Typically, when you think of a USB-powered monitor it is something small, say 7 inches or so. Samsung, however, has developed a new USB-powered monitor that measures in at 18.5 inches which makes it more than enough to use with your desktop. Samsung has apparently improved the transmittance of the panel and the luminance efficiency of the backlight to allow for the larger size. Power consumption for the monitor is a measly 6.3 watts and uses a USB 2.0 cable that has a forked end to supply the power. The only drawback of the edge-lit backlight technology powering this LCD is in the lifespan which is down to 30,000 hours. A typical LCD monitor has a lifespan of 50,000 hours so the USB-powered one should last about half as long. Look forward to seeing this and possibly others hit store shelves sometime next year.
