55LS75C-M

What this discontinued 55-inch LG display is built for

The LG 55LS75C-M belongs to the LS75C line of standard signage displays and measures 54.64 inches across the diagonal. The manufacturer has discontinued this model, so this page is written for organisations that already run one, buyers comparing it with newer panels, and anyone who needs a current equivalent. Our team can quote a compatible replacement that matches the mounting and content setup you already have.

Panel and physical facts that shape the installation

The panel uses a 1,920 x 1,080 Full HD resolution and a typical brightness of 700 cd/m². Its even 7.4 mm bezel on all four sides lets several units sit side by side for a tidy multi-screen wall. The head unit measures 1,230 x 714 x 32 mm and weighs 20.7 kg, and it uses a 400 x 400 mm VESA pattern, so a compatible wall bracket is needed. The LSW440S wall mount and ST-200T stand are listed as optional accessories.

Typical power draw is 140 W, and the Smart Energy Saving mode is rated at 100 W. Certifications listed for this model include UL, cUL, CB, TUV and KC for safety, and FCC Class A, CE and KCC for EMC. The source data does not give an operating temperature range, so confirm the environment with the SmartRooms Qatar team before placing the display near windows, in a dusty lobby or in any position exposed to outdoor conditions.

Connecting content: inputs, networking and media players

• Two HDMI inputs, one DisplayPort input, DVI-D and an audio input
• An OPS slot, with MP500 and MP700 external media players as alternatives
• RS232C in and out, RJ45, USB 3.0 and an IR or light sensor for control

Networking features include support for RTSP/RTP, MMS, HLS and MPEG-2 TS video streams, HTTPS for encrypted communication with the content server, and proxy server support. SuperSign W handles content management and SuperSign C handles control and monitoring. The Group Manager feature lets content be created, distributed and controlled without a dedicated PC or server, which can simplify smaller sites. The optional AN-WF500 Wi-Fi USB dongle is required for the BEACON feature with Bluetooth Low Energy, so confirm which wireless functions your setup needs before ordering.

Where this model fits in Qatar

A private school in Al Wakrah refitting a corridor might mount one or two of these panels where students gather between lessons, using picture-by-picture layouts to show a timetable and announcements together. A ministry reception in Msheireb could use a single panel for visitor directions and service information. A retail outlet in The Pearl could run promotions from a media module in the OPS slot. At 55 inches, the model suits corridors, reception areas and small meeting spaces more than large lecture halls.

What to plan before you order

Measure the wall and check the 400 x 400 mm VESA pattern before ordering a mount. Because the head unit weighs 20.7 kg, a site survey helps confirm wall structure, cable routes and viewing height. SmartRooms Qatar offers free site surveys across the municipalities we serve. For schools or government offices ordering several units, a purchase order (LPO) or tender reference can be included in the quotation request, and quotations are usually returned within one working day.

Because this model is discontinued, ask for a quote that compares a current equivalent with the specification you need. Request a quote from SmartRooms Qatar and tell us your wall type, content source and quantity.
