Recently my housemate got the idea to upgrade to a new gaming PC and wanted to add a third display to perhaps do some fancy gaming across all three displays on his HD 5970 card. This is what we learned during the past few days: - Each screen in an Eyefinity setup needs to be the exact same resolution and ratio (4:3, 16:9, 16:10), as each screen in an Eyefinity group will be assigned the same resolution. My housemate has two 4:3 1600x1200 and one 16:10 1920x1200 displays. Eyefinity can not work properly with this configuration. - Eyefinity supports just two 'legacy' (VGA, DVI, HDMI) connectors per Eyefinity setup. If you want to use that third DVI port you're screwed. If you want to use a DVI monitor, you're going to need an active Displayport to DVI adapter, not a passive one. This wasn't indicated anywhere except embedded deep inside the bowels of the AMD site. - Eyefinity can only use the outputs on one card in a CrossFireX setup. So in the end, no Eyefinity for my housemate until he shells out another 500+ Euro for new 16:10 screens. Conclusion: Eyefinity is a nice gadget for the obscenely rich and/or those who are doing a super-upgrade of their entire gaming system including displays anyway. I'd also suggest going all DisplayPort with Eyefinity as well. Saves a lot of trouble and extra adapter costs (100+ Euro/adapter). AMD's PR department really should learn how to properly market their technologies, now my housemate feels rather iffed about the whole ordeal as I imagine quite a few others will be as no reviews even mention this problem of requiring an active DP adapter and such. Of note is also that such adapters aside from being expensive are rather hard to find here in the Netherlands (we had to find an Apple iStore which had one), so that definitely doesn't help matters. Anyway, what are your experiences?
