This 15.6-inch TFT LCD screen from Green House may look like any other LCD monitor (except that maybe it’s a little smaller than we’re used to), but it has a magic trick: It runs on USB, which makes it one of the largest USB display’s we’ve seen.
With a distinctly average 400:1 contrast ratio and an acceptable 1366 × 768 pixel resolution, this monitor won’t out-perform any other screens you may have, but the gimmick is that it not only receives its image through a USB 2.0 port but is also powered by it. That’s right – there’s no external power-supply needed. The Green House monitor can run off just one USB port, which is more than can be said of the power-hungry iPad.
It’s not particularly cheap, though, at around $215 when it ships in Japan later this month. You could buy a decent 24-incher for less. On the other hand, you could use that 24-incher and this one together with just one port. Or, if you’re feeling a little ambitious, it’s possible to run up to six of these things simultaneously from one computer.
