I am new here. I am looking to purchase an adapter which can plug into my Dell XPS 13 9360 and output 4k HDR Video from a native source file (H.265/HEVC 10 bit) to a 4K HDR capable TV. I have checked around online and came to know about this adapter and another one ‘DisplayPort 1.4 to HDMI 2.0b HDR’. Although the latter one explicitly specifies about HDR, the USB C adapter I am interested in doesn’t? Does this product support 4k HDR as per my needs? Please confirm.

Welcome sriharivn,

For HDR to work in a proper manner the source system, in this case your Del XPS 13 9360 needs to have an output with support for DisplayPort 1.4. 
Your Notebook does have a Thunderbolt  output with DisplayPort Alternate Mode Support, but 1.2 spec, not 1.4.
In fact we do not know of any Notebook at this point in time with DP 1.4 support, which is hwy we did not release USB C to HDMI 2.0b Adapter yet.
So the max we can offer at this stage is USB C to HDMI2.0 (CAC-1504 or CAC-2504) for 3840x2160at 60Hz, but unfortunately no HDR Support.

Intel claims its support for DP 1.2 via their built-in graphics on DDI outputs from HD graphics in CPU, which can be used as DP1.2 outputs or as HDMI 2.0a via LSPCON chip with HDMI 2.0a (HDR) support for 7-, 8-generations CPU.

It’s not problem with DP1.2, it’s problem with PS176 converter Parade Tech. Is there no other solution in silicon for DP1.2-> HDMI 2.0a with HDR?

Yes there is, the CAC-2504 supports HDR, it has the same chip inside as the CAC-1080 and CAC-1180,. We dont sell it as such since we do not knwo of any source system that supports HDR over USB C … but if you say that your system does support it … the CAC-2504 is the Adapter for you 🙂
