    Active mini display port

    Hi all am looking for a bit of advice on buying an active mini displayport adapter and am not sure which one and why one I have already bought does not work.

    I am running a HD7850 and trying to get eyefinity working so I can run 3 monitors I have 2xVGA monitors and 1xHDMI I currently have the HDMI in the HDMI port 1 of the VGA's in the DVI port with an adapter and I was looking at connecting the 2nd VGA to the mini display port via the active adapter and a DVI to VGA converter.

    I have tried this however the monitor is detected by the card but does not come off standby I am using Startech Mini DisplayPort to DVI Active Adapter which is similar to HIS Active Mini DisplayPort the only issue I see is that when using the VGA to DVI connector it has 4 pins around the horizontal pin that the active adapter does not have is this the issue? As the only active adapter I can find with these holes is one for a display port not mini display this one HIS Active DisplayPort

    A lost and confused.

    Althire.

    Which 7850 is this? I think we need to reorganize this question into a more approachable angle.

    Why not just buy a DisplayPort to VGA cable/adapter? You are trying to do DisplayPort -> DVI -> VGA which does not work because Display -> DVI is likely DVI-D only aka it is only passing through the digital signal. It doesn't make sense for manufacturers to make a DisplayPort -> DVI-I cable/adapter because they assume anyone who want that would just buy an DisplayPort -> VGA cable/adapter instead (if it is even possible to make one).

    The 7850 I have is http://www.msi.com/product/vga/R7850...r-2GD5-OC.html and it does not have a display port only 1xHDMI 1xDVI and 2xmini display port and I can't find an active mini display port to VGA only one I found does not say active and according to eyefinity you need an active adapter?

    Go down to the L1 apple store and see if they still have these: http://store.apple.com/uk/product/MB...o-vga-adapter#
