QM43R-B

A 43-inch 4K panel built for continuous signage

The QM43R-B is a 43-inch display with an IPS panel and a 3,840 x 2,160 resolution, giving four times the pixels of Full HD on a screen that fits a reception wall, a corridor or a meeting-room entrance. Typical brightness is 500 nit, and the non-glare surface helps text and images stay readable under ceiling lights and in rooms with daylight. The panel covers 92% of the DCI-P3 colour gamut and is rated at a 1,200:1 contrast ratio, so brand colours and photography look richer than on basic commercial screens.

Viewing angles are rated at 178 degrees horizontally and vertically, so people approaching from the side of a lobby can still read a menu or a wayfinding message. The 8 ms response time suits moving video and animated content in promotional loops.

Upscaling, connections and built-in software

The Crystal Processor 4K upscales lower-resolution material so that an older HD clip or a legacy slide file plays at UHD-level quality, with on-screen text and images made clearer in the process. The connection set includes:

• Two HDMI inputs (HDMI version 2) with HDCP 2.2 support
• One DisplayPort input (version 1.2)
• Two USB ports, an IR input and an RJ45 network port
• RS232 in and out ports for serial control
• Stereo audio input and a stereo mini-jack audio output
• Built-in Wi-Fi

The display runs Tizen 4.0 with 8GB of flash memory. Samsung Workspace, secured with Knox, provides wireless cloud access and control of a PC without a physical cable, which helps meeting rooms where presenters share from laptops. A cable guide keeps wiring out of sight when the back of the panel is visible, for example in a retail aisle.

Where the QM43R-B fits in Qatar

In a clinic or hospital waiting area in Doha, one panel can show queue numbers, health guidance and service information without a screen for each department. A shopping outlet in Lusail could place it at the entrance to promote offers, with the cable guide hiding the wiring. In the Industrial Area, a logistics company could use it in a reception lobby to display visitor instructions and shift notices.

The operating range of 0 to 40 degrees Celsius means this model belongs in an air-conditioned indoor space. Summer temperatures above 45 degrees Celsius are common in Qatar, so a sunlit external wall or an unventilated kiosk is not a suitable location.

Planning the mount, power and paperwork

The panel uses a 200 x 200 mm VESA pattern. Samsung lists the WMN4070SG and WMN750ME wall mounts and the STN-L4355G stand as options. The set weighs 10 kg, and the packed unit weighs 13.3 kg. Dimensions are 967.5 x 557.7 x 48.3 mm with bezels of 9.2 mm on the top, left and right and 11.2 mm at the bottom. It runs on AC 100 to 240 V at 50/60 Hz, drawing 110 W in on mode and 0.5 W in sleep mode.
