Certified by the USB-IF, this unit enables any machine with a spare USB port to stream video to a TV or projector with resolutions as high as 720p. So long as your USB dongle is plugged into your machine and the VGA adapter is connected to a display, you’ll be good to go within a 30-foot radius. According to IOGEAR, the product is only compatible with Windows XP 32-bit or Vista 32- / 64-bit, but those with no qualms about that can grab one next month for $229.95
