Samsung QH65C 65" UHD 4K Commercial Monitor
PRODUCT DESCRIPTION
Samsung QH65C 65" Crystal UHD Commercial Display (LH65QHCEBGCXXS) - Local Warranty
700-Nit Panel That Still Reads Across a Daylit Atrium
A 65-inch screen is usually specified because people need to read it from ten metres away, and at that distance ambient light is the enemy rather than pixel count. The QH65C is rated at 700 nit typical with a 4,000:1 contrast ratio on a VA panel, and 25% haze glass that scatters skylights and downlights instead of mirroring them. In a glazed atrium, a mall concourse or a hotel porte-cochere a 350-nit panel simply greys out. At 178° horizontal and vertical the image also holds for viewers approaching from the side.
24/7 Duty Rating for Wayfinding and Transport Environments
Samsung rates the QHC series for 24 hours a day, seven days a week, which is what a directory board in a hospital, an interchange or a 24-hour serviced-apartment lobby actually does. The rating covers the panel, power supply and thermal handling rather than being a marketing claim, and an on-board temperature sensor lets the display protect itself where it sits in joinery or an enclosure. Put a 16/7 display or a consumer television in the same position and it will age unevenly and fall outside its intended duty cycle.
Tizen 7.0 On Board - No Player Box Behind the Screen
The QH65C runs Tizen 7.0 on a 1.6GHz quad-core processor with 16GB of internal storage, so the signage player lives inside the display. On a 65-inch screen mounted high in a lobby that is significant: there is no separate box to mount, power and service at height. Playlists are published, scheduled 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 on a 400 x 300mm VESA Pattern
The QH65C measures 1,456.8 x 831.9 x 28.5mm and weighs 22.7kg on a 400 x 300mm VESA pattern, so a two-person lift onto a standard commercial bracket sits the panel close to the wall. The 11.5mm bezel is even on all four sides, so a portrait-mounted unit in a wayfinding column reads as deliberate rather than rotated, and both orientations are supported. In boardrooms and lecture theatres the slim depth means the screen finishes flush with joinery instead of projecting into the room.

Compatibility & Installation
Mounting
The QH65C uses a 400 x 300mm VESA pattern and weighs 22.7kg, so it needs a bracket rated for that pattern and a two-person lift. Note that this differs from the 200 x 200mm pattern on the 43, 50 and 55-inch models, so brackets are not interchangeable across the range. Depth is 28.5mm and the panel measures 1,456.8 x 831.9mm. Landscape and portrait are both supported. 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, which matters most on a large panel mounted at height where a separate player box would be awkward to service. Content is authored, scheduled and monitored centrally with Samsung VXT or MagicINFO, licensed separately. Connect over the RJ45 Gigabit port or dual-band 2.4GHz / 5GHz Wi-Fi; 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 QH65C
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 QH65C 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 QH65C 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 portrait-rated bracket on the 400 x 300mm VESA pattern and allow clearance for the rear connector bay.
Is the QH65C 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 65-inch panel.
What do the letters in QH65C and LH65QHCEBGCXXS mean?
QH is the high-brightness signage family, 65 is the screen size in inches, and C is the generation. In the full part number LH65QHCEBGCXXS 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 QH65C differ from the 75-inch QH75C?
Both are 700 nit, 4K UHD, 24/7 and Tizen 7.0 with the same port set. The QH75C is 1,682.3 x 960.4mm, 34.6kg, draws 275W, has a 13.4mm bezel and uses a 400 x 400mm VESA pattern. The QH65C is 1,456.8 x 831.9mm, 22.7kg, draws 203.5W, has an 11.5mm bezel and uses 400 x 300mm, so budget for a different bracket and a heavier lift if you move up.
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.
