I recenlty got a new computer that has a Radeon 6870 video card. I just tried to add a 3rd monitor, but I get no output.
My first 2 monitors are on DVI. I have a mini displayport to DVI adaptor but I get no output from either port. The adapter (HIS) is eyefinity approved and is an active adapter. Is there a way to test the port or adapter? I want a 4th monitor so I orderd an active displayport to HDMI adapter that should be here Thursday.
I can't find any "enable display port", or anything like that in the CCC.
Am I missing something? THis is my 2nd adapetyer. THe first one I got was from best buy. IT was an apple brand but it didn't say if it was active or passive.
Thanks for any feedback,
