Does anyone know or has tried their recent macbook pro with dells 8k (7680 x 4320) display at 60hz (UP3218K)? Pixel bandwidth might not be a limiting factor: - We know it supports 2 x 5k @ 60hz displays.  - Those displays each use a single usb-c thunderbolt-3 port which itself contains two displayport-1.2 signals.  - Displayport-1.2 is capable of 17.28 gbit/s, so four of these (two cables, each with two signals) theoretically supports up to 69.12 gbit/s.  - An 8k @ 60hz runs at 49.65 gbit/s, clearly less than two of these cables at max bandwidth.  - However, 8k @ 60hz does require 7% more throughput than two 5k @ 60hz displays, so that's still an unknown but we have a chance here. My chief concern is the port connectivity: - As mentioned a single usb-c thunderbolt-3 port on the macbook pro has two displayport 1.2 signals. - But Dell's monitor and Philip's upcoming monitor in next 3-8 months both have two displayport-1.3 ports.  - I doubt we can connect one usb-c / two displayport1.2s into one displayport1.3. And then repeated again for the other half. Or shown explicitly: - laptop_usbc0_displayport1.2+displayport1.2 -> monitor_displayport1.3_0 - laptop_usbc1_displayport1.2+displayport1.2 -> monitor_displayport1.3_1 So it seems like some sort of intermediate conversion would be needed to make that work. There are adapters cables on amazon that convert usb-c to displayport, but they all state a max display of 4k@60hz. And furthermore, my concern is that a single cable needs to combine both displayport1.2 signals into one displayport1.3 result before it is provided to the monitor. Existing cables I see on amazon dont mention dealing with these complexities. I do see an adapter (107006-BLK by Cable Matters) that acknowledges the dual displayport1.2 nature of the the MBPs usb-c thunderbolt3 port, but it converts that into two separate displayport1.2 outputs, whereas I would need them as a displayport1.3 output to drive the dell 8k display.
