4K UHD Blu-ray Playback on PC Desktop is officially dead in 2021?

The main problem is that no one is making new computers with the SGX security technology built into the CPU and motherboard BIOS. SGX is the only approved hardware based security technogy that is approved by the BDA.

Most likely everyone making 4K BD-ROM computer drives will now cease production, since no need to make a 4K BD-ROM drive if there is no longer any official software to playback the media. Cyberlink is recommending consumer go buy a standalone 4K Ultra HD Blu-ray player. But who knows for some companies 2023 might be the last year that standalone 4K Blu-ray players remain in production including possible 2K Blu-ray players. This is another negative blow to the 4K Blu-ray format with no computer operating system supporting the disc format. But at least for the standard 2K Blu-ray format over 1.4 billion Windows PC’s are supported, including the old Windows Vista and Windows 7 operating system.

Would it still work in PowerDVD 21 and earlier on the machines that had SGX? Pioneer still includes PowerDVD 14 with its drives.

Up to a certain point, it should. The software has to go online in order to support new AACS versions. If you have an older disc, you should be fine, unless Cyberlink is monkeying with the software in other, unnecessary ways. Newer AACS versions? That's a roll of the dice.

If newer discs use newer AACS versions, then how come people with the OPPO machines (released in 2017) are still able to play the latest discs? The final update was back in 2019. In the early days of the format, they were talking about discs that would require online authentication the first time they were played on a given machine, but as far as I can tell, no such disc was ever released.

It depends on if the player keys have been revoked. That has happened to PowerDVD in the past, and it's possible they'll be revoked again in the future, either because they've been compromised or as a preventative measure in case they're currently being used but nobody has noticed.

What is most sad, is that by and large most people simply don't care. It certainly was a convenient option that was taken away.

In order to legally playback a 4K UHD disc on PC, the requirements list now is almost insurmountable:
* Need to be a 6th, 7th, 8th, 9th, or 10th generation Intel CPU *with* onboard GPU (not all Intel models, such as those that end with KF, have this)
* Motherboard needs to have an onboard video output, and you have to use this output when playing back discs (instead of your graphics card, for instance)
* Motherboard needs to support SGX and have a BIOS version where it is able to be enabled (not all do, even in above gens)
* Need to use a version of Windows that is old, out-of-date, and vulnerable to security exploits, that supports SGX and automatic updates disabled
* Need to use a monitor that supports exactly 3840x2160 resolution
* Both monitor input and motherboard video output need to support HDCP 2.2
* Need to use old version of PowerDVD that supports 4K UHD discs
* Need a BDROM drive that supports 4K UHD discs

As you can see, you might as well just forget about it because the laundry list is so long its not even worth it.

I would assume that the vast majority of non-Apple machines sold from 2016 to 2020 had the required computing hardware, such as the onboard GPU. All you would have needed was a UHD Blu-ray-capable disc drive. The only time you wouldn't have had an onboard GPU was if you either chose AMD instead of Intel or used or built a machine with a server-based CPU which not many people needed or wanted.

There was a video on YouTube of someone unboxing one of these disc drives and using it to play the UHD Blu-ray of Predator on a pretty typical higher-end laptop of the time, but it appears to have been taken down.

Problem is even if you technically had the right hardware AFAIK there was never any official 4K UHD disc software made for Mac. For the playback to work it requires the entire chain of both hardware and software I specified in my previous post.

I am of course speaking of 100% legal methods and not ones that involve using grey market decryption software

*sigh* We went over this a million times when you were upset that your MBP couldn't (legally) play 4K Blus. If the spec isn't met, it won't happen. If nobody's willing to pay for the work required to getting a new method licensed, it won't get done. If orgs like NVidia and Apple refuse to play ball and help out, especially when it potentially involved getting deep into security features that may not be documented publicly, it's not gonna happen. The BDA refuses to license solutions that put the keys in "open" memory. Until that changes, legal playback is now officially dead on PCs.

They played a rip or a normal Blu, the latter possibly using DVDGo or whatever that one licensed Mac player is called. That's it.

The computer wasn't an Apple machine. The person played it through PowerDVD.

As long as you have working SGX setup and do not uninstall PowerDVD Ultra 17 through 22 it should work fine in theory for 4K Blu-ray discs. But if new AACS security keys are issued for a new release then most likely you will not be able to play that 4K Blu-ray disc since the company said they are no longer supporting PowerDVD Ultra 22 (and prior versions) with updates for 4K Blu-ray and Blu-ray 3D playback. Starting with PowerDVD 17 Ultra in the year 2017 was the first time 4K Blu-ray discs was supported on Windows PC’s.

If PowerDVD 23 Ultra is released next year then the software will not support 4K Blu-ray discs, but only 2K Blu-ray, DVD, and audio CD’s. If the day every comes when Cyberlink stops supporting 2K Blu-ray discs (standard Blu-ray’s) then I am going to stop buying the software. There is also a possibility that PowerDVD 22 Ultra might be the last physical optical media player for a Windows PC. Will just have to wait and see what happens.
