Product Review (February 2012)
By Kevin Nakano
Accell's new UltraAV USB 2.0 to HDMI video and audio adapter makes it easier than ever to add an additional HDMI monitor to your laptop or desktop by simply plugging in a USB 2.0 cable. No longer is it necessary to open up your desktop and install a video card to get this capability. The unit can stream 1080p HD video and audio from a computer's USB port to a standard HDTV. In addition, computer monitor resolutions up to 1920x1200 or 2048x1152 (widescreen) are supported. Users can mirror, extend or rotate the computer's desktop on a second monitor. The UltraAV USB 2.0 to HDMI is compatible with Windows and Macintosh and can support up to 6 displays (one adapter per display). Since we only received a single test unit, we could not verify the performance of more than one UltraAV USB 2.0 to HDMI connected to our computer. The UltraAV USB 2.0 to HDMI also includes a (1.8-foot) USB 2.0 A to Mini B cable, driver CD, and a Quick start guide (no external power adapter required). However, there is no HDMI A-A cable included, so you will have to get your own.
The video looked great and we were able to move items around without any performance issues. There was no noticeable lag or break-up of the video and the mouse cursor was very responsive. As a stress test, we launched Cyberlink's PowerDVD 12 to see the video performance with HD content. Due to the high bandwidth requirements, we could see some minor motion artifacts (in the form of stutter) in the video when compared to our main display, but they were rather minimal and you had to look for them. The content was completely watchable, so it was not an issue for us. Personally, I was surprised that it looked as good as it did based on some similar products on the market from a year ago.
Our second test system was an HP dv7 laptop with a 2.0GHz AMD Phenom II P860 triple-core processor with 6GB of memory, running Windows 7 (64-bit). We used the same 1080p monitor for this test and ran similar content for an apples-to-apples comparison. We saw similar performance, but due to the slower processor in this laptop, the high speed video had a more noticeable stutter that what we saw on the desktop. Still quite good and watchable, but certainly a small difference in performance from the faster machine.
