QM50B

What the QM50B is and what it does well

The Samsung QM50B is a 50-inch UHD signage display from the QMB Quantum Processor 4K range, built for organisations that need a screen to run content for many hours every day. Its 3,840 x 2,160 VA panel is rated at 500 nit typical brightness and a 4,000:1 contrast ratio, and the datasheet specifies 24/7 operation support. The 178/178 degree viewing angles keep text readable for people standing to the side of a corridor or lobby.

Picture processing, colour and screen behaviour

The Quantum Processor 4K upscales lower-resolution video towards UHD quality, which helps when a site mixes older HD footage with new 4K artwork. The panel covers 92% of the DCI-P3 colour space, and an 8 ms response time keeps moving content clean. A non-glare panel with a 28% glass haze rating reduces reflections from windows and overhead lighting, which matters near glazed entrances.

Ports, control and wireless sharing

The rear panel offers three HDMI inputs (HDMI version 2), one DisplayPort 1.2 input, two USB ports, an RJ45 network port, RS232 serial input and output, and an IR input. A stereo mini jack provides audio output, but the unit has no audio input. WiFi and Bluetooth are built in, and the Tizen 6.5 operating system runs on 16 GB of flash memory.

• SmartView+ wireless screen sharing from Windows, with mobile support delivered through a firmware update
• Custom Home lets admins lock selected room settings so they cannot change between meetings
• Tizen Zero Config lets IT register new apps and install them remotely across sites

For video calls, the built-in conferencing function works with a USB webcam that you buy separately. The datasheet lists nine supported Logitech models, including the C920, C922 and C930e. The source notes this capability arrives through a firmware update, so confirm the current firmware status in your quotation before relying on it.

Size, mounting and environment planning

The set measures 1121.4 x 643.9 x 46.3 mm and weighs 13.4 kg, with a packed weight of 17.6 kg, so two people should handle the unit. It mounts on a 200 x 200 mm VESA pattern, and the bezels measure 9.2 mm on the sides and top and 11.2 mm on the bottom. SmartRooms Qatar offers free site surveys, which we recommend before wall-mounting a panel in a new Lusail or Msheireb fit-out, so wall strength, cable routes and mounting height are checked first.

The rated operating range is 0 to 40°C at 10 to 80% humidity, non-condensing. Qatar summers exceed 45°C, so the unit should sit in an air-conditioned space, away from direct sun and open loading entrances. Power input is AC 100 to 240 V at 50/60 Hz, and the datasheet gives a draw of 171 W on and 0.5 W in sleep mode. The optional wall mount WMN4070SG and stand STN-L4355G are listed for this model.

Where it fits in Qatar

• A private school in Al Wakrah placing it in a corridor to show timetables and student work
• A clinic in Msheireb using it in a waiting area for patient information and queue updates
• A hotel lobby in West Bay showing event listings and wayfinding
• A bank branch in Al Sadd displaying service messages beside the customer waiting area

For a school ordering several units, SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and delivers to all eight municipalities of Qatar.
