Triple Display Docking Station

The ALOGIC DUCMA3 is a USB-C docking station built for professionals who need to extend or mirror their Windows laptop across three external monitors at up to 4K resolution. It delivers a single-cable workspace that adds displays, peripherals and wired networking while charging the host device.

Users needing three 4K displays and laptop charging

This dock suits Windows laptop owners who require simultaneous triple-display output, gigabit ethernet, an SD card slot, a 3.5 mm combo audio jack and multiple USB-A ports alongside 100 W power delivery. It does not suit buyers whose laptop lacks a USB-C port that supports video output and power delivery together, or those who need more than three video outputs.

100 W USB-C Power Delivery

The dock provides up to 100 W of charging power to the connected laptop over the same USB-C link that carries video and data, removing the need for a separate power brick. Confirm that your laptop accepts 100 W charging via its USB-C port before purchase.

Questions about this item

What ports on the ALOGIC DUCMA3 might wear out from daily plugging and unplugging?

The USB 3.1 Gen 2 USB-C, USB 3.1 Gen 1 USB-A, USB 2.0 USB-A, Gigabit Ethernet, 3.5 mm combo jack and SD card slot see the most physical cycles; the dock itself has no user-replaceable parts.

Which connection caps throughput when all three 4K displays plus Ethernet and USB 10 Gbps devices run together?

The single USB-C upstream link carries video, 10 Gbps USB 3.1 Gen 2 data and 100 W charging simultaneously, so that shared bandwidth is the first bottleneck.

How much heat or fan noise appears when the dock delivers 100 W charging and drives three 4K screens all day?

The unit is passively cooled with no fan; sustained 100 W delivery and triple 4K output warm the aluminium enclosure but produce no audible noise.
