We also found favor with its media playback capabilities. The Smart Display with Android 4.0 supports most major media formats, including .mp3, .mkv, .ogg and .wav audio, .mp4 and .avi video and VP8 streaming. To test video playback, we launched the media player from within Android's Gallery app to play 720p .avi and .mp4 videos from a USB stick. Both played smoothly and with loud and clear audio. We also tested the unit's ability to work out of the box with a variety of Bluetooth and USB keyboards and mice; all worked flawlessly.
The Smart Display's rear panel is home to a VESA-mounted kickstand, which can be swapped for an optional ViewSonic wall mount or other third-party option. A small plastic cover hides the DC power and RJ-45 connectors, a MicroSD slot and its micro HDMI input port. Of its three USB 2.0 ports, two are Type-A connectors and one is micro. ViewSonic says it will include a cable for this as well as for the micro HDMI port; none came with the test unit. There's also a Kensington security slot and 3.5mm headphone jack.
We wouldn't recommend the VSD220 as a productivity workstation; the dual-core OMAP 4 processor in the VSD220 seemed underpowered, and the touch screen was sometimes unresponsive and had trouble keeping up with fast finger-swipes. But for its intended purpose as an internet-ready all-in-one PC for purpose-built applications, digital signage and information kiosks, we recommend the VSD220 Smart Display; it fits the bill nicely.
