Got the
Powercolor DP -> DVI
Now my 3 monitors are connected as follows. (3xBenq 2200LED HDMI)
Mon1 Left, DVI -> HDMI
Mon2 Middle
Powercolor DP -> DVI ->
HDMI (standard dvi to hdmi cable)
Mon3 Right DVI -> HDMI
So after buying that Powercolor _Active_ DP to DVI it finaly works good with the new drivers and well colors are a bit better because of the Digital signal instead of the VGA that I used with the apple dongle. To bad I had to buy the damn overpriced clicktronik DVI to HDMI but nothing was in store. (poor Sweden without any cheap display cables)
So this upgrade cost me 600kr for the powercolor active dongle and about 300kr for the damn branded 5m DVI to HDMI.
(Swedish kronor) so thats about 90$ for the DVI dongle and DVI to HDMI cable.
Bottom line, Apple MiniDP to VGA does not work anymore so my final word is do not buy it or you will loose about 20$ for nothing.
Best Regards
Commander
