I have a Precision 7510 machine connected to a D6000 docking station which is connected to two Dell U2720Q monitors.

Both monitors are connected to the docking station via DP cables.

While trying to use 3D modelling software, I noticed lines were unusually fuzzy and realised the display wasn't using the NVIDIA GPU but the default Intel HD GPU instead.

There was no way for me to make the switch while the laptop was connected via the dock.

When I connect my laptop to the monitor directly via HDMI, the NVIDIA GPU kicks in and works fine and all my problems are fixed but I can't connect both monitors that way (and nor do I want to). The dock was supposed to rid my desktop from cable clutter!!! Please help.
