We monitor what our immersed subjects are seeing in their VR4 a couple of
diferent ways:
1) T off of the MCO composite out and view on a Sony monitor that accepts
component video input, or
2) use a harmonic research box to convert either the mco output, or the
output socket of the VR4 box (which produces NTSC component) to composite
video where we can then direct it to a VCR or TV.
The new V8 boxes are a different beast. They have an output socket that
drives a digital monitor, so you either have to use a VGA type monitor, or
use a scan converter to drive a TV or VCR.
