There are many situation when enabling the HDMI port on the motherboard may come in handy. Situation such as where you have limited ports on your dedicated graphics card, or if the HDMI port on the graphics card is damaged may warrant the use of motherboard HDMI port. Here we talk about how to enable motherboard HDMI.
Essentially enabling motherboard HDMI involves checking whether your CPU has integrated graphics or not. If yes, then you need to go into your computer’s BIOS and enable integrated graphics usually found in the Advanced settings with the name IGPU Multi-Monitor. Save your settings and reboot your PC followed by connecting the monitors and installing the latest integrated graphics driver.
You can see that on some motherboards with a discrete GPU, the integrated graphics is disabled in the BIOS by some manufacturers. However, users can easily enable it to get the onboard HDMI working also.
It should be noted that not all motherboards, particularly very old systems, support the usage of onboard video ports when you have a dedicated graphics card installed. In other words that many motherboard permanently disable the motherboard HDMI if you have the graphics card installed in the PCIe slots.
Therefore, you will need to do some inspection in the BIOS or in the manual of your motherboard to confirm whether it supports onboard graphics along side dedicated graphics.
Once you have confirmed, then the steps below will help you to enable the motherboard HDMI.
How to Enable Motherboard HDMI?
Ideally if you have a dedicated graphics card, all of your displays should be connected to it. However, in case where the use of motherboard HDMI is warranted you can review the following steps:
There are 4 major steps basically:
- Check for Integrated Graphics in Your CPU
- Enable Integrated Graphic in BIOS
- Connect Your Monitor
- Install Latest Integrated Graphics Driver (if necessary)
Step 1: Check for Integrated Graphics in Your CPU
The first thing you need to do is to make sure that your CPU has integrated graphics. The reason is that the HDMI port on your motherboard runs from the integrated graphics and not your GPU.
For this, you can open “Settings” in Windows 10. Select “System” and then “About”. Look for the the processor model here. Do a quick google search of your processor model number in Google and check whether it has integrated graphics in the tech sheet.
Another method is to right click “This PC” and go to “Properties”. This too will tell you the processor model which you can look up online for IGPU specs.
Alternatively, you can also access “Device Manager” and head over to the “Display Adapter” drop down section to check if you have integrated graphics.
Only a Limited AMD CPUs have Integrated Graphics
While most of the Intel processor come equipped with integrated graphics, the same is not true for AMD CPUs.
Only a select few AMD processors that have a “G” designation come equipped with one. Hence in order to use motherboard HDMI port on an AMD system, you will need to have a “G” designated CPU such as the AMD Ryzen 3 3200G.

Step 2: Enable Integrated Graphics in BIOS
Once you have confirmed that your CPU supports IGP, then follow these step:
- Go in the BIOS and turn on the integrated graphics. For this purpose, save all your work and then restart your computer.
- Then press the key the moment the computer reboots to bring up the BIOS. Common keys for this task include the Escape, Delete, F1, F2, F8, or F12. You can search for or consult your motherboard’s manual to find out the specific key if you are unsure about it.
- You must be very careful while navigating through the BIOS because you do not want to accidentally change important settings. The BIOS may look different for different motherboard models.
- Look for the Advanced tab or section.
- In the section of Advanced settings, look for settings related to IGPU, multiple display.
- If this setting is disabled, change it to enabled. Enabling this setting would turn on the motherboard HDMI.
- Save your changes and press Enter to confirm.
- Restarting your computer will make all the necessary changes.
Step 3: Connect Your Monitor
- Plugin your primary monitor to the HDMI port on the back of the video card. Next plugin your secondary monitor to the HDMI port on the motherboard.
- Plug the other end of the HDMI cables into the respective monitors.
- When you boot into Windows your monitors are detected. You may want to correctly configure the displays. For this right-click on your Desktop and choose Display Settings.
- In the menu, you can adjust various settings related to the monitors such as rearranging them.
Step 4: Install the Latest Integrated Graphics Driver
In case if the secondary monitor is not detected, the driver for the onboard graphics may not be installed or can be outdated. For this perform the following steps:
- Open Device Manager in Windows. Under the section Other devices, look for an unidentified device.
- Install the latest driver from the download website of your CPU manufacturer or let Windows automatically search for the appropriate driver.
- Restart your computer and then wait for the secondary monitor to be detected.
You can also use Window native “Check for Updates” feature to find the latest drivers for the integrated graphics.

Why Enable Motherboard HDMI?
The biggest advantage of enabling motherboard HDMI is that it allow you to connect extra monitors to your system.
Most motherboards come with one HDMI port. On the other hand, if you do have a GPU installed, then depending upon its age and model, you can have just a single or multiple HDMI ports on it.
If you have an older GPU, or if the HDMI port on your GPU is damaged, then the onboard motherboard HDMI can come in quite handy particularly for connecting multiple displays.

When performing the method as to how to enable motherboard HMDI, pay attention to the number of monitors you need to set up. If your GPU has multiple HDMI ports and it’s enough for your needs, then its best to connect these monitors to these ports. You can enable onboard HDMI to connect extra monitors.
Though you can set up multiple monitors using HMDI ports on both your GPU and motherboard, you may experience some lag and drop in performance especially when you move windows between your monitors.
We recommend that connecting a monitor to HDMI port on GPU and another to HDMI on the motherboard may just be adequate for most people.
