Samsung Outs 18.5in USB Powered Monitor

We've seen plenty of DisplayLink monitors in the last three years and in September we even got a taste of the first small USB powered displays, but now it seems we're ready for the next step...

Samsung has shown off a prototype 18.5in LEB backlit monitor at SID 2010 which can be powered by a single USB 2.0 cable. How? Power requirements were reduced to just 6.3W by "improving the transmittance of the panel and the luminance efficiency of the backlight," according to Johnny-on-the-spot Tech On!

As for the specs, the monitor has a respectable 1366 x 768 resolution, 1,000:1 contrast ratio and 250cd/m2 brightness. The downside at this stage is Samsung says the model has a lifetime of just 30,000 hours compared to 50,000 hours from a typical LED monitor.

When could we see them in production? "We are planning to start volume production of the LCD display for desktop PCs in 2011," a Samsung rep is quoted as saying.

With the greater larger power draw of USB 3.0 perhaps we could be seeing 22in and 24in USB powered monitors not too far down the road?

Is it possible to have your GPU power a USB or USB3.0 specifically for running the display?

If not, then where is this line of technology going? (A display that runs of the CPU is going to impair performance in everything other than simple applications)

@Dan - I am guessing that the intention is just to "power" the device and still utilise the graphics card to transmit the data. But could TR confirm whther that is the case. Will free up a plug socket at least...

Huh? USB2 can supply 500mA@5V and USB3 ups that to 900mA. That's a maximum of 2.5W and 4.5W so I guess maximum brightness is going to be limited to USB ports that provide more power then standard.

And what's with the lousy resolution? 19" displays are usually 1440x900.
