UHD Blu-ray discs are no longer supported on the latest Intel PC processors.

Intel has removed support for SGX, a DRM-related security mechanism required to play UHD Blu-ray discs, from its 11th and 12th generation chips.

Intel 11th Generation Rocket Lake (Core i-11000) and 12th Generation Alder Lake (Core i-12000) processors no longer support SGX (Software Guard Extensions). SGX, in conjunction with HDCP 2.2 and AACS 2.0, is required for UHD Blu-ray playback on PC. This implies that consumers will not be able to use the latest Intel PCs as 4K HDR Blu-ray players.

CyberLink, the maker of PC application PowerDVD, said the elimination of SGX means its software will no longer support UHD Blu-ray playback. While Intel’s 7000, 8000, 9000, and 10000 series processors continue to support SGX, CyberLink warns that this feature may be discontinued in future Intel driver releases.

“Intel SGX support has been discontinued for 11th generation (or newer) processors, and may be removed from future versions of Intel drivers or utility programs (e.g. Intel SGX driver and firmware and Intel Management Engine).These changes may result in the loss of support for playing Ultra HD Blu-ray movie discs on these devices,” CyberLink said in a Frequently Asked Questions document.

“The elimination of SGX capability, along with its compatibility with the current Windows operating system and drivers, has created a significant hurdle for CyberLink in terms of continuing to offer Ultra HD Blu-ray movie playback in our software. As a result, CyberLink has determined that it is no longer possible to support Ultra HD Blu-ray playback on the latest processors and Windows systems.”

Intel has supported SGX since Skylake (Core i-6000), however, security researchers have discovered several flaws in the technology, which is likely why Intel is discontinuing support. AMD processors do not support SGX, it seems that support for UHD Blu-ray movies on PC has ended.
