Samsung QB65C 65" 4K Smart Commercial Display
PRODUCT DESCRIPTION
Samsung QB65C 65" UHD 4K Crystal Signage Display (LH65QBCEBGCXXS) - Local Warranty
65 Inches of 4K for Lobbies, Atriums and Large Meeting Rooms
The QB65C is the size that starts to carry a room. In a corporate atrium, a hotel lobby, a showroom or a large boardroom it reads clearly from six to eight metres while its 3,840 x 2,160 panel and 0.372 mm pixel pitch keep agendas, dashboards and fine print sharp for anyone standing in front of it. A 4,000:1 contrast ratio and NTSC 72% colour gamut hold brand colour under lobby downlights, and an 8 ms response time keeps showreels and animated wayfinding smooth rather than smeared.
MagicINFO and Samsung VXT Content Management Without a Player
Content management runs on the display itself. Tizen 7.0 with a CA53 1.3 GHz quad-core processor and 8 GB of onboard storage plays scheduled media locally, and Samsung VXT handles cloud scheduling, playlist versions and multi-site rollouts from a browser. Screens on a MagicINFO estate are supported too. The practical result for a Singapore operator with several sites is that a promotion change is published once and lands on every panel, and no branch needs a media player cabled behind the screen or an IT visit to reload a USB stick.
16/7 Commercial Rating and SmartThings Pro Remote Oversight
Samsung rates this panel for 16 hours a day, seven days a week, the duty cycle a lobby or retail floor actually runs. SmartThings Pro adds the management half: remote power scheduling, status monitoring and firmware oversight for every display in the fleet from one console. A screen that has dropped off the network or failed to wake shows up in the console rather than in a complaint, and overnight power-down schedules cut the 187 W on-mode draw to a 0.5 W sleep state across the estate.
21.5 kg, 28.5 mm Deep, 400 x 300 VESA
Despite the 65-inch diagonal the chassis is only 28.5 mm deep and the set weighs 21.5 kg, so it mounts flush on a slim-fit bracket without a deep recess or a structural rework. The 400 x 300 VESA pattern is a standard commercial fixing, and the 11.5 mm even bezel supports portrait installation for a tall directory or promotional pillar. Samsung's STN-L6585C stand and WMN-B50SC slim-fit wall mount are available separately for floor-standing or flush-mount requirements.

Compatibility & Installation
Mounting and orientation
The QB65C uses a 400 x 300 mm VESA mount pattern with the fixing holes centred on the back of the set, and the chassis is 28.5 mm deep so it sits close to the wall on a slim-fit bracket. Landscape and portrait are both supported and the bezel is even on all four sides, so a rotated installation looks intentional. Set weight is 21.5 kg - check that any bracket you already own is rated for that load and, if you are rotating the screen, for portrait use. Samsung's WMN-B50SC slim-fit wall mount and STN-L6585C stand are available separately and we can quote either with the display.
What it connects to
Three HDMI 2.0 inputs accept laptops, room systems, video conferencing codecs, cameras, Blu-ray and set-top sources at up to 3,840 x 2,160. Two USB 2.0 ports take local media for playback straight from a drive. Audio leaves through a stereo mini jack to a sound bar or a ceiling system where the 10 W x 2 built-in speakers are not enough for the room. For wired control by an AV integrator or a building management system there is RS232C in and out plus an IR input for a repeater, which is what you need when the panel is mounted behind a fascia.
Network and content management
The display runs Tizen 7.0 with 8 GB of onboard storage, so scheduled content plays without an external media player. Connect over RJ45 or dual-band Wi-Fi at 2.4 GHz or 5 GHz. Samsung VXT is the current cloud CMS for scheduling, playlists and multi-site publishing, and the panel is ready for a MagicINFO estate as well. SmartThings Pro covers the device side: remote power scheduling, on and off status, and firmware oversight across the fleet from one console. Smart Calibration lets you match colour across several panels from a mobile device.
Other Samsung QBC displays it pairs with
QBC panels share the same platform, so a mixed-size estate is managed as one fleet from the same console. A counter or kiosk position usually takes the QB24C, a shelf edge or door plate the QB13C, and a lobby or feature wall one of the larger sizes. Ask us and we will map the sizes to your floor plan.

Frequently Asked Questions — Samsung QB65C
Is the QB65C meant to run all day, every day?
Samsung rates the QB65C for 16 hours a day, seven days a week. That covers the opening hours of a retail unit, a lobby, a clinic or a corporate floor with margin. It is not a 24/7 rating, so for a control room, a transport hub or any site that never switches the screen off, ask us about Samsung's 24/7-rated signage series instead - we would rather put the right panel on the wall than have a 16/7 display run outside its specification.
Do I need a separate media player with it?
No. The QB65C runs Tizen 7.0 on a CA53 1.3 GHz quad-core processor with 8 GB of internal storage, so it plays scheduled content by itself. Samsung VXT handles cloud scheduling across sites, and it works on a MagicINFO estate as well. You would only add an external player if you need an application the platform does not run, such as a bespoke interactive front end.
Can it be mounted in portrait?
Yes. Portrait orientation is supported, and the bezel is even on all four sides so it looks correct rotated. It uses a 400 x 300 mm VESA pattern; make sure the bracket you choose is rated for portrait use and for the 21.5 kg set weight, as not every landscape bracket is.
Is 350 nit bright enough for my space?
350 nit is specified for indoor commercial lighting - malls, lobbies, receptions, showrooms, meeting rooms and hospitality areas. It is not specified for a window position facing direct sunlight, where reflected daylight will beat it. If the screen faces a shopfront or a fully glazed facade, tell us the orientation and we will quote a higher-brightness Samsung series instead.
What do the letters in LH65QBCEBGCXXS actually mean?
Reading it Samsung's way: LH marks a commercial display, the two digits are the screen size, QBC is the series, and the trailing letters identify the panel variant and the regional model. XXS is the code for Singapore stock, which is what matters for local warranty and support - a set carried in from another market will carry that market's code and its warranty stays there.
How many sources can I leave plugged in?
Three, on HDMI 2.0, plus two USB 2.0 ports for local media. Network is RJ45 or dual-band Wi-Fi, and there is Bluetooth as well. For integrator control there is RS232C in and out and an IR input, so a room controller or building management system has a wired path to the display.
How does it compare with the QB75C?
Same panel technology, same Tizen 7.0 platform, same 350 nit and 4,000:1 specification, same port set - the difference is diagonal, physical size, weight and power draw. Choose on viewing distance and available wall first. The QB65C draws 187 W typical in on mode; the larger model draws more, which is worth checking against the circuit if you are hanging several.
What warranty comes with it in Singapore?
Every QB65C we sell carries local Singapore warranty and ships with a GST invoice. That means support is handled here rather than through a grey-import channel, and your finance team gets a compliant tax invoice for the purchase.
