Ensuring a Tight Connection

A HDMI port doesn’t have a self locking mechanism like a Display port cable might have. That is why its very possible that the connection you have is just simply loose.

If you use the HDMI port of your laptop often, or your laptop is just a few years old at this point. You might find that the HDMI cable tends to slip out of the port. 

This could be the reason you losing your display connection constantly. You could try cleaning out the internals of your HDMI with compressed air to see if that fixes the issue.

But be sure to not use any sharp objects to get out any debris from inside the port. The connectors inside an HDMI port are very fragile, and if you even slightly scratch one it could be game over. 

If the cable still keeps slipping out from your HDMI port, then maybe you should consider purchasing an HDMI lock. There are a few available on Amazon, we’ll link the best one we could find below as well.

What these essentially do is support the HDMI cable by mounting the lock to your laptop chassis. This way it stays in place, and doesn’t slip out.

Ensuring You Have the Proper Cable.

Believe it or not, but not all HDMI ports are created equal on Laptops. HDMI was first introduced all the way back in the early 2000’s and since then we’ve gone through multiple versions of it.

The most current version is HDMI 2.0 that was introduced in November of 2017. This has a max supported bandwidth of 48 Gbits/s. Thats many times more than HDMI 1.0’s 4.95 Gbits/s transmission bandwidth.

So if your trying to run a HDMI 2.1 display connection on a cable that only supports HDMI 1.4 for example. Then that could be your issue right there.

Google your laptop make and model to find out what type of HDMI version port it has. Then be sure to purchase an HDMI cable that has enough bandwidth to support it.

Trying Different HDMI Cables

This might seem like a pretty obvious solution but it can be often overlooked. If you have spare HDMI cables lying around your house then try testing those out with your laptop.

It could be that you were working with a faulty cable all along. 

Checking For Issues In the External HDMI Display

There is a possibility that both your laptops HDMI port, and your HDMI cable might not be the culprit of your issues. It could actually be the external display or TV your trying to connect too.

First of all if your display has multiple HDMI ports test a connection in each one of them. If you have another laptop or PC in your house try connecting that to the display.

If even then you face issues, then it could very well be an issue with the display. Maybe it’s HDMI port has worn out, or it has some other hardware related issue.

If your connecting to a TV make sure you have the proper input selected on your TV. It could be that you connected your laptop to HDMI 3, and your TV is displaying HDMI 2 and you spent all this time diagnosing for nothing. 

Running Windows Troubleshooter

Your very last option is to try running the Windows Troubleshooter to see if it can highlight any issues of why your HDMI port isn’t working right.
