98UM3F

What the LG 98UM3F is built for

The LG 98UM3F is a 98-inch ultra high definition display from the UM3F signage series, designed for indoor spaces where a large, sharp screen must hold attention in a boardroom, reception area or communal hall. Its 3,840 x 2,160 IPS panel carries four times the pixels of Full HD, and a 178 x 178 viewing angle keeps colour and detail readable for people standing well off-centre. LG has discontinued this model. This page is written for organisations that already run it, for buyers comparing it with newer displays, and for anyone looking for a replacement.

Picture, motion and durability figures

• Brightness: 350 cd/m² typical, best suited to rooms with controlled daylight.
• Motion: 120 Hz refresh rate with 8 ms grey-to-grey response time.
• Contrast and surface: 1,300:1 typical contrast with a 1% haze surface treatment to reduce reflections.
• Panel life: 50,000 hours typical, with a rating for 24-hour operation.
• Video coding: HEVC support, which the manufacturer says halves network traffic compared with H.264.

Portrait and landscape orientation are both supported, so the same screen can run vertical menu content or wide presentation content.

Connectivity and room control

The display provides three HDMI inputs, one DisplayPort input, DVI-D, an audio input and two USB 2.0 ports, plus a DisplayPort output and audio output options. For control, it offers RS232C in and out on a 4-pin phone jack, an RJ45 LAN port and an IR input. Picture-by-picture mode shows up to four input sources on one screen, while picture-in-picture plays a main and a sub picture together. The manufacturer states Crestron Connected certification and Cisco compatibility for meeting-room integration. Control Manager, its embedded web monitoring tool, lets administrators check and control several units in different locations in real time.

Where it fits in Qatar

Three realistic situations show where this size works:

• A government authority in West Bay fitting out a large boardroom where teams in Doha join video calls with colleagues abroad, using the input switching and room control options.
• A multi-campus private school installing a 98-inch display in an assembly hall or lecture space, where a sharp screen must be readable from the back of the room.
• A hotel in Lusail placing a signage screen in an air-conditioned lobby, as long as the space stays inside the 0°C to 40°C operating range.

What to plan before ordering

At 81.1 kg for the head and 119 kg packed, this display needs a planned lifting team and a wall or stand rated for the load. The VESA mount interface is 800 x 400 mm, and the monitor measures 2,191.8 x 1,246.8 x 83.8 mm without handle and logo. The carton measures 2,354 x 1,386 x 420 mm, so check door widths and lift dimensions along the route. The built-in power supply accepts 100-240 V, 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 315 W and maximum 415 W, with a smart energy saving figure of 221 W. Basic accessories include a remote controller, power cord, quick start guide, IR/light sensor receiver, 1.8 m DP cable, regulation book, phone-to-RS232C adapter and an eye-bolt. The unit is not OPS compatible and is listed with SuperSign CMS and SuperSign Control/Control+ software. Listed certifications include CB/NRTL safety, FCC Class A, CE and KC.
