Question about ASUS SimPro 2

When I purchased the docking station, the comparison showed that the ASUS SimPro 2 Thunderbold
has more and better video connections.
Can run 3 monitors, I use 2.
The notebook can be started from the docking station, the notebook stays closed, but when used for a longer period of time, heat is generated.
The notebook is charged.
With this docking, 1 connection on the notebook is sufficient for all functions.
The docking station provides 120 watts compared to the docking station (UBS C) with 180 watts.
