Triple 4K display support
This docking station expands a single USB-C or Thunderbolt port into three video outputs: two HDMI and one DisplayPort, each capable of 4K resolution at 60 Hz. Windows systems can run dual or triple extended displays for multitasking. On macOS, all external monitors mirror the same content regardless of the selected mode. The host must provide DP 1.4 signal output for full resolution.
Sustained connectivity and charging
The hub delivers up to 100 W of Power Delivery charging to the host laptop while simultaneously driving three 4K displays and attached peripherals. Three USB-A 3.0 ports and one USB-C port operate at 5 Gbps for continuous file transfers or accessory use. A single USB 2.0 port is also available for legacy devices.
Passive thermal design
The unit relies on a fanless aluminium enclosure to dissipate heat during prolonged operation with multiple displays and active charging. No moving parts mean silent performance in quiet environments. Power draw scales with the connected laptop and peripheral load, staying within the 100 W PD budget.

Questions about this item
Does the dock run hot or draw much power when driving three 4K@60Hz monitors all day?
The unit uses a single USB-C uplink with 100W power delivery; it has no fan and relies on its aluminium chassis to dissipate heat during extended multi-monitor use.
Which laptop port must I already have for the Belkin 5550/ to deliver video and 100W charging?
Your laptop needs a USB-C port that supports DisplayPort Alternate Mode and Power Delivery; Thunderbolt 3 or 4 ports also work.
Will the dock's dual HDMI and DisplayPort outputs work with my older monitors that only have DVI or VGA inputs?
You will need active HDMI-to-DVI or DisplayPort-to-VGA adapters; the dock itself provides only HDMI and DisplayPort video outputs.
