QM55C

What the Samsung QM55C is designed to do

The Samsung QM55C is a 55-inch 4K UHD display from the Crystal UHD Signage QMC series, made for indoor digital signage, wayfinding, menu boards and information walls. Its 3,840 x 2,160 VA panel shows sharp detail at close viewing distance, and the 0.315 mm pixel pitch keeps text crisp on a reception desk or along a corridor. The display runs Tizen 7.0 and includes 16GB of flash memory.

Slim depth, even bezels and centred mounting

At 28.5 mm deep, the set is thin enough for narrow corridors and lift lobbies where bulky screens block movement. The 11.5 mm bezel is the same width on all four sides, so a screen rotated to portrait looks balanced rather than top-heavy. The VESA holes sit at the centre of the back with a 200 x 200 mm pattern, which spreads the weight evenly and reduces unintended tilting when the panel is turned to portrait. A Slim Fit Wall Mount is sold separately, and the WMN-B50SC mount and STN-L4355C stand are listed as optional accessories.

Picture performance and the specifications that matter

• Brightness: 500 nit typical, with a non-glossy frame and a non-glare panel.
• Contrast: 4,000:1 contrast ratio with the Mega dynamic contrast setting listed in the data.
• Colour and viewing: 72% NTSC colour gamut, 178/178 horizontal and vertical viewing angles, 8 ms response time.
• Upscaling: Quantum Processor Lite 4K raises lower-resolution video to UHD.
• Operation: 24/7 operation support.

Brightness and contrast matter most in lobbies with daylight from tall windows, because glare and washed-out content are the usual complaints with signage that is viewed from a distance.

Connectivity and control

The QM55C provides three HDMI inputs (HDMI version 2) with HDCP 2.2 support, one DisplayPort 1.2 input, two USB ports, an IR input, RS232 input and output for control systems, and an RJ45 network port. It also includes Wi-Fi and Bluetooth. Audio input is not provided, but a stereo mini jack output is available. SmartView+ enables wireless screen sharing in meetings, and Samsung VXT CMS, sold separately, handles remote content and device management.

Where it fits in Qatar

• A corporate reception in West Bay or Lusail showing visitor information, brand content and directions to floors.
• A private school in Al Wakrah fitting out corridors and common areas with timetables and announcements, where several units are ordered on one LPO.
• A clinic or hospital outpatient area in Doha using the display for queue information and wayfinding, with the environment checked before fixing.

Planning the installation

The set weighs 15.7 kg and measures 1237.9 x 708.8 x 28.5 mm, so plan the wall fixing and the people needed to lift it. The operating range is 0 to 40 C with 10 to 80% humidity, non-condensing. Summer temperatures in Qatar often exceed 45 C, so the panel should sit indoors in an air-conditioned space, away from direct sunlight and external glass doors. The power input is AC 100-240 V at 50/60 Hz, and the display draws 154 W in on mode and 0.5 W in sleep mode. It carries energy efficiency class A and EMC Class B.
