Nuc12 Confusion HDMI

Hi,

I am interested in the nuc12 especially this NUC12WSKi3. The page https://www.intel.com/content/www/us/en/products/sku/121613/intel-nuc-12-pro-kit-nuc12wski3/specific... and https://www.intel.com /content/www/us/en/products/sku/226257/intel-core-i31220p-processor-12m-cache-... clearly states that the HDMI port is 2.1 but according to the technical documentation https://www.intel.com/content/dam/support/us/en/documents/intel-nuc/NUC12WS-TechProdSpec.pdf page 14 and 18 states that the HDMI ports are 2.0b. So my question is what HDMI version is it?

 

This mini pc from Gigabyte https://www.gigabyte.com/nl/Mini-PcBarebone/GB-BEi3-1220-rev-10#kf which has the same CPU state that it also has HDMI 2.1 and 8K not sure if some can comfirm that this realy is HDMI 2.1.

After doing some more research my gut says it's HDMI 2.0b. The product page of the CPU states HDMI 2.1 but with a resolution of 4096 x 2304 @ 60Hz. The same resolution is listed on page 22 of the Technical Product Specification.

The Gigabyte mini PC with the same CPU states that 1 HDMI 2.1 is 8K and the other is HDMI 2.0a and 4K.
I'm no expert but HDMI 2.1 should be 8K and then the nuc12 would not be HDMI 2.1.

Hope someone can confirm this.

Looks like the WS NUC12 IS HDMI 2.1. Only thing missing is FRL (Full Rate Link) support. This means NO 8k support on HDMI, only 4k60Hz.

If you need anything larger than 4k60, you must use the Type-C/Thunderbolt port with an HDMI dongle. And you can only use (1) 8k display this way. You can still have a 4k display on the HDMI port as well.

 

Found this on an HDMI site.

 When HDMI 2.1 Isn't HDMI 2.1 - The Confusing World of the Standard, "Fake HDMI 2.1" and Likely Futur...:

 

  1. HDMI 2.0 no longer exists, and devices should not claim compliance to v2.0 as it is not referenced any more
  2. The features of HDMI 2.0 are now a sub-set of 2.1
  3. All the new capabilities and features associated with HDMI 2.1 are optional (this includes FRL, the higher bandwidths, VRR, ALLM and everything else).

So, technically it IS HDMI 2.1 just not the full spec release, which most venders do not support either in such a small formfactor.

Hello Pepreal,


Thank you for posting on the Intel® communities.


As you very well deducted, the version of the HDMI ports on the Intel® NUC 12 Pro Kit NUC12WSKi3 are version 2.0b. The NUC itself actually has an HDMI 2.0 bandwidth specifications, and the maximum data rate is 14.40 Gbit/s.


This is due to a recent name change of HDMI by the authorized organization, HDMI Licensing Administrator. HDMI 2.0 can now also be called HDMI 2.1.


The Technical Product Specifications document shows HDMI 2.0b (old), but the Ark page shows HDMI 2.1 TMDS Compatible (new).


Please let me know if you have any concerns.


Best regards,

Thanks for confirming, then it seems to me that the gigabyte is really HDMI 2.1 with a data rate of 42.0Gbit/s. According to the specifications of one of the two HDMI port you can achieve a resolution of 7680 x 4320@60Hz probably with DSC. As far as I can find this is not possible with HDMI 2.0b. Is this correct?

Correct, the maximum resolution you can reach through HDMI in this NUC is 4096x2304 at 60Hz.


In regard to the Gigabyte device, I recommend you to contact Gigabyte Support for more information/assistance.
