Dell XPS 15 (9560) with Dell P2715Q - Poor video output/Graphics card selection
I have a XPS 15 (9560) and using it with a Dell P2715Q 4k monitor running through a d6000 dock.
Monitor is connected to the dock from mDP to DP and the dock via USB-C to the laptop.
The monitors performance didn't seem great and the images weren't very smooth. The issue is more when playing video or running AutoCAD 2018. When checking the video settings through AutoCAD it is always the on board graphics that is being used not the dedicated graphics. Even when I use the nVidia panel to force the program and global settings to the GTX1050 it doesn't seem to want to use it for the external display.
Any help would be greatly appreciated because as far as I was concerned the laptop shouldn't have an issue running the monitor at 4k 60Hz.

For now, remove the dock from the troubleshooting. Test the monitor directly to that computer and other computers.. If those apps look good when not using the dock, we would then have to isolate the issue.
