Precision 7550 - power from dual monitors
Is it possible to use two seperate monitors with USB-C power delivery to power my Precision 7550 via the two USB-C ports?
I know I can power my laptop from a single monitor at <100 W, but can I use two monitors in parallel to deliver the full power requirement (provided the moitors can deliver enough power together)?
Or would it take power only from one USB-C port?
Thanks

The system can be powered by one USB port at a time -- so, the answer is no: you cannot use two inputs simultaneously.

Thank you.
I know though, it’s possible from a dock such as the WD19DC, which has two USB-C connectors.
But I guess it doesn’t work the same with two separate monitors.

Why is it that it can be powered through both ports from a dock and not from seperate monitors?
