Lilliput 619AT | 7 Inch LED HDMI Touch Screen Monitor

I wanted a USB powered device to drive a small Intel PC that occasionally requires a traditional monitor. There were a few requirements that made the Lilliput appear to be the better alternative even though it requires its own 12V power source. They were:1. Needed to run at a relatively high resolution, preferably high definition.2. Needed to support a touchscreen interface.3. Needed to draw power solely from USB or portable batteries.4. Needed to be portable as a hand held display.5. Needed to work as a primary monitor recognized during system boot.The Lilliput 619AT supports all of the above successfully overall. The device itself is a little bulkier than I would prefer, making it not entirely practical as a handheld display but adequate. The pack in cable is also a little on the bulky side, but it does not prevent the device from being used as intended. If being used with a Windows 8.1 computer, it is recognized out of the box as a touchscreen device but the calibration is very far off. This was corrected by installing the eGalax software included on a small CD in the packaging. The display is crisp, and the end user should to be sure to calibrate it accurately (with a stylus if possible). It supports portrait and landscape mode, but the setting needs to be adjusted through the operating system.For the system I have configured, there is about a half-second delay between a finger press and the pointer moving to the selected spot when running in high definition mode. Using the stylus seems to get a slightly better response, and is necessary if making fine grained selections on the screen. The touchscreen is still useful and usable without the stylus, though, and the device outperforms similar-sized touchscreen displays on features and execution. The Lilliput 619AT works as advertised, and the negatives are minor.

The first one I received had a large number of dead pixels and was immediately sent back for a replacement. The second one appeared to be in perfect working order. I originally purchased this to pair with a Raspberry Pi and XBMC as potentially and in-car media solution. It took me a good few days to get the touch screen configured but it seemed to run well. After about 2 weeks of playing around with it, multiple pixels in the middle of the screen got stuck bright green. I tried a couple of the pixel fixers and decided to just send it back for a refund. I imagine it could have been quite useful had the screen been better quality.

It does exactly what it says it does. It's great for video or small signage, but don't expect to be able to use it as a Windows desktop very well since the resolution isn't high enough. For what it's designed to do, it works perfectly.

Nice monitor! Doesn't have a power source will need to buy a external battery or keep it plugged up to the a/c adapter. We used it as a display monitor for our high-pod camera
