I searched around and didn't see anyone with a similar issue.

I have 2 monitors and a single ATI 5850 GPU, one at 1680 x 1050 and the other at 1280 x 1024. When I start the game in DX11 mode, even though my 1680 monitor is primary, the max resolution I can pick is 1280 x 1024. When I switch to DX9 mode it works as expected. In DX11 mode, if I unplug the second monitor, it also work as expected.

I'm running the latest ATI drivers and Win 7 x64 with all the latest patches, 12 GB RAM, over 1 TB of free hard drive space.

I would love to run both DX11, max resolution, and keep my second monitor plugged in. Has anyone else seen similar and/or have any suggestions?

Thanks!
