Currently, the most comprehensive source of information related to DeUHD is over at Myce in the dedicated DeUHD sub-forum.
Yes, they have all the info there. Sign up and be happy.Currently, the most comprehensive source of information related to DeUHD is over at Myce in the dedicated DeUHD sub-forum.
Does anyone here have an nVidia GT 1030?
The upcoming version of CloneBD will support UHD video with transcoding to HEVC Main 10 (also downconverting to HEVC 8 bit, etc...).
Anyway - if anyone has this GPU, please let me know, that would be valuable input for testing.
Has anyone thought about creating an OP for this thread? Maybe a list of "What's needed" to be able to play UHD? Hardware, software, OS, etc. requirements/recommendations?
That's well known: Basic recommended setup
Z270 based motherboard and CPU
Optical drives: recent UHD drive such as LG WH16NS60 (i think)
Software: PowerDVD 17 > extra requirements for UHD playback check the PDVD page
the OS itself doesn't matter i think
Wrong, if you plan to use a licensed player (such as PowerDVD 17) it is required.
Z170 > won't work cause the CPU in most cases lacks the needed S-Spec level for h265 decoding, That list isnt missing a GPU like nVidia Pascal. Try playing an UHD with your GTX 1080 in PowerDVD 17. Aint going to work cause of Intel SGX, UHD = Intel SGX required for closed circuit decoding = CPU's GPU component for display = Z270 based chipset or higher. Do the research.
Wrong again. https://downloadcenter.intel.com/do...uard-Extensions-Intel-SGX-Driver-for-Windows-
That one goes back to Win 8 and the SDK installer even goes to Win 7
Those are indeed the requirements for PowerDVD 17 itself for UHD playback, that's seperate from the SGX requirements themselves. For decrypted content, SGX is no longer needed but scroll down a little to the section
Graphics Processor (GPU)
Ultra HD Blu-ray: Intel 7th generation (Kaby Lake) Core i processors integrated with Intel HD Graphics 630, Intel Iris™ Graphics 640, when you use a dedicated GPU (like the GTX 1080 in my case) the "sgx" chain is no longer secure due to the GTX not being supported. As such PDVD would downscale UHD to standard 1080p
but hey, nobody's perfect happyguy82, even i learn something new every now and then
It will, but as said, if the monitor isn't hooked up to the on-board display ports (the CPU in this case, it's gpu part), PowerDVD 17 will detect it and downscale to 1080. This it because UHD on PC requires SGX, and SGX requires a "secure channel" from source (the optical drive) all the way to output (display) and every component in between. A dedicated GPU doesn't match that criteria as SGX doesn't support those or it does but the driver (nvidia's or AMD if you fancy themà need to add it to the driver, if that's possible.
Even though the GTX 10xx series have the needed hardware do the h265 decoding, the driver doesn't yet support SGX, and that's the problem. The chain no longer secure = no 4k display but 1080p instead.
Yes I'm aware of this. Thanks. Yeah NVIDIA should add this to their drivers and GPU BIOS. Maybe they'll support it with Volta.

Kaby Lake is supported by Intel (meaning official drivers available for e.g. the GPU) on Windows 10 only.Sorry what I really meant to ask was, why does CyberLink insist 4K UHD playback will only work on a Windows 10 PC? Specifically what technology does Win 10 have but not others? Thanks again.

That page says "Platform Software" and says it supports some server boards. I don't know what it does exactly but the issue here is the GPU for which there is no official driver for Windows 7/8.x.But Ch3vron just shared a URL to the SGX drivers that work on windows 7 and 8 too.
