This applies to Windows XP and MXWendler version 4.0 and above with NVidida graphics

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 an NVidia horizontal span.
