I have discovered some intersting

I were trying to figure out why my Dell XPS (9350) was so hot and with high CPU Usage when connected with Dell D-6000.

My actual rig is:
Dell XPS (9350) Qhd version - Windows 10 1709
Dell D-6000 connected by USB-C
Dell S2817Q @ 4k 60Hz via HDMI 2.0

I used to have about 40% of CPU Usage in idle. My temps was about 70~80C in idle. And poor performance while playing videos.

I have tried all the output ports in D-6000, with no difference at all. But I decided to try USB-A insted USB-C. As you may know, Dell's D-6000 is supposed to be hooked by USB-C but it has a huge adapter to work in USB-A 3.0 sockets.

And when connected via USB-A te computer suddenly has dropped temps to 50C and CPU usage to 8~15% in idle.

When oppening Photoshop and working with big images, the performance is quite excelent, never exceeding 70C. And all the bad things are now gone, like that horrible mouse lag.
