QH75C

A 28.5 mm depth for reception walls and corridors

The QH75C is a 75-inch UHD 4K display from Samsung's QHC signage series. Its set depth is 28.5 mm and it measures 1682.3 x 960.4 mm, so it sits close to the wall in lobbies, corridors and meeting areas where a bulky screen would crowd the room. The bezel measures 13.4 mm on all four sides, which keeps the frame visually even when the screen is turned to portrait orientation for menus or vertical content.

Two mounting details help installers. The VESA pattern is 400 x 400 mm and sits centrally on the back, spreading the weight evenly and reducing the chance of the panel tilting when it is rotated to portrait. Samsung lists the WMN-B50SC wall mount and the STN-L6585C stand as optional accessories.

Picture, processing and connectivity

The panel is a VA type with a native 3,840 x 2,160 resolution, 700 nit typical brightness and a 4,000:1 contrast ratio. Its viewing angle is rated at 178 degrees horizontally and vertically, and the non-glossy frame and non-glare panel reduce reflections from windows and ceiling lights. The 72% NTSC colour gamut and 8 ms response time suit presentations, menus and video content.

Inputs include three HDMI ports with HDCP 2.2, one DisplayPort 1.2 input, two USB ports, an RJ45 network port, IR input, RS232 input and output, and a stereo mini-jack audio output. The built-in Wi-Fi and Bluetooth support wireless connections. The Quantum Processor Lite 4K upscales lower-resolution video to UHD. Tizen 7.0 runs the on-screen interface, with 16GB of flash memory. Samsung's SmartView+ enables wireless screen sharing, and Smart Calibration uses a Samsung mobile app to match colours across several displays.

Where the QH75C fits in Qatar

A hotel in West Bay can place the QH75C in a lobby or conference foyer to show arrival information and event schedules, and the 24/7 operation rating covers round-the-clock signage. A private school in Al Wakrah fitting out a corridor or staff room can run timetables and announcements over the network. A government office in Msheireb serving bilingual visitors can display wayfinding information. The operating range is 0 to 40 degrees Celsius, so the screen belongs in air-conditioned spaces, not sun-facing or unconditioned areas. Confirm room conditions with the SmartRooms Qatar team before installation.

Planning the installation

The set weighs 34.6 kg and the packed unit weighs 45.3 kg, so check that the wall, bracket and fixings are rated for the load. A free site survey lets our team check wall construction, power and network points, and sight lines before the panel goes up. Power draw is 275 W in on mode and 0.5 W in sleep mode. The Energy Efficiency Class is A, and the manufacturer notes ENERGY STAR 8.0 and EPEAT certifications. The data also lists EMC Class B and the 60950-1 and 62368-1 safety standards.
