WM85B

An 85-inch Flip Pro display for rooms that share one screen

The Samsung WM85B belongs to the Flip Pro range of interactive displays. Its 85-inch panel uses a 4K VA layer at 3,840 x 2,160 pixels with an infrared touch surface, so a presenter can write, draw and annotate directly on the glass while the content stays clear for the whole room. It runs the Tizen 6.5 operating system from 32GB of flash storage, so it works as a complete display for a classroom, meeting room or lecture hall.

Touch, pen input and picture performance

The key figures for a buyer are these:

• Latency: 26 ms, with prediction logic that keeps pen strokes smooth
• Pen pressure: 2,048 pressure levels built into the display
• Multi-touch: quoted for up to 20 people, a figure the manufacturer qualifies with a note on single-touch use
• Picture: typical brightness of 350 without glass and 220 with glass, 4000:1 contrast without glass, 178/178 viewing angles, 8 ms response time and 72% colour gamut
• Surface: 2% glass haze without glass, a shatterproof film and an antimicrobial coating on the screen surface

An ambient light sensor adjusts brightness to the room lighting. The antimicrobial coating covers the screen surface only and does not protect users against bacteria or viruses, so treat it as a surface feature rather than a health measure.

Ports, wireless sharing and network connection

The input panel gives a presenter several ways to connect:

• Two HDMI 2.0 inputs with HDCP 2.2, and one DisplayPort 1.2 input
• Four USB ports: two front and one rear Type-A, plus one front USB-C
• Front USB-C with screen mirroring, touch control and external charging up to 65W
• RJ45 LAN, RS232 control, Wi-Fi, Bluetooth and a stereo mini-jack audio output
• An OPS slot for third-party school information systems and learning applications
• AirPlay 2 and SmartView+, which supports up to 50 wireless devices and multi-view across four screens

Wireless sharing helps in rooms where students or visitors bring their own devices. The manufacturer also lists video call apps that run on the WebRTC API, with a webcam sold separately from nine supported models.

Where the WM85B fits in Qatar

• A private school in Al Wakrah fitting out large classrooms, with the OPS slot running its school information system on the screen.
• A university lecture hall in Education City, where students at the back can read tables and diagrams while the lecturer annotates in pen mode.
• A boardroom in West Bay holding video meetings with teams abroad during the Sunday to Thursday working week.

Planning the installation, power and environment

Plan for the weight and room conditions before ordering. The set weighs 75.2 kg, the package 91.6 kg, and the set measures 1945.8 x 1151.1 x 89 mm with a 20.4 mm bezel on the sides and top and 44.7 mm at the bottom. The VESA pattern is 600 x 400 mm. The manufacturer lists an optional mount under model WMN8200SF, and moving the panel between rooms needs a separate standing mount.

• Operating range: 0 to 40 degrees Celsius at 10 to 80% humidity, non-condensing, so use an air-conditioned indoor room away from direct sun and glazing
• Power: AC 100 to 240V at 50/60 Hz, 528W on-mode consumption at 100 to 240V, 0.5W in sleep mode
• Energy class: A+
