Update: New Mac Drivers Released for Snow Leopard:Mac OSX driver download (note: Mac driver supports only Intel-based Macs). See the tech blog for a review of the original Mac driver which was tested in house here.
The USB to DVI supports up to six simultaneous displays when using six adapters, including widescreen displays, extending your desktop. See the article here.
Adding a quality DVI or VGA display through your USB port used to be science fiction. It is now science fact with the USB to DVI-I adapter. With onboard memory and video processor, it is an external video card you attach to your computer with a USB cable.
It used to be that you could add a display via a USB port, but the refresh rate and video quality was lacking. With this USB to DVI display adapter, complete with VGA adapter, you can add either a DVI or VGA display that behaves just like a monitor connected to a standard video card. It operates at a high resolution of 1600 x 1200.
The secret is video compression algorithm inside this little external video card. It carries the top-of-the-line DisplayLink chip that guarantees smooth performance on your secondary displays. Memory this large allows the adapter to perform like a standard video card. The USB pipeline (maxing out at around 480 mbps) is more than enough bandwidth to provide top-notch video connectivity.
As excited as we were for the release of this model, we tested it right when they came in. Using two simultaneously, the unit performed with flying colors.
We tested it on an unimpressive Dell Latitude D520 Centrino Duo with 512 RAM and it easily handled five USB to DVI adapters driving 19- to 21-inch flat screens (including widescreens). We also used the auxiliary display port on the laptop's docking station for a total of six simultaneous beautful displays, including the laptop's built-in display.
