LG 55XF3C (Discontinued) · Replacements in Qatar

Name: LG 55XF3C 55-inch 3,000 nits Open-Frame High Brightness Display
Brand: LG
SKU: lg-55xf3c
Availability: Discontinued

Overview

The LG 55XF3C is a 55-inch class Full HD open-frame display built for bright, hot locations such as shopfronts and lobbies facing large windows. Its panel is rated 3,000 cd/m² typical, with an IPS panel for wide viewing angles and a film layer that keeps the image visible through polarised sunglasses. LG has discontinued this model, so SmartRooms Qatar can quote a current equivalent or a compatible replacement for your site.

What the LG 55XF3C is built to do

The LG 55XF3C is an open-frame digital signage display, which means it is supplied as a bare screen head without an enclosure, so it can be fitted into a custom housing or a purpose-built frame. The panel measures 54.64 inches diagonally within a 55-inch class, runs at 1,920 x 1,080 Full HD resolution and has a typical brightness of 3,000 cd/m², with a minimum of 2,400 cd/m². That brightness keeps content readable on a screen placed in front of daylight.

Visibility features that matter behind glass

The panel uses IPS technology, which gives wide viewing angles and more accurate colour. An embedded film-type patterned retarder with a quarter wave plate keeps the picture clear when viewers wear polarised sunglasses, a practical detail for pedestrians and drivers outside a shopfront in Doha. A conformal coating on the circuit board guards against dust, humidity and other harsh conditions.

Temperature, sunlight and dust limits to plan around

The operating range is 0°C to 50°C without direct sunlight and 0°C to 40°C where the screen takes direct sunlight. The relative humidity rating is 10% to 80%. Qatar summers regularly exceed 45°C, so a unit facing a sun-exposed window needs shade, a ventilated housing or an airflow check before installation. Confirm the enclosure and cooling plan with the SmartRooms Qatar team during the free site survey rather than assuming the rating covers your location.

Power, control and remote alerts

Typical power draw of 230 W and 310 W maximum, with a smart energy saving figure of 100 W.
An auto-brightness sensor and a preset time scheduler reduce power when conditions allow.
RS232C in and out, plus RJ45, for external control.
Email alerts through SNMP when an alarm occurs, using SuperSign C or SI software.
Log file back-up that helps pinpoint when a fault occurred.

Where it fits in Qatar

A retail unit on a West Bay street can run promotions on a 55-inch screen set in the window, where the 3,000 cd/m² typical brightness keeps menus legible in daylight. A bank branch in Al Sadd could use two units at the entrance to show service and queue information. A logistics or industrial office in Mesaieed or the Industrial Area can use remote alerts to report faults without a site visit each time.

What to plan before you order

The head measures 1,235.4 x 709.4 x 106 mm (W x H x D) and weighs 27.0 kg, so plan the wall or frame, the cable route and technician access early. The manufacturer lists no stand for this model, so confirm the mounting method before ordering. Inputs include two HDMI ports, DisplayPort, DVI-D, USB and audio, and the power input covers 100 to 240 V at 50 or 60 Hz. SmartRooms Qatar offers free site surveys, and quotations are usually issued within one working day. Government buyers can order through a purchase order (LPO) or a government tender, including Monaqasat.

Questions about 55XF3C

Is the LG 55XF3C still available from LG?

No. LG has discontinued this model. SmartRooms Qatar can quote a current equivalent or a compatible replacement matched to your brightness, sun exposure and connection needs. Send the model number and a description of the location, and our team will respond with a quotation, usually within one working day.

Who should choose the 55XF3C instead of a standard indoor display?

It suits organisations where daylight reaches the screen, such as a shopfront, a bank entrance with glazed walls or a waiting area beside a window. The 3,000 cd/m² typical brightness is the reason to choose it. In a meeting room or classroom away from window light, a standard indoor display is usually a better match. Discuss the lighting with our team during a site survey.

Can the 55XF3C run in direct sunlight in Doha?

Yes, within limits. The manufacturer rates operation from 0°C to 40°C where the screen receives direct sunlight, and 0°C to 50°C without it. Doha summers regularly exceed 45°C, so a unit in a sun-facing window needs shade, a ventilated housing or an airflow check. Confirm your protection plan during the free site survey before installation.

Will the picture stay readable through polarised sunglasses?

The panel includes an embedded film-type patterned retarder with a quarter wave plate, which the manufacturer says keeps the image visible when viewers wear polarised sunglasses. This matters for a shopfront on a busy road in Al Wakrah, where drivers and pedestrians may wear sunglasses. Test the viewing angle and position on site, because glare changes with the position of the sun.

How does the brightness compare with earlier LG models?

The manufacturer states that brightness was increased to 3,000 cd/m² compared with previous models. The minimum specification is 2,400 cd/m², and 3,000 cd/m² is the typical value. When comparing displays, read these two figures as a range rather than a single number, since they describe expected performance and not a guarantee for your exact lighting conditions.

What inputs and ports does the display provide?

Inputs are two HDMI ports, DisplayPort, DVI-D, audio, USB, an IR receiver and a pixel sensor. Outputs are DisplayPort and external speaker outputs for left and right channels. For control, the unit has RS232C in and out and an RJ45 connection. Check that your media player's output matches one of these inputs before ordering, and tell us if you need a specific cable.

How can the display be monitored remotely?

When an alarm occurs, the 55XF3C can send an email notification through SNMP, using SuperSign C or SI software. The manufacturer also describes real-time remote care and log file back-up, which help identify when a display failed. For an organisation running several screens across branches, this reduces the number of site visits needed to check a fault. Confirm the monitoring setup with us before purchase.

Which signage software does it work with?

The source data lists compatibility with SuperSign-c and SuperSign-w lite, and it names webOS 1.0 as the platform. SuperSign C or SI software is referenced for alarm notifications. If your content management system is different, tell us before ordering so we can check compatibility. Do not assume a third-party platform will work without that check.

How much power does it use, and does it suit Qatar's mains supply?

Typical consumption is 230 W and maximum is 310 W, with a smart energy saving figure of 100 W. The power input is 100 to 240 V at 50 or 60 Hz, which covers the 240 V, 50 Hz supply used in Qatar. Before ordering, confirm that the supplied power cord fits the BS 1363 sockets at your installation point. The auto-brightness sensor and scheduler also help reduce consumption.

What size and weight should I plan for when mounting it?

The head measures 1,235.4 x 709.4 x 106 mm (W x H x D) and weighs 27.0 kg. The manufacturer lists no stand for this model, so plan a wall or frame fixing and check that it can carry the weight. A free site survey lets our team check the wall, the cable route and access for installation before you order.

What comes in the box?

The basic accessories are a remote controller with two batteries, a power cord, an IR extension cable or PCB, an HDMI cable and the manual. The manufacturer also lists optional accessories, KT-SP0 and AN-WF500, but check their compatibility with this model before ordering. Quotations for the display and any accessories are usually issued within one working day.

Can a government body or school order this through a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. If a school or ministry needs several units for windows at different sites, send the list of locations with your request so the quotation covers each one.
