Laptops rejoice! Sewell is spinning out a very inexpensive USB to DVI adapter to offer high quality video displays for those tiny notebooks displays. The process is simple. The external DVI video unit has a USB port which you connect to your laptop (or PC) and a DVI port you connect to you external monitor, turn everything on and you’re done.

The $120 price tag might seem a couple dollars high, but considering there is 128MB of flash memory used for buffering and processing the video signal you wont be disappointed. Sewell claims the USB to DVI adapter drove a 20 inch DVI screen with no visible differences what-so-ever.

The USB bandwidth is more than enough to transfer the necessary video data to the USB to DVI adapter, and the 128 megs of onboard RAM does the rest to bring you perfect performance every time.

With this unit you can turn any laptop into a three monitor system: 1) Laptop screen, 2) use DVI output of laptop 3) use Sewell DVI adapter for monitor #3.
