HP LD4720tm

The HP LD4720tm (individual unit pricing not available) is a 47-inch digital signage sporting a 1,920 by 1,080 resolution, a multi-touch LCD and USB device playback support among other features. Packing a programmable anti-glare and anti-static screen, the display comes with multiple display inputs, the ability to daisy chain up to 25 devices through VGA and more.

Design and Features
Visibly designed with minimalism in mind, the LD4720tm touts a thin, black plastic bezel with a frame that measures 5.2 inches thick. In addition to two speakers embedded within the screen, it also packs an audio output jack. Designed and tested to run in 24/7 conditions, this display comes with both a DisplayPort input and output, one HDMI input, both a VGA input and output, a USB 2.0 port, an RJ-45 Ethernet port and more.

Popping open the LD4720tm would reveal hardware that powers both 1,200 to 1 static and 3,000 to 1 dynamic contrast ratios. A 9 millisecond response time is also tucked into the display, and users can control the digital signage through either a serial connection or Ethernet.

Users can automate media playback through HP's embedded Media Sign Player technology and a connected USB drive. Thanks to integrated scaler technology, up to 25 units can be daisy chained via either VGA or DisplayPort to create a larger matrix image. HP also made it so the LD4720tm is fully Windows human interface device (HID) compliant.
