LS490UCM-UF

What the Dahua LS490UCM-UF is built for

The LS490UCM-UF is a 49-inch video wall display unit from Dahua's Ultra Series, designed to work as one tile in a larger multi-screen wall. Each unit carries a Full HD 1920×1080 panel in a 16:9 format, so a grid of them can show one large picture or several independent feeds. It suits command centres, surveillance rooms, meeting rooms and commercial display areas where screens run for many hours a day.

Panel and image facts that matter on a wall

On a video wall the frame between panels matters as much as the picture itself. This unit has a 2.3 mm bezel on the top and left and 1.2 mm on the bottom and right, giving 3.5 mm bezel-to-bezel. The ADS panel is rated for continuous operation, and the display offers the following:

• Brightness: 500 cd/m² with an anti-glare surface (haze 25%, 3H)
• Contrast: 1200:1 with direct LED backlight
• Viewing angle: 178° horizontal and vertical
• Response time: 8 ms grey-to-grey, with 8-bit colour (16.7 million colours)
• Colour temperature: 10,000K, with factory calibration for uniform colour across units
• Reliability: MTBF rated at 50,000 hours

Connectivity and control for multi-unit walls

Inputs include VGA, DVI-D, two HDMI ports, one DisplayPort, RS232, audio and IR. The DP IN port passes the signal on through DP OUT, so a row of units can be daisy-chained from a single source. The unit accepts up to 4K at 60 Hz via DP IN or HDMI 1, and outputs up to 4K at 30 Hz via DP OUT. Control is available by infrared remote or by RS232 from a computer, and the built-in picture splicing function helps spread one image across the wall.

Where it fits in Qatar

A security operations room in Lusail might install a 3×3 wall of nine units to monitor several camera feeds at once. A meeting space in West Bay could use a single unit as a large screen for dashboards and video calls. A hotel lobby or shopping mall in Doha could use several units for brand content, and the quiet, low-energy design suits public areas where noise and power draw matter.

Planning power, cooling and mounting

The mains input is rated AC100 V to 240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply. Typical draw is 135 W and maximum draw is 155 W, with standby below 0.5 W. The stated operating range is 0 to +40°C with 10% to 80% humidity, non-condensing. Qatar summer temperatures can exceed 45°C, so the unit should sit in an air-conditioned room, and the space should be checked before installation.
