I recieved a call today from a friend who was receiving an error message when he was vMotioning a server.
The maximum resolution of the virtual machine will be limited to 1176 x865 at 16 bits per pixel. To use the confurable maximum resolution of 2360×1770 at 16 bits per pixel, increase the amount of video RAM allocated to this virtual machine by setting svga.vramSize=”16708800″ in the virtual’s configuratio file
The quickest way I have found to change this is to edit the VM’s properties and change the video card to “Auto-detect video settings”, one thing to remember is the VM must be powered off to make this change. If you have many VM’s that need changing you could use a Poweshell script to achieve this.
