Is anybody here with a powerful GPU — either a new Mac Pro / MacPro7,1, or a MacBook with an external eGPU — actually successfully using an 8k display, day-to-day?
I got an amazing deal on a Dell UP3218K, Dell's 8k display. You're supposed to use two DisplayPort 1.4 cables to a single GPU to support 8k@60hz; and I've tried nearly every imaginable combination of GPUs, cables, and ports, and basically no matter what I do, I only see the 8k display a, strangely, *two* 8k displays, in macOS's preferences:
SwitchResX manages to "see" that the display supports 8k, even 8k@60Hz,
Unfortunately, when selected, that doesn't make the second MST "display" disappear, and even at 30Hz — which I should be able to do with a single cable! — the picture is extremely blurry:
I doubt the photo does a very good job of conveying the blurriness — sorry, it's got like 300ppi! I don't think I could photograph it without a nice macro lens, lol. It's extremely obvious in person, though; the text is almost unreadable. )=
Anyway: has anybody had _any_ success with this, in any configuration? If so, what combination of equipment makes this work for you? /=
