Monitor not detecting pc hdmi

Monitor not detecting pc hdmi DEFAULT

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.

HDMI Port Not Working [SOLVED]

Many computer users have reported problems with their HDMI port. They’re getting no image or sound coming out from their devices when they’re using that port. If you’re experiencing this problem, don’t worry. You’re not the only one… and you should be able to fix the problem quite easily using one of the solutions we’ve listed below. You don’t have to try them all; just work your way down the list until you find the one that works for you:

  1. Configure your computer display settings
  2. Update or reinstall your graphics driver
  3. Restart and reconnect your devices
  4. Troubleshoot hardware issues

Method 1: Configure your computer display settings

If you are using multiple monitors on your computer and you get an issue with your HDMI port, it might be happening because you’re using the wrong display setting. So it’s a good idea to check this setting on your computer and make sure you use the right settings to display your screen.

To check your computer display settings, press the Windows logo key and P on your keyboard at the same time. A list of display modes will appear.

The difference between each mode is as follows:

  • PC screen/Computer only — Only using the first monitor.
  • Duplicate — Displaying the same content on both monitors.
  • Extend — Using both monitors to display an extended desktop.
  • Second screen/Projector only — Only using the second monitor.

Experiment with each mode and select the option that is the best match for your needs. If your display settings are correct, you will be able to see images on the screen connected via HDMI.

Method 2: Update your graphics driver

You may experience problems with your HDMI port if you’re using an incorrect graphics driver or it’s out of date. You should try updating or reinstalling your graphics driver and see if this helps you resolve your problem.

There are two ways you can update your graphics driver:

Option 1 — Manually — You’ll need some computer skills and patience to update your driver this way, because you need to find exactly the right the driver online, download it and install it step by step.


Option 2 — Automatically (Recommended) — This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Option 1 – Download and install the driver manually

Your graphics adapter manufacturer keeps updating drivers. To get them, you need to go to its website, find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.

Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update the graphics driver

If you don’t have the time, patience or computer skills to update the graphics driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:

1) Download and Install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3)  Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

If you need assistance, please contact Driver Easy’s support team at [email protected].

Method 3: Restart and reconnect your devices

Sometimes restarting and reconnecting your devices is an effective method to get your HDMI port work again. Here’s what you need to do:

1) Disconnect all your HDMI cables from your ports.

2)Shut down all your devices (your computer, monitor and TV) completely and unplug their power cables (and battery if you are using a laptop).

3) Leave them for five minutes.

4) Plug the power cables (and the battery) back in.

5) Connect the HDMI cables back to your devices.

6) Power on the devices.

Now see if you can use your HDMI port.

Method 4: Troubleshoot hardware issues

If your HDMI connection is still not working, it’s likely there are hardware issues with your HDMI port, cable or your devices. In this case, there are a few things you need to do:

First, replace your HDMI cable with a new one. This will resolve any problems you might be experiencing due to your cable.

If changing the cable doesn’t work for you, try your HDMI connection with another TV or monitor or another computer. If there are problems with any of your devices, you should get them repaired or replaced.

How to Fix a No-Input Signal to a Computer

By Joshua Phillips

Computer monitor flicker is caused by a bad configuration or failing hardware.

When your business doesn't have an Information Technology department, it may fall on you to keep your computers running in the event of an error. If your monitor is displaying "No Input Signal," there is no image displayed from your PC to your monitor. There are several possible causes for this error. To fix it, you must determine which component is defective, ranging from the cables that attach your monitor to your PC to the monitor itself or even your PC's video card.

Unplug the cable running from your monitor to your PC and plug it back in, making sure the connection is firm. The most common cause of this error is a loose cable.

Reattach the cable running from your monitor to your PC. If the monitor is still not displaying a signal after firmly reattaching the cable, the problem could lie with the cable, especially if the cable has visible damage.

Replace your monitor with another monitor if possible. If the "No Input Signal" error still appears, the problem does not rest with the cables or the monitor, but with your PC.

Open your PC case and locate your video card. Remove the card and then replace it firmly in its slot or, if possible, insert the video card into another slot on your motherboard. A video card that is not making a firm connection will not display images to the monitor. Close your PC case and test the monitor again.

Replace your video card completely. Your video card may suffer from internal damage that is not allowing it to output a signal.



  • If you are still not receiving a signal even after replacing your video card, you may also need to replace the computer's power supply and, in a worst-case scenario, your computer's motherboard.
  • If your computer is still under warranty, arrange for an official repair before you open up your computer. Often, opening your computer yourself will void your warranty.


  • Always ground yourself by touching a metal object before touching any component in your PC case. Failure to properly ground yourself can result in damaged components.
