How to Enable Motherboard HDMI – in 3 Steps

The graphics capabilities of integrated graphics tend to be lower than those of discrete graphics. Nonetheless, budget-friendly builds are becoming more popular with them because adding a video card in most cases is rather expensive. 

A group of HDMI founders – Hitachi, Philips, Silicon Image, Matsushita Electric Industrial, and Toshiba – worked together on HDMI 1.0 in April 2002 in order to create a DVI-compatible AV connector. HDMI cables require the HDMI port to be enabled within your computer’s operating system before you can use them. An HDMI cable offers you the option to connect your computer with a projector or with another external monitor screen.  By enabling the HDMI port, you can easily send audio and video to any external devices connected.

The following is a complete step-by-step guide to enable the HDMI port on your computer. Before we get started, let’s review HDMI and why we need it.

What is HDMI?

Multimedia interfaces such as HDTV and home theater systems use HDMI (High-Definition Multimedia Interface) for audio-visual signals. An HDMI connector enables audio and video to be transmitted simultaneously from one electronic device to another. HDMI carries a bandwidth of 5Gbps (gigabits per second) with only 19 wires wrapped into one cable that looks like a USB cable. 

The motherboards of old computers were so overly simplistic that they only provided power and connections to essential components. HDMI, the first and only uncompressed, all-digital audio/video interface, has been widely accepted by the industry. 

As a result, HDMI is more attractive and convenient than its predecessors.  In the past few years, manufacturers have made the display output a basic requirement for motherboards, as computers offer numerous functions that require audio and video output. HDMI can be used to transmit standard-definition video or enhanced video as well as digital audio over a single cable. 

How To Check If Your CPU Has Integrated Graphics?

If your board has an HDMI port, make sure your CPU has integrated graphics since the HDMI port should be controlled by the integrated graphics instead of the GPU.  Some motherboard BIOS models only recognize certain CPU types.

Disabled Integrated Graphics: It’s possible to see that some manufacturers disable the integrated graphics in the BIOS of some motherboards with a discrete GPU. In those cases where it does not detect one, your integrated graphics will not function as well. You may want to speak with your manufacturer or a local computer store for more information on getting your CPU recognized by the BIOS if this is happening to you.

Fix The Issue: To turn on multi-monitor support for the CPU onboard graphics, press Delete or press F8 to enter the BIOS setup menu and then select Advanced/System Agent Configuration/Graphics Configuration.

Does your CPU have an integrated graphic card?

There are some CPUs that do not come with a graphics card, particularly old systems. In contrast to Intel’s modern processors, AMD’s do not usually come with integrated graphics.AMD Processors with the “G” designatory are the only ones to have one. You will therefore need an AMD CPU with a “G” designation, such as the AMD Ryzen 3 3200G, to use a motherboard HDMI port.

Fix the issue: To enable HDMI on your computer, it is important to ensure that your CPU supports integrated graphics. You could also google your processor model number in Google and Check Whether it has integrated graphics in the tech sheet.

Do not forget to be gentle with your motherboard. This step-by-step guide takes some computer expertise, but it’s not impossible. You will have to plan and research beforehand for this task and be gentle in your approach. Here are some crucial steps you should follow after you confirm your compatibility with your CPU

Step I: Enable Integrated Graphics in BIOS


BIOS UEFI is necessary for this process to begin. If you have not read the other topic related to other BIOS adjustments, only change the settings to enable integrated graphics. Motherboards differ greatly in terms of their BIOS interfaces. This helps to control the internal functions of your machine. Without the requisite knowledge, the BIOS settings of your computer can be easily altered, rendering it completely inoperable, even if you’re familiar with BIOS.

In order to enable the onboard display connectors in BIOS carefully, follow the steps below.

  • Reboot your computer. 

Be sure to save all important information and reboot the computer. 

  • Go to your motherboard’s settings and select the BIOS tab.

To get into BIOS, press the correct key as soon as the computer reboots. This will bring up the BIOS menu. This depends on your system. Check the user manual for your motherboard or go to the manufacturer’s website to find the exact key according to your system. Typical keyboard keys to use for this task include the Escape and Delete keys, along with F1, F2, F8, or F12. 

  • Navigate to Advanced Settings. Locate IGPU, Multiple Display settings.

There is a menu that assists you in finding the integrated graphics settings easily. Otherwise, go to the Advanced Settings and locate the Integrated Graphics Configuration/Internal Graphics. Choose “Enabled” instead of “Auto”. Getting this setting enabled will turn on the motherboard HDMI allowing everything to work. The setting should clearly specify that enabling will allow you to use integrated graphics for multiple displays.

  • Press Enter to confirm your changes.

When you restart your computer, exit and save these changes before booting back into Windows.

Step II: Connect your Display Device / Monitor


As soon as you enable the HDMI port on your motherboard, you will need to connect your monitor in order to use the HDMI connection on your motherboard. In order to connect your monitor, you will need an HDMI-to-HDMI cable. If your monitor doesn’t offer an HDMI input, using an adapter will do the task.

  • Connect your HDMI cable to the monitor.

Plug an HDMI cable into the HDMI port on the back of the video card to connect your primary monitor. If you have a secondary display, you should connect your primary display to your graphics card and the second display to your motherboard’s HDMI port. On your computer case’s bottom rear, there will be USB and graphics card ports located horizontally. In a standard computer, they are commonly found above the graphics card ports. Windows should automatically detect your monitors when you boot up. 

  • Display Settings

You can rearrange the monitors in the menu by clicking on Various Settings. Go ahead and play around with their Respective Display Settings. Select Display Settings from the right-click menu on your desktop. Make sure that all of the displays are configured correctly.

Step III: Always Install the Latest Integrated Graphics Driver

When you are unable to connect the secondary monitor, it is likely that the integrated card drivers are missing. The driver may need to be installed if the onboard Intel CPU graphics do not display under Windows when the ‘CPU Graphics Multi-Monitor’ setting is enabled in the BIOS.  

Make sure you have the latest graphics card drivers installed to enable HDMI on the motherboard. Under ‘Other devices’, it will be displayed as an unidentified device if the driver is not installed. The latest integrated graphics cards are very easy to update. They do not require any software downloads. 

To install the latest integrated graphics driver, follow the steps given below:

  • Navigate to Control Panel > Device Manager. 
  • Click on “Display Adapter.”
  • Check to see if there is an integrated GPU.
  • The Unidentified Device section under “Other Devices” will show it if it is not shown here.
  • Devices that have not been identified can be found under the Other devices section. There may be more than one. 
  • Download the latest driver from the Manufacturer’s website to ensure compatibility, or allow Windows to look for the latest driver on its own.
  • The second monitor should be detected after restarting your computer.

Benefits of Using Motherboard HDMI

Single Cable: The combination of audio, video and control information is carried by a single cable. Implementing such a system is easier due to the simple working of the cable.

More than One display: HDMI is best used on motherboards because it allows you to link multiple displays. If your graphics card does not have a second HDMI port or if both HDMI ports are complete, you should connect the monitor to the motherboard. Your workflow will become faster, your performance will improve, multitasking will become easier, and so much more. 

Higher Quality: With HDMI, your video will be transmitted loss-free and at higher resolutions and low brightness. Since there is no conversion, the resulting video quality is significantly better than that of the other counterparts. In addition, text and other details with high contrast are displayed much more clearly. 


For connecting other monitors, you can follow the above steps, which are easy and comprehensive to follow. There is no need to jack up the motherboard HDMI port. If you have a CPU that has a GPU, you can usually just enable integrated graphics through BIOS. 

It is most likely the old driver that is causing the issue if it does not work right away. If you follow all of the steps above, updating the integrated graphics driver will be easy and straightforward. As each generation of HDMI evolves, it becomes more and more compatible with consumers. Each year, there are constantly new features being added to the standard for manufacturers to implement if they desire. Manufacturers have the option to select which of the standard’s features are appropriate for their product line based on the HDMI specification. You will notice that HDMI is becoming a more standard connection option as you upgrade and purchase audio and video components.
