If you’re not fortunate enough to have a dual-monitor workstation, Iogear’s got something you should check out in the USB 2.0 External DVI Video Card. It’s what it sounds like, a USB device that adds a second video card and second monitor support to your PC via USB.
It’s very much like the VGA version launched last year, but with with DVI. No word on the exact specs, but we know it can support up to at least 1280×1024 at 24 bit color, is bus powered, and works with all KVMs.
