Widescreen Gaming Forum

Firstly, apologies if this has been asked before, it seems to be a common topic and I have read through the stickies above but I am still unable to figure out what the heck is happening.

Basically, I have an ATI 6970 card, this has 2x Mini Displayport's and 2x DVI's, now from what I understand the way I am supposed to use eyefinity is that I must use one DisplayPort and two DVI's.

The monitors I am using are all the same, Benq G2420HDBL, these contain only DVI or VGA ports, nothing else

My Primary monitor is plugged in via DVI on the card and DVI on the monitor.
My Secondary monitor is plugged in via DVI on the card and DVI on the monitor.
My Third monitor is plugged in via Mini-Display Port on the Card, then through an Apple Mini-Displayport to VGA adapter (I am lead to beleive this is ACTIVE) and then into my third monitor via VGA cable.

Now my first two monitors work fine with DVI, but my third monitor fails to find any kind of signal, here is a list of things I have tried.

1) Replace the apple mini-displayport to VGA adapter with another identical one.
2) Replaced the VGA cable.
3) Tried swapping the monitors around to check the monitor isn't faulty.
4) Re-installed the ATI drivers.
5) Rolled back Windows 7 to yesterday.
6) Totally reinstalled Windows 7.

Also, if I remove all three monitors, and add my old dell monitor and then add a new monitor on the displayport to VGA adapter then it works with two screens, but here is the real confusing part, yesterday, this was working, but now it just will not detect the display.

Does anyone have any suggestions that might help? I am kind of desperate now

Thanks,

Rich

Don't merely guess that the adapter is active. A lot of adapters are NOT active. Also, many of the more ignorant shops don't know the difference and will give you bad information. Not a good idea to mix DVI and VGA port types. It breaks DHCP. Get a standard mDP to DVI active adapter from someplace like Newegg and run all three displays via thier DVI port.
