Overview

This USB to HDMI® Dual Monitor adapter lets you add two independent HDMI displays to your computer using a single USB 3.0 port. One of the HDMI ports can output resolutions up to 4K, while the other can output resolutions up to 1920 x 1200.

Increases your productivity by providing multiple displays

Adding more displays to your workstation can be difficult, especially if your computer does not support MST or offer many external video ports. This USB to dual HDMI adapter features two video outputs, boosting your productivity by giving you more screen space to work from. With multiple displays you have the freedom to access multiple applications at the same time and reference material on one display while you compose on the other.

Maximizes your screen real estate with resolutions up to 4K

One of the ports on this USB video adapter supports resolutions up to 4K at 30Hz, meaning you can connect a 4K monitor, HDTV,  or projector to your computer, even if your laptop or desktop video card doesn’t natively support 4K output. The USB to HDMI 4K adapter lets you extend or mirror your primary display onto an Ultra HD monitor or television, giving you the additional screen space you need to simplify multitasking and maximize your productivity.

Perfect for all of your business applications with USB 3.0 performance

Using the high-bandwidth USB 3.0 interface, this USB 3.0 to HDMI adapter enables smoother scrolling through documents, higher resolutions and better overall performance than earlier USB adapters. This video adapter is intended to support all of your business applications including web browsing, e-mail, spreadsheets and presentations. You can also leave your system video card available for more demanding applications such as gaming or CAD design, while you use the USB monitors for reference material.

The USB32HD2 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

(5 stars) Small and few wires. Great for on the road

By:
I’ve been using this as a dock for the rare time i work from home, i can plug my two home PC monitors into my work laptop without a lot of wires. Nice to have the big screens to work on at home. I received this product in exchange for an unbiased review.

(5 stars) Works Exactly as Desired

By:
Purchased this to add a second monitor to my HP Envy All-In-One system. I use this computer for work at home and needed another display. Setup was easy. The only variation from the directions was related to the USB Video Adapter Icon. I do not have an icon displayed on my System Tray. I viewed Devices, right-clicked the monitor, and edited the settings. Was able to switch the monitor order as desired. Everything is working as expected.

(5 stars) Easy and small

By:
This adaptor is an awesome plug and play, very easy to setup under Windows 10 and I use it for demo presentations when I'm on the road to visit prospective clients. The quality of the image is great and I didn't experience any freezing or delays. The adaptor itself comes in a small box and fits on my ultrabook bag. The instructions are well explained but I doubt you will need it. I haven't tried it on a MAC but for Windows users, it is a GO! "I received this product in exchange for an unbiased review"

(5 stars) Awesome Dongle

By:
I have used this USB to HDMI adaptor with several computers and it always connects and works well. The adaptor comes in a box about the size of three DVD cases. The adaptor's size is slightly smaller than the palm of my hand. The cable coming out is about a foot long and very flexible. It comes with instructions but I don't think they are needed as you just have to plug it in to start using it. When I connect this device to a new computer it takes about 30 seconds to detect, install and start working. Future connections only take seconds before it is working. The response time is very quick for the display and I can't notice any lagging. Only one port works with 4K, but I can use both ports with 1080p displays. I like the fact that I can connect this to any computer and I don't have to worry about what type of video out port the computer has. This adaptor works consistently well and quickly. I received this product in exchange for an unbiased review.

(5 stars) USB to Dual HDMI with no external power source!

By:
Wow! No external power source required when I connect two HDMI displays through a single USB port on my laptop. This is amazing! The picture quality is great and does not take up too much room in my bag when I am on the road. This is fantastic for the mobile worker or for sales presentations.

(5 stars) Great adapter.

By:
This adapter is great for connecting to 2 HDMI monitors. One in 4K HDMI and one HDMI (it’s hard to see, but it’s identified under each port) The adapter installs on its own (Win10) and works perfectly each time. I’m very impressed with the quality of the video signal from an adapter so portable, and without having to mess with drivers! I received this product in exchange for an unbiased review

(5 stars) Easy installation, great picture, just awesome

By:
Installation of this was so easy. Plugged it in and Windows 10 did its thing and instantly installed the video and audio driver for this device and voila it was up on the screen. Startech gives you instructions for getting this device to work but I did not need them, it just worked. The image quality was good and there was no latency issued that I experienced for basic work. Great little product !

By:
I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use.

Both displays I connected had exceptional picture quality, without tearing or pixalization during fast motion video. This unit provides smoother scrolling, higher resolutions and better overall performance than other USB adapters I have tested.
