Yes, this is an adorable small HDMI television with incredibly high resolution! We tried to get the smallest possible HDMI/VGA display with high-res, high-contrast visibility. The visible display measures only 7" (17.8cm) diagonal, and the TFT comes in an enclosure with HDMI, VGA and Composite inputs. The display is very easy to use - simply connect the included 12VDC adapter to the 2.1mm center-positive DC jack, then connect a digital video source to one of the ports. Voila, a television display! There's some little buttons on the front that let you enter a menu system for adjusting brightness, color and contrast. It auto-detects which input you have and switches to that one or you can 'select' from the menu which to display. It comes with a basic stand (shown) and there are four 'mounting thread' holes in the back in a 75mmx75mm square and you can use M4 screws to attach it to an enclosure. There's also a "Camera Mount" 1/4-20 hole in the bottom so you can attach it to a camera-ready mount.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any device with HDMI, VGA or NTSC/PAL output. It will not work with a device that only outputs DVI (without a DVI->HDMI converter) or SECAM.
For use with a Raspberry Pi we suggest editing config.txt as in the technical tab.
For use with a BeagleBone black, we found it works when plugged in, no configuration required. You may need a mouse/keyboard to keep the Bone display from going into 'sleep mode'
A 9V US-prong power adapter is included. The power supply may vary from the one shown in the photo, but it will definitely have a US 2-prong plug and will be a switching supply that can be used with 110-240VAC. We also powered it with 12V and it worked fine, and it might work at 5V.
