Apple AMD/ATI Radeon HD 5870 1GB for Mac Pro .

What version is the mini display port on HD 5870 ?

The Vantech adapter will support 60 hz at 4k

Its working with 4k at 30 hz but 30 hz is unacceptable for my enviorment.

It does 2560 x 1920 at 30 hz refresh rate. I m using LG 4K with hdmi 2.0 and

Vantec VLink Mini-DisplayPort 1.2 to HDMI 2.0 4K Active Adapter.

I cant find any information on MDP version of the card. Any information or advise is appreciated.

MAC PRO 2009

32 GB

HIGH SIERRA.

Thanks,
