HDMI or high definition multimedia interface is an audio / video interface that can be used to interconnect multiple multimedia devices. The most common use is to connect the CPU to the monitor and projector. It can also be used to connect Blu-ray players and laptops to televisions or monitors. The main advantage it provides is that it has a single connection and can transmit audio and video with high quality such as 4K. But if you find that after connecting to the device using this port, the screen appears black and there is no audio output, then here are some things you need to see.

The HDMI port is not working properly

Various hardware failures can cause HDMI connectivity problems, but the exact cause is difficult to determine. When a connection is established using a device running windows 10, the following possible fixes are performed to resolve this issue:

-- physical inspection of hardware.

-troubleshooting using hardware and video playback

Update, roll back or disable the graphics driver.

-Miscellaneous repairs.

If you prefer to create system restore points, you can try to undo any changes to your computer by performing system restore. It is also recommended that you perform the tasks mentioned below only in safe mode.

1. Check hardware physics

You can try to dust off components, such as your computer's graphics card. I suggest using a small blower or wiping the components with a soft cloth. When performing this task, make sure that you do not damage any wet parts or cause damage to any circuits. Check to see if it is physically damaged.

Make sure you do this very carefully. Because even a slight bruise can cause your computer to stop working and may result in your financial expenses. If you are not confident, you can ask a qualified technician to do this for you.

two。 Troubleshoot using hardware and video playback

First open the Windows settings application. Navigate to the following path: updates and Security > troubleshooting.

Select the option named Video playback.

Then click the button named Run the Troubleshooter.

Follow the on-screen instructions to check that the problem has been resolved.

You can also run the hardware troubleshooter.

3. Update, roll back, or disable graphics driver

You need to update or roll back the driver. If you have just updated any drivers, then the problem begins, and you need to roll back the drivers. If you don't, it will be helpful to update the graphics device driver to its version.

From the WinX menu, open device Manager. Select the driver, and then right-click to open Properties. Next, switch to the Driver section. Rollback can be used only when it is updated. If this is not the case, click Update driver and Windows will automatically check for problems.

This error is usually caused by drivers related to the graphics drivers listed under the display adapter section.

4. Reset the monitor

You can also try to reset the TV or monitor using its hardware key and check to see if it can solve your problem. For more information, see the TV or monitor guide. This is because it varies by product type and product type as well as by manufacturer.
