LG 98UM5J 98-inch UHD Large Screen Signage Display

Overview

The LG 98UM5J is a 98-inch standard signage display for lobbies, retail floors and reception areas where a large, sharp screen must run for long hours. Its 3840 x 2160 IPS panel is rated at 500 nit typical, and it includes built-in 10W + 10W speakers and Wi-Fi. It suits hotels, malls and public offices in Doha and beyond that need a dependable large screen for information and promotions.

What the LG 98UM5J is and where it fits

The LG 98UM5J is a 98-inch standard signage display from the UM5J series, with a black bezel and a 16:9 UHD panel. The data sheet describes it as non-smart and without the webOS platform, so content is normally supplied from an external player connected over HDMI. It is built for organisations that want a large, reliable screen for information, promotions and wayfinding, rather than an interactive board or a video conferencing system.

Picture quality and brightness at 98 inches

The 3840 x 2160 resolution is rated by the manufacturer at four times the definition of Full HD, which keeps text and fine graphics crisp for people standing close to the screen in a lobby. The IPS panel offers 178 degree horizontal and vertical viewing angles, so colours stay consistent for people approaching from the side. Typical brightness is 500 nit, with a 1,200:1 contrast ratio, a 60Hz refresh rate and an 8ms response time. The panel also supports portrait and landscape orientation, with rotation changed manually.

Sound, connections and on-panel control

Three HDMI inputs and two USB 2.0 Type A ports
Built-in 10W + 10W speakers, plus SPDIF and phone jack audio outputs
Built-in Wi-Fi and Bluetooth, with an RJ45 LAN port used for firmware updates only
HDMI-CEC support, so the LG remote can control basic functions of connected HDMI devices
16GB internal memory and seven local keys on the panel

Installation planning: weight, wall and power

The head weighs 78 kg and the packed unit weighs 105 kg, so the wall and mounting bracket should be checked before the display arrives. The wall mount interface is 800 x 400 or 800 x 800 mm, and the monitor measures 2198 x 1253 x 79.5 mm. The data sheet recommends mounting close to the wall, which also gives the space a cleaner look. Power consumption is 500 W typical and 560 W maximum, with heat output of 1706 BTU/hr typical and 1911 BTU/hr maximum, so this load should be included in the room's air conditioning and electrical planning. The input is AC 100-240 V at 50/60 Hz, and a power cord is supplied.

Where it works in Qatar

Typical fits include a hotel lobby in West Bay that needs a large welcome screen, a shopping mall in Lusail with a feature display beside the escalators, and a government reception area in Doha that shows service information in Arabic and English. The on-screen menu offers a long language list that includes Arabic and English, which helps when staff in mixed-language offices need the interface in a specific language.

Operating temperature and site conditions

The operating range is 0 °C to 40 °C with 10% to 80% humidity. Summer temperatures in Qatar often exceed 45 °C, so this model belongs in an air-conditioned indoor space, away from direct sunlight through windows and open entrances. If the proposed site is near a glass facade or an outdoor entrance, confirm the conditions with the SmartRooms Qatar team before requesting a quote.

Questions about 98UM5J

What is the LG 98UM5J designed for?

It is a standard signage display, not an interactive board or a video conferencing screen. Its 98-inch UHD panel with 500 nit typical brightness suits lobbies, retail floors, corridors and reception areas where information or promotions must be readable from a distance. The manufacturer rates it for 16/7 operation hours, so it fits venues that run long daily hours, such as a hotel lobby in West Bay showing the day's event schedule.

Is the LG 98UM5J a smart display, and how does content reach it?

No. The data sheet describes it as non-smart and without the webOS platform, so content is normally sent from an external player over HDMI. The on-screen menu includes Arabic and English among its languages. HDMI-CEC lets the LG remote control basic functions of connected HDMI devices. Please confirm your playback setup with the SmartRooms Qatar team when requesting a quote.

What resolution and panel technology does it use at this size?

The panel is 3840 x 2160 UHD using IPS technology, which the manufacturer describes as four times the definition of Full HD. Viewing angles are 178 degrees horizontally and vertically, the contrast ratio is 1,200:1, and the refresh rate is 60Hz with an 8ms response time. At 98 inches, that means sharp text for staff and visitors standing close to the screen in an entrance hall.

Can the LG 98UM5J be used in portrait orientation?

Yes. The panel supports both portrait and landscape orientation, but the screen rotation is changed manually rather than automatically. Portrait mode suits corridor wayfinding, lift-lobby directories and vertical menu boards in a shopping centre. Decide the mounting orientation and content layout before ordering, since the rotation must be set on site.

How heavy is the display, and does the wall need reinforcing?

The head weighs 78 kg and the packed unit weighs 105 kg, so the wall and bracket should be checked before installation. The wall mount interface is 800 x 400 or 800 x 800 mm. SmartRooms Qatar offers free site surveys, so a team can check the wall and the lift or stair route before delivery, for example at a office tower in Msheireb or a hotel in West Bay.

What are the overall dimensions and bezel width?

The monitor measures 2198 x 1253 x 79.5 mm (W x H x D), and the black bezel is 17 mm on the top, bottom, left and right. The carton measures 2440 x 1468 x 275 mm, which matters for doorways, lift cars and stairwells in older buildings. Measure the delivery route against these figures before confirming the order.

Are the built-in speakers enough for a school entrance or a busy lobby?

The display has built-in 10W + 10W speakers, which suit light announcements and background sound. In a large or noisy lobby you may want an external audio system, connected through the SPDIF or phone jack audio output. For example, a private school in Al Wakrah placing a screen in its entrance corridor could use the built-in speakers for short announcements and add external audio if the space is noisy.

Which ports are available for laptops, players and other devices?

There are three HDMI inputs, two USB 2.0 Type A ports and an RJ45 LAN port, which is for firmware updates only. Audio output is available through one SPDIF port and one phone jack. Built-in Wi-Fi and Bluetooth are included, along with 16GB of internal memory and seven local control keys on the panel.

Can it be installed near an outdoor entrance during Qatar's summer?

No. The operating temperature is 0 °C to 40 °C, with humidity between 10% and 80%. Summer temperatures in Qatar often exceed 45 °C, so the display should be installed in an air-conditioned indoor space, away from direct sun through glass and open entrances. Confirm your site conditions with the SmartRooms Qatar team before the installation is scheduled.

How much power and heat does it produce, and what should facilities plan for?

Typical consumption is 500 W and maximum is 560 W, with heat output of 1706 BTU/hr typical and 1911 BTU/hr maximum. Standby draw is 0.5 W. The input is rated AC 100-240 V at 50/60 Hz, and a power cord is included. Facilities teams at a shopping mall in Doha should add this load to the cooling and circuit calculations for the display wall.

Which certifications does the LG 98UM5J list?

The data sheet lists UL and CB for safety, FCC Class A and CE for EMC, and the NewErP label for energy-related products. Energy Star is listed as not applicable. If your tender or procurement file needs certificate copies, include that request in your quotation request so it is handled with the order.

Can a ministry, authority or public school buy this display on a purchase order?

Yes. SmartRooms Qatar supplies on purchase orders (LPOs) and through government tenders, including Monaqasat. Payment can be made by bank transfer, cheque or purchase order. When requesting a quote, state the number of 98-inch units, the wall type and the installation location, so the quotation matches the department's order.
