Fixing USB to HDMI Adapter not Working

There may be different reasons for using a USB to HDMI adapter. This applies to all types of USB, such as Type C, USB-A, and Micro-USB. You can use the adapter to connect any laptop or computer to an external display. You can also use the adapter to connect some of the latest smartphones to external displays. Samsung offers such a feature called DeX, which provides a desktop experience on new devices when connected to an external display.

However, problems can arise when using this external hardware. There have been reports of adapter users working with one port and not the other. There have also been reports of adapters working on one device but not the other. Here we will try to suggest solutions to these problems.

Update or reset Windows

Windows 10 has been an issue for a long time. There are unprecedented problems with each new update. The update also can’t be turned off, so you’ll need to update at some point. Users have reported that the adapters work before the Windows 10 update. The problem is solved by updating to the latest version or upgrading to a previous version. Resetting Windows Update only works if you’ve updated Windows 10 in the last 10 days.
Here’s how to restore Windows 10 update to your computer:

  • Press Windows Key + I. Click “Updates and security.”
  • Click the “Restore” tab and click the “Start” button under “Back to an earlier version.”

To update Windows 10 to the latest version, follow these steps:

  • Press Windows Key + I. Click “Updates and security” (as before).
  • Click the Windows Update Center tab, then click Check for updates.

After installing the updates, restart your computer and make sure the adapter is working properly.

Connect the adapter to a different USB port

The problem may be related to the USB port to which you plug your USB-HDMI adapter. Therefore, try connecting the USB-HDMI adapter to a different port on your desktop or laptop computer.

Check your USB connection

Your USB port may have stopped responding, which also caused the connection between the two devices to fail. Check your USB port and make sure it’s working properly. If so, skip to the fix below. If not, you need to plug your adapter into a different port.

Check for hardware changes.

  • Right-click the Start button on Windows 10 to select Device Manager from the Win + X menu.
  • Select your computer in the Device Manager at the top.
  • Click “Action” to open this menu.
  • Select the Check for hardware changes option.
  • After scanning, try the USB-HDMI adapter.

Windows may detect a connected USB-HDMI adapter after checking for hardware changes.
