Samsung QH43C 43" UHD 4K Commercial Monitor
PRODUCT DESCRIPTION
Samsung QH43C 43" Crystal UHD Commercial Display (LH43QHCEBGCXXS) - Local Warranty
700-Nit Panel for Shop Windows and Bright Lobbies
The QH43C is rated at 700 nit typical brightness, which is the figure that decides whether a screen still reads at 2pm in a glazed Orchard Road shopfront or a naturally lit office reception. Standard meeting-room panels at 350 nit wash out in those positions; the QH43C holds its contrast at 4,000:1 with a VA panel and 25% haze glass that scatters overhead downlights instead of mirroring them. At 43 inches it suits queue-line menu boards, lift-lobby directories and counter-top promotional screens where the viewer stands within two or three metres of the glass.
24/7 Duty Rating for Signage That Never Switches Off
Samsung rates the QHC series for 24 hours a day, seven days a week. That matters for wayfinding in a building that never closes, for transport and hospital corridors, and for retail windows that keep running after the shutters come down. A consumer television or a 16/7 display left on continuously will age unevenly and falls outside its intended duty cycle. The QH43C also carries an on-board temperature sensor that lets the display protect itself if an enclosure or a recessed joinery pocket runs hotter than expected, so unattended sites stay up.
Tizen 7.0 On Board - No External Media Player to Buy
The display runs Tizen 7.0 on a 1.6GHz quad-core processor with 16GB of internal storage, so a playlist of images and video can sit on the screen itself. That removes a media player, its power supply and its mount from every position in the estate. Content is published and scheduled over the network with Samsung VXT or MagicINFO, and dual-band Wi-Fi plus Gigabit Ethernet mean a screen in a heritage shopfront with no data point can still be reached. Director Mode, DICOM Simulation Mode and Smart Calibration are supported for specialist rooms.
28.5mm Slim Build for Flush Mounting in Retail and Boardrooms
At 28.5mm deep, 969.5 x 557.8mm and 9.3kg, the QH43C sits close to the wall and is light enough for a single installer on a standard 200 x 200mm VESA bracket. The 11.5mm even bezel is the same width on all four sides, so a portrait-mounted unit looks intentional rather than rotated. Landscape and portrait are both supported. For boardrooms and classrooms that means a screen that reads as architecture rather than equipment; for retail it means the joinery reveal can be cut tight without a deep recess.

Compatibility & Installation
Mounting
The QH43C uses a 200 x 200mm VESA pattern and weighs 9.3kg, so it works with standard flat and tilting commercial brackets as well as recessed joinery pockets. Depth is 28.5mm. Both landscape and portrait orientation are supported, and the 11.5mm bezel is even on all four sides so a rotated unit still looks square. Allow clearance for the rear connector bay and for airflow; the display carries a temperature sensor and is specified for an ambient range of 0°C to 40°C at 10-80% relative humidity, non-condensing.
What it connects to
Three HDMI 2.0 inputs with HDCP 2.2 and one DisplayPort 1.2 input cover laptops, room systems, video conferencing codecs, media players, cameras and matrix switchers at full 4K. Two USB 2.0 ports handle local playback from a stick and power for small peripherals. Audio can be taken out over the stereo mini jack to a ceiling or soundbar amplifier, or played on the built-in 10W + 10W speakers. RS232C in and out plus IR in let the display join a control system such as Crestron, Extron or AMX for scheduled power and input switching.
Network and content management
Tizen 7.0 runs the signage player on the screen itself, so most deployments need no external box. Content is authored, scheduled and monitored centrally with Samsung VXT or MagicINFO, licensed separately. Connect over the RJ45 Gigabit port where structured cabling exists, or over dual-band 2.4GHz / 5GHz Wi-Fi where it does not. Bluetooth is on board. Sixteen gigabytes of internal storage (around 10GB usable) hold a local playlist so the screen keeps playing if the network drops. Director Mode, DICOM Simulation Mode and Smart Calibration are available for colour-critical and clinical viewing rooms.

Frequently Asked Questions - Samsung QH43C
Why choose the 700-nit QHC over the QMC or QBC series?
Brightness is the deciding factor. The QHC is rated at 700 nit, the QMC range at 500 nit and the QBC range at 350 nit. A 350-nit panel is fine for an internal meeting room with blinds; it will look grey in a shopfront, a glazed atrium or a lobby with skylights. The QHC also carries a 24/7 duty rating, so it is the right choice where the screen faces daylight, runs long hours, or both.
Can the QH43C really run 24 hours a day?
Yes. Samsung rates the QHC series for 24/7 operation, which is a design and warranty statement about the panel, power supply and thermal management, not just a marketing line. It also has a built-in temperature sensor for enclosed installations. A 16/7 display or a consumer television used the same way is running outside its intended duty cycle.
Does it need an external media player?
Usually not. The QH43C runs Tizen 7.0 with a 1.6GHz quad-core processor and 16GB of internal storage, so it plays a scheduled playlist on its own and is managed remotely through Samsung VXT or MagicINFO. An external player is only needed for unusual content types or a third-party CMS that has no Tizen application.
Can it be mounted in portrait?
Yes. Samsung specifies both landscape and portrait orientation for this model, and the 11.5mm bezel is even on all four sides so a rotated screen does not look lopsided. Use a bracket rated for portrait on the 200 x 200mm VESA pattern and allow clearance for the rear connector bay.
Is the QH43C a touchscreen?
No. This is a non-touch signage display. For interactive wayfinding or a collaboration board you would look at a touch-enabled model or add a third-party touch overlay sized to a 43-inch panel.
What do the letters in QH43C and LH43QHCEBGCXXS mean?
QH is the high-brightness signage family, 43 is the screen size in inches, and C is the generation. In the full part number LH43QHCEBGCXXS, the trailing XXS identifies the Singapore market model, which is what SourceIT supplies with a local warranty and a Singapore power cord.
How does the QH43C differ from the 55-inch QH55C?
Only in size and the numbers that follow from it. Both are 700 nit, 4K UHD, 24/7, Tizen 7.0 with the same port set. The QH55C is 1,237.9 x 708.8mm and 16.9kg and draws 187W, against 969.5 x 557.8mm, 9.3kg and 132W for the QH43C. Both use a 200 x 200mm VESA pattern.
What warranty and invoicing do I get from SourceIT?
Every unit is supplied with the local Singapore warranty and a GST invoice, which is what your finance team needs for input tax claims and what facilities needs for a valid service entitlement in Singapore.
