there's so many different version of DLP, that it really depends on the set
there's 4,6,8 segment colorwheels
1x,2x,4x,6x wheelspeeds
units with seperate red, blue, and green chips
and all sorts of improvements such as darkchip
you'd really have to see the actual set itself, there's good and bad DLP televisions and projectors
and is there even a 1080 native resolution DLP chip yet?
last time i looked (i'll admit it's been a few months) WXGA was the closest TI had gotten, and DLP sets claiming 1080P were actually WXGA chips (which is admittedly very close) but i'd take a true 720P native resolution set over a WXGA native resolution set any day. I personally see very little difference between 720P and 1080i, haven't seen 1080P anywhere other than the blueray demo at best buy, which looked like ass, but i KNOW the set wasn't set up right.
