I bought a new monitor 24'' to add to my 2 other monitors (24'' and 26''). They're all 1920*1200, and are all recognized individually, and 2 at the same time can always work (through HDMI et DVI1). My graphic card is an ASUS HD6950 2GB and it has 2 mini Display ports as well as 1 HDMI and 2 DVI. I tried to connect my 3rd monitor through DVI then through the mini display with an adaptor, and in both cases it's recognized but when I try to get to activate the 3rd screen, here's what I get:

  • In Windows resolution config Windows error
  • In Catalyst Control Center Catalyst error

Thanks for your help!!

With that card, you can't use both DVI ports and the HDMI at the same time.

Also, if you want to use mDP to a DVI monitor, then you need an "active" adapter.

From the manual of a version of your card, here's a chart of acceptable display configurations (second one from the bottom is the 3x DVI monitor configuration your aiming for):

More info here: Active vs. Passive DisplayPort adapters the truth

Including this tid-bit:

Eyefinity requires an ACTIVE adapter to enable a third monitor on HD 5000 cards. Passive will NOT work, except for the first two monitors on the eyefinity 5 and eyefinity 6 cards. For the other three/four monitors, active is still required.
