It’s normal for HDMI to be a plug-and-play type of display connection. When you attach your Windows 10 computer’s HDMI monitor, nothing happens.
There are a few things you may try if your HDMI ports don’t work in Windows 10.
1. Use a second outlet for a short period of time.
In order to make the following enhancements, you’ll need a screen that can display the available output. Other display outputs may be available on your graphics card.
Try it if you have a common port type between your TV and your graphics card. DisplayPort is better than HDMI, however it could be a temporary fix until you find a better answer for your problem.
You can use an adaptor if your monitor only has one HDMI input. A DVI, VGA, or display connector to HDMI adapter isn’t that pricey these days.
2. Examine the wires and ports for damage.
Before attempting anything more, make sure the HDMI ports on your computer and display are free of damage, such as corrosion or loosened plugs.
A damaged or partially broken connector or freezer on the wire should be avoided at all costs. In the event of any damage, it is best to replace or repair the affected components.
3. Try to make things better.
Mix and match the components in your HDMI connection with other devices to discover if the problem is with the display, computer, or cable itself. This will assist in identifying the problematic component.
4. Select the appropriate PC HDMI port.
The HDMI port is found on the motherboard of many desktop computers with built-in graphics. Make sure the HDMI cable is connected to the discrete GPU and not to the HDMI port on the motherboard
if you have one installed. A motherboard connector is depicted in the image above. Long slots on the rear of the machine will be used to access the card’s single GPU port.
Integrated and separate graphics cards can both be used simultaneously on some machines. You’ll find those choices in the BIOS / UEFI setup menu.
To make these adjustments, consult the handbook that came with your motherboard, as they can vary from one brand to the next.
5. Using the associated cable, restart the computer.
With the HDMI wire and display attached, restart your computer. When you connect it to your HDMI cable, Windows should automatically detect it.
However, this does not always happen. The screen is commonly detected if the computer is booted with everything installed.
6. Make sure you’re using the proper HDMI input.
HDMI inputs can be found on a wide range of monitors and televisions. Please make sure that the display is configured to use the HDMI input that you have connected to it.
If you don’t know how to use it, you’ll need to consult the handbook for your display.
7. In Windows, make sure you’re using the correct multimeter mode.
For dual monitor setups using HDMI displays, double-check that Windows is set to use the correct dual monitor mode. Choose one of the following:
Do not use more than one screen at once. Only make use of the second display. The desktop should be spread across both displays. Set both displays to display the same desktop image.
Holding down the Windows Key + P will allow you to swiftly move between different modes. Select your chosen mode by clicking on the mouse.
If you’re having trouble seeing anything on any screen, try holding down the Windows key while pressing P repeatedly.
8. Choose a resolution and refresh rate that are supported.
When you connect an HDMI monitor to your computer, your computer should automatically select the suitable resolution and refresh rate for the display.
Ideally, the screen should provide an error message stating that an unsupported resolution or refresh rate has been chosen. You may see nothing or perhaps a “no signal” notice in some instances.
To adjust the resolution and refresh rate of a secondary monitor, simply access the display settings menu on the primary display.
The name and configuration of the GPU utility varies depending on the brand of GPU you have. To get to these settings, simply right-click on the desktop and select Nvidia,
AMD, or Intel Utility from the context menu that appears. You’ll need to discover the display settings once you’re in the utility. For illustration’s sake, we’ve included a screenshot of our Nvidia Laptop GPU in action.
Your screen should now operate after making these modifications and exiting the settings window. If you’re utilizing an older or newer version of HDMI, your resolution and refresh rate may be restricted.
While our monitor can accomplish 2560×1440@165Hz via the display port, it can achieve only 144Hz over HDMI. As an example,
9. Video works fine, but no audio
HDMI is capable of delivering both video and audio, albeit only video may be audible. For this reason, Windows 10 doesn’t recognise your HDMI audio stream as a distinct sound source in Windows 10. This audio device can only be accessed by going to it.
Go to the notification section and tap on the speaker icon.
To see a list of available output devices, click the up arrow.
You can choose from a variety of options.
All noises will now be played on your HDMI device, which doubles as an audio device. Learn how to simultaneously play audio on headphones and speakers in Windows 10 for additional information on Windows 10’s audio routing.
10. Install the most recent version of Windows and the latest graphics card drivers.
The final step is to ensure that Windows and the GPU driver are both current.
Check for updates in the Start menu, search, and then open it to ensure that you’re running the most recent version of Windows 10. Any pending updates will be displayed when you click the Check for Updates button.
The best place to find the drivers for your GPU is on the website of the manufacturer of your GPU. You may be able to use a GPU utility tool currently installed on your computer to check for updates.
For more particular information, consult the documentation provided with your GPU.
Use the System File Checker.
System file corruption may be interfering with your graphics card’s performance, even though this is an extremely remote possibility.
System File Checker is the quickest and most straightforward way to make sure that all of your system files are intact.
Our SFC and DISM articles will teach you how to use SFC. In a matter of seconds, you’ll be able to fix the vast majority of corrupted system files.
High Definition Multimedia Interface (HDMI) ports are found on HDMI motherboards. High definition video and high-quality audio can be transmitted over a single HDMI connection.
To connect to several monitors and televisions, the motherboard computer does not require a separate audio cable.
Both desktop and laptop computers have HDMI motherboards, and many monitors and televisions have HDMI connectors as well.
As a result, a separate video or sound card isn’t always necessary with today’s motherboards. For budget laptops, this is especially true, as both space and cost can lead to integrated graphics.
HDMI and VGA ports can be found on a motherboard with integrated graphics, which is basically a motherboard with built-in video.
