Hi, 

I'm having a bit of trouble setting up a Precision 5550 with a Dell WD19 dock and i hope some one can help me out with a couple of questions.

1. I'm trying to connect 2 monitors via the Dock, a (Monitor1) 1440P and a (Monitor2) 1080P. I've tried multiple combinations of connecting the monitors on through the DP and the HDMI in different arrangements but Windows display manager wont let me select 1920x1080 for monitor 2.

I perhaps thought i might need to get a USB C to HDMI Adapter to make it work, but after doing some reading it seems that it should all work. 

2. The current power provided by the dock is not actually enough to supply the laptop with enough power, meaning I have to have the power brick and the dock plugged in simultaneously. The power supplied to the dock is 130w, the power supplied to the laptop is via a 130w supply. 

If I upgrade the supply to the dock to a 180w supply will this be enough to supply the laptop through the dock.

 

Thanks for any help you can provide, I'm new to docs and i got the impression it would just 'work'.

Cheers
