A:AnswerHi, there. This model has a 5K Daisy Chain-- The Productive Workstation, Thunderbolt and DisplayPort support Daisy Chain setup so you can connect two monitors and a laptop for enhanced productivity*.
This feature is not compatible with Macbook products that do not support Thunderbolt (2015 - 2017) or all iPad products. ^Vanessa
A:AnswerI only have the monitor plugged into the power mains and my laptop connected using the thunderbolt 4 cable. The laptop receives power from the monitor only. Resolution is set to 5k 2k setting. It works fine.
