I have recently purchased a Chromecast Ultra (CCU) to view 4k/HDR connected to my Optoma UHD65, via a 10metre fibre optic HDMI, from my Onkyo TX-SR353. I have the CCU connected via Ethernet.
When I view specific HDR content on Youtube, specifically, the HDR Channel, all the videos appear very oversaturated and discoloured. I am concerned that I am not receiving HDR signals on other content I may view, such as Netflix and so forth.
Here is a link to one of the specific HDR videos:
I have attached a couple screenshots to show the issue.
I am hoping someone may be able to confirm if it is either the videos themselves that are the problem, or if in fact, there is something preventing true HDR from being displayed on my projector.
Thank you in advance,
