yes, there should be several folks subscribed to this list that can
talk about their experiences.

yes and no. in stereo mode, you will have the two images for left and
the right eye displayed at the same time. in the first case they are
shown as alternating (full picture) frames and in the second case in
alternating scan lines. that means, you will have to turn stereo mode
off. but then the image will be normal.

yes.

no. it is "ok" for large and dense objects, but letters and thin lines
look funny, often bordering on being unreadable since each eye sees a
different half of the picture.
you can get an impression by clicking on
"Display->Sterep->RowInterleaved" or
"Display->Sterep->ColumnInterleaved"

yes.
