QM55B

What the Samsung QM55B is built for

The Samsung QM55B is a 55-inch UHD 4K display from the QMB Series, designed for lobbies, corridors, reception areas and meeting rooms that run every day. Its 3,840 x 2,160 resolution carries four times the pixel count of Full HD, and the set is only 46.3 mm deep, so it sits neatly on a wall. The variant code LH55QMBEBGCXUE is the part number to quote alongside the QM55B model name.

Picture facts that matter on the wall

The VA panel offers a typical brightness of 500 nit and a 4,000:1 contrast ratio, with 178/178 degree viewing angles. Its non-glare surface, rated at 25% glass haze, keeps the image readable when daylight or ceiling lights fall across the screen. An 8 ms response time and a 92% DCI-P3 colour gamut keep motion and brand colours consistent. The Quantum Processor 4K lifts lower-resolution video towards UHD quality, so mixed-resolution playlists look more consistent on the screen.

Connectivity, software and meeting features

• Video inputs: three HDMI inputs (HDMI version 2), one DisplayPort 1.2 input and two USB ports.
• Control: RS232 in and out, IR input and an RJ45 network port for integration with room systems.
• Wireless: built-in WiFi and Bluetooth, plus SmartView+ screen sharing that the manufacturer lists for Windows, Android and iOS.
• Video calls: a built-in conference function works with a supported USB webcam, which is sold separately.
• Management: Custom Home locks room settings between meetings, and Tizen Zero Config supports remote app installation across several units.

Professional modes include Director Mode, which minimises post-processing, and DICOM Simulation Mode for medical teams. Auto Level keeps content upright when the panel is rotated to portrait. The set runs Tizen 6.5 with 16 GB of flash memory. Some features arrive through firmware updates, so confirm the feature list for the firmware version you will install.

Where the QM55B fits in Qatar

A hotel in West Bay could place one in the lobby for guest information, where the non-glare panel helps with bright daylight from entrance glass. A private school in Al Wakrah fitting out new corridors could run it as an always-on notice board, since the panel is rated for 24/7 operation. A government office in Msheireb with a bilingual team could use the HDMI input for laptop presentations and a USB webcam for calls with colleagues abroad.

What to plan before ordering

The QM55B weighs 18.1 kg and measures 1235.1 x 707.9 x 46.3 mm, so plan for two people during mounting and check that the wall or frame can take the load. It supports a 200 x 200 mm VESA pattern, and the manufacturer lists the WMN4070SG wall mount and STN-L4355G stand as options. Its operating range is 0 to 40 °C with 10 to 80% humidity, non-condensing. Qatar summer temperatures can pass 45 °C, so use it in air-conditioned indoor spaces and confirm the location with the SmartRooms Qatar team before installation. Power is rated at 100 to 240 V, 50/60 Hz, drawing 143 W in on mode and 0.5 W in sleep mode.

SmartRooms Qatar offers free site surveys, which are worth booking before wall-mounting a panel of this weight. Request a quote for the Samsung QM55B and we will confirm delivery to all eight municipalities of Qatar, professional installation and payment by bank transfer, cheque or purchase order.
