What is the Rainbow Effect? The DLP 'rainbow effect' is an artifact unique
to single-chip DLP projectors. The artifact appears as a rainbow or
multi-color shimmer briefly noticeable when changing focus from one part of
the projector screen to another. It appears as a secondary image that
appears at the viewer's peripheral vision and is generally noticeable when
shifting focus from a high contrast area or bright object. For a quick
video sample of the effect, click here (warning: 5MB video).
3-chip DLP projectors, higher wheel speeds, 7-segment color wheels, and
archimedes color wheel designs (pending) are minimizing or may altogether
elminate the effect.

All you have to do is look at a DLP. You either have it, or you don't. You
don't 'catch' it. You are born with it.

And you can't go just by the number, thinking higher is better. This is not
necessarily the case.
When I bought my HLP-5085, the mainstay for a long time was the HD2. Then
TV's came out with the HD3 chipset, which was not in fact technologically
more advanced, but packaged cheaper so manufacturers could sell TV's
cheaper.
The HD3 was, in fact, inferior to the HD2 in most cases.
The high-end at the time, which is what my TV has, was the HD2+. I think it
is still the high-end except for the new 1080P sets. I'm not sure what the
chipset number is for them.
The HD2+ also uses the 7 segment color wheel, improving contrast.

Samsung is also now making an LED-based DLP. It uses 3 LED panels
instead of a lamp and color wheel. But the initial reviews haven't
been raves (well, at least CNET's). Maybe it just needs maturation?
Samsung and Sony recently announced a mfg partnership which should present
us with 46" and 52" LCD's at a very low price in the very near future.
Right now the only REALISTIC choice is Plasma, PERIOD. (can you say 6hrs a
day for 27yrs?). That 50" Plasma Samsung is REALLY interesting for <$1500.

Sounds like a smokin deal, but I've never been a fan of Samsung
plasmas. They seem to me to be an LCD company (where they are
strong) that also makes everything else. But not do those too well.
But maybe they're better than they were when I looked at them a
couple years back. I'd go with the tried and true Panasonic 50" for
$2000 now.

And I see burn-in on Plasma's in stores all the time.

Only the old CRT based rear-projections use 'guns'.
