Why Motherboard HDMI Not Working? Best Information In 2023

Motherboard HDMI not working is a common issue of not having the display you want when you construct or buy a new computer and connect your display into an HDMI port. The issue could be present when PC builders are experienced builders, as the different hardware components are built using different settings. Sometimes the problem goes beyond. Most likely, the HDMI port on the motherboard fails or appears to be inoperable due to a variety of causes. The most common causes are:

  • No integrated graphics are present in the processor.
  • Monitor input is checked from the menu.
  • The incorrect HDMI port.
  • Cables or ports that are not working.
  • Monitor not working.

How To Fix Motherboard HDMI No Signal?

Once you are aware of the reason for this issue and where it could be the source, let’s talk about how to eliminate this irritating issue. I’ve provided five easy solutions that can solve your issue without difficulty. Before we move on to the actual details I want to remind you that you need to ensure that your computer has an embedded graphics card sometimes referred to an GPU.

The reason is because motherboards do not have the ability to process video files by themselves. Actually, every video output port that is located on your motherboard gets power from the integrated graphics card of the CPU. If you own the Intel motherboard, then you likely have this feature , but a few motherboards do not have this feature. Check these steps to determine whether you’ve got an embedded GPU. Start the Start menu.

Find Device Manager, then click the result that appears first. Click on the Display Adaptors option to increase it. You’re free to continue with the fix If you find the GPU here. If you aren’t seeing anything that you can’t see, then upgrade your processor to one that is integrated with a GPU.

If you’ve identified the most frequent causes of HDMI not working is that it’s time to work on them one-by-one. Each piece of hardware is constructed in a different way, so it’s crucial to be aware of how you will deal with each problem.

No Integrated Graphics

If you’ve purchased an un-integrated processor, or one that does not have integrated graphics and display outputs, then the display outputs from your motherboard will work with HDMI. If you’ve bought an unsupported processor, or one that does not have an embedded GPU you’ll need an exclusive GPU in order to turn the display to work.

Processors in the latest generation series manufactured by AMD and Intel will come with various designations that let you determine if you’ve got an integrated graphics card or no. We’ve compiled a complete listing of AMD Ryzen processors equipped with an integrated GPU If your processor isn’t in the list.

The list, then you must purchase an appropriate graphics card. In the same way similarly, any Intel processor that was built in the past 5-6 generations that have an ‘F’ as their model’s name won’t come with an internal GPU.

Monitor Input

Most monitors automatically detect the connected cable and appear on the screen instantly. Certain monitors don’t. If your monitor isn’t auto-detecting, try to do it by hand. Monitors have a menu button on the border to the right of the bottom. You can then select an input tab, then choose HDMI. You could also try this by first turning off and on your monitor.

Using HDMI Port Incorrectly

If you’ve installed an video card into your PC, make sure that you’ve connected the HDMI cable directly to the HDMI port on the video card, not to the motherboard, as it’s by default turned off when the video cards is connected. To enable the Motherboard HDMI not working function again it is necessary remove from the video card.

Bad Port Or Cable

If you have an extra HDMI cable, you need to check if it allows the display to function. In the event that it doesn’t, the HDMI port on your motherboard or the monitor is damaged. If this is the case take your monitor or motherboard to the manufacturer to request RMA in the event that it’s in warranty.

If the warranty has expiring, your only option is to have your motherboard’s or monitor port examined. This requires chip-level expertise for repair the port, something that most people cannot accomplish. This is why it’s advised to have the port replaced or repaired by a specialist in computer chip technology.

You can also test a different monitor or motherboard one at a time to determine whether the display is working. This will indicate the problem with the port whether on the motherboard or monitor without having them all examined by a computer shop.

Faulty Monitor

Sometimes, replacing or repairing the HDMI port isn’t enough. A defective monitor could be the cause and in this scenario the other ports, including HDMI is able to function. It occurred to me with the Acer Predator X34 and you have to take it to a service center to fix it.

Why Is My Motherboard’s HDMI Isn’t Working?

Your motherboard HDMI could be experiencing problems because of a range of causes. One reason may be due to the fact that you’ve not turned on the CPU’s onboard HDMI graphics output in the BIOS. Also, you must ensure that the cable is securely connected to the ports.

Don’t have to be concerned for too long. This exact problem happened to me last year , and I tried various approaches before finding the best solution. I’ll make it simpler for you by discussing solutions that will work. So, without further delay you can grab a cup of coffee, and do not skip any part of going through this post.

Can You Use Motherboard HDMI With Graphics Card?

Absolutely, you’ll be able to accomplish this through the ports you can access on your GPU. Remember the fact that your GPU has a display port , and an DVI port, so the second monitor you choose to use should also have these ports. But don’t fret, if happen to have an LCD that isn’t equipped with these ports, or you prefer to use the TV you have, then you can use utilize the HDMI port on.

The devices that have GPUs by connecting the display port with an HDMI cable. Another crucial thing to consider to keep in mind is that the BIOS of your motherboard must fully support the possibility of having multiple displays at once when you intend to run two displays simultaneously.

Certain motherboards automatically enable this feature, but you must be sure to check whether it’s turned on in BIOS. The option I’m talking about can be found within BIOS and allows multi-monitor support on your motherboard. Simply visit the BIOS settings and select the option of onboard video under the graphics configuration. Note that activating this can result in a little less performance, based on your motherboard.

Why Do I Have A Secondary HDMI Connection Not Functioning?

This could be because you’ve not updated your drivers for a while, or because of a few missing Windows Updates. Go to the Updates section of your settings and download the most recent update.

Which Is Better? HDMI Instead Of DisplayPort?

Both are great for various reasons. DisplayPort is certainly superior because of its support for higher bandwidth . However, HDMI is more popularly used since it’s supported by many more devices.
