How do I switch from 3D stereo to 2D (monoscopic)?
The simplest way is to turn off the top or bottom monitor. If desired, the half-mirror can be raised into a locked position to get it out of view. When raising or lowering the mirror, make sure that you slide it backward (raising) or forward (lowering) before moving it to a new position. You should not try to force the mirror. It will raise and lower with minimal force if it is first moved to the correct position.
