Multi-Monitor 4K60HDR RX570 ... only with 30Hz, if more than one monitor

Hey AMD/ATI - Community

...I have an Radeon RX570 with 8GB setup with 3 Samsung U28R554UQU Monitors. (using 3 dedicated Displayportcables plugged direct to the card)

If I use only one Monitor... I have 60Hz.

If I use two or three Monitors.... I have only 30Hz.

As far as I could see, there ist only DP 1.2 on the Monitors. But I can use one Monitor in 4K60Hz with HDR turned on (10 Bit with FullRGB). So it looks like to me, that it is possible to use that settings with Displayport version 1.2.

Could it be that the Displayports on the radeon are not dedicated? ...As far as I could see on the Radeon RX570 it supports Displayport version 1.4.

It would be great to get some answers... Is it possible to have a three monitor-setup with 4k60hdr with an radeon rx570?

if the rx570 isn't good genoug... which card would be good enough?
