Samsung QM55C 55" 4K UHD Smart Signage Display
PRODUCT DESCRIPTION
Samsung QM55C 55" 4K UHD Smart Signage Display - 3 Years Local Warranty
55-Inch 4K UHD Signage Rated for 24/7 Operation
The Samsung QM55C is a 55-inch Crystal UHD smart signage display from Samsung's QMC family. Its VA panel delivers 3,840 x 2,160 resolution at 500 nit typical brightness with 178-degree viewing angles, and it is rated for 24/7 operation for retail, F&B, corporate lobbies and transport hubs in Singapore.
Slim, Even-Bezel Design
Samsung lists a set depth of 28.5 mm and an even bezel of 11.5 mm on all sides, so the QM55C looks consistent in landscape or portrait orientation and sits close to the wall. A 200 x 200 mm VESA pattern accepts standard wall mounts, and Samsung offers matching optional mounts and stands.
Built-In Tizen 7.0 Player - No External Media Player Needed
Tizen 7.0 with 16 GB of flash memory plays content directly on the display. Wi-Fi, Bluetooth and an RJ-45 LAN port handle network connection, while 3 x HDMI 2.0 (HDCP 2.2) and 1 x DisplayPort 1.2 accept a PC, set-top box or other source when required.
Remote Management With Samsung VXT
Samsung VXT, Samsung's cloud-based content and remote device management solution (sold separately), lets your team schedule playlists, push updates and monitor screens across multiple sites from one console. RS-232 in/out and IR in support integration with existing control systems.
