AOC Revealing 22-inch HD USB-Based Monitor at CES
AOC is launching a 22-inch USB-based monitor next month. In the meantime, consumers can get an early glance next week at CES 2012.
Earlier this week AOC introduced a 22-inch monitor (e2251Fwu) that draws its power and signal through a USB port. This $199 plug-and-play panel is scheduled to be shown next week during CES 2012, but won't see an actual retail release until February 2012.
According to the specs, the 22-inch AOC USB Monitor will support a 1920 x 1080 resolution @ 60 Hz, and will be compatible with Windows XP / Vista / Windows 7 & Apple MAC OSX Tiger / Leopard and Lion -- Linux support is also available through many of the standard distributions. The display will also be HDCP compatible and have an ultra-slim form factor, measuring just 10.6-mm thin.
As for other specs, the display will feature a brightness of 250cd, a 20,000,000:1 Dynamic Contrast Ratio, a 5ms response time, and LED-based backlighting that allows it to consume 50-percent less energy than many CCFL backlit monitors. A removable stand even allows it to "instantly transform into a digital photo frame or presentation display."
"Every AOC monitor is manufactured to meet the most stringent green standards," the company said. "Along with being mercury free, the packaging for the eco-friendly 22-inch USB Monitor is made from recycled materials. In addition, AOC’s industry-leading LED display technology allows for a powerful and crystal clear display while minimizing power consumption."
Those heading to CES 2012 next week can check out the new 22-inch USB-based monitor at the Bellagio, Monet 3 Ballroom. The company didn't state an actual release date for the monitor in its announcement, so stay tuned for more info.

Less power.Less power cords.
What next? Wireless monitor that draw power from the air
doesn't seem too hard to do. Look at the power usage of a 10 inch tablet, it is generally at around 1.5-2 watts for the entire unit.
if you get rid of everything except the display driver and LCD screen and you will get even lower power usage numbers
at 2.5 watts, a USB port can easily drive a 22 inch LCD if it uses similar technology to what you find in tablet screens
I don't understand. How can the USB deliver enough bandwidth for a 1080p video signal? I'm guessing it needs to be compressed.

1920x1080x24x60/(8*1024^2) = 355.957MB/s is the required bandwidth for a 1080p signal @ 60Hz
USB 3.0 affords ~596MB/s, so it should work.
I'm more impressed by the fact that it can be powered by entirely by USB.
1080p... yet another TV screen for use with a PC. :-(
I use 1200 lines for years and wish I had even more when editing in Photoshop or Premiere.

that is if they are doing raw video. Hopefully they are not doing the whole codec crap where a compressed signal is sent to the monitor and it decodes it (causing up to 3 seconds of delay between something happening and it showing up on the screen)
USB 3 should allow for more power if it is using it, but USB 2 and the standard 500ma is enough. keep in mind that a 10 inch tablet screen may have a brightness of close to 400cd and pull about 1 watt, or a little over a watt, the 22 inch USB display is basically at nearly half the brightness and a little over twice the size.
Just to correct that it is more than twice the size. Shouldn't you be looking at the area instead of diagonal length?

Very good point, after all a 12megapixel image is "Only" double the size of a 3megapixel image.
I know I never seen a 2.5(4.5 if usb 3.0 in ull bandwidth mode) watt computer screen.
I would guess it is based on something from DisplayLink, as it would be backwards compatible with usb 2.0 that way.

The screen area is 4 times bigger though.
But what is rendering this video? The cpu?
I can't see it being anything other than CPU considering it's using USB. This would means it would be relatively useless for anything for than casual email and web browsing tasks which is likely to be the target market for a monitor in this price range.

Please explain to me how a 12 mega pixels is twice as large is 3 mega pixels. It may be twice as large in both width and height (assuming both images are the same shape) but it is still four times the size of the 3 mega pixel image. The width and height of an 8x8 square are each twice the size of the width and height of a 4x4 square but an 8x8 square still has four times more area (aka size) than the 4x4 has.

web browsing and email from a 22 inch 200 dollar screen? I think you've misplaced your words, there. Anyway, it's not going to take mounds of processing power to render the images.
22" is hardly large and $200 is a low budget for a monitor. Our company writes software for the film and TV industry, we do a lot of design and processing and use 24" monitors minimum with 27 and 30" more common these cost anything from $600 to more than $1200, hardly the $200 range. They are driven by higher end NVidia and ATI cards which render much of the content using technologies like CUDA. To successfully edit HD video for example, graphics card acceleration makes a huge difference a software only version would crawl - just try using the standard unaccelerated generic Windows 7 drivers and you'll see what I mean! I therefore stick to my statement that I suspect they will be used for more simple tasks.

That's why they create 16:10 IPS monitors with 1920x1200 for your intense pp sessions and 27" and 30" if you need more resolution. This monitor is more for the average user, less cords equals win!
This will make troubleshooting easier for those customers out there who have a hard time matching up the BLUE cable to the BLUE port.
The video rendering is all through the CPU then what if there were dual USB monitors? What's the monitor management suite that will allow me to extend, or mirror my displays? Basic Win 7 desktop properties? Ew.
A nice advantage though for the "green" conscious persons.
I couldn't agree more, at the proposed price point, it clearly isn't meant for people who demand more than an average user. Editing word docs, drawing up spreadsheets in fact pretty much all standard office tasks will be easily catered for by the CPU bound graphics power, assuming of course they don't include some for of rudimentary acceleration within the monitor itself.
I'm not sure about how it would work for multiple displays but I suspect a driver will be released that allows Windows to see the monitor properly and thus allow all the usual desktop properties to function as normal.
DisplayLink USB graphics technology is a unique approach to USB graphics, allowing smooth video playback and providing a low latency connection that feels very much like a traditional monitor while providing the "plug and display" simplicity of USB. DisplayLink USB graphics technology allows for high resolution, full 32-bit color graphics, at resolutions up to 2560x1152 (depending on chip used). Here's how it works:
1. DisplayLink software is installed on the PC and uses resources available in the CPU and GPU to process the graphical information from your USB connected display.
2. Updates to the screen are automatically detected and compressed using the DisplayLink compression technology (DL2+ or DL3). This adaptive compression technology automatically balances the compression methods based on the content, available CPU power, and USB bandwidth, providing the best possible USB graphics experience at any given moment.
3. Compressed data packets are sent over the standard USB 2.0 cable as quickly as possible to maintain a very interactive user experience.
4. A high speed DisplayLink chip embedded in the monitor, docking station, projector or adapter decodes the compressed data back into video or graphics data.
--------------------------
So.. It uses a driver, the CPU&GPU and an embedded DisplayLink chip on the display. And looking at the link provided below, there's already ALOT of displays that has this technology, and its designed for USB 2.0.
I'm very interested in those small factor, 4~7" display units.. coupled with those ultra small PC units.
