USB-to-HDMI adapters allow users to connect desktop or laptop computers to additional display devices via HDMI, even if the device does not have an HDMI port.
However, the USB-to-HDMI adapter doesn’t always work for some Windows 10 users. Some have even written on the Microsoft forum that their USB-to-HDMI adapters don’t work.
Why don’t USB-to-HDMI adapters work?
There are different types of USB-HDMI adapters and docking stations. Additionally, Windows is constantly providing updates to the drivers installed on the devices. However, because of these updates, compatibility settings may not match. Some older adapters and docking stations may not work with certain devices. The same is true in the other direction, as some new adapters may not work with some older drivers.
How to troubleshoot a non-functioning USB-HDMI adapter?
Check the version of your operating system
Some people forget to check if their operating system is compatible with the adapters they just bought. If this is the case, you should first determine the version of your operating system.
Windows operating system:
- On your keyboard, press the Windows logo key and R at the same time to bring up the Run window.
- Type msinfo32 and click OK.
- The System Information window opens. Click System Summary in the left pane, and you’ll see basic information about your PC in the right pane.
- Find the Operating System Name entry that indicates the version of your system. For example, Windows 10 Pro.
Mac operating system:
- Click on the Apple icon in the upper-left corner of your computer screen. Then select About this Mac.
- In the window that opens, you’ll see the exact version of your Mac’s operating system.
Now that you know the version of your operating system, it’s time to determine if it will work with your USB-HDMI adapter. Some adapters only support certain versions of operating systems. If you have verified that there is no problem between your computer and the adapter, move on to the next solution.
Download and install the latest driver
Your USB-to-HDMI adapter may also stop working if the appropriate driver has not been installed correctly. In this case, you should immediately try to download and install the latest driver.
You can download the driver manually from your adapter manufacturer’s website (the website is often listed in the user manual). Then install the driver and restart your computer for the changes to take effect. It is best to remove the adapter from the computer during the reboot.
If you don’t have the time, patience, or computer skills to manually update the adapter driver, you can also do it automatically with a third-party driver update program.
A third-party driver update program automatically detects your system and finds the right drivers for it. You don’t need to know exactly what system is installed on your computer, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry that you’ll make a mistake during installation. Driver Easy takes care of everything.
Check your USB connection
Your USB port may have stopped responding, which means that the connection between your two devices has also stopped working. Check the USB port and make sure it is working properly. If not, you need to connect the adapter to a different port.
