Rated 1 out of 5★ by toptensearches monitors not stable Ordered 2 these USB monitors, and used them in tandem with 2 other standard VGA flat screens to have a 4 display systems in total.The USB monitors flickered and blacked on and off with any Type of modern use, including loading applications and searching the web.Even typing in and loading a search on Walmart.com resulted in the USB monitors flickering out black, while my other 2 standard VGA monitors remained stable and not affected.testing included using the USB monitors by themself as stand alone ( only one USB monitor connected at a time with no other monitor type connected) but had the same results.The selling point of these monitors suggest that they are stable and powered thrugh USB ports only, The operation manual gives instructions on useing two USB ports to provide Optima power for stability, and this was done in all the above scenarios, and the the desktop internal 750watt power supply being used was more than sufficient to carry load of USB demand.It should also be noted while there is a power socket on the back of the USB monitors there was no power cord adapter included.Although the concept of using only USB ports to connect and power a monitor is a phenomenal idea, the technology present in these monitors do not provide for stable uses at this time.Also, the USB monitors do not have a power on off button or any type of visual display brightness or color adjustments whatsoever, and there is no way to reduce the resolution.The only way to power off the USB moniors is either set the screensaver sleep mode on your system or to physically unplug the USB cable itself.The USB monitors were return to a local Walmart store for a full refund, after 7 days a vigorous testing failed to stabilize the monitors. 01/20/2013
Rated 2 out of 5★ by SteveTheWebGuy Limited Compatibility I needed a mobile monitor for work and demos. I considered this piece simply because of fewer cords to attach and less items to store in my demo 'kit'..but my Toshiba Satellite video drivers and USB power were not sufficent with this item and I ended up buying a smaller traditional LCD also from AOC (after returning this to my local Wally spending less bucks!). This 22 worked wonderfully on the main production computer with no issues - brightness was terrific and integration to 3 monitors was a breeze. While this should work in most situations, be aware not all can be assured...Wally's price is the best in the market..try it and see...if not, take it back to your store and buy an AOC 19 (store stock most likely) with reg RGB cable connections (included)...Had several rounds with AOC tech support (via email and chat- in china!) and their engineer is looking into the issue...but as I said...no one item can fully support everything from everyone...If you're running XPsp2 or Pro, 7sp2 or 8, you should be good to go...Vista and other intermediate os's, maybe not so much...hope this helps! Cool piece, wish I could'a kept it! 01/31/2013
