I am sensitive (very) to rainbows... so while DLP front projection tends to have slightly better black levels (if you have the kind of room that allows you to see it) LCD technology, with its 3-chip panels and lack of color wheel makes for a much better picture.
DLP has positioned itself to protect the overpriced "high-end" 3-chip systems from becoming affordable (as of now anyway) they are (I imagine) afraid that once they allow those prices to drop, then there will be no real difference between the high-end cinema projectors and home projectors, save lumen output.
Right now LCD and LCoS/SXRD/LCoS have 3-chip systems - no color wheel needed.
With DLP, why is it that I can buy THREE single-chip DLP projectors for a grand total of $3000, but I cannot get a single 3-chip DLP projector for less than $15,000?
Rant over, lol.
