This uncompressed interface lets large streams of audio/video digital info be transmitted at high speed, reducing the number of cables you need to set up, by way of a set-top box, DVD player or AV receiver, or an audio/video monitor like your digital TV.
When HDMI connected components cannot recognize and communicate with each other, the HDCP encryption embedded in the signal isn’t properly recognized by one or more of the components connected, thus you get HDMI no signal.
If this is the case, or what you’re experiencing, then there are some solutions you can use to fix it.
How do I fix an HDMI with no signal?
- Update the chipset and graphics drivers
- Troubleshooting tips
- Change turn-on sequence
- Check resolution output settings
- Change the HDMI connection
- Check for firmware updates
1. Update the chipset and graphics drivers
The first step here is to download the chipset and graphics drivers for your model, then do the following:
- Right-click Start and select Device Manager
- Open Display adapters
- Right-click on your graphics chip and select Properties
- Select Driver tab
- Click Uninstall
- Do the same for the graphics driver
- Go to the downloaded drivers files (chipset and graphics drivers), and install both, then restart your computer
- Go to the search bar and type Sound, then select Sound from search results
- Click Playback tab
- Right-click HDMI and set as default.
- If you don’t see HDMI, right-click any device and select show disabled devices.
- Now you should be able to set HDMI as default. Click OK or enter.
Keep in mind that downloading and updating drivers manually from the manufacturer’s website can damage your system by choosing and installing the wrong driver version. In order to prevent that, we strongly suggest to do it automatically by using DriverFix.
This tool is approved by Microsoft and Norton Antivirus and will help you not damaging your PC by downloading and installing the wrong driver versions.
After several tests, our team concluded that this is the best-automatized solution. Below you can find a quick guide on how to do it.

2. Troubleshooting tips
Before you try the other solutions below, check your HDMI connections such that they don’t slip out as they tend not to fit as snug as component or composite video connections and any slight move can make them slip out.
You can also get locks for the HDMI cables or buy self-locking cables.
Most HDTV devices have multiple HDMI input ports so it is important that the HDMI display input source is set to the same one as the HDMI port connected to your computer e.g. HDMI 2 to HDMI 2.
If the computer and HDMI device use different cable types, buy adapters.
3. Change turn-on sequence
You can try a different turn-on sequence like instead of turning on the monitor first then the media player, or another HDMI source component, try turning on in the reverse and see if it helps.
If your media player or other component is connected to a home theater receiver, then to the monitor, try different combinations to startup the devices and use the one that works.
If this doesn’t fix HDMI any signal issue, try switching to a different input on the monitor and switch back to HDMI to check if the signal locks incorrectly. Once you get the best sequence, note it down for future use.
You can also try the following steps:
- Disconnect all HDMI sources from the inputs.
- Unplug the power from TV (monitor)/LCD for about ten minutes.
- Plug the TV (monitor)/LCD back in.
- Connect the HDMI cable one device at a time.
- Turn on the device
Repeat the last two steps for each HDMI port.
4. Check resolution output settings
If your player or any other HDMI source device has a video resolution output setting, check whether it has been set to Auto, and if it is, reset it to match your monitor’s native resolution or that of your video projector. Check if that provides better stability.
5. Change the HDMI connection
If changing the turn-on sequence doesn’t work, try directly connecting your player to the monitor, as this bypasses the home theater receiver, so you can check if the latter is the likely culprit when the direct connection works.
In this case, keep the HDMI source in direct connection to your monitor and have a separate audio connection to the receiver.
6. Check for firmware updates
If none of the above solutions work, check if there are any firmware updates announced for your HDMI source or home theater receiver, or even the monitor itself, which can resolve the HDMI no signal issue.
