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.

Frequently Asked Questions

Troubleshooting

  1. Our driver may not be installed or is out of date.  Install the latest driver from StarTech.com’s website.
  2. The primary display adapter for the computer has an outdated or basic driver installed. Update the video driver using the manufacturer’s support site.
  3. The product requires an existing video controller (onboard or discrete) from Intel, AMD, or NVIDIA.  The video controller must have a WDDM (Windows Display Driver Model), compatible driver. Most video controllers from 2008 or newer will meet this requirement.
  4. An incompatible operating system is being used (i.e., MCT based adapter and macOS).  If using a Mac, we recommend exchanging the product for a DisplayLink based version.
  5. The display connected to the StarTech.com adapter is set to the wrong video input. Use the display’s on-screen display menu to select the correct input.

Ensure the Sound Playback device in Windows (or Output device in macOS) has been set to be our USB audio device.

Touchscreen Monitors

A mixture of touchscreen and non-touchscreen displays can cause a conflict with your internal video card. Because of this limitation, touchscreen functions may be disabled when the USB Video Adapter is connected, or the USB Video Adapter may not work at all. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

All-in-One Computers

Many all-in-one computer systems limit the number of possible monitors to one. This is a limitation in how all-in-one computers are typically manufactured, so adding an external display may not be possible regardless of which USB video adapter is used. Contact the manufacturer of your system to confirm whether your specific model can support a secondary display or not.

If the display connected through your USB display adapter does not wake up after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. 

The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.

Note: You may need to disconnect and re-connect your USB display adapter after applying these settings to re-establish the connection.

Your user account may require administrator privileges to install the driver.  If the computer is managed by the IT department or service provider, they may need to be contacted to help with this step.

Disable hardware acceleration in each browser and Office application, then close and re-open each application.

Common Issues

Using the On-Screen Display menu for the display, enter the Menu system and go into “Picture Mode” then “Aspect ratio” and change from “16:9” to “Just scan” or “1:1 pixel mapping.”  The wording may vary depending on the manufacturer of the display.

Before You Buy

You may have heard of USB video adapters, and have been wondering what they are, and whether or not they will work in your setup.

USB video adapters are devices that take one USB port and go to one or many video connections, such as VGA, DVI, HDMI or DisplayPort.  This is useful if you would like to add an additional display to your computer setup, but are out of video connections on your computer. 

USB video adapters allow you to mirror or duplicate your display, so the same windows are shown on all of your displays, or extend your desktop, so that you can have different windows on each display.

So what do you need to know before you purchase a USB video adapter?

  • USB video adapters require the computer to have a free USB port.
  • Check which video connections your display has, and select the appropriate USB video adapter.
  • Ensure that the USB video adapter is compatible with your operating system.
  • USB video adapters require your video card to be able to handle an additional display.  This is because USB video adapters work with your onboard or dedicated video card to drive additional displays.  For this reason you are advised to confirm this with your video card manufacturer. 
  • Consider what you will be doing on the additional display.  If you are looking to perform less graphically intensive activities like using Microsoft Office, email, or basic web surfing, you can use any USB video adapter.  If you are looking to perform more graphically intensive activities like high end photo or video editing, you want a USB video adapter with dedicated memory. 

There are a few other important things to note:

  • When using multiple USB video adapters on the same computer, they need to use the same chipset family.  For example, MCT/Trigger, DisplayLink or Fresco.  Note: How many adapters you can use depends on the SKU.
  • You may not be able to use a USB video adapter with an All-In-One computer.  These computers are almost always hardwired to only accept a single display.
  • You may not be able to use a USB video adapter with a touchscreen computer or display.  A mixture of touchscreen and non-touchscreen devices can conflict with the video card. 
  • You should not use a USB video adapter to play video games.  They are not designed for use with video games, and their performance with them is poor at best.

USB to Dual HDMI Adapter Made Easy

By: jhuber123456 - 06/24/2017
I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use. This unit lets you add two independent HDMI displays to your computer using a single USB 3.0 port. 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.

Easy installation, great picture, just awesome

By: Macphoto - 07/13/2017
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 !

Great adapter.

By: Andrew11 - 07/14/2017
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

USB to Dual HDMI with no external power source!

By: sgto416 - 07/14/2017
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.

Awesome Dongle

By: NickD_CA19 - 07/22/2017
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.

Easy and small

By: djluislatino3 - 01/04/2018
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"

Works Exactly as Desired

By: pdx971 - 07/18/2018
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.
