Eyefinityu question for MSI 6950 twin Frozr III

[MeMeMeMe]

I am considering getting 3 monitors for eyefinity. Do I still need to get an active DP-> DVI adaptor for the 3rd monitor?
I remember reading that the 6900 series might support 4 monitors, and not need the active adaptor if using 3. Is that correct?

You still need an active adapter.

Or your third monitor would need a DisplayPort input.

This is direct from AMD:

• A maximum of 2 legacy monitors (VGA, DVI or HDMI) can be enabled simultaneously, provided that each monitor is connected either directly or via a “passive” DisplayPort™ adapter/dongle. “Passive” adapters/dongles will NOT support more than 2 legacy monitors.

• To enable support for more than 2 monitors, “active” DisplayPort™ adapters/dongles are required (or monitors with direct DisplayPort™ connectivity must be used).

Some people seem to get away with a passive adapter and some don't. No idea why.

Thanks for clearing that up.

You can get unpowered single-link adaptors now for under £20, and my monitors wouldn't be over 1920x1200, so I'll get one of them.

No problem, but you're going against the recommendation given by AMD.

It may work, it may not.

You pay your money and you make your choice I suppose.

I'm not talking about using a passive adaptor. Back when the 5000 serires first came out, active adaptors were expensive. Sapphire and Dell brought out cheaper ones, which were dual link and required USB power, so there were still expensive. Then they introduced single link active adaptors, which only support resolutions up to 1920x1200, but they are active.
Report from anandtech just before they were first introduced. Note that it is AMD who were publicising and promoting them, so they should work.

OK.
