Windows XP + No output on second screen

This applies to Windows 7 and MXWendler version 4.2 and above

Problem:

• The MXW UI runs, and you see content updating in the output on the first screen, but not on the second ( output ) screen

Reason:

• You have an NVidia graphics board

Solution:

• 1.) Open NVidia system settings
• 2.) Under 'Multi-GPU Acceleration' enable 'Compatibility Mode'

Background:

• If you select performance mode, only the first screen receives OpenGL updates
• This is performance wise the best solution, but you have to split the screen eg. using a Matrox Triplehead or using a NVidia horizontal span
