How to Install a USB to HDMI Adapter and Add an Extra HDMI Port to Any Desktop or Laptop PC
A USB to HDMI display adapter allows you to connect an additional monitor, TV, or projector to your Windows desktop or laptop even if there are no available HDMI ports. These adapters connect through a USB 3.0, USB-A, USB-C, or Thunderbolt port and create an additional video output for a second or third display.
What You'll Need
USB to HDMI adapter
HDMI cable
HDMI monitor, TV, or projector
Available USB 3.0, USB-C, or Thunderbolt port
Internet connection for driver installation if needed
Step 1: Connect the USB to HDMI Adapter
Turn on your desktop or laptop.
Plug the USB to HDMI adapter into an available USB port.
Connect the HDMI cable to the adapter.
Connect the other end of the HDMI cable to your monitor or TV.
Turn on the monitor if it is not already powered on.
Step 2: Install Drivers for Display Link
Many USB to HDMI adapters use DisplayLink or similar display technologies.
Wait for Windows to automatically detect the adapter.
If drivers do not install automatically:
Install the drivers included with the adapter.
Download the latest drivers from the manufacturer's website.
Restart the computer if prompted.
Step 3: Set Up the Additional Display
Windows 11

Common Problems and Fixes

Tips
USB 3.0 adapters generally perform much better than USB 2.0 adapters.
Many adapters support Full HD 1080p, while newer models support 4K.
USB to HDMI adapters are excellent for office work, web browsing, spreadsheets, video playback, and adding more screen space.
For gaming or high-refresh-rate monitors, a direct HDMI or DisplayPort connection from the graphics card is usually the better option.
