55’’ FHD Video Wall Display Unit (Ultra Narrow Bezel 1.7mm)

Name: 55’’ FHD Video Wall Display Unit (Ultra Narrow Bezel 1.7mm)
Brand: Dahua
SKU: LS550UDM-EF

Stock Code: LS550UDM-EF

A video wall unit that takes the seam down to 1.7 mm

An industrial ADS panel runs 24/7 at 1920×1080. A 1.7 mm panel-to-panel bezel joins the images of neighboring units into what reads as one surface, and factory calibration levels the color tone across the wall.

Key features

2.54mm

Active area to active area

The gap between the images of two neighboring units stays at this width.

25%haze

Anti-glare surface

The matte finish scatters overhead light and keeps the image readable.

50,000hours

Mean time between failures

On a wall that stays on continuously, the panel works to this figure.

600× 400 mm

VESA mount

The standard M6 pattern supports both floor-standing and wall mounting.

200W

Typical power draw

Each unit in the wall works at this figure, and the maximum stays at 210 W.

IN DAILY USE

Modular installationThe modular structure allows several floor and wall layouts.

Control from a PCAn infrared remote and RS232 drive the wall from the operator's computer.

Built-in splicingThe unit splits one image across the wall without an extra controller.
