How to Fix No HDMI Signal from Your Device [5 Tested Tips]

HDMI is a digital audio or video interface that delivers crystal clear sound and pictures through a single cable by simplifying cabling so you can get the highest quality home theatre experience.

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, AV receiver, or an audio/video monitor like your digital TV.

How do I fix no HDMI signal from your device?

Before trying the other solutions below for the no HDMI signal from your device problem, check your HDMI connections so that they don’t slip out as they tend not to fit as snug as a component or composite video connections 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 essential 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.

1. Update the chipset and graphics drivers

1.1. Update drivers manually

1. The first step is to download your model’s chipset and graphics drivers.
2. Right-click Start and select Device Manager.
   
3. Click the arrow next to Display adapters to expand it.
   
4. Right-click on your graphics driver and select the Uninstall device option.
   
5. Click the Uninstall button to confirm the action.

8. Press the Windows key + S, type control, and select Control Panel.
   
9. Select the Hardware and Sound option.
   
10. Now choose the Sound option.

2. Change turn-on sequence

You can try a different turn-on sequence instead of turning on the monitor first, then the media player, or another HDMI source component; try turning it on in reverse and see if it helps.

If your media player or other component is connected to a home theatre receiver, then to the monitor, try different combinations to startup the devices and use the one that works.

If this doesn’t fix the HDMI signal issue, try switching to a different input on the monitor and switching 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:

• First, disconnect all HDMI sources from the inputs.
• Unplug the TV (monitor)/LCD power 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 as it is also possible to stumble across an HDMI port that does not work.

3. 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. If it is, reset it to match your monitor’s native resolution or that of your video projector. Check if that provides better stability.

4. Change the HDMI connection

If changing the turn-on sequence doesn’t work for the no HDMI signal from your device issue, try directly connecting your player to the monitor, as this bypasses the home theatre receiver, so you can check if the latter is the likely culprit when the direct connection works.

In this case, keep the HDMI source directly connected to your monitor and have a separate audio connection to the receiver.

5. Check for firmware updates

If none of the above solutions works, check if any firmware updates are announced for your HDMI source or home theatre receiver. Also, you can check for firmware updates for the monitor itself, which can resolve the HDMI no signal from your device issue.

This is because outdated firmware can block your connection and cause many issues. Besides, many users have reported Windows 10 HDMI has no signal after update, which too can be fixed by installing the latest version of the firmware.
