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.
Also: 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.

Works with virtual Windows PCs, too

Pros: I'm using this to get around a limitation of VMware Fusion: lack of support for multiple monitors in Windows. I plugged it into my MacBook Pro, installed the *Windows* drivers in the virtual machine, et voilà. Instant second monitor.
Cons: The mouse gets squirrelly because it doesn't know what the @#$% is going on, but forcing Fusion to draw the mouse pointer in software pretty much fixes that.
Other: I wasn't sure it would work, but I was cautiously optimistic about the DisplayLink technology. Turned out to be a good bet.
Plug and Play Perfection

Pros: I looked high and low for an easy and affordable way to add multiple monitors to my MacBookPro. I finally stumbled across a forum post about the Sewell USB to DVI external video card which had just released Mac beta drivers. I took a chance and tried it.. it was exactly what I was looking for. I plugged it in, turned on my MBP and it worked instantly. I liked it so much I bought another one to use at work.
YES - Windows 7 Driver

Pros: This is a great product. It is so nice to work on dual monitors. Upgraded to Windows 7 Beta and lost the driver a few months ago. Thanks for getting the driver update out ahead of Windows 7 release. Very much appreciated!!

This product works perfectly. The resolution of 1600x1200 is exactly what I use for my other monitors, so this was a perfect option for me. The taskbar options are very easy to use.

Does the job and runs great both on VGI and DVI for OS X 10.6 on MacBook Pro 2010
I have a laptop and two additional monitors. Do I need two USB to DVI addaptors or will one control the laptop, plus the two external monitors?
Typically your laptop will have an integrated monitor ouput for one external screen, then one USB to DVI would drive the second external monitor. If you need a third external montior (or if you don't have a video out from the laptop) then you would want two USB to DVI adapters.

Does this product support 1680x1050, and will it support all resolutions (including that one) when the Mac driver is released?
Yes, it will support 1680x1050 resolution, also when the Mac driver is released.

my new HP touchsmart runs on a windows 64bit system. do you have drivers in the works for this or is there a divice the I can buy that will give me video out from a usb port? Please Please help me.
Unfortunately, Windows 64-bit drivers are not available at this time. The chipset manufacturer is working on them, but they are not yet available. We do not have any USB video adapters like this that do support Windows 64. UPDATE: now with Vista and Windows 7 64-bit support! (Does NOT support XP 64-bit)
