Accell Corporation
UltraAV® USB 2.0-HDMI Adapter

By Kevin Nakano

Accell USB 2.0 to HDMI AdapterAccell'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 UltraAV USB 2.0 to HDMI takes advantage of DisplayLink's flagship video processor known as the DL-195, which incorporates intelligent image processing algorithms. Coupled with the high
performance 128Mb DDR SDRAM memory interface and DisplayLink's DL2+ adaptive
compression scheme, video is virtually free of stutter and delay associated with many mid-level or lower-end video processors. On the back-end of the video electronics, HDMI signals are handled by a high performance Silicon Image SiI9022 HDMI® Transmitter. All of this works extremely well and provides a reliable extension of your video workspace, allowing you to easily extend your desktop. This is an especially important feature for those with laptops since video extension options are much more limited. Power consumption for the UltraAV USB 2.0 to HDMI adapter is low and the unit surprisingly does not even get warm when operating.

We tested the UltraAV USB 2.0 to HDMI on an HP d5000t desktop powered with a 2.5GHz Intel Core2 CPU (Q9300) processor with 3GB of memory, running Windows Vista (32-bit). The main display for this desktop is a 1080p monitor and we added a second 1080p monitor to test Accell's adapter. The system automatically recognized the device and configured the video for a second display once the adapter was plugged into the USB port. The adapter essentially extended the desktop to the right with the additional 1080p display. This really made for an effective area on the desktop.

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.

Extending your desktop has never been easier and with Accell's reasonably priced ($80 street) UltraAV USB 2.0 to HDMI Adapter you get full HD resolution and high performance video processing. Whether you need it for large spreadsheets, multi-tasking between documents, or just to expand your total useable screen area, this product makes it fast and easy. There is nothing more than the adapter in-line with the USB and HDMI cables, and there is no need for complicated installation procedures. Our configuration of two 1080p HD displays (1920x1080) worked flawlessly and once configured, the system always booted with both screens properly configured. If you are looking for a simple solution, Accell's new UltraAV USB 2.0 to HDMI Adapter has you covered.
