A common problem that many people encounter is that when trying to extend the display, usually you only have one HDMI port on your graphics processing unit (GPU). When you plug your second or third monitor into the HDMI port on the motherboard, it doesn’t work. So, you may ponder: how to enable motherboard HDMI?
Basically, that will involve 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.
How to Enable Motherboard HDMI?
When setting up multiple monitors especially in desktop computers, most people will like to enable motherboard HDMI as well. This allows for using HDMI connectors on both the GPU and motherboard for successfully setting up all the monitors.
There are 4 Major Steps
- Check for Integrated Graphics in Your CPU
- Enable Integrated Graphic in BIOS
- Connect Your Monitor
- Install Latest Integrated Graphics Driver
Here’s the method to enable onboard HMDI as well as setting up multiple displays in Windows.
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”.
- Check the model of your CPU that is given beside the processor.
- Do a Google search for the name and model number of this CPU. Then open the web page that mentions the specifications of the CPU.
- Look for the “Processor Graphics” section and confirm that the CPU has integrated graphics.
Step 2: Enable Integrated Graphics in BIOS
- Now you need to 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.
- Then the computer’s BIOS will open. You must be very careful while pressing something as it could cause damage to your computer. The BIOS may look different for different motherboard models.
- Look for the Advanced tab or section. Select it and press Enter. You may need to reconfirm to enter the section.
- In the section of Advanced settings, look for System Agent Configuration. Enter it and then select Graphics Configuration.
- Look for a setting named Enable IGPU, Integrated Graphics, or IGPU Multi-Monitor. It may already be set as disabled.
- Enable this setting that would turn on the motherboard HDMI. After you have done that save your changes and press Enter to confirm.
- Restarting your computer will make sure the changes take effect.
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. 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.
What is HDMI and Why it’s Significant for a Computer?
Essentially, HDMI stands for High Definition Multimedia Interface. It’s a cable and connector that is capable to transmit high-quality video and audio between devices. The point to note here is that HDMI is a digital connection and a single HDMI cable carries audio and video stream together.
It also produces the best quality picture and sound compared to other types of connections such as DVI or VGA. Today HDMI has become the standard interface for the connection of audio-visual devices. It is widely used in computers also, which includes both desktops and laptops.
You will usually find them on the motherboard and video card (also known as the GPU) on the back of the computer. It’s important to note here that not all video cards and motherboards have HDMI ports.

Why Enable Motherboard HDMI?
The biggest advantage of enabling motherboard HDMI is that you can connect extra monitors to your system. This depends on the number of HDMI ports on both the motherboard as well as the GPU.
Most motherboards come with one or two HDMI ports. On the other hand, if you do have a GPU, you will probably have as many as one to three ports. This does not include the ports on the motherboard.
As you see having dual or multiple monitors in your setup bring several advantages. It leads to improved productivity, provides more immersive experience while watching videos and movies and is also beneficial for gaming.

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.
