Brand: Dahua
SKU: LS550UDM-UF

Stock Code: LS550UDM-UF

A 1.7 mm bezel wall unit that takes a 4K source

An industrial ADS panel runs 24/7 at 1920×1080 and leaves a 1.7 mm panel-to-panel bezel. The DP input takes a 4K source directly, and the DP output passes the same signal to the next unit.

2.45mm

Active area to active area

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

1.07billion colors

Wide color depth

10-bit processing prevents banding in gradients.

28%haze

Anti-glare surface

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

600× 400 mm

VESA mount

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

180W

Typical power draw

Each unit in the wall works at this figure, and the maximum stays at 195 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.
