Any of you guys running Window 7 in 64 bit mode using DX10 and more than one monitor. I have been having a problem when I go 3072 by 768 or higher all three monitors go black. I have tried changing the Flat Panel Scaling and also changed the settings in Matrox programs, still no glory. I have also tried different drivers and went in the register and forced some settings, along with changing some dlls files.
