I currently have an Acer S201HL monitor hooked up via DVI, and plan to buy 2 more of them for a 3-screen Eyefinity setup (specifically Eyefinity, not 3 separate desktops). The thing is, this screen only has a DVI port.

I've been looking at some DVI to Mini DP adapters, and saw different kinds ranging from like $10 to $100+. I basically just want the cheapest one that'll work. This adapter caught my eye (mainly being the lowest priced one):

Encore ENCA-MDD Mini DisplayPort Male to DVI Female Adapter

Pretty much, I'm wondering if it'll work? It doesn't seem to be Active, but I'm not entirely sure if this matters or not (I mean I know it matters in terms of compatibility, but don't know if it'll be incompatible with my setup or not).

There's some Active adapters that are a bit more pricy as well, such as the Sapphire Cable 100924 Active Display Port to Single-Link DVI (not sure if MSI happens to make/recommend their own adapter, don't think it really matters though). Generally put, they seem to be around the $30 range. It seems this will likely have the best compatibility, but I'd rather the cheaper option if it'll work (and work without like halving the refresh rate or some other bs :p and also be compatible with Eyefinity).

Short Version: I'm looking for the cheapest kind of adapter that'll let me hook 2 DVI monitors to my GPU over the Mini DPs for Eyefinity.

Currently, the single monitor by itself with overclocked refresh rate doesn't require Dual-Link DVI, so I take it the adapters doesn't have to support Dual-Link either?

Hmm, is there any particular reason why it's a must? Not that I don't believe you or anything, just wanted some more information :)

I read something like Eyefinity setups need an active port past 2 screens. Wouldn't the DVI port itself count as the active port?
 
If the adapter isn't active, your card won't "think" that the monitor was connected through Displayport signal, but DVI signal, therefor it won't allow selecting that monitor as the main display in Eyefinity setup.

3-monitor Eyefinity setup only require 1 displayport connection, so only 1 active adapter needed.

Ah, cool :)

So, it seems I can buy the 2 extra screens, one passive DVI-to-MiniDP adapter, and one active DVI-to-MiniDP adapter, and have working Eyefinity?

I have a DVI-to-HDMI cable lying around somewhere I believe. I could use this instead of the passive DVI-to-MiniDP adapter for one of the screens (one on DVI, one on HDMI, one on DP via active adapter)? The key thing being, all monitors past the second one (in my case, the third screen) requires an active DP adapter?
