troubleshooting steps below to help determine the cause of your display issue.

Please Note: We have received a large number of support requests related to this article. While we do offer FREE troubleshooting tips on our website we are unable to offer free one-on-one support. If you’re interested in paid phone/remote support feel free to contact us.

If Monitor Displays “NO SIGNAL” or “SELF TEST” – this means that your computer monitor is working properly but isn’t getting a signal from the computer. Start troubleshooting your issue by ensuring that both ends of the video cable that goes between your computer and your monitor are pushed in the whole way. Your monitor cable will look like one of the three examples below. If you have a VGA or HDMI cable be careful not to screw the adapter in place too tightly. You also want to be careful not to pull on the cable until the screws have been loosened completely from the back of the computer. 


Monitor power light is off –  If your monitor is not displaying a power light then you might have a problem
with your monitor. Ensure that the power adapter to the monitor is plugged in completely. Test your power outlet with another device such as a lamp to ensure the power outlet works. If you havMonitore another cable that matches your monitors power cable you can try using that or take your monitor to a local repair shop to see if they can test your monitor. If you have another monitor that you can plug into your computer you can test that just to rule out any potential issues with your computer.

My monitor has power but I have no display – usually this points to a video card or display driver issue. You can first check to make sure your video cable is plugged into the proper display port on the back of your computer. If you have two separate areas on your computer that have the same display adapter your computer has on-board video as well as a video card. Try plugging into the video card (usually away from other connections) first and if no-signal or self test is displayed on your monitor try the other port. 

What should you do if I still have no display on my computer monitor?

If the above don’t resolve your issue you may need to take your computer to a local computer repair shop for additional troubleshooting and support. Your technician will want to see your computer tower first to ensure that the display output from your computer is working properly.

If your computer displays properly on another monitor your technician can check to ensure that your screen resolution isn’t set too high for the monitor your normally use.  If the resolution is within normal ranges your monitor may need repaired or replaced. Replacing your out of warranty monitor may be the most sensible option depending upon the monitors age and specifications. 

If your computer does not display properly on another monitor your technician will need to perform further diagnostics to determine if other components including motherboard, memory or power supply are contributing to the lack of display. 

If your computer requires a new video card the cost of the repair will depend upon the quality of parts purchased and the video requirements that you need. If your using your computer for gaming or programs that are graphics intensive the cost of your video card will be higher. Basic video cards can cost as little as $49.99 or even less but you don’t want to sacrifice too much quality for price. The video cards that we purchase for the average gamer is around $150. Part installation fees can vary from repair shop to repair shop at Jester’s Computers we charge $15 for part installation.

New PC connected to monitor via HDMI but no signal

@AlexArcherPKFR, welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you out.

I understand that your OMEN by HP Desktop PC - 870-126na does not detect the monitor when connected by HDMI cable.


Don't worry as I have a few steps that should help fix this issue.


This issue has occurred because the normal HDMI port gets disabled when the graphics card is installed.


Hence, you need to connect the HDMI cable to the Graphics card port on the desktop PC which is next to the port that you have connected.


Let me know how that works.

I hope you have a good day ahead.

No ibuypower signal monitor pc

Plug it in, switch it on—it sounds easy enough to get your PC running, but it isn’t always that easy. It doesn’t matter if your PC fans are spinning if you’re seeing nothing on your monitor that allows you to actually use it. A no signal error on a monitor can leave you scratching your head without answers.

Thankfully, this kind of problem is usually easy to troubleshoot. If some of the more common fixes don’t work, then it points to a likely hardware fault that you’ll need to investigate for repair or replacement. To help you deal with display issues, here are some troubleshooting tips you can try when your PC monitor has no signal.

Check Your Cabling and Power

Before you rush to rip out your graphics card or head to Amazon to buy a new monitor, you should look carefully at your PC and monitor to ensure you have no cabling or power issues.

This is a simple check to complete. Start by tracing the cabling between your monitor and PC to ensure that you have no loose connections. A loose HDMI cable, for instance, could be preventing the output from your PC from being displayed (and vice versa).

You may also find that the display cable itself is at fault. If you see cable damage, or if the cabling is quite old, swap it out for an alternative. This can sometimes immediately resolve any issue with your monitor display.

There could also be a power issue that prevents your monitor from working correctly. If your monitor is displaying a no signal error, then you can assume your monitor has power, but if your PC isn’t on, you won’t see any error displayed.

Is The Monitor Input Source Correct?

A no signal error on a monitor could be a sign that your PC monitor is ignoring the graphics output from your PC. This can sometimes happen if the input source on your monitor is set to the wrong device.

Most display monitors have multiple input sources available, including VGA, HDMI, and DVI inputs. This allows you to connect multiple devices to the same display. This could be several PCs, or a PC and a games console, which you could then switch between using your monitor’s firmware menu or physical controls.

If this is the case, make sure that the input source on your monitor is correctly set. If it isn’t, switch to the correct source (for example, HDMI or DVI for modern PCs) to get your monitor working again.

Check Monitor Resolution

A PC monitor has a set range of display resolutions that it can use to display your PC output. If your PC’s graphics card is set to a display resolution above what your monitor is capable of displaying, you’ll likely see a blank screen or a no signal message appear.

Thankfully, fixing a blank monitor screen after changing your display settings is an easy process. If the monitor has suddenly lost resolution after changing the settings yourself, wait 15 seconds—Windows will revert back to your previous resolution after this point.

If you’ve haven’t recently changed your display settings, then your monitor resolution could have been changed automatically. There are ways to get around this, including restarting Windows and booting into Safe Mode to bypass the issue with a higher resolution.

By default, Windows will use a much lower display resolution in Safe Mode than during normal use. This will allow you to change your standard display resolution to a lower setting that your monitor can support.

If you’re unsure what resolutions are supported by your monitor, you should consult your user manual or the manufacturer website to find out. Alternatively, use the 15-second window to change your resolution for a bit of a trial-and-error. If the resolution stops your monitor from working, Windows will revert the setting to the previous setting that worked.

Update Your Graphics Card Drivers

When a display problem occurs, the monitor itself can often be the focus of your diagnostic efforts, but the graphics card your PC uses is often the bigger culprit. If you’re seeing a blank screen on a new monitor, then it’s likely that a new graphics card driver is in order.

As we’ve explained above, your PC can sometimes use a resolution outside of the range supported by your monitor. Equally, your monitor can sometimes support resolutions that your graphics card doesn’t yet support, especially if you’re moving to a 4K monitor or from a 60Hz to a 240Hz display. 

Thankfully, this is often resolved by updating the graphics card drivers (so long as the graphics card is relatively new). It’s recommended that you update your drivers on a regular basis to gain access to new features and bug fixes. This includes support for new monitors and display resolutions.

For instance, if you have an NVIDIA graphics card, you can easily update your NVIDIA drivers using Windows Update or, for the latest drivers, by downloading them from the NVIDIA website directly.

Test With An Alternative Monitor Or PC

If you’re confident that there isn’t a software issue (like outdated drivers) causing no signal to your display, then you may need to try an alternative monitor or PC as part of your troubleshooting efforts.

Replace the monitor attached to your PC with a spare (if you have one available). If the problem is replicated, this would likely indicate a problem with your PC that you’ll need to diagnose further.

Likewise, if your main monitor stops working, but a spare works fine, then this could indicate a problem with your monitor hardware. However, this does not necessarily rule out a further software issue. For instance, outdated drivers or incorrect display resolution could still cause this fault, so you’ll need to investigate further.

Replace Your Hardware

After thorough testing, if you’ve exhausted potential software fixes and any issues with your hardware can be replicated with other attached devices, then you’ll need to consider replacing your hardware.

For instance, a broken graphics card could stop any display output to your monitor, resulting in a no-input signal. If the drivers aren’t the problem, you would need to replace your graphics card.

Likewise, a broken monitor that doesn’t work with multiple devices isn’t going to fix itself. You should look at your repair options under warranty or, failing that, consider buying a new monitor.

This would also be a worthwhile decision if your monitor flickers or there’s a sign that the unit is starting to fail. This might be the case if your display takes a long time to switch on, for instance. 

Fixing PC Hardware Issues

When a monitor displays a no input signal error message, don’t panic. The steps above should help you troubleshoot the issue, but you may need to look at diagnosing your monitor or PC further to consider whether you’re due a replacement or repair under your device warranty.

Investing in the right PC hardware is essential—you don’t want to end up in the same situation a year or two into the future. Cheap isn’t always cost-effective, but make sure to consider your budget carefully before you rush to buy new PC components, or a new PC or monitor entirely.
