    Different than the other dual monitor black screen setup threads I've seen here so far (at least I haven't been digging around enough)

    Went from an HD5670 to 6670 (one step up for median tesselation support)

    I have 2 monitors, one 1920x1080 and 1680x1050 (like Ali_93's thread). The 16:10 monitor is a Vison 21.6" LCD that I picked up 3 years ago during Black Friday (when 16:10 was still the norm :p), and the 16:9 monitor is an Acer G215HAbd 21.5" which I picked up a few days ago. My :Windows 7: PC will boot fine from POST to login, but that's where it stops; Screen goes black once it finishes loading up the startup services. I am POSITIVE that it is driver related, for 10.6 worked on my 5670 before I made the switch.

    I've tried switching the cables around (VGA, DVI-DVI, DVI-HDMI) and no dice. I am unable to rollback the drivers to the last previously "supported" drivers as the 6670 cannot use drivers under 11.1 (it will not work in the 11 range). The 10.6 HDMI/DP support is installed, but I dunno if that provides much help to the situation.

    I do not want to have this old paperweight sitting on my desk, nor do I want to put in another painstaking investment to find another 16:10 monitor (the 1080 I have is going to be swapped with a 16:10 monitor that my acquaintance is willing to swap (that and I am more inclined to use 16:10 resolutions in games)).

    If there are ANY solutions please post any suggestions that might pertain to the problem ;O)

    Edit: If anyone is going to ask for faulty ports, I can 101% guarantee you it's not, for this problem has persisted on the old 5670 with 11.1 to 11.3

    Edit 2: Been reading around, it maybe the DVI cables. I am not sure what kind of DVI plug on the old monitor. It could be using a DVI-I or DVI-D. As for the cable itself, it is a DVI-D cable.

    Edit 3: Forgot to put the status of the monitor if it's turned on. Standard fare, the monitor is on with the active (blue) status light, yet no display. I do remember encountering this problem in the past with the same monitor, however I forgot how I solved it. Damn.

    Breaking update, I was able to have the monitor come out of the black screen, but I had to force the 1080 resolution on it.

    For SOME weird reason, with 11.4, the drivers cannot support the native resolution on the monitor, or any other resolution that is not forced on it. It maybe the monitor itself I really do not know, anyone who can enlighten me on this topic please do.
