Overview
The Wall Mount Android Signage is the workhorse wall display of the range: an industrial IPS panel in a 40 mm mild-steel case with a glass fascia, hung in portrait or landscape. The 32 inch is Full HD at 400 nits; the 43 and 55 inch take a 4K open-cell panel at 500 nits and weigh 16.45 and 22.05 kg.
It runs the same open Android platform as the floor units, so a hotel can schedule a lobby welcome, an event board and a restaurant menu from one free cloud CMS, or play from USB where there is no network. Touch is optional, and the brochure lists PRO and ECO builds, with the PRO offered from 21.5 up to 65 inch.
