I had a similar problem, it wouldn't let me display higher then the resolution on my second monitor, even though it was displaying on my primary monitor.
In the end I used the Nvidia control panel to enable the second monitor to support 1920x1080 (I didn't make the second monitor run at this resolution just enabled it to)
When I opened WoW I could then select 1920x1080.
