That driver is somewhat older then the final version with a lower version-number that is released by Intel on the website. So not really a final one I guess (for Insiders maybe).

We have to wait for Intel to release a new WDDM 2.2 driver on there website (or through Windows Update).

Got a lot flickering with that driver so I uninstalled it, will wait to see the final version.
Once Intel fixes the 3D MVC bug with HDMI 2.0, KabyLake and Apollo lake this will be great.
Still have to wait for Kodi to implement HDR.

If you connect your HTPC directly to your LG TV, do you still get HDR playback with PowerDVD 17? I don't have a receiver, but I don't get HDR playback with PowerDVD 17 when the Beebox-S is connected to my TV (HDMI 2.0 to HDMI 2.0a).

If you are using the trail version of PDVD 17 HDR will not work, also make sure you have Windows 10 Creators update and drivers.
