Why Does The HDMI Port Not Work? How To Fix It
Sometimes the HDMI port may not work properly. This article will detail the common reasons why HDMI ports do not work and the corresponding solutions to help you solve this problem.
1. Check The Physical Connection
First, make sure the physical connection of the HDMI port is normal:
Make sure the HDMI cable is firmly inserted into the HDMI port of the device. Sometimes, a loose connection may result in unstable signal transmission or complete interruption.
If possible, try using another HDMI cable to rule out the possibility of a damaged cable. Poor quality or damaged cables may cause signal transmission problems.
2. Update The Driver
Driver issues are one of the common reasons why the HDMI port does not work properly. You can update the relevant driver by the following methods. We recommend using Driver Sentry for automatic driver updates, saving time and avoiding the risk of downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
After the scan is complete, it will show which drivers are missing or need updates. Find the drivers to update in the list and click the "Upgrade" button.
After the update is complete, it is recommended to restart the computer to ensure the updated drivers take effect.
3. Check The Device Settings
Incorrect device settings may also cause the HDMI port to not work properly:
Make sure the TV or monitor is set to receive signals from the HDMI port. The correct input source (e.g. HDMI 1, HDMI 2, etc.) can usually be selected via the remote control or device buttons.
When the computer is connected to the TV or monitor, the resolution setting is too high which may cause signal transmission failure. Adjust the resolution to the resolution supported by the monitor in the display settings of the computer.
4. Check The HDMI Port
Sometimes the HDMI port itself may be faulty:
Connect the HDMI cable to another device (such as another computer or DVD player) and check if it works properly. If the other device works, the problem is with the original device's HDMI port.
If the device has more than one HDMI port, try using the other ports to see if that solves the problem.
5. Reboot The Device
Restarting the device can solve many temporary problems:
Power off the computer and display device, wait a few seconds and then restart.
6. Check System Settings
Certain system settings may affect the proper functioning of the HDMI port:
Make sure your computer's audio output settings are correct. In Windows, right-click on the volume icon in the taskbar, select "Open Sound settings", and make sure the HDMI output device is selected.
In Windows, right-click on the blank space on the desktop and select "Display Settings", make sure the correct monitor and resolution are selected.
7. Update BIOS
An outdated BIOS may cause the system to fail to recognize the HDMI port correctly:
Visit the motherboard manufacturer's official website to download and install the latest BIOS update. Follow the instructions and reboot your computer after the update is complete.
Above are the reasons and solutions for HDMI port not working, hope it will help you.
