Samsung QH55C 55" UHD 4K Commercial Monitor
PRODUCT DESCRIPTION
Samsung QH55C 55" Crystal UHD Commercial Display (LH55QHCEBGCXXS) - Local Warranty
700-Nit Panel for Shop Windows and Daylit Lobbies
Fifty-five inches is the workhorse size for retail windows, lift lobbies and hotel reception walls, and those are exactly the positions where brightness decides whether the screen works. The QH55C is rated at 700 nit typical with a 4,000:1 contrast ratio on a VA panel, and 25% haze glass that scatters downlights rather than reflecting them back at the viewer. A 350-nit meeting-room panel in the same window will look washed out by mid-morning. At 178° in both axes the image holds for customers walking past at an angle rather than standing square on.
24/7 Duty Rating for Estates That Never Switch Off
Samsung rates the QHC series for 24 hours a day, seven days a week. In practice that covers transport interchanges, hospital corridors, serviced-apartment lobbies and retail windows that keep running after closing. It is a design statement about the panel, power supply and thermal handling, not a marketing line, and it is the reason a QHC belongs in an unattended position where a consumer television would age unevenly. An on-board temperature sensor lets the display protect itself if a joinery pocket or an enclosure runs warmer than the design assumed.
Tizen 7.0 On Board - One Less Box Per Screen
The QH55C runs Tizen 7.0 on a 1.6GHz quad-core processor with 16GB of internal storage, so the signage player lives inside the screen. Across a twenty-screen estate that removes twenty media players, twenty power supplies and twenty mounting plates, along with the cabling and the failure points that come with them. Playlists are published and monitored centrally with Samsung VXT or MagicINFO, over Gigabit Ethernet or dual-band Wi-Fi. Director Mode, DICOM Simulation Mode and Smart Calibration are supported where colour accuracy or clinical viewing matters.
28.5mm Slim Build for Flush Mounting in Retail and Boardrooms
The QH55C measures 1,237.9 x 708.8 x 28.5mm and weighs 16.9kg on a 200 x 200mm VESA pattern, so it mounts flat and close to the wall on standard commercial brackets. The 11.5mm bezel is even on all four sides, which means a portrait installation reads as deliberate rather than rotated, and both orientations are supported. For boardrooms and classrooms the result is a screen that looks like part of the architecture; for retail joinery it means the reveal can be cut tight without a deep recess.

Compatibility & Installation
Mounting
The QH55C uses a 200 x 200mm VESA pattern and weighs 16.9kg, so it suits standard flat, tilting and pull-out commercial brackets as well as recessed joinery. Depth is 28.5mm and the panel measures 1,237.9 x 708.8mm. Landscape and portrait are both 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 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, 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 go out over the stereo mini jack to a ceiling or soundbar amplifier, or play on the built-in 10W + 10W speakers. RS232C in and out plus IR in let the display join a Crestron, Extron or AMX control system for scheduled power and input switching.
Network and content management
Tizen 7.0 runs the signage player inside the screen, so most sites 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 also on board. Sixteen gigabytes of internal storage (around 10GB usable) hold a local playlist so the screen keeps playing through a network outage. Director Mode, DICOM Simulation Mode and Smart Calibration are available for colour-critical and clinical viewing rooms.

Frequently Asked Questions - Samsung QH55C
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 QH55C 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. It also has a built-in temperature sensor for enclosed installations. A 16/7 display or a consumer television used the same way would be running outside its intended duty cycle.
Does it need an external media player?
Usually not. The QH55C 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 with 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 QH55C 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 55-inch panel.
What do the letters in QH55C and LH55QHCEBGCXXS mean?
QH is the high-brightness signage family, 55 is the screen size in inches, and C is the generation. In the full part number LH55QHCEBGCXXS 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 QH55C differ from the 65-inch QH65C?
Only in size and the numbers that follow from it. Both are 700 nit, 4K UHD, 24/7 and Tizen 7.0 with the same port set. The QH65C is 1,456.8 x 831.9mm, 22.7kg and draws 203.5W on a 400 x 300mm VESA pattern, against 1,237.9 x 708.8mm, 16.9kg, 187W and 200 x 200mm for the QH55C, so the bracket is not interchangeable.
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.
