Unfortunately this test became a quite lengthy procedure. At the start of the
installation of 472.12 (just after the decompression was finished), all 3
screens switched off and stayed in this state. After waiting 30 minutes, I shut
down the laptop by shortly pressing the power button. After a reboot (and
disconnecting the docking station), the laptop screen again switched off during
the Windows start procedure. I wasn't able to get any display running anymore
(neither the internal one, nor the displays connected to the docking station,
nor a TV directly on HDMI).

I tried hitting Ctrl+F8 during next reboot in order to enter Windows protected
mode, but I had no success. The only way to get the display running again was
to boot the Windows installation via VirtualBox from Linux. After that I could
uninstall the 472 driver via the Control Panel. After another reboot (without
VirtualBox) the system started with SVGA resolution and I could revert to the
"previous" driver (27.21.14.5241, originally installed by Windows Update) via
the Device Manager.

I repeated the procedure (without the docking station) with the same result:
---> 472.12 is not usable at all on Dell Precision 7510. <---

As a last step I tried 461.92. The installation blocked quite long when
updating the driver, but after that the process finished without any problems.
After rebooting and reconnecting the docking station, all 3 screens are still
working.
