Non-standard aspect ratios?

[wadark]

For multi-display setups, does WoW support non-standard aspect ratios that would allow you to run the game on multiple monitors?

[None]

As long as your video card supports it (Eyefinity), then it'll work properly.

WoW will support whatever is plugged in and if you video card can support it then it'll work fine, I'm not really sure how spanning looks without eyefinity, but the aspect ratio would be pretty strange and stretched.
