EP5542

A tall 4K portrait screen for public information

The ViewSonic EP5542 is a freestanding 55-inch digital ePoster kiosk with a 4K UHD panel (2160 x 3840) set in portrait orientation. Its 9:16 format gives a display area of 1209.6 mm by 680.4 mm, a shape that suits entrances, corridors and reception areas where visitors walk past a tall, narrow screen. It is built for messages, directories, wayfinding maps, schedules and promotional loops that visitors need to read while passing by.

Panel brightness, glare and viewing angles

The VA panel is specified at 450 nits typical brightness and a 1,300:1 typical contrast ratio, with 178-degree horizontal and vertical viewing angles, so people approaching from either side see the same content. The anti-glare surface, rated at 7H pencil hardness with 2% haze, reduces reflections from ceiling lights and glazing. The backlight is rated at 30,000 hours typical life, and the response time is 9 ms typical grey to grey.

Playback, remote control and connections

An embedded quad-core media player with 16GB of internal memory handles playback without a separate PC. It reads JPG, BMP and PNG images, common video files including MP4, MOV, MKV, MPG, AVI and WMV, and MP3, WAV and AAC audio. The inputs include three HDMI 2.0 ports, one DisplayPort 1.2 port, one RGB/VGA port and a 3.5 mm PC audio input. Control is available through RS232 or a LAN (RJ45) connection, and the vController app manages settings across multiple units on the same network. Three USB 2.0 Type A ports and an S/PDIF output add flexibility.

Where it fits in Qatar

• Government and corporate reception: a ministry or authority in Msheireb or Doha's business district can use it for visitor directions and service information in an air-conditioned lobby.
• Campus and school entrances: a university building in Education City or a private school in Al Wakrah can show timetables, events and campus maps, with the stereo speakers available for short audio clips.
• Hotels and malls: a serviced apartment building in Lusail or a retail centre in West Bay can display promotions and floor directories near the lift lobby.

What to plan before installation

The unit weighs 62.7 kg net and stands 1870 mm tall, with a physical footprint of 768.5 mm wide and 450 mm deep. Plan the route from the delivery door to the final position, checking the 2034 mm packaging height against lifts and corridors. The power input range is 100-240 VAC, which covers Qatar's 240 V, 50 Hz supply; typical draw is 126 W and maximum draw 149 W. The operating range is 0°C to 40°C at 20% to 80% non-condensing humidity, so the kiosk should stay indoors in an air-conditioned space, away from direct sunlight. SmartRooms Qatar provides a free site survey, the simplest way to confirm placement, cabling and sightlines before you order.
