A Brief Guide – How To Enable The HDMI Port On Your Computer:

Step 1:

First, you must have an HDMI cable.

I suggest you get this HDMI cable at a cheap price.

If you have that, you can skip this step and move on to the next step.

Step 2:


Next, you need to take your computer near the device which you want to use as a display in order to enable the HDMI port on your computer.

This device can be a monitor, projector, or maybe a TV.

Now, you have to insert one end of an HDMI cable into your computer port.

Let’s move on to step 3.

Step 3:

After inserting one end of the cable into your computer, you need to turn on the external device that you are using as a display.

After turning on the device, insert the second end of the cable into the “HDMI IN” port on your monitor.

The computer screen will flicker and HMDI output will turn on and the device will display the output.


Sometimes, the external device might not display the correct resolution when the HDMI is connected. In order to correct it, you have to follow just simple step:

  • Just right-click on the desktop, click “Screen Resolution”.
  • The next window will appear after clicking Screen Resolution.
  • From the next window click the “Multiple Display” option.
  • Find the option “Show Desktop On Monitor 2” and click on it.

After doing that you’ll notice that the screen will flicker and the external device will display the computer’s video output.

Still HDMI Port Not Working?

So, here I’ve done deep research, especially for you. I’ve analyzed that many people are facing different types of difficulties. Therefore, I have enlisted and explained some of the most important difficulties that folks are facing.

So let’s get started.

HDMI is considered one of the most efficient ways to connect all the related devices conveniently together. This whole connection only requires one cable for both video and audio.

For this purpose, the connected devices should be certified entirely or licensed for communication with each other by standardized high-bandwidth digital content protection.

If the HDMI handshake does not work, the HDCP encryption for HDMI is not identified by one of the connected devices. Ultimately, you will not watch your favorite video game or not even watch your favorite movie or TV show.

So here are some things that you may find helpful to sort out the issues of the HDMI port not working. If you follow one of these mentioned below methods, you will hopefully get your issue resolved.

1st Method – Configuration of Display Setting:

If there are several monitors on your laptop or computer and you face the HDMI port’s problem not working. Then there could be a possibility that you may use the setting of the wrong display.

In this case, it would be better to check out the laptop’s display setting and be sure to have the correct display setting instead of the wrong one.

So, to check out the display setting of the computer, first of all, click on the “P and Window logo key simultaneously. Here you will get the display modes list.

As each mode is different from the other, so, it is as given below:

  1. PC screen/Computer only – It only uses 1st monitor.
  2. Duplicate – It displays identical content on both monitors.
  3. Extend – It utilizes both monitors to display the extended desktop.
  4. Second screen/Projector only – It only utilizes the one monitor that may be second.

Practice each mode and then choose one of the best options that best suits your requirement. You will be able to see images on the screen through HDMI.

Second Method – Update Graphic:

Suppose you experience your HDMI port not working well. Then there could be another reason behind this happening, and this is your graphic driver.

If it is out of date and you still do not make sure of any update of it, you will indeed have to face this issue.

The solution is to update or reinstall your graphic driver and see whether it is helpful or not in problem resolution. 

For updating the graphic driver, there are two ways:

02. You can do it automatically:

It will recognize the system automatically and then find the right driver. It is as easy as you don’t even need what the computer system is running through, and you don’t require any skills to download and install the right driver.

Besides this, there is no risk of installing the wrong driver. So, don’t worry, and make sure to install the right graphic driver without any mistakes.

However, you can automatically update the drivers either with the Pro or Free version of the Driver Easy tool.

In case of HDMI port not working, if you prefer Pro Version, then it requires just a few simple clicks:

  • Download Driver Easy tool on the computer and install it.
  • After this, run the tool, and click on the button “Scan Now.” It will scan your device and show the issues of any detected drivers. 
  • Then click “Update all” for downloading and installing automatically the correct version of drivers that are out of date or missing.

Third Method – Reconnect or Restart your Computer:

If your HMDI port not working as before, then another method is to reconnect and restart your device. Sometimes, it proves an effective method to make the working of HDMI port.

Just follow these steps:

  • First of all, disconnect your HDMI ports.
  • Now shut down the computer, TV, monitors laptop, etc, and then unplug all the related power cables.
  • After this, left it for five to ten minutes.
  • Plug in all the power cables, including the battery.
  • Connect HDMI cables 
  • Now switch on the computer. 

Now make sure, that you can use the HDMI port or not.

4th Method- Troubleshooting:

If your HDMI port not working, then there might be a problem with the hardware like the HDMI port or cable. So, there are some minor things to do.

These include:

  • First of all, change the new HDMI cable. It will surely sort out the issue.
  • If even it does not work, try to make an HDMI connection with any other monitor or TV. Now note down the device. If it is defective, then replace it or repair it.
