LG 55UH7F (Discontinued) · Replacements in Qatar

Name: LG 55UH7F 55-inch 700 nits UHD Signage Display (Discontinued)
Brand: LG
SKU: lg-55uh7f
Availability: Discontinued

Overview

The LG 55UH7F is a 55-inch UHD signage display with a 700 nit typical IPS panel, 3840 x 2160 resolution and IP5X dust protection, suited to indoor lobbies and meeting areas. It runs webOS 4.1 with 8GB storage, offers three HDMI inputs and tilts up to 30 degrees. The manufacturer has discontinued this model, so Qatar organisations seeking a replacement should request a quote for a current equivalent.

What the 55UH7F is built for

The LG 55UH7F is a 55-inch UHD signage display for information screens that run through the working day indoors. Its IPS panel offers 3840 x 2160 resolution and a typical brightness of 700 nits, so content stays readable in lobbies, corridors and reception areas that receive daylight. LG has discontinued this model, so this page is written for organisations that already own it, buyers comparing it with newer options, and anyone searching for a replacement.

The facts that matter for a buying decision

Full UHD panel with 1.07 billion colours and 95% BT709 colour gamut
Contrast ratio 1,100:1 and dynamic contrast 500,000:1
24/7 operation rated for at least 50,000 hours of panel life
Head weight 19.0 kg with a 300 x 300 mm VESA mount interface
Built-in 10W x 2 speakers and a built-in power supply
Three HDMI inputs, DisplayPort in and out, DVI-D in, LAN, RS232C in and out

Where it fits in Qatar

A hotel lobby in West Bay might use a 55-inch panel at the reception desk to show check-in times, local events and directions. A private school in Al Wakrah fitting out a corridor could mount one in portrait orientation for class timetables or wayfinding, since the display detects its orientation at first start-up. A government ministry reception in Msheireb would place one where visitors wait, and the on-screen menu includes Arabic, which helps staff set it up for a bilingual reception.

Heat, dust and power planning

The rated operating temperature is 0 to 40 °C with humidity from 10 to 80 percent. Qatar summers can exceed 45 °C, so this display belongs in an air-conditioned room, not on an open terrace or in a space behind glass that takes direct sun. The IP5X rating confirms dust protection, which matters in the Industrial Area and during dust storms, but it is not a waterproof rating. The built-in power supply accepts 100 to 240 V at 50/60 Hz, typically draws 110 W and at most 160 W, and uses 0.5 W in standby. Ask your electrical contractor to confirm the socket and circuit arrangement before installation.

Mounting and installation planning

The bezel is 9.9 mm on three sides and 14.4 mm at the bottom, and the depth is 39.9 mm with the logo fitted. The head weighs 19.0 kg and 24.2 kg packed, so wall brackets must be rated for that load and fixed into solid structure. The panel tilts up to 30 degrees for high mounting, and the horizontal sensor helps align the angle precisely. An optional stand (ST-653T) is available, and the optional OPS kit (KT-OPSF) fits as a piggyback unit because the display has no built-in OPS. For more than one screen, SmartRooms Qatar offers a free site survey before anything is wall-mounted.

To request a quote for a current equivalent or a compatible replacement, send SmartRooms Qatar your room size, mounting height and number of units. Quotations are usually issued within one working day, and lead times are estimates confirmed with the quotation based on stock.

Questions about 55UH7F

What is the LG 55UH7F used for?

It is a 55-inch UHD signage display for indoor information screens, such as wayfinding in corridors, visitor information at reception and content in lobbies. Its 3840 x 2160 IPS panel and 700 nit typical brightness suit rooms that receive daylight. LG has discontinued the model, so compare its specifications with current alternatives before deciding.

Is the LG 55UH7F still sold by LG?

No. LG has discontinued the 55UH7F, and the source data lists the 55UH7F-B as its variant. SmartRooms Qatar can quote a current equivalent or a compatible replacement, matched to the brightness, resolution and mounting you need. Send your room size, mounting height and number of screens with your request.

Does it run on Qatar's 240 V mains?

Yes. The built-in power supply accepts AC 100-240V at 50/60Hz, which covers Qatar's 240 V supply. Typical power draw is 110W and the maximum is 160W, with 0.5W in standby, so plan circuit loading around those figures. Ask your electrical contractor to confirm the socket and circuit before installation.

Is 700 nits bright enough for a lobby with large windows?

The typical brightness is 700 nits with a 1,100:1 contrast ratio, which suits well-lit indoor spaces. The source data gives no direct-sunlight rating, so do not place it facing an unshaded window in West Bay or Doha without a site check. SmartRooms Qatar can review the position and advise on keeping the screen clear of glare.

Can it cope with Qatar's summer heat?

Its rated operating temperature is 0 to 40 °C, with humidity from 10 to 80 percent. Qatar summers can exceed 45 °C, so install it in an air-conditioned room, not on an open terrace or in a space that takes direct sun through glass. If the room conditions are unclear, confirm them with the SmartRooms Qatar team before ordering.

What connections does it have for laptops and media players?

It offers three HDMI inputs, one DisplayPort input and output, a DVI-D input, audio in and out, and one LAN port. Wi-Fi and Bluetooth are built in, and its webOS platform with 8GB internal storage plays content without an external media player. There is no HDMI output and no touch USB.

Can it be installed in portrait orientation in a corridor?

Yes. The display supports portrait and landscape and detects its orientation during first setup, so you do not need manual rotation. A corridor screen in a Lusail office tower or a school in Al Wakrah can be mounted vertically for floor directories or timetables. Confirm the wall space and bracket before mounting.

What does IP5X mean for dust?

IP5X is a dust-protection rating, indicating that the enclosure is protected against dust ingress. This matters near the Industrial Area or in Mesaieed, and during dust storms across Qatar. The rating does not cover water, so keep the display away from splashes, leaks and outdoor exposure.

Can it be tilted for a high-ceiling mount?

Yes. It supports a tilt of up to 30 degrees face down, which helps viewers below a high mount, and the horizontal sensor shows the tilt angle for precise alignment. This suits a lobby in a shopping centre in Al Rayyan. Measure the mounting height and viewing distance before you order.

Does it work with video conferencing and AV control systems?

It is certified for compatibility with Cisco systems and listed as Crestron Connected for integration with professional AV controls. Wake on LAN and SNMP support remote power and monitoring. This suits a boardroom in Doha that connects to teams abroad, but confirm the control protocol your room system uses before ordering.

What if we already run this model?

You can keep operating existing units. If you need additional screens or a replacement for one that has failed, send SmartRooms Qatar the model, quantity, content type and mounting location. We will quote a compatible option that fits your existing setup, where possible avoiding a redesign of the wall.

How do schools and government bodies buy several units?

Ministries, authorities and schools in Qatar can raise a purchase order (LPO), and SmartRooms Qatar handles government tenders, including Monaqasat. Payment is by bank transfer, cheque or purchase order. A free site survey helps plan positions, heights and wiring for multiple screens, and quotations are usually issued within one working day.
