every article and review I read about the intel nuc hades with 8th generation processors (kaby lake R if you want to be specific) mention intel had stated the machine would play 4k uhd blu rays. clearly that is not possible, as the AMD graphics dominate HDMI output and they don't have the compatible codecs.
one cannot switch to the intel 630 graphics either (that is the only way to play 4k uhd HDR blu rays on a computer, by outputting video straight from the motherboard using the integrated graphics). the whole issue comes from the embedded copy protections from the content and the fact the HDMI outputs, which are very capable of producing 4K UHD HDR signals, are hooked straight to the AMD card.
so was this a case of blatant false advertising or are we missing something here?
I am hoping to try outputting from a thunderbolt 3 port on the back, using an adapter from thunderbolt to HDMI (HDCP2.2) and with the right cable hoping this takes me straight to the motherboard and lets me circumvent the AMD card, but I am not sure if HDR will be possible. will report back soon.
Hi Leonardo, thanks for the reply.
• Make sure that you have installed all the drivers validated for the Intel® NUC that are available for your model in https://downloadcenter.intel.com/ --> Yes, I downloaded the computer drivers from here and the gfx drivers have been updated. I have version 220.127.116.1109 for intel display and version 25.20.15002.58 for AMD.
• What is the model of the Display and video cable that you have? --> I have a Sony Bravia 49XD8305 (latest firmware) which has 2 4K HDR enabled HDMI ports (ports 2 and 3, port 3 also does ARC). 4K HDMI mode is enabled in the settings and I have successfully played 4K HDR content on this display via amazon fire, ps4 pro, and xbox one s. I have an HDCP compliant cable which I have used successfully with this display (from syncwire) to display 4K HDR content. I am connecting the intel nuc hades canyon via the back HDMI port which is the CEC enabled one, but both HDMI ports are capable of 4K HDR. I have 4K resolution in windows and the HDR slider in windows is turned on. I do not get washed colors in windows SDR content because my TV has a graphics display mode that helps with that.
• What other peripherals do you have on the Intel® NUC? --> just the optical drive (via usb 3 and drive enclosure), an LG WH16NS60 which is capable of reproducing 4K UHD HDR blu ray discs. I have a logitech webcam too.
• What steps have you performed to test the video outcome? --> I have used cyber link's blu ray advisor tool and it keeps complaining the graphics card is not capable of playing this content (it fails the PAVP test). I also try to play the disc direcly on powervdvd 18 ultra and it also complains about the gfx card. I have tried going into the windows display settings and telling windows to force powerdvd to use power saving gfx (intel) but that does not work bc there is no HDMI connection going straight to the intel gfx (read below).
• What software are you using to test/measure the video outcome? --> cyberlink powerdvd 18 ultra. I have enabled the SGX guard in the motherboard and the driver has been installed. I have also installed the HEVC and HEIF codecs from the windows store (and successfully streamed 4K HDR netflix on the edge browser). iGFX are ENABLED in the bios.
the bottomline here is that the computer only uses the AMD gfx, and AMD gfx lack the VP9 and PAVP codecs necessary to reproduce 4K UHD blu ray discs. Display is ok, cable is ok, optical drive is ok, software is ok. The only way to successfully play this content on a computer is by connecting the HDMI cable to an output that is linked directly to intel gfx, not AMD, because intel gfx have the right codecs. This has to be a physical connection because of how the VP9 and PAVP codecs work, unless you guys know of a workaround. the minidisplay ports on the back are useless for this purpose bc they are only 1.2 compliant, not 1.4.
I am attaching the txt file you requested.
Hi Leo, yes, it seems you arrived to the same conclusion I've been discussing in this thread.
My issue with this is that reviews published before the device came out said intel had been telling the community a different story: the device would support 4k uhd blu ray play back. Now it turns out we are all finding out that is not the case, it even took you several posts to understand what I was talking about.
Can intel explain why the false signalling? It is very unfair to the consumer, this is an expensive item and a company like intel cannot afford to be so sloppy and unprofessional, maybe even unethical?
