It's the pixel clock that's throwing your monitor out of whack. The only method I could find to get it in the right range months ago, was to first set the basic info to 5040x1050, 57HZ, then change the advanced dropdown to CVT reduced blank. That will change the pixel clock to around 320ish... then change the dropdown right back to manual, edit the rest of the settings and test it. Should work then.
This was the answer...I went straight in on 180.43 (no CUDA step), choosing CVT reduced blank before then changing it to manual and setting mattsimis' settings. All seems fine now (and I'm not on the 'updated' GXM Matrox support were giving out).
