HD video via a USB port
Gefen has released a new USB to DVI graphics adapter offering a convenient way to connect additional high definition, digital video displays to most windows-based PC computers.
The tiny unit allows a plug and play connection of a DVI or VGA display to the USB 2.0 port. This means you can add digital video displays or projectors to your laptop or personal computer for simultaneous video delivery without using a DVI port.
Testing has shown that up to six USB to DVI adapters can be connected to one PC at a time with reliable delivery of video to all six displays.
