A secondary display powering off a USB port is nothing new. A 15.6-inch LCD monitor doing the same, however, is downright unheard of. Until now with the Green House GH-USD16K TFT LCD.
Granted, it's far from the best desktop screen money can buy. With a 400:1 contrast ratio and a maximum 1,366 x 768 pixel resolution, it's decidedly average for modern displays. That means you won't be stunning any friends with its picture quality anytime soon.
The Green House GH-USD16K, however, does something else downright impressive: it only uses a single cable connection, tethered to one USB port on your computer. Not only does it receive its image through that connection, that's where it draws power, too -- no external power supply necessary. Really. And it only requires USB 2.0.
Monitor dimensions are 377.7 × 141.8 × 287.8 mm, with a weight of 1.2 kg. We're not sure how big your desk is, but imagine plugging several of these on a single computer -- multiple screens galore.
The rub is that Green House will be selling the GH-USD16K in Japan only (at least for the first shipments at the end of the month). Plus, at a time when LCD monitors are dirt-cheap, it's going for a rather expensive price (around $215).
