QH43C

What the QH43C is built for

The Samsung QH43C is a 43-inch digital signage display for showing 4K content on a single wall-mounted screen that runs for long hours. It belongs to Samsung's Crystal UHD signage QHC range and focuses on a slim, tidy profile for tight spaces. It suits information, wayfinding and branding in corridors, lobbies and reception areas rather than interactive teaching or boardroom use.

Samsung rates the panel for 24/7 operation, so it suits locations where content must stay visible through the working day and beyond.

A slim, evenly framed body for walls and portrait displays

At 28.5 mm deep and 9.3 kg, the QH43C sits close to the wall, which keeps walkways clear and makes a lobby look neat. The bezel measures 11.5 mm on all four sides, so the frame stays balanced when the screen is turned to portrait for a directory or menu board. The 200 x 200 mm VESA holes are centred on the back, helping the weight distribute evenly on the bracket.

• Set size 969.5 x 557.8 x 28.5 mm (W x H x D)
• Even 11.5 mm bezel on all four sides
• Centred 200 x 200 mm VESA mounting pattern

Picture quality and connections that matter in practice

The 3,840 x 2,160 panel has a 0.245 mm pixel pitch, keeping small text and fine graphics sharp at close reading distances. The VA panel offers a typical brightness of 700 nit, a 4,000:1 contrast ratio and 178-degree horizontal and vertical viewing angles, so content stays readable from the side of a room. The non-glare panel is designed for brightly lit areas.

Connectivity covers three HDMI inputs (HDMI version 2), one DisplayPort 1.2 input, two USB ports, an IR input, RS232 in and out for control, and an RJ45 port for network connection. Built-in Wi-Fi and Bluetooth are included, and the unit runs Tizen 7.0 with 16GB of flash memory. HDCP 2.2 is supported. Audio leaves through a stereo mini jack, and no audio input is listed.

Where it fits in Qatar

A private school in Al Wakrah fitting out new corridors could mount several QH43C units to show timetables, announcements and campus information, with the slim depth keeping walkways passable.

A clinic in Doha's Msheireb or Al Sadd area might use one in its waiting room for queue and directional content. Its operating range is 0 to 40°C, so the screen should sit in an air-conditioned space away from windows and open entrances, where outdoor summer temperatures can pass 45°C.

A hotel or serviced apartment building in The Pearl or West Bay could place a unit by the lift lobby to show event schedules and floor plans.

Planning the installation

Survey the wall before ordering. The 9.3 kg panel needs a bracket that matches the 200 x 200 mm pattern, and the position should be checked against the nearest 240 V outlet and the cable route behind the 28.5 mm depth. SmartRooms Qatar offers free site surveys and professional installation.

Power input is rated at 100 to 240 V, 50/60 Hz, with 132 W typical draw in on mode and 0.5 W in sleep mode. Samsung lists the WMN-B50SC wall mount and STN-L4355C stand as optional accessories. The slim wall mount mentioned in its product information and the Samsung VXT CMS remote management service are both sold separately. Multi-unit projects for schools and government bodies can be ordered on a purchase order (LPO) or through a government tender.
