XPS 8950, 4K support requires Intel SGX enabled in BIOS
I have a Dell XPS 8950 Desktop and need to enable Intel SGX (Software Guard Extensions) in the BIOS (Set to Software Controlled). Does anyone know how to do this? Is it not needed with Windows 11. I have an Intel i9-12900 CPU. I am trying to play 4K disk using a drive capable of playing 4K.
Any help is appreciated.

@RoccoP326 I found this through a Google search. You should read this article: https://www.intel.com/content/www/us/en/support/articles/000058952/software/intel-security-products.html
The article says you should enable Intel SGX in the BIOS, see page 66 of the Service Manual, Then you need to download and install the Intel Software Guard Extensions App.

I think they changed/upgraded the copy-protection on those. So, remember your "Player App" has to support these latest optical discs. If not, you will run into HDCP errors.
It would be easier to just buy a capable stand-alone player. Connect it to your small computer monitor if you want to.

The good news is I had a drive that will work. I just need to figure out how to make the change to the BIOS. I’m beginning to think that Dell did not include this in the BIOS and it will be missing until they come up with a BIOS update.

@RoccoP326 Is the setting for Intel SGX Enable on page 66 of the Service Manual missing in the BIOS?

Vic,
Page 66 of the XPS 8950 talks about setting a password. Are you talking about a different Service Manual or another page?

Re: I found the SGX in the XPS 8950 Service Manual on page 64. I went into the BIOS and the SGX section is not there.
Dell should reinstall the BIOS for you or reflash it to the correct version. I think they have somehow dropped it from paper spec to real .exe

Vic thank you for looking in the service Manual but it appears that SGX is not in the BIOS delivered for the XPX 8950.

I’ll try Tech support again on Monday if no one from Dell responds sooner. There weekday support may be different then the weekend team which I have had no luck with.

@RoccoP326 I am sorry, but it appears I was looking at the Service Manual for the XPS 8940. I see it in the Service Manual for the XPS 8950. Did you check all the tabs and sub-menus in the BIOS? Were you able to see the other menu items listed under the Intel Software Extensions menu? It seems strange to me that the Service Manual describes Performance, Power Management, and Post Behavior are under the Intel Software Extensions menu.

I looked in the BIOS on my XPS8950 and checked all the tabs and menus, I didn't see it. I am running BIOS version 1.0.8

12th Gen Intel CPUs no longer support Intel Software Guard Extensions (SGX). So this must be a bug in the XPS 8950 Service Manual.
EDIT: I pinged my Dell tech contacts...

BTW: You never mentioned if you're using onboard Intel UHD Graphics or an add-in video card (which one?).
If you're trying to use Intel UHD Graphics to play 4K Blu-Ray, Intel removed whatever is required for the DRM to enable native PC 4K UHD Blu-ray hardware playback.
