Graphics cards come with at least one hdmi port so you can connect a monitor or projector to it. the latest graphics cards have more than one port for versatile connections.
The second hdmi port is useful when you want to connect a second monitor or a projector and a monitor. However, if your graphics card has only one hdmi port, then it can be quite a hassle to connect a secondary display device. still, it is not the end of the road.
Reading: How to connect hdmi to motherboard
You can use the hdmi port on the back of your motherboard. There are a few things to check before connecting your secondary monitor to the motherboard’s hdmi.
This is a quick DIY guide to help you enable your motherboard’s hdmi to connect another display device.
step 1: look for integrated graphics on your cpu
Before you enable hdmi on motherboard, please first check if your cpu has integrated graphics. the hdmi port on your motherboard is not running from the gpu, but from the integrated graphics. there are multiple methods to confirm this.
The easiest method is to go into device manager and check the display adapter menu to see if your cpu has integrated graphics.
another method is to find the processor model and get the information online. for this,
open settings and select system. then click about. you will be able to find the processor model. alternatively, you can right-click on my computer or this pc and select properties. here you can also see the processor model.
Using the model name, google to see if it has integrated graphics or not.
step 2: enable integrated graphics in bios
after confirming that your cpu has integrated graphics using any of the above methods, you need to enable it in the bios. To do this, follow the steps below,
restart your pc and press any of the keys: f1, f2, f8, f12, escape and delete. Doing this will open the bios. you will find the exact key in the manual of your motherboard
The bios interface will be different for different motherboard models. the bios contains all the important settings of your pc. therefore, you must be careful when navigating the bios screen so as not to unknowingly modify any other settings.
Locate the advanced tab or section in the bio.
now, search for igpu and multiple display configuration. make sure this setting is enabled. this will activate the hdmi of your motherboard.
After this, save the changes and press enter to confirm the new settings.
reboot your computer to activate the new settings.
Step 3: Connect to your new monitor
After you enable the hdmi on your motherboard, you can connect the monitor to the hdmi port. These are the steps to connect two monitors to the cpu.
first, connect the main monitor to the hdmi port located on the back of the video card. then connect the secondary monitor to the motherboard hdmi.
then connect the other end of the hdmi cables to the respective monitors. after making the connections, your pc will automatically detect the two monitors.
then you will need to configure the display settings. right-click anywhere on the desktop screen of your primary monitor and select display settings.
The display settings menu will open. you can configure the settings related to monitors as you like.
Step 4: Install the integrated graphics driver to its latest version
In some cases, the secondary monitor will not be detected even after enabling the motherboard hdmi and configuring the display settings correctly. The reason for this may be because the integrated graphics driver is not installed or is out of date. In such cases, you can install or update the driver by following the steps below,
Search for device manager in the windows search bar and open it. now, under the other devices section, look for an unidentified device.
then visit your cpu manufacturer’s website and download the latest drivers by searching using your cpu model. alternatively you can also let your pc search for the latest driver. the other option is to use the native windows check for updates feature to find and download the latest driver.
Once you have downloaded the driver, you can run setup and install the driver by following the on-screen instructions.
After this, restart your computer to save the changes. when the computer is turned on, the secondary monitor will be detected.
influence on performance of dedicated and integrated graphics
If you don’t have any free ports on your dedicated graphics card, you can use the motherboard’s hdmi port to connect an additional device. An integrated graphics solution uses a lot of power and memory with the GPU to display information. this causes a load on the cpu and system memory which can lead to high latency in apic timer interrupt transmissions.
Dedicated GPU can easily access image data using discrete graphics cards with memory. the same cannot be said for the integrated graphics. they cannot extract image data as they do not have a reliable memory pool. however, they use the device’s memory to extract the image data.
If you unplug the secondary monitor while gaming, it will increase the fps (frames per second). the integrated graphics will go into sleep mode. you can plug the monitor back in after your gaming session.
advantages of using hdmi motherboard
The most obvious benefit of using the hdmi motherboard is to connect multiple display devices. If your graphics card doesn’t have a second hdmi port or if both ports are used, then the motherboard hdmi can be useful to connect another monitor.
There are several advantages to using a second monitor. increases your work efficiency and productivity by allowing you to multitask.
When it comes to gaming, you can use one monitor for the game interface, while the other monitor can be used to track your hardware and ram usage. You can also browse online and open web pages containing game tips and tricks to give you an edge.
As most recent games come with high-end graphics, a single graphics card won’t hold up, forcing you to use two cards. in this case, a second monitor will speed up the phase allowing you to get slight performance effects. your pc will have more vram to support high resolution textures in games.
disadvantages of using hdmi motherboard
The main drawback of using the motherboard hdmi to connect a monitor is that you won’t be able to play multi-monitor games.
Also if you are not a gamer or using high end 3d software then using a second monitor with hdmi motherboard will not be the right choice. Instead, you can buy a motherboard that supports multiple graphics cards, including multi-card power supply.
