Name: LG 43ML5K 43-inch UHD Standard Signage Display for Hospitals
Brand: LG
SKU: lg-43ml5k
Availability: Discontinued

Overview

The LG 43ML5K is a 43-inch UHD (3840 x 2160) signage display with an IPS panel, 500 nit brightness and 24/7 operation, positioned for hospital and public information use. LG has discontinued this model, so SmartRooms Qatar can quote a current equivalent or compatible replacement. Standout features include webOS 6.0, three HDMI inputs and OPS compatibility. It suits clinics and hospital reception areas in Doha that need wayfinding screens.

What the LG 43ML5K is built for

The LG 43ML5K is a 43-inch standard signage display from the ML5K series, designed for hospitals and public information points. It pairs a 3840 x 2160 IPS panel with built-in webOS software and local content scheduling, so messages, wayfinding maps and video loops can run from the screen itself. LG has discontinued this model. If your organisation needs a screen of this type, SmartRooms Qatar can recommend a current equivalent or compatible replacement.

Image quality and the specifications that matter

The panel is rated at 500 nit typical brightness with a 1,200:1 contrast ratio and a 178 x 178 viewing angle, which keeps content readable for people standing to either side of a corridor. The 8-bit colour with FRC produces 1.07 billion colours, and the BT709 95% colour gamut suits standard video content. Response time is 8 ms grey to grey at a 60Hz refresh rate, and the rated lifetime is at least 50,000 hours.

Native resolution of 3840 x 2160 (UHD)
500 nit typical brightness with 25% surface haze treatment
Rated for 24/7 operation with a 50,000-hour minimum lifetime
Portrait and landscape orientation supported

Connectivity and remote management

The inputs are three HDMI ports, one DisplayPort, one DVI-D, audio in, RS232C in, IR in, an RJ45 LAN port and a USB 2.0 Type A port. Outputs include HDMI out, audio out and RS232C out, so control signals can pass to another screen. Built-in Wi-Fi, SNMP and Wake on LAN support network management, and tile mode can build a video wall up to 15 x 15 screens. The on-screen menu includes Arabic alongside English, which helps mixed-language teams in Doha.

Where it fits in Qatar

In a hospital in Doha, the screen suits an outpatient corridor showing queue numbers and department directions, with content scheduled differently for morning and evening clinics. A private clinic in Al Sadd can use one unit at reception for service information and pre-visit instructions. An office tower in Lusail can mount a portrait-oriented screen beside the lift lobby to display the floor directory. Its 0 °C to 40 °C operating range means each location must stay within that range, so plan for air-conditioned spaces.

Planning the installation

The head weighs 11.2 kg and 11.8 kg with the optional ST-653T stand. It uses a 200 x 200 VESA interface and can be fitted to the optional LSW240B wall bracket. Tilt is available up to 15 degrees face down, and the body is 39.9 mm deep. Typical power draw is 80 W, rising to 120 W at maximum, and the built-in power supply accepts 100-240 V at 50/60 Hz. Ingress protection is rated IP5X, which guards against dust build-up inside the housing, so it is not intended for open-air or unsheltered positions.

SmartRooms Qatar offers a free site survey to check wall loading, sight lines, glare from windows and the ambient temperature at the mounting point before installation. Quotations are usually issued within one working day, and we accept purchase orders (LPOs) and government tenders, including through Monaqasat. To request a quote for this model, send the quantity, the mounting location and whether you need a stand or wall bracket. Our team will recommend a current equivalent or compatible replacement.

Questions about 43ML5K

Is the LG 43ML5K still sold by LG?

No. LG has discontinued the 43ML5K, so it is no longer part of the current range. If your organisation already owns units or needs a similar screen, request a quote and SmartRooms Qatar will recommend a current equivalent or a compatible replacement with a 43-inch UHD panel, similar mounting options and comparable content management software for your site in Qatar.

What is this display used for in Qatar?

It is a standard signage display aimed at hospitals and public information points. In Doha it suits an outpatient corridor that shows queue numbers and department directions, with content changed for morning and evening clinics. Its built-in content scheduling lets facilities teams plan messages in advance without connecting a separate media player to each screen.

Is 500 nit bright enough for a lobby with windows?

The panel is rated 500 nit typical with a 25% surface haze treatment, which suits interiors with controlled daylight. A lobby with large glass facing the sun in West Bay or Lusail may cause glare on the screen, so place it away from direct sun paths. SmartRooms Qatar can check reflections and sight lines during the free site survey before the wall is prepared.

Can the screen run around the clock?

Yes. The manufacturer rates the 43ML5K for 24/7 operation, with a lifetime of at least 50,000 hours and a 60Hz refresh rate. That suits hospitals and clinics that display information from early morning to late evening. Continuous running still depends on a suitable location, because the operating range is 0 °C to 40 °C and humidity must stay between 10% and 80%.

Which inputs and outputs does it have?

It has three HDMI inputs: HDMI1 and HDMI2 support HDCP 2.2 and 1.4, and HDMI3 supports HDCP 1.4. Other inputs are one DisplayPort supporting HDCP 2.2 and 1.3, one DVI-D input supporting HDCP 1.4, audio in, RS232C in, IR in, an RJ45 LAN port and a USB 2.0 Type A port. Outputs are HDMI out, audio out and RS232C out.

Can content and screens be managed remotely?

The screen runs webOS 6.0 with an embedded content management system that supports local scheduling and group management. The data also lists SNMP, Wake on LAN, Network Ready operation and SuperSign CMS compatibility, plus Crestron Connected for third-party control. Your IT team should confirm network access and firewall rules before deployment so that the screens can be reached from your control system.

Can it be mounted in portrait orientation?

Yes. The screen supports both portrait and landscape orientation, which suits a lift lobby in a Lusail office tower showing a floor directory, or a hospital corridor where tall, narrow wayfinding reads more easily. Confirm that the mounting bracket and cable routing allow rotation before fixing the screen to the wall.

Can it be installed outdoors or in an unconditioned area in Qatar?

No. The operating range is 0 °C to 40 °C with 10% to 80% humidity, and it carries an IP5X rating, which protects against dust build-up rather than providing a sealed outdoor enclosure. Outside temperatures in Qatar's summer can exceed 45 °C, so install it only in air-conditioned spaces and confirm the ambient temperature at the mounting point during a site survey.

What mounting options and weights should I plan for?

The head weighs 11.2 kg and 11.8 kg with the optional ST-653T stand. The VESA mount is 200 x 200, and the optional LSW240B wall bracket is available. Tilt is rated up to 15 degrees face down. The body measures 962.5 x 568.0 x 39.9 mm, so plan wall fixings and cable access for a panel of this size, and book a free site survey with SmartRooms Qatar before installation.

What power does it need and how much does it use?

The built-in power supply accepts AC 100-240 V at 50/60 Hz, which includes Qatar's 240 V mains supply. Typical consumption is 80 W and maximum is 120 W. In smart energy saving mode the rating is 56 W, and in power-off or DPM it is 0.5 W. Heat output is listed as 273 BTU/hr typical and 410 BTU/hr maximum, which matters when sizing air conditioning for a small room.

Can several units be used as a video wall?

Yes, tile mode supports up to 15 x 15 screens. The bezel is 8.4 mm on the top, left and right and 14.4 mm at the bottom, so the horizontal seam below each panel is wider than the sides. A bank lobby in Doha building a video wall should plan the grid around that difference and confirm the layout during the site survey.

What comes in the box and which accessories are optional?

The box includes a remote controller with two batteries, a power cord, a quick start guide, a regulation book and a phone-to-RS232C gender adapter. Optional accessories are the ST-653T stand, the LSW240B wall bracket and the KT-OPSF OPS kit, as the screen is OPS compatible. Ask SmartRooms Qatar to quote these together with the display.
