The USB32HDDVII USB 3.0 to HDMI® and DVI-I Dual Head Adapter turns an available USB 3.0 port into one DVI-I or VGA port (DVI to VGA adapter included) and one HDMI® output, with support for high-definition 1080p and 1920x1200 video and 5.1 surround sound audio (from HDMI® port only). Each display can simultaneously support the maximum resolution of 2048x1152 @ 60Hz.

The adapter delivers a convenient external video solution that makes it easy to add multi-monitor capability to a USB enabled desktop or laptop computer (optimal performance from USB 3.0, backward compatible with USB 2.0).

Leveraging the high-bandwidth (5 Gbps) SuperSpeed USB 3.0 interface, the USB video adapter functions as a convenient external graphics card that eliminates having to open the computer case for video card installation. The adapter delivers smooth, high definition content to multiple displays and can be used to mirror your primary desktop, showing the same image on each display, or to extend your desktop onto a second or third monitor to double or triple your workspace and increase your productivity.

The USB 3.0 HDMI® and DVI-I Adapter is backed by a 2-year warranty and includes free lifetime technical support.

Rated 5 out of 5 by from Great product & even better free customer support I have used the USB32HDDVII for about 9 months with no problems. Then, last week Windows did an update and this adapter no longer worked due to driver issues and conflicts. Curtis in support spent over 1.5 hours with me on the phone and helped resolve the issue, including resolving conflicts with software from other vendors. Curtis was obviously well trained, astute and friendly. Now that my computer is updated and conflicts resolved, the adapter works even better!!!

Rated 5 out of 5 by from Works great on my MacBook Pro! I bought this so that I could have two additional monitors with my MacBook Pro! It works great I'm running High Sierra 10.13.3. Initially I had difficulty getting the computer to recognize the other two monitors but after talking to their customer support it was a quick and easy fix. Works great makes my life so much easier!

Rated 5 out of 5 by from Excellent dual monitor support This is truly a plug and play device. We just attached it to the USB 3.0, attached our two monitors to the device and everything worked. Excellent! The device was also much smaller than I had envisioned, which is great as it takes minimal desk space.

Rated 5 out of 5 by from Enabled 3rd Monitor on M1 Mac Mini According to Apple, the newly released M1 Mac Mini can only support 2 monitors. I wanted a 3rd monitor for a flight simulator. This adapter allowed me to connect a 3rd monitor. Setting it up was tricky, but your online support person phoned me and walked me through the process.

Rated 5 out of 5 by from Works with Mac OS Sierra Although not officially compatible with Mac OS Sierra yet, they have a Sierra beta driver hiding in the zip file bundle that does work, and actually works better than the El Capitan driver. I had some bizarre video artifacts under El Capitan that have been resolved with the Sierra beta driver.
