IO Data is looking to broaden your viewing horizon with their USB to RGB dongle. Ideal for laptops without video or D-Sub output this “could” help improve your viewing experience by replacing the laptop screen with a bigger monitor. Then again, if you are missing video out, you’re probably missing USB too.
Before you consider building a panel of monitors from your laptop be sure to check your video card capabilities as most laptops can’t support more then original screen plus one monitor anyway. Another option is trying a new USB monitor which does the video processing for you.
