LG 55XS4P 55-inch Window Facing Display

Overview

The LG 55XS4P is a 55-inch full HD display built for screens behind glass that face daylight. It is rated at 4,000 nits typical brightness, so content stays readable through shopfronts and lobby windows. It runs webOS 6.0, supports 24/7 operation and carries a 0 to 40°C operating range without direct sunlight. Retailers, banks and hotels across Qatar can manage content remotely.

What the LG 55XS4P does behind glass

The LG 55XS4P is a 55-inch display designed for locations where the screen sits behind a window and faces daylight. Its 1920 x 1080 IPS panel uses direct backlighting and is rated at 4,000 nits typical with a 3,200 nit minimum. That margin keeps offers, wayfinding and public information visible when sunlight falls on the glass. The panel is rated for 24/7 operation with a typical lifetime of 50,000 hours.

Brightness, heat and the facts to check

Brightness only helps if the unit runs inside its rated environment. The operating range is 0 to 40°C without direct sunlight and 0 to 30°C in direct sunlight, with humidity from 10 to 80 percent. Summer temperatures in Doha regularly pass 45°C outdoors, so a window position needs a ventilated or air-conditioned space and a sun-exposure check before ordering. The built-in fan and the conformal coating on the circuit and power boards help protect components from dust, metal particles and moisture. Upgraded Quiet Mode lowers output to 2,500 nits with minimal fan noise, which suits displays near seating areas.

Content control and connectivity

The unit runs webOS 6.0 on a quad-core processor that handles several tasks at once, so a separate media player is not needed for basic playback. Built-in Wi-Fi and Bluetooth, an RJ45 LAN port and 16GB of internal eMMC storage give IT teams several ways to connect. The listed software includes SuperSign CMS, SuperSign Control+, SuperSign Cloud and Connected Care. A web-based content solution lets managers view current and historical data from mobile devices and adjust the unit in real time.

Where it fits in Qatar

Retail storefronts in West Bay or The Pearl: daytime promotions that stay readable to passers-by.
Bank and government counters with glazed frontages: wayfinding and service information visible from outside.
Hotel lobbies and serviced apartment entrances: arrivals, events and service information shown around the clock.

Planning the installation

The head weighs 26.0 kg and the packed unit weighs 31.2 kg, so the wall or frame must be checked before fixing. The monitor measures 1235.5 x 709.4 x 85.4 mm and uses a 600 x 400 VESA mount interface. Optional WM-L640V landscape and WM-P640V portrait wall mounts are available, but no stand is offered. The leveler tool shows tilt, while the horizontal sensor and installation warnings help confirm correct alignment. The power input covers AC 100-240V at 50/60Hz, and typical consumption is 147W under IEC 62087 or 375W at full white. SmartRooms Qatar offers a free site survey to check mounting, sun exposure and power before you commit. Request a quote from SmartRooms Qatar that includes the wall mount, power and installation details for your site. Quotations are usually returned within one working day.

Questions about 55XS4P

What is the LG 55XS4P built for?

The LG 55XS4P is a 55-inch window-facing display for screens placed behind glass and facing daylight, such as shopfronts, bank counters and hotel entrances. It has a 1920 x 1080 IPS panel and a typical brightness of 4,000 nits. It suits organisations that want promotions and information to stay visible from the street, for example a retail outlet in West Bay that changes its offers several times a week.

How bright is it compared with an indoor screen?

The 55XS4P is rated at 4,000 nits typical and 3,200 nits minimum, a level chosen for locations where sunlight reaches the screen through glass. Indoor display panels are usually specified for lower brightness, so this model suits a large shopfront or lobby window more than a meeting room. Upgraded Quiet Mode lowers output to 2,500 nits with minimal fan noise when a quieter setting suits the space.

Can it handle Qatar's summer heat behind a window?

Only within its rated range. The 55XS4P is rated for 0 to 40°C without direct sunlight and 0 to 30°C in direct sunlight, with 10 to 80 percent humidity. Summer temperatures in Doha often exceed 45°C outdoors, so a window position needs a ventilated or air-conditioned space and an assessment of sun exposure. Ask the SmartRooms Qatar team to review the exact location during the free site survey before you request a quote.

What inputs and outputs does it have?

The 55XS4P has two HDMI inputs with HDCP 1.4, one DisplayPort input with HDCP 1.3, and a DisplayPort output that passes the input signal onward. It also has an RJ45 LAN port, a USB 2.0 Type A port, RS232C in and out, IR in with IR out sharing the RS232C out port, and an external speaker output rated 10W plus 10W. These ports let a control system, a network connection and a laptop or media source work together.

Can several 55XS4P units form a video wall?

Yes. The specification lists a tile mode of up to 15 by 15 displays, so several units can show one larger image. Bezel widths are listed as 12.0 mm and 9.9 mm, so seam appearance should be reviewed for your layout. For a multi-panel lobby wall in Lusail, define the layout, mounting and cabling when you request the quote so the wall is prepared correctly from the start.

Does it need a separate media player?

No separate media player is needed for basic content. The unit has a quad-core processor that runs several tasks at once, and it runs webOS 6.0 with web-app integration, built-in Wi-Fi and Bluetooth, and 16GB of internal eMMC storage. Local content scheduling, USB Plug and Play and fail over are listed in its software features, so a hotel lobby in The Pearl can update schedules without extra hardware.

How do staff update content across several sites?

The listed software options are SuperSign CMS, SuperSign Control+, SuperSign Cloud and Connected Care. The source describes a web-based content solution that gives access to current and historical data from mobile devices, so a manager can change promotions and monitor the unit in real time. For a retailer with branches in Al Rayyan and Mesaieed, this means central updates without a site visit each time.

What is needed to mount it on a wall?

The head weighs 26.0 kg and the packed unit weighs 31.2 kg, so the wall or frame must be checked before fixing. The mount interface is 600 x 400 VESA. The optional WM-L640V wall mount suits landscape use and the WM-P640V suits portrait use, and no stand is available. The leveler tool shows tilt, and a horizontal sensor with installation warnings helps confirm the correct direction. SmartRooms Qatar offers a free site survey before installation.

Can it run on Qatar's 240V, 50Hz power supply?

Yes. The power input is listed as AC 100-240V at 50/60Hz, which covers Qatar's 240V 50Hz mains, and the power supply is built in. Typical consumption is 147W under IEC 62087 and 375W at full white, with a 400W maximum and 145W in Smart Energy Saving mode at 70 percent. Standby and power-off draw are listed at 0.5W or less. Confirm when you request the quote that the supplied power cord suits the BS 1363 sockets at your site.

Which safety and EMC certifications are listed?

The source lists CB and NRTL for safety, and FCC Class A, CE, KC and VCCI for EMC. ErP is marked as listed, while Energy Star is not. The cradle-to-grave carbon footprint has been verified by the Carbon Trust. If a government tender requires specific documents, ask the SmartRooms Qatar team to confirm them with your quotation before you submit your bid.

What is the difference between the 55XS4P-B and 55XS4P-BP variants?

The manufacturer lists two variants, 55XS4P-B and 55XS4P-BP, but the data provided does not explain the differences between them. This page therefore describes the 55XS4P specification in general. State the variant code you need when requesting a quote, so the quotation matches the unit, accessories and wall mount required for your project.

Can a school or government office buy it through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. Quotations are usually provided within one working day. For a school in Education City fitting out several reception windows, list each location and its mounting orientation in your request, so the quote includes the correct wall mounts and the site survey.
