******  The information for many current models of monitors state
explicityly that they are *Non-Interlaced* monitors. They are optimized for
a non-interlaced environment, even if they can handle an interlaced signal.
The problem is in getting the signal interlaced in the first place since
that isn't the way a computer handles the video signal. Many accelerator
cards simply cannot do interlacing at all. If your system won't interlace,
you can't view interlaced 3D on the system, unless you interlace the signal
outside the computer, which some viewing systems do.

********  While that may be true for some cards, I have tried the Total3D
card on several different systems and monitors. Monitors are NOT all the
same. The pixel rate of the video card is not the complete culprit. The
Total3D card has one of the highest pixel rates around, though I don't know
the actual stats. On different monitors, it cannot function at anywhere near
it's capability and the SETTINGS USED HAVE TO BE NO HIGHER than what the
specific monitor supports. I have a very high quality monitor, a ViewSonic
17GS and it cannot handle the full output of the card. Lesser monitors are
even worse. If you want a stereo system you must get a Monitor that
specifically supports high refresh rates. Generally as those rates are
higher, so is the price. Read the specs on any monitor and find out what the
maximum frequency is for Vertical refresh. The monitor will not function or
will potentially break down if you attempt to drive it faster than those
rates. There is a test mode in the set-up that lets you test the operation
of a specific monitor. If it doesn't run at the high rates, you can't use
the high rates.
