Hi, thanks for getting back so quick.
I'm not at the office at the moment so I'll re-check when I am, there may be an issue there as I thought I'd tried earlier only to have to roll back because there was no 3D settings in the control panel afterwards. When I inherited the pc viz.FULLSCREEN implemented stereo 'flickering' on a monitor but QUAD_BUFFER still produced the
VisualChooser error!?!
Of course this is presuming that QUAD_BUFFERing is what I need to be using for the Vuzix?
