Review on 🔌 USB to Dual HDMI Adapter: Efficient Dual Display Solution for MacBook Pro/Air, Surface Pro/Go, Chromebook, Thinkpad/Yoga, etc. by Collin Jackson

For example, this device has 2 HDMI ports that support 60MHz. Has all the basic ports you're likely to need and is a great replacement for a much larger dock with a small profile and easy to carry too. The cable is a bit short, about 5 inches, so it's close to your laptop. Gets a little warm, but that's to be expected from any electronic device that actively transmits signals and power. When I connected my HP monitor, it found the device with no problems (via HDMI).
