1. Review Date: 2009-10-13

   Bought this item for a very specific purpose: rapid prototyping for touch-screen interfaces. I wasn't concerned with the terrible 6 o clock viewing angle or the 262k colors. It just had to work as a touch screen. Which it barely does.
   Contrary to the funny translations from the manual, I was able to display full motion video onto this screen without any problems. Yes, the video files I was testing weren't great but then again neither is the native resolution of the display. The display brightness isn't very good. For indoor use and dark computer labs, it's ok. Would not recommend puting it in any kind of direct illumination.
   Construction and assembly seem decent but nothing to write home about. The display has 3 buttons concealed on the left edge under its little blue power LED. I'm glad to report the LED is not of the light-house kind and won't need to be masked off. The buttons control power (or stand by) and brightness. You really won't be using the brightness controls though, unless you're prototyping a bed-side clock. The entire screen is powered via a Y cable USB connection (mini USB at the display end).
   The software is...beyond words. The manual does a good job of pointing you in the right direction, even with instructions of the type "The calibrated Touch Screen coordinates may vary upon the lapse of usage time." Unfortunately, the drivers are a mess. The display part of the drivers seems ok. I successfully installed the display on a Shuttle PC and a laptop (M2400). The touchscreen on the other hand, installed properly only on the Shuttle. On the laptop it refused to properly scale the calibration screen to the available display area, such that only 1 of the 4 points was actually visible. This rendered the ENTIRE touch screen completely useless. After re-installing the drivers from the CD...twice, I went online and downloaded the same drivers directly from the website. Once again, the display driver worked correctly but the touch screen driver kept on failing to initialize properly even though I rebooted. I chose to ignore the failure and attempted to calibrate once again. It worked! The app properly scaled the calibration display to the screen and I was able to calibrate and use the touch interface. I'm sure I'll keep getting that failure every time I connect the display though.
   There isn't much else to be said. At $200, this is at best an alpha candidate for a product. These days you can have a full 19 inch display for less or a very nice photo frame with way more brains than a simple display. So the question you need to ask yourself before taking out your credit card is "How much do you NEED the USB interface?" Mine's already packed and ready to return.
