Hi Kiri,
Thanks for the additional information, the cable should support HDMI 2.0 ( which should work well with our adapter ). Unfortunately we do not currently have a DisplayPort to HDMI adapter that supports HDMI 2.0b ( required for HDR10 or 10 bit color ). Some conversion chips do exist to support HDMI 2.0b however we have not yet found a solution that meets our standards. With the ever increasing number of HDR televisions I expect to see more manufacturers moving to HDMI 2.0b converter chips and availability to increase, but there will be some lag behind the market as we await development and testing.
Thank you,
Pat
