Samsung QM55B-T 55" 4K UHD Digital Signage
PRODUCT DESCRIPTION
Samsung QM55B-T 55" 4K UHD Touch Signage (LH55QMBTBGCXXY) - Local Warranty
24/7-Rated Touch Signage for Kiosks and Public Spaces
The QM55B-T is rated for 24/7 operation, which is the specification that separates commercial signage from a meeting-room display. A self-service kiosk in a mall, a wayfinding point in a hospital lobby or a check-in station in a hotel cannot be switched off at six o'clock, and a panel not built for continuous duty will not survive it. The B in QM55B-T marks the generation, replacing the earlier QM55R-T. Supplied locally by SourceIT with Singapore warranty and a GST invoice on every unit.
500-Nit Panel for Bright Lobbies and Shop Floors
Five hundred nits is the useful brightness level for an indoor commercial space with daylight coming in — a retail floor with a glazed frontage, an airport concourse, a bank branch or a hotel lobby. At 400 nits with the touch glass in place, the picture still holds up under ambient light where a consumer panel would wash out. Contrast is 4,000:1, the viewing angle is 178 degrees in both axes so the screen reads from an approach angle, and colour gamut covers 92% DCI-P3 for brand-accurate product imagery.
Capacitive Touch That Behaves Like a Phone Screen
Capacitive touch is the right choice for public-facing self-service, because it is what the public already knows. Swipe, pinch and tap work the way they do on a phone, so a customer browsing a product catalogue, choosing a meal or looking up a unit number does not need instruction. The 8ms panel response keeps the interface feeling immediate rather than laggy. For product configurators, interactive directories, queue-ticket stations and hospitality check-in points, that familiarity is what keeps people using the screen instead of walking to a counter.
Tizen 6.5 and MagicINFO for Estates of Screens
Tizen 6.5 runs on the display itself, so a single-screen deployment needs no external player and no PC in the cabinet. For an estate — a retail chain, a campus, a hotel group — MagicINFO is supported for central scheduling and content updates across sites, with the licence purchased separately. Three HDMI 2.0 inputs and a DisplayPort 1.2 input cover any external source you do add, RJ45 and Wi-Fi handle the network, and RS232 in and out allows daisy-chained control from a building management or AV control system.

Compatibility & Installation
Mounting and orientation
The QM55B-T uses a 200 x 200mm VESA pattern and weighs 26.9kg, so specify a bracket or kiosk enclosure rated above that at 200 x 200. The small pattern suits slim wall mounts and freestanding kiosk housings, which is how most touch signage is deployed. Samsung lists an Auto Level feature for orientation, and the QMB signage family is designed for both landscape and portrait installation — confirm the intended orientation with SourceIT before ordering so the mount and any enclosure are specified correctly for a touch application.
What it connects to
Three HDMI 2.0 inputs and a DisplayPort 1.2 input take a media player, a kiosk PC, a point-of-sale terminal or a laptop for commissioning. Two USB ports handle local content and peripherals such as a scanner or a card reader in a self-service build. RJ45 gives a wired network connection, which is the right choice for an unattended public installation, with Wi-Fi and Bluetooth also on board. RS232 in and out allows daisy-chained control from a building management or AV control system, and audio out on a stereo mini jack feeds external speakers.
Network and content management
Tizen 6.5 runs on the display itself, so a single screen needs no external player. For multi-site estates, MagicINFO is supported for central scheduling, playlist management and remote content updates across a chain of stores, a campus or a hotel group; the MagicINFO licence is purchased separately from the display. A wired network connection is recommended for any screen expected to run unattended around the clock.
Accessories and related products
Touch signage is normally paired with a kiosk enclosure or a slim wall mount rather than Samsung's interactive-whiteboard accessories — the Flip stands, wall mounts and connectivity trays are specified for the Flip range and do not fit the QM series. Where an installation calls for a smaller touch point at the same generation family, see the QB13R-T, QB24R-T, QM32R-T and QM43B-T listed in the range table below.

Frequently Asked Questions — Samsung QM55B-T
What do the letters in the model number mean?
QM is Samsung's 4K signage line, 55 is the panel size in inches, B is the generation and the -T suffix marks the touch version. So a QM55B-T is a 55-inch B-generation 4K signage display with touch, and the earlier equivalent was the QM55R-T. Samsung uses generation letters the same way across its interactive ranges — in the Flip family, for example, R is Flip 2, A is Flip 3, B is Flip Pro and F is the current WMFX generation.
Is this touch or non-touch?
Touch. The QM55B-T uses a capacitive touch layer, which behaves like a phone or tablet screen — swipe, pinch and tap — so members of the public use it without instruction. The non-touch QM55B is the same panel family without the touch layer, for signage that only plays content.
Can it run 24 hours a day?
Yes. The QM55B-T is rated for 24/7 operation, which is what an unattended kiosk, a wayfinding point or a transport information screen needs. By contrast, Samsung's interactive whiteboards such as the Flip range are rated for 16/7 and are not the right choice for continuous public duty.
Do I need an external media player?
Not for a straightforward deployment. Tizen 6.5 runs on the display, so it plays scheduled content on its own. You would add a player or kiosk PC only where the application needs software the display cannot run — a bespoke self-service application or a point-of-sale integration, for example.
Is MagicINFO included?
MagicINFO is supported by the display, but the licence is purchased separately. For a single screen you may not need it; for an estate across several sites it is what makes central scheduling and remote content updates practical.
Can it be installed in portrait?
The QMB signage family is designed for both landscape and portrait installation and the display includes an Auto Level feature for orientation. Because a touch installation also has to suit how people reach the screen, confirm the intended orientation with SourceIT before ordering so the mount or kiosk enclosure is specified correctly.
How bright is it, and will that work in my space?
500 nits without the touch glass and 400 nits with it. That suits an indoor commercial space with daylight — a retail floor, a lobby, a concourse or a branch. For a shop window facing direct sun you need a high-brightness or outdoor-rated model instead; ask SourceIT which Samsung range fits that position.
What warranty and invoice do I get from SourceIT?
Every QM55B-T sold by SourceIT comes with local Singapore warranty and a GST invoice on the unit. Support and any warranty claim go through a Singapore supplier rather than an overseas RMA.
