Intel's 11th Gen Rocket Lake (Core i-11000) and 12th Gen Alder Lake (Core i-12000) chips no longer support 4K Ultra HD drives. In question, the abandonment of support for SGX, a DRM-related security technology required for playback of UHD BD discs in addition to HDCP 2.2 and AACS 2.0.
No Ultra HD Blu-Ray support on Intel Rocket Lake or Intel Alder Lake chips
In short, it is impossible for owners of a recent Intel PC computer, therefore equipped with a Rocket Lake or Alder Lake chip, to use their UHD BD player to enjoy a 4K Ultra HD Blu-Ray disc. Namely, while the Intel 7000, 8000, 9000, and 10000 series still support SGX technology, publisher CyberLink, creator of the popular PowerDVD software, says it may be removed in future Intel drivers.
Voice over to Cyberlink
Excerpt from Cyberlink FAQ: “Intel SGX functionality has been removed from 11th Generation (or newer) Intel processors, and SGX support may be removed on new versions of Intel drivers or utility programs (for example, the Intel SGX driver and Intel Management Engine). These changes may cause these platforms to lose support for playing Ultra HD Blu-Ray movie discsâ€.
4K Ultra HD Blu-Ray on PC, playback soon impossible
To explain this new provision, as a reminder, SGX support is required since the Skylake chips (Core i-6000), Intel explains that security researchers have found several vulnerabilities in the system, which justifies its abandonment. Namely, at the same time, SGX is not supported by AMD chips. So, even if playing a 4K Ultra HD movie on a PC is not the solution favored by a Home Cinema enthusiast, we can regret that this decision puts an end, except to owning an "old" Intel computer, to the 4K Ultra HD Blu-Ray sessions on PC.
