DisplayLink makes video chips that let you connect an LCD to your PC via USB, which is highly convenient for adding a second display. Even more convenient? Going wireless. Iogear introduced its Wireless USB-to-VGA Video Card that uses DisplayLink's technology to output a video signal via WUSB to multiple monitors, TVs, and projectors at up to 1,680x1,050 resolution and 16.7 million colors. Iogear expects the WUSB external graphics adapter to become commercially available in mid-2008 from monitor, PC, and peripheral manufacturers.
