Just when MMT's 15.4-inch Monitor2Go was getting excited about its big USB display on campus title, Greenhouse Japan has strutted in and ruined the party with its 15.6-inch GH-USD16K USB secondary monitor. True, a resolution of 1366 x 768 won't give the screen bragging rights over Apple's 27-inch Cinema Display, but it should suffice for those on the move in desperate need of some quick dual-screen action. Especially since the accessory weighs less than 3 pounds, produces 18bit color depth and has a brightness of 220 nits while sipping just 5 watts of Serial Bus power. Speaking of dual-action, the monitor can also be set to clone or extend the connected computer's screen depending on user preference. Look for it to start shipping early next month to Japan for an estimated price of $214, glancing over its shoulder until an inevitable 15.8-inch newbie lopes onto the block.
