Name: LG 75UH5J-M 75-inch UHD Standard Signage Display (Discontinued)
Brand: LG
SKU: lg-75uh5j-m
Availability: Discontinued

Overview

The LG 75UH5J-M is a 75-inch UHD IPS signage display with 10-watt built-in speakers and webOS 6.0. LG has discontinued this model, so buyers in Qatar should request a quote for a current equivalent or compatible replacement. It suits lobbies, meeting rooms and retail floors that run content around the clock, with 24/7 operation rated in its specifications and split-screen layouts for several sources at once.

A 75-inch UHD panel for continuous indoor display

The LG 75UH5J-M is a 75-inch indoor signage display with a 3840 x 2160 native resolution, an IPS panel and an edge backlight. LG has discontinued this model. This page is written for organisations that already own one, for buyers comparing it with newer signage, and for anyone who needs a like-for-like replacement. SmartRooms Qatar can quote a current equivalent or a compatible replacement.

The specifications that matter on a busy screen

Brightness is rated at 500 nit typical, which suits indoor areas with controlled lighting such as meeting rooms, hotel lobbies and retail aisles. The 178-degree horizontal and vertical viewing angles let people standing to the side read the same content. The 28% haze surface treatment helps reduce reflections. The 120 Hz refresh rate, 6 ms response time (G to G) and BT709 95% colour gamut give smooth, accurate motion for video and animation. The panel is rated for 24/7 operation, and LG lists a lifetime of 50,000 hours for regular use.

Connectivity and control for several sources

Three HDMI inputs per unit, plus DisplayPort, DVI-D and audio inputs
DisplayPort and HDMI daisy-chain input with HDMI output to pass the signal to the next screen
RS232C serial input and output, an IR input and one RJ45 LAN port for network control
One USB 2.0 Type A port, built-in Wi-Fi and Bluetooth, and 16 GB of internal eMMC storage

The software runs on webOS 6.0. Operators can schedule local content, manage groups of screens, use picture-in-picture and up to four pictures side by side, and play video from a URL. The panel supports Crestron Connected for integration with professional AV controls and carries Cisco certification. It is compatible with SuperSign CMS, SuperSign Control+, SuperSign Cloud and Mobile CMS. The on-screen menu is available in Arabic and English among other languages.

Where it fits in Qatar

A hotel lobby in West Bay showing arrivals information and promotions, where the 75-inch size reads clearly from the reception desk.
A government office in Msheireb with a visitor waiting area, where bilingual service information can be scheduled to run during working hours and switched off after closing.
A training room at a private school in Al Wakrah or a training centre in Education City, where the panel serves as a shared display with two built-in 10-watt speakers for short audio clips.

What to plan before ordering

The head weighs 41.5 kg and ships at 51.2 kg, and the monitor measures 1682.4 x 960.3 x 57.9 mm without handle and logo. The VESA mount interface is 600 x 400 mm. The optional LSW640A/B wall mount is listed by LG as an accessory. Power is 100-240 V AC at 50/60 Hz with a built-in power supply, drawing a typical 170 W and a maximum of 230 W. Operating temperature is 0 to 40 °C with 10 to 80% humidity, so confirm the installation environment before mounting it near windows, entrances or any area that is not air-conditioned. An OPS kit (KT-OPSF) is optional, and OPS power is not built in.

Because of the weight and the wall structure needed, a free site survey is recommended before installation. Our team can check the wall, cable routes and power point first.

Questions about 75UH5J-M

Is the LG 75UH5J-M still available from LG?

No. LG has discontinued the 75UH5J-M, so new units are not part of its current range. SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches your existing layout, mounting and connectivity needs. Share the quantity, the location and whether you need to keep the same HDMI and network setup, and we will confirm options with your quotation.

What is this 75-inch display designed for?

It is an indoor standard signage display for showing marketing, information and video content. LG positions it for meeting rooms, airports, retail outlets and shopping malls. Its 500 nit typical brightness, UHD resolution and 178-degree viewing angles suit lobbies, corridors and waiting areas where people view the screen from different positions.

What resolution and brightness does the panel offer?

The panel has a 3840 x 2160 native resolution (UHD) on a 16:9 IPS panel. Brightness is 500 nit typical, and the contrast ratio is listed as 1,100:1. The 28% haze surface treatment reduces reflections, and the screen can be used in portrait or landscape orientation, which helps with menu boards and vertical signage.

Can I use it in an outdoor or very hot area in Qatar?

The operating temperature range is 0 to 40 °C, with 10 to 80% humidity. Qatar summers regularly exceed 45 °C, so this model should be installed in an air-conditioned indoor space. Do not place it near outdoor entrances, open sunlit windows or areas exposed to dust storms without confirming the environment with the SmartRooms Qatar team first.

Which video inputs and ports does it have?

Each unit has three HDMI inputs, one DisplayPort input, one DVI-D input, an audio input, RS232C serial input and output, an IR input, one RJ45 LAN port and one USB 2.0 Type A port. It also has an HDMI output. Touch USB and a separate DisplayPort output are not listed, so confirm your source devices before ordering.

Can several screens be daisy-chained from one source?

Yes. The source data lists DisplayPort and HDMI as daisy-chain inputs, with HDMI as the output. This allows the signal from one display to pass to the next screen in a video wall or multi-screen row. For a wall of several panels, the cable routing, source capacity and resolution settings should be planned with the quotation.

Does it support an OPS computer slot?

Yes, it is listed as compatible with OPS in a piggyback arrangement. The optional OPS kit (KT-OPSF) is sold separately, and the OPS power is not built in, so the slot relies on the display for mounting but not for power. This is useful for a lobby or boardroom where a media player or computer must sit behind the screen.

How is content managed across several screens?

The webOS 6.0 platform offers local content scheduling, group management, USB plug and play, fail over, screen rotation and Wake on LAN. It supports SuperSign CMS, SuperSign Control+, SuperSign Cloud and Mobile CMS. Operators can run the same playlist on a group of screens, or schedule different content for each location from a central system.

How much space and weight must the wall or mount support?

The monitor measures 1682.4 x 960.3 x 57.9 mm without the handle and logo, the VESA interface is 600 x 400 mm, and the head weighs 41.5 kg, or 51.2 kg packed. Because of this weight, the wall structure, mount rating and access must be checked before installation. A free site survey from SmartRooms Qatar helps confirm these details before the panel is delivered.

What is the power draw, and will it work on Qatar mains supply?

The power supply accepts 100-240 V AC at 50/60 Hz, which covers the 240 V, 50 Hz supply used in Qatar. Typical consumption is 170 W and maximum is 230 W, equal to 581 BTU/hr typical. The source lists 120 W under its smart energy saving setting. Use these figures when planning the power circuit and cooling load for a meeting room or lobby.

Can a school or university buy several units through an LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, and can quote several units for classrooms, lecture spaces or a campus lobby. Each unit includes a remote with two batteries, a power cord and a quick start guide. Send the number of panels and locations, and the quotation will list the accessories and optional OPS kit or wall mount you need.

What is included with the display, and what is optional?

The basic package includes a remote controller with two batteries, a power cord, a quick start guide, a regulation booklet and a phone-to-RS232C adapter. The OPS kit (KT-OPSF) and LSW640A/B wall mount are optional. The manufacturer's warranty applies to the product, and SmartRooms Qatar will confirm the exact accessories in your quotation.

Which certifications does it carry for safety and emissions?

The source data lists CB and NRTL for safety, FCC Class A, CE and KC for EMC, and ERP (NewErP) and Energy Star compliance. The IP5x dust-proof certification is cited in the manufacturer's feature description. Ask for the certificates if your tender or site audit needs them, and SmartRooms Qatar will provide what is available with your quotation.
