I am not seeing the HDR option under display settings,how i get that?

This is getting weird. You don't have WDDM 2.2 driver, but you are still getting HDR output from PowerDVD 17? Since you are routing through a Marantz AVR, can you check whether the colorspace is set to BT.2020 when you play a HDR video?

You get the HDR option only with WDDM 2.2. You need to update your graphics driver. What version do you have now? Is it 22.20.16.4612 (2/16/17)?

There is no final Intel WDDM 2.2 driver at this moment for seventh generation Intel iGP's. I found an Insiders version (I guess) that shows WDDM 2.2 under DXDiag, but that doesn't work as it should on my system (22.20.16.4629).

Can you send the link for that driver (22.20.16.4629)?
