USB 3.1 Type C to HDMI 2.0 UHD Active Adapter – HDR Support?

Hi,

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.

 

Thanks.

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 🙂

I just ordered the CAC-2504 to see if it will work. The newer Intel Thunderbolt 3 chips will support DisplayPort 1.4 over USB-C. Have you done any testing with these? Do you have any adapters planned using the new Parade PS186?

looking forward to your feedback.
I am sure that PS186 will be extensively tested if that did not happen already …

Hi
Did you have any luck with the test? I am looking for the same solution: I have a Lenovo X1 Yoga 3rd generation with HDMI 1.4. It is not clear in any of their specs if it supports HDR over the USB-C port. Just that the highest resolution is achieved over USB-C.

From all the research I did, including the Intel HDR whitepaper, it should work with CAC-2504

Thank you

@,
Yes, I got it to work. I used a Lenovo X1 Yoga 3rd generation connected to a LG OLEDE7P on Windows 10 1803.  I can enable HDR and WCCG at 4K[email protected] over TB3. I am not positive of the bit depth nor encoding.  The Settings panel says it is 8-bit dithered RGB. I made the change to YCbCr in the Intel control panel and it doesn’t change what is stated in the Settings panel.  My display supports 12-bit HDMI deep color. It supports 4k60p with 4:4:4. Enabling and disabling 4:4:4 on the TV didn’t effect what is stated in the Settings panel. Youtube and Netflix shows HDR.  This setting for this is the Stream HDR video. I didn’t spend a whole lot of time with figuring out the bit depth since my TV doesn’t display the actual bit depth info. It does display the color space and resolution which it stated at 2160 and BT.2020.

Actually I want to correct the above post that Netflix shows 4K and not HDR.  HDR doesn’t seem to work correctly. Since it can show 4K, I am assuming HDCP 2.2 works correctly. It might be that HDR does not work from it trying to show Dolby Vision on my TV since the Lenovo X1 Yoga Gen 3 supporting DV on the internal display.

Thank you for the info
I have the same laptop so this means it will work for me. As you can see in my posts below I also reached the same conclusion as you did and ordered 🙂

So what I understand from you is that Netflix identifies the laptop monitor first and so it shows Dolby Vision instead of HDR. There is Netflix content that is HDR, so I suggest that you show your screen only on TV (not duplicate or extended) and then open Netflix. It should detect properly.
I will be using this setup for private content anyway, not Netflix, because the TV does a good job at playing Netflix directly.

Can’t wait to get mine now 🙂

@MST1407, you can advertise it properly now 😉 it works if Intel conditions in the HDR whitepaper are met

thanks for the feedback 🙂

Hi MST1407,

After researching a bit, I see that the chips supporting DP to HDMI 2.0b (I am interested in 4K HDR) are the Parade PS186 and MegaChips MCDP2900. Can you please tell me if any of your adapters have these chips?

Thanks

CAC-1080, CAC-1180 and CAC2504 all have MCDP2900
For CAC-2504 we jsut did not communicate that because to our knowledge there were no source systems yet that could do 4K 60Hz HDR over USB C or TB2/3. If i am not mistaking that Intel Ridge Chip with supprot for that will come Q4 into the market …

Thank you
FIY, if you google search 4k hdr usb-c hdmi you find CAC-1584 as PDF. After that you can’t find it anywhere else 🙂

From all the info I got from ark intel and other sources, Kaby Lake (7th generation) and forward supports 4K 60Hz 24bpc, so also HDR. My Lenovo’s Yoga 3rd gen specs also states that is supports higher than 4K reseolution 60Hz on Thunderbolt. Adding the requirements in the Intel HDR Whitepaper, that I all meet (version numbers of MEI and SGX) I believe that it will work 🙂

So I ordered CAC-2504 and it should work, if the MCDP2900 specs are right.
I will keep you posted (in two weeks time, aprox)

on 11-09-2018

CAC-1584 was what we initially intended to call what is now the CAC-2504. Most probably in  Q4 2018 we will actually start shipping this product as CAC-1584. In fact they are the same.
Looking forward to your feedback.
