Is this mode possible to support macOS 11.0 Big Sur?
I can't get DRM woking on iMac 13,2 + GT730Its a little unclear what version of macOS and SMBIOS you are using. With 10.15.6 beta, and SMBIOS
set to iMac13,2, the boot argument shikigva=256 works for AppleTV. I believe this may be software
coding. You probably need to set Nvidia as the primary GPU in BIOS, and may need to disable the
IGPU in BIOS. I don't have problems with dataport using a GT730 Kepler, but it wont work with my
2560 x 1080 monitor on any video port. It works on all ports with a 1080p (1920 x 1080) monitor.

See the guide below.I have lots of HDMI output devices but none of them work, any idea what I should look into to find a fix please?

And one news, Catalina is the lastest versions we can upgrade
Remember that the Mac Pro 6,1 was Ivy Bridge based and still has Big Sur support. Came out in 2013. Another possible choice of SMBIOS that may work is iMac 15,1 which is the late 2014 27" iMac. T2 won't be a factor with either of these SMBIOS. There are more Macs without T2 chips that still have support in Big Sur than Macs with a T2 requirement. Will be a long time before T2s are in all supported Macs. We know for sure the Polaris based AMD cards will work with Big Sur. The 2nd gen Nvidia Kepler cards will need to be tested. We can discuss that here once the public beta comes out.It may work with
an iMacPro1,1 SMBIOS, but we'll have to see how tight the
security is, and whether it requires a T2 chip.

Everyone should recall that the Developer Beta is under NDA so even if you are a dev and try it out you'll need to wait until the public beta in July to post about your findings here.
I'm pretty sure that iMac 15,1 will work if you have a dedicated graphics card. Not sure why they dropped support for iMac 14,2 as that 2013 iMac is first gen Haswell. They kept support for the 2013 Trashcan MP which is Ivy Bridge Xeon based. They kept support for the 2013 MBP. "The interior of the 2013 MacBook Air has been updated, with a new fourth generation Intel Core i5-4250U processor." If the MBA 2013 with a dual core 1st gen Haswell CPU can run Big Sur why not the 2013 iMac ? It's got a quad core 1st gen Haswell CPU. The 2013 MBA has HD5000 graphics. The 2013 21.5" iMacs have HD5200 Iris Pro. Makes no sense at all. Maybe it's just a mistake from the marketing dept.i am hoping the 710 will work fine if not i'll try the onboard one but i doubt it might work too so fingers crossed
