That’s good to hear. To me it seemed like the documentation was wrong because the graphics card page also says that the unreleased W5700X, which is less powerful than Pro Vega II, is able to support three 6K monitors. That didn’t make sense. When I reached out to Apple to ask, no one was able to answer since the Mac Pro is so new.
W5700X can support 3 Pro Display XDRs because it supports DSC. I’m not sure why Vega II didn’t support that ?
