I am currently using 14.12, but I can try with the 14.9 drivers.
I am using the Startech adapter on all 4 MiniDP ports, but I am only allowed to have 3 monitors active at any time. It can be any combination of monitors, but only 3/5 monitors are allowed to be active at any given time thru CCC or windows. How do I get them all to be active at the same time?
Startech MiniDP to HDMI (MDP2HDS)
I also have a couple that are probably not active but I tried anyways, nGear MiniDP to HDMI (59727) http://secure.ncix.com/products/productdetail2.cfm?sku=59727&promoid=1416
And the one that came with the card, which appears identical to the nGear ones, just black instead of white.
I think the nGear adapters and the one that came with the card are just passive adapters.
I’m using an active adapters on all 4 other mindp ports and a DVI cable for the 5th. I still can’t run more than 3 monitors. in CCC it asks me to disable a monitor to activate another, and the same in windows.
