Samsung QB43C 43" UHD 4K HDR Commercial Monitor
PRODUCT DESCRIPTION
Samsung QB43C 43" UHD 4K Crystal Signage Display (LH43QBCEBGCXXS) - Local Warranty
4K Clarity at Arm's Length for Counters, Lifts and Queue Lines
At 43 inches the QB43C sits at the size most Singapore sites reach for when the viewer is close: a service counter, a lift lobby, a queue line or a shop window facing the walkway. Its 3,840 x 2,160 panel packs a 0.245 mm pixel pitch, so price points, terms and conditions and fine wayfinding type stay sharp from a metre away rather than breaking up. A 4,000:1 contrast ratio and 350 nit output keep artwork readable under the fluorescent and downlight levels typical of malls, clinics and office receptions.
16/7 Commercial Duty Instead of a Consumer Panel
This is a commercial signage panel rated by Samsung for 16 hours a day, seven days a week. That rating matters because a consumer television run on shop hours will age its panel and void its warranty, while the QB43C is built and warranted for exactly that pattern. Components, thermal design and firmware are specified for unattended daily operation, and the display returns to its scheduled content after a power event without someone walking over to press a button. For mall tenancies, clinics and branch offices on a 7am to 11pm cycle, that is the whole point.
No Media Player to Buy, Rack or Maintain
Tizen 7.0 runs on a CA53 1.3 GHz quad-core processor with 8 GB of onboard storage, so the QB43C plays your content by itself. There is no small-form-factor PC to specify, no player to cable behind the screen, and no second device to patch or replace. Schedule from Samsung VXT in the cloud, or push a playlist over the network, and the panel handles playback on its own. For a rollout across several branches that removes a whole hardware line item and a whole class of site visit from the project.
Three HDMI Inputs and a 28.5 mm Profile for Tight Installs
Three HDMI 2.0 inputs mean the signage playlist, a laptop for a walk-up presentation and a room system can all stay connected at once, with no switcher and no swapping cables. Two USB 2.0 ports, RJ45, dual-band Wi-Fi, Bluetooth and RS232C in and out cover both network and integrator control. The chassis is 28.5 mm deep with an 11.5 mm even bezel, so on a 200 x 200 VESA slim mount it sits close to the wall - which is what makes it usable in a corridor, a lift lobby or a shallow shopfront recess.

Compatibility & Installation
Mounting and orientation
The QB43C uses a 200 x 200 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 8.8 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-L4355C 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 QB43C
Is the QB43C meant to run all day, every day?
Samsung rates the QB43C 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 QB43C 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 200 x 200 mm VESA pattern; make sure the bracket you choose is rated for portrait use and for the 8.8 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 LH43QBCEBGCXXS 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 QB50C?
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 QB43C draws 121 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 QB43C 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.
