[quote]Monitors driven by USB alone are hardly new: heck, that’s the whole point behind those diminutive MIMO displays, which allow road warriors to expand their real estate by seven or ten inches by just popping one into their laptop’s spare USB port.
Historically, though, these monitors tend to be a bit too small to be useful. They’re really meant to hold an IM chat window or other similarly sized widgets, not do any real work on.
Not so the Green House, a giant USB monitor with a 15.6-inch display that only needs 5W of power to operate (to put that in perspective, the iPad needs a 10 watt USB port to even charge). The resolution of the display isn’t that bad, allowing you to at least watch 720p HD movies on it at 1366 x 769, and while the 400:1 contrast ratio and 220cd/m2 brightness rating aren’t going to beat out a monitor with a dedicated power cord, that’s still not shabby for a USB display only 140mm thick and weighing just 1.2 kilos.
The most impressive thing about the Green House, though, is that you can daisy chain up to six of them on one computer at a time. Try that with a regular monitor: you’d need an extremely expensive specialty card.
Unfortunately, the Green House currently isn’t available outside of Japan, but if you choose to import, you should be able to pick one up for about $215.[/quote]
TL;DR: 15 inch monitors powered by USB and can be daisy chained 6 times together.

Awesome. I'll have 6!
To be honest USB video cards have existed for some time, like: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16812225007[/url]
BUT a monitor receiving both power and signal from a single USB port is indeed revolutionary
yeah, and a 15'' monitor at that, too.
it's really impressive
the fuck is daisy-chained?
[QUOTE=.ediT;27524527]the fuck is daisy-chained?[/QUOTE]
It basically means multiple monitors.

Daisy Chaining is connecting a device to another device to another device until it reaches the main device.

look up "human centipede". It's a perfect example of a practical daisy-chain.

in other words, they're all chained together and then to the computer
to be entirely sure that .ediT understands the concept of daisy chaining

I just noticed this, and that better be a typo, because that is [b]thick[/b]
to put it in perspective 140mm is about 5.5 inches
I'm going to assume that they screwed up and added an extra zero
I don't see a practical use for this. If you are travelling having to carry around another monitor means a bulkier and heavier bag. It's also going to put more strain on your battery life. If you aren't travelling, you can get much, much better monitors for $200.

The point is that you can daisy-chain 6 of them together, trough a single USB port..

yeah, it's pretty easy to forget about terminating the one on the end.

And that is useful how? Assuming you can get each monitor for $215 that would be about $1300. $1300 for 6 crappy monitors. You could spend about that much (or less) and get enough monitors and graphics cards to have 6 monitors of much better quality.

The point being you dont need a expensive graphics card to support 6 monitors.
$215? Not worth it. Maybe if it was in the mid $100s.

Who said you needed an expensive graphics card to use 6 monitors? If you are just using the screens for productivity, cheap $30 cards will do the trick for auxiliary panels.
Paying that much money for such compromised screens doesn't make sense. Being able to "daisy-chain" them and support them solely through USB power is impractical for both stationary and mobile users.
720p video off of USB? It had better be USB 3.0. USB 2.0 has nowhere near the bandwidth to satisfy the immense bandwidth requirements of that much data moving around. Those USB video cards barely have enough bandwidth to display a 2D image, let alone do intensive BD video or 3D applications.

Um, what? I didn't know this was a 3D monitor.

It's a usb monitor. It's probably going to have a super slow refresh rate.
