I am running an ATI 5870 using 3 monitors in Eyefinity. My desktop resolution is set at 5760x1080. Everything there is working perfectly. However, when I load up WOW the highest resolution I can choose is 2400x600. Any ideas why?
I posted on the Wow forums as well and got this response, tried it and it still didn't work.
What happens if you alter the config.wtf file in the world of warcraft folder? It's in the WTF folder, open it with notepad, look for "SET gxResolution" and make it say:
"SET gxResolution "5760x1080"
You should probably only have to change the resolution numbers that are already there. Save and close the document, restart wow.
