NUC7PJYH no 4k 10 bit Output

[JSchl14]

Hello,

my NUC7PJYH System won't output 4k 60hz 10 bit.

Latest Windows 10 update and all updates via the driver assistant installed.

I am only getting 8 bit YUV444 60hz@4K / RGB or Ycbcr 420 8 bit.

Am I correct that the system should be able to do Ycbcr 420 10 bit (at 4k 60 hz)?

My understanding so far is that the driver will pair with the display automatically and i can't force 10 bit via settings?

"Monitor" is an 4k HDR10+ capable Hisense H55BE7000 TV, using an HDMI 2.0 (18 Gbit/s) cable.

Any idea what else i can try to get 10 bit / HDR working?

Hello JSchl14

Thank you for posting on the Intel® communities.

Regarding your inquiry, we would like to inform you that right now there is no way to manually set Chroma Subsampling, this happens automatically based on the system and support offered by the TV, e.g. if you set up your graphics properties to 4K@30hz and using HDMI 2.0 and the TV supports it, the Graphics driver will set up the output to 4:4:4, if you raise your configuration to 4K@60hz the system will lower Chroma Subsampling to 4:2:0

The chroma subsampling supported by Intel® is 4:4:4 or 4:2:0.

When outputting at 4K with a 60 Hz refresh rate, the maximum supported bit depth, when using the RGB color model, is 8-bit. When using the YCbCr color space the maximum supported bit depth is still 8-bit (when outputting at 4K with a 60 Hz refresh rate), but it will show as YCbCr444 instead of RGB.

For more information, please refer to Tips for Playing 4K or HDR Content on Intel® NUC, section "Changing the Color Depth/Chroma Subsampling".

Also, High-dynamic-range (HDR) requires a series of system requirements for this technology to be enabled, for instance, the Intel® HDR White Paper lists Intel® HD/UHD Graphics integrated on 7th generation Intel® Core™ Processors or newer as supported for HDR, however, Intel® NUC Kit NUC7PJYH comes with an Intel® Pentium® Silver J5005 Processor. We are double-checking to see if this will be also a limitation for HDR.

Should you have additional inquiries, please let us know.

Note:

A solution is in the works to add the option for manually select Color Depth and Color Space via Intel® Graphics Command Center.

We recommend you to look for future releases of Intel® Grapchis Command Center. We do not have a specific date but we are hoping it is by the Q2'20 (however, dates may shift).

Hello Andrew,

thank you for the detailed answer! Really all the info i was looking for :)

The NUC7PJYH comes with an UHD 605 - hope that will be enough to output the desired resolution and bit depth also its "just" the pentium silver and no core processor.

It would be great to have more advanced control options in the  Graphics Command Center.

So for me i would prefer 10 bit 4:2:0 over 8 bit RGB or 4:4:4. Be i understand why the driver chooses otherwise.

Looking forward to that command center update!

It would be really nice to have the possibility to override settings if the communication between the display and driver does not result in the desired recommendation of settings (maybe a advanced settings toggle?).

Hello JSchl14

Thank you for your response.

We are glad to know the information provided was helpful and we want to thank you for the feedback and recommendations regarding configuration options on Intel® Graphics Command Center. We have shared this feedback with the proper team.

Regarding HDR support, we are still checking this and we will be updating the thread as soon as more details are available. Thank you for your understanding.

Hello JSchl14

We would like to update this thread regarding HDR support.

The Intel® NUC Kit NUC7PJYH (formerly JUNE CANYON) doesn't support 4K@60Hz 10 bit. Per Technical Product Specifications (TPS), Section 1.5.2 High Definition Multimedia Interface, page 20, the maximum supported resolution is 4096x2160@60Hz at 24bpp and the Maximum DDI data rate is 5.94 Gbps.

We would like to provide some clarification:

• 24bpp (bits_per_pixel) = 8bpc (bits_per_channel — red/green/blue)
• 30bpp (bits_per_pixel) = 10bpc (bits_per_channel — red/green/blue)

When talking about 10bit this actually means 10bpc that is equal to 30bpp (or even 32bpp if the additional alpha channel is used). The June Canyon NUC supports only 24bpp at 4K@60Hz.

We can also doublespeak this by using calculator* [https://k.kramerav.com/support/bwcalculator.asp]:

• 4096 * 2160 * 60Hz * 10bpc = 6.37 Gbps >> 5.94 Gbps (not enough bandwidth to support).
• 4096 * 2160 * 60Hz * 8bpc = 5.31 Gbps << 5.94 Gbps (enough bandwidth to support).

We hope that this information clarifies your inquiries. Should you have additional questions, please let us know.

Hey Andrew ,

sorry for my late reply - as you cant fight the bandwidth everything is fine :)

Thank you for the great support and your detailed answers.
