I have 2 x 3Ghz Quad-Core 2008 Mac Pro with an ATI Radeon HD 5770 and an NVIDIA GeForce 8800 GT driving four DELL 2007FP displays (two in portrait and two in landscape mode). I need to use a VM ware windows machine and PACS software that uses each of the displays for a specific purpose: navigation, reporting, and image display (x2). The display numbering in the virtual machine depends on the host (mac) display initialization sequence, which seems to vary between one power up and the next. Therefore, every time I turn on the mac and launch the windows VM, I end up with a different display layout and I need to reconfigure the windows desktop and reassign the functions of the displays in the PACS software.
Is there a way to force the initialization sequence of the displays on the mac to be always the same?
