http://www.wow-one.com/forum/topic/31812-editing-your-configwtf-for-wow-1121/ You could try changing some of the settings in config.wtf. I'm pretty sure 21:9 wasn't foremost on Blizz devs' minds when they were making the vanilla client but maybe there's a way to manipulate the settings to make it look good. I just noticed your reply a minute ago - it's possible that the retail WoW client modified your config.wrf somehow. Glad it's working for you...

Ok, thanks guys. I uninstalled Blizz client but whenever I do buy this monitor, maybe I'll reinstall retail to somehow get classic to recognize the aspect ratio. I'm hoping for the Acer Z35 as its 2560x1080 requiring less gpu power. Thanks again
