What I read: Gemini Lake on laptops support HDR10 but only on internal laptop displays.

 Where did you read that? Yes it says so in the driver's release notes, but this is a "generic" driver, for all of the recent IGP's, not just for Gemini. And no Gemini specific statements I've could find regarding. So i guess it still applies only to the IGP's that already had HDR support. Regardless I think it's right that it could have HDR support if they wanted to have so...  

Yes, I read this, but I read it a little bit wrong. Maybe I read it too fast or it was too late.

What I read wrong is the restriction to internal displays only!
It seems to be also on external display: "enabling full quality HDR10 ... on both external and laptop displays" (first sentence of the release notes).
Unter "NEW FEATURES" of the release notes it's summarized to "HDR10 in embedded laptop displays" and "HDR and EDR enhancements for external and laptop displays". [I never heared the term EDR (Enhanced Dynamic Range) before.]

It's clear that this is a generic driver (but only for 6th generation and later, including Appollo Lake and Gemini Lake).
Since this is a thread for "Gemini Lake", I only consider Gemini Lake.

If the release notes say that HDR/HDR10 is supported now and if there is no restriction for Gemini Lake, I assume and expect that HDR is also supported by the Gemini Lake chips!
Since I'm not using Windows and I don't have a HDR display, I can not test it.


I know, there are a lot of statements that Gemini Lake is not supporting HDR. I'a afraid that this is still true.
It's also very disturbing, that Intel specified HDR in its J5005-NUC initially.



P.S.: Intel, look at the new Fire TV Stick 4K, which will support HDR, incl. Dolby Vision, at a price of 50 $.
