The motherboard’s HDMI connector might come in helpful in a variety of situations. Your graphics card might run out of HDMI ports, or if the port on the graphics card is broken, you might wish to enable the motherboard’s built-in HDMI.
Before we begin, please verify that your CPU is equipped with Integrated Graphics. If so, you may activate integrated graphics in your motherboard’s BIOS. Advanced options include a section titled IGPU Multi-Monitor, where this option may be found.
Then reboot your PC, connect the monitors, and install the newest integrated Graphics Driver to get the best performance.
Some motherboards, particularly older ones, don’t allow the use of onboard video ports when a dedicated graphics card is attached. This is something to keep in mind. To put it another way, if you have a Pie graphics card installed on your motherboard, the inbuilt HDMI option is disabled.
Because of this, you must check the BIOS or documentation of your motherboard to find out whether or not it supports Onboard Graphics with dedicated graphics.
You may wish to add an additional monitor to your system, but you won’t be able to since your video card only has so many HDMI connectors. One HDMI port is standard on most motherboards.
On the other hand, if you already have a graphics card installed, the number of HDMI ports it has will depend on its age and type. Onboard Motherboard HDMI is a lifesaver if you have an older GPU or if your GPU’s HDMI port has been broken.
We have now reached the Crucial Stage. There is no other option for you if you fail this stage. I’m afraid.
Because the HDMI connection on your motherboard is powered by your CPU’s integrated graphics rather than your GPU, you must ensure that you have a CPU with integrated graphics.
Click the “Display Adapters” menu in device management to do this Try to find out whether your machine has any integrated graphics other than the Pie graphics adapter that you’re now using.
As an alternative, you may type in your CPU model number into Google and see whether it has integrated graphics. Many Intel processors these days include integrated graphics, however the same cannot be true for AMD processors.
Only a small number of AMD Processors with the suffix “G” are equipped with this feature. The AMD Ryzen 3 3200G, for example, requires a CPU with the designation “G” in order to connect to a motherboard HDMI port.
Once you have confirmation of the fact that the CPU supports integrated graphics, follow the steps given below:
No sign of a second monitor? Update your integrated graphics driver if necessary.
It is totally safe to use an onboard HDMI slot, provided that your system allows integrated graphics.
If the GPU connected to the PCIe slot has 2 HDMI ports, you can utilize the onboard HDMI to connect upto 3 displays. However, keep in mind, that all the conditions discussed above should be met.
Most of the time when people turn to the option of using the Motherboard HDMI Slot, it is because they want to run multiple displays but have run out of ports on their GPU.
Many high-end GPUs these days come with 2 HDMI Ports. If your GPUs have multiple ports, then you don’t need to Consider The Option of the onboard HDMI slot.
