What this dock is designed to do
The current record accepts Thunderbolt 4, USB4, USB-C DisplayPort Alt Mode. Display and charging behaviour can change depending on the host laptop, operating system and whether the connection is running in a full Thunderbolt/USB4 mode or a reduced USB-C fallback mode.
Important dock note: On non-Thunderbolt hosts the dock does not retain Thunderbolt functionality and display ceilings are lower. Exact topology depends on host bandwidth and DSC.
