30452: dGPU is hotter/clock is higher since I upgraded to Windows 10 19H1 v1903

See my attached Screenshots for results:

"zweiMonitoreAnDock" = two monitors via dockingstation Lenovo Hybrid-C
"einMonitorAnDock" = one monitor via dockingstations
"einMonitorAnNotebook" = one monitor directly plugged into my lenovo E490

All I do is playing a fullHD youtube video. I waited for five minutes after each switch so that temperature could settle.

Two monitors: ~67°
One monitor via dockingstation: ~65°
One monitor directly plugged into notebook: ~55°

Is this the way it's supposed to work?

So, got myself another Lenovo dock, this time the USB-C dock, for testing purposes. It only allows 2 x FullHD via VGA and displayport, but for testing that's fine.

Result: It works like a charme. While running the exact same programs as with the Hybrid-C docking station, temperature is around 50° instead of over 60°.

So, displaylink people: Why does a brand new Hybrid-C lenovo with each and every driver up to date heat up my CPU by over 10° compared to a lower-end USB-C lenovo dock?

Why is it the users who have to keep testing and do the job you guys should do?
