Use Motherboard Video Output with GPU

Use Motherboard Video Output with GPUWhen you install a graphics card on your PC, the video output on the motherboard is usually deactivated. Multiple displays necessitate the use of the motherboard’s Video Output connector. 

Fortunately, there is a solution to get around this problem using BIOS. However, there are a few crucial points and components of your system that you must examine before enabling the motherboard’s Video Output. 

Originally, the CPU was utilized for graphics and video editing. Nonetheless, when new inventions entered the market, demand for a more demanding and high-profile processor developed, leading to the birth of GPUs.

GPUs were developed to relieve CPUs of these tasks while simultaneously boosting 3D graphics rendering. GPUs employ parallel processing, a technique in which many processors tackle various portions of the same activity. 

The adoption of GPU greatly improved the quality of gaming experience and graphic rendering, and GPU became even more popular.

In this article, we’ll go through how to use motherboard HDMI with a graphics card connected in.

Your CPU must have an Integrated GPU:

So, before we even discuss activating the motherboard’s HDMI connector, you need to ensure that your CPU has an integrated graphics card. If your CPU lacks an integrated graphics card, your motherboard’s HDMI connector will not function. 

This is due to the lack of an inbuilt video processing chip on motherboards. All of the visual output ports on the motherboard’s rear I/O panel are powered by the CPU’s integrated graphics card. Unfortunately, some CPU models lack an iGPU, so you should be aware of this.

How the Graphics Card works:

A CPU is a physical component that helps communicate with various apps and programs that have been downloaded into the PC; it also governs the system. GPUs and CPUs are built in very similar ways. 

A GPU can be located on a graphics card, a personal computer’s motherboard, or on the same electrical circuit as a CPU. GPUs, on the other hand, are designed to do more rigorous arithmetic and geometric computations. 

Specific computations are required to produce graphics, and the GPU has all of the necessary operations for smooth pixels and other video editing and graphic pictures. A GPU may contain more cells than a CPU.

How to Check if your Motherboard has an Integrated GPU:

There are two ways to determine whether or not your CPU has a GPU:

  1. Read the official specifications documents
  2. Internally, check the operating system (Device Manager)

1)Official Specifications:

This procedure is quite simple. If you know the manufacturer and model of your CPU, you can look up its spec-sheet online. 

The following snippet from Intel’s website, for example, gives the Processor Graphics information for the Intel Core i7-11700K CPU. The Intel UHD 750 GPU is built into this CPU.

2)Through Device Manager:

Another simple option is to use the “Device Manager” tool to verify. 

  1. To accomplish this, go to the Windows Taskbar and search for “Device Manager.” (You may also open Device Manager from the Control Panel.)
  2. In the new window, expand “Display Adapters” and look at the GPUs it shows.

If you notice another iGPU beside your Dedicated Video Card, this is confirmation that you have an integrated graphics card capable of supporting the motherboard’s HDMI connections.

If your Display Adapters section does not have an iGPU, the motherboard Video Output ports will not function.

After you’ve confirmed that your CPU has an integrated graphics design system, the following step is to enable the motherboard HDMI from the BIOS:

  1. First, enter the BIOS; when your system boots, press the right key to enter the BIOS. The particular key for entering the BIOS on a PC may differ. The keys “Delete” and “F12” are commonly used.
  2. Look for a section linked to the IGPU and display; once in the BIOS, look for the manual settings that make changes in IGPU; all you need to do is enable the IGPU. Because of differences in BIOS, the settings may differ. For some, it may say “Enable Multi-GPU Support,” for others, “Enable IGPU,” and so on.
  3. You should save the changes you’ve made.
  4. Now connect your monitor to the motherboard’s HDMI port; attach your second monitor to the motherboard’s HDMI port, and you should be ready to go. It would be advantageous if you now have a functional HDMI port on your motherboard.
  5. You may also tweak the multi-monitor display settings. The angle, resolution, and display may all be simply changed. It is possible to alter it in your PC’s display settings. Several additional parameters may be altered manually as well. The same method is used to change the brightness and other font settings; right-click your way to the desktop, and a pop-up opens; pick the display settings, and then perform whatever modification you desire. 


So, the solution to the query “how to use motherboard HDMI with graphics card” is dependent on your replies to two additional questions:

  • Do you have a CPU that has an iGPU?
  • Is your BIOS equipped with the necessary settings and controls to enable GPU?

If you answered yes to the questions about your PC, you won’t have any trouble using the motherboard video output with GPU. The connection of the motherboard HDMI port is simple and does not necessitate any difficult or sophisticated processes. 

Simply change a few settings in your BIOS, and you’re ready to go. The usage of GPU has shown to be beneficial in video editing and rendering of visual material with fast processing and a customer-friendly experience.

It’s also worth mentioning that enabling the iGPU to power video ports on the motherboard in BIOS not only enables the Video Output but also any additional ports that your motherboard may have. 

If your motherboard additionally includes a VGA, DVI-D, or Display Port, those will be activated as well.
