Higher resolution not available for DX11

[Erron]

I am trying to run WoW at 5760x1200 with the support for DX11 enabled.

This works well with DX9, but with 11 I can't select this resolution from the options in game.
The highest resolution I see is 1920x1200.

My other DX11 games run at 5760x1200, like LOTRO

Anyone else seen this?

On a related note has anyone tried enabling the LAA? LARGE_ADDRESS_AWARE ?

Odd. I know I was able to achieve that resolution using nVidia surround just last week. I realize you're asking about ATI
Eyefinity but just thought I'd throw my two cents in.

I can't imagine that giving the executable file more than 2GB worth of memory is going to fix a video driver issue. The guy
in the thread mentions it but he also mentions how he hits the 2GB cap using the eyefinity resolution. Unless you're
crashing because you're out of memory I doubt enabling that will make the resolutions magically appear in the drop down
menu, but I guess anything is worth a shot? While using nVidia surround I didn't even think to look at my memory usage
but I didn't crash so I mustn't have run out of memory even while using 6060x1080 [300 pixel bezel adjustment.]

Updated Catalyst to 11.4
I am able to get the 5760x1200 resolution when I run in windowed/fullscreen mode now.
But still unable to do it fullscreen. Crossfire has little benefit in windowed mode.

Looks like this is an AMD issue not a WoW issue.

That memory issue was not related to not being able to select the resolution in the game.

I installed the AMD CAP application profiles updated 4/29 and the memory issue seems to be gone.

The client running at 5760x1200 ultra settings, and a few addons runs right at 2GB.
Before the update I was crashing in Stormwind near the auction house.
Ran it for an hour today and no issues.

Just going to have to wait and see if 4.2 or the next Catalyst update fixes the fullscreen/crossfire DX11 issue.

Just quick update for all and any who end up searching this (Sorry Erron, not a fix.)

LAA is apparently already enabled with 4.1:
