Is there a high performance GPU card (RX 480/580) out there with four or more DisplayPort 1.4 ports?
All the latest GPUs seem to be limited to three DisplayPorts.
I have three Radeon HD 7870 Eyefinity to drive six Dell UP2715K displays.
The problem is that the Dell 5K displays require two DisplayPort 1.2 connections on the same GPU.
The Radeon HD 7870 are working okay, but not great; the screens flicker off an on sometimes when I run more than four at a time, and the performance is slow.
I previously had twelve 2880x1800 displays running from two 6870 Eyefinity cards on the same computer with better performance.
I am also wondering if a DisplayPort 1.4 MST to dual DisplayPort 1.2 adapter exists and would work?
