While the 2270L convinces with a 21.5" touch display, the 2470L inspires with a 23.8" and the 2770L with a 27" touch display. All three touchscreen monitors are equipped with energy-efficient TouchPro PCAP technology and edge-to-edge glass. The glass surface is clear or anti-reflective and scratch-resistant, as required. The blue light along with a flicker-free feature, two integrated speakers, and VGA, DP, and HDMI video ports provide a high level of viewing comfort. Plus, all monitors are Energy Star 8.0-certified and may be angled from 20° to 70°, thanks to their flexible stand. Fold the stand in for VESA mounting.
