Guys can someone help out here. I have the 6950 2gb (Gigabyte brand)
3 Samsung 22inch dvi /vga monitors.

OK here goes

I have a dvi cable from the top dvi port to the dvi port on one monitor
A DVI cable from the second DVI port (this cable has a vga connector built in at the other end) connected to the VGA port on another monitor.
The third is connected via minidisplay port to dvi adapter (active) to dvi port on the monitor.

I can only get two screens to fire up, if I unplug any one of the monitos, the other one fires up.

I'm suspecting its the cable with DVI one end and VGA on the other.

Any suggestions?
 
Hmm, I thought it may be too. No brand on the adapter.

Do not post competitor links This is the link, It's a Spanish site as I live in Spain. Heres the product translation below.

Also I'm a complete noob to this but he monitor running off that adapter is working fine.

The new MacBook, MacBook Pro and MacBook Air each have a Mini DisplayPort that allows you to connect an external monitor or projector using an adapter. You can use an external display as main workspace or to extend your desktop or set it in mirrored mode with a projector so you can view what you are watching your audience.

Use the Mini DisplayPort to DVI to connect a monitor with DVI connection.

• Mini DisplayPort adapter DVI-D male to female.
• adapter compact hose 12 cm.
• It feeds on itself Mini DisplayPort connector.
• Supports HDTV resolutions up to 1080p.
• Supports 225 MHz / 2.25 Gbps per channel HDMI (6.75 Gbps to all channels).
• Compatible with 12-bit color depth per channel (36-bit for all channels).
 
OK I just looked at my desktop settings, and I can detect the other monitor although it doesn't recognise what it is and it doesn't give me the option to change the resolution. It gives me the option to extend the display to that screen however when I do this it does not work. It does say however it is connected by VGA. Do you guys think that this may be the VGA portion of the cable causing me problems?

I tried that but no joy, windows control centre can see all three monitors and labels the 3rd one (the one I@m trying to get to work) as display on VGA

The one hooked up through the display port adapter is fine. I'm new to this if you hadn't guessed but if there was a problem with the adapter would the monitor work?

Thanks in advance

That is NOT an active display port adaptor - that is your problem mate

Buy one that says "active display port adaptor" like the OCUK one. I have it and am running an Eyefinity group as I type

Hey BaDBoY thanks for that, just for reference, how can you tell if it is active or not?
