ORIGINAL POST:
So after following this thread, I'm thinking of finally replacing my 6 30" Cinema Displays with one or 2 8k displays. They have finally gotten cheap enough that it's worth a try. The question is, what graphics cards support 8k displays on the Mac Pro (mine is a 7,1 and currently has a 9100WX with 6 display ports that I dont think will do the job)?
The new AMD Radeon 6xxx series supports HDMI 2.1 (which supports 8k) on their native cards but apple's version seem to be only HDMI 2.0, which is astounding as they would have had to have worked more to cripple their displays:
So one option is to ignore the apple offerings and just get one of the PC AMD 6000series cards with a confirmed 2.1 HDMI port. Or perhaps apple's cards do have HDMI 2.1 or can drive 8k monitors?
I was thinking of getting this 8k display and maybe some of these adapters would work?
or these together might be better:
And might need this software to help:
This TV seems pretty nice and is currently $2900 and $500 amazon kickback, so $2400. Seems like a killer deal.
Has anyone tried any of this to work? Appreciate any pointers or thoughts.
