obscuro, I believe he was saying that in general terms dlp is sharper then lcd. Pico LED projectors do not fall into that category. Given the same lens, a single chip projector will always be sharper then a 3-panel design.
Your assumptions are incorrect and yes most DLP displays do generally have 1:1 pixel mapping (the small LED 1280x800 DLP's being one of the exceptions).
You are saying that wobulation OR diagonal pixels are not used in most DLP displays. Okay.
Do you have any technical references for the TI chips?
Projector Central has published review(s) where the output resolution of the display was not available (from TI). They wondered about the actual resolution of the DLP device because the display was not sharp. And I have been confused by discussions of on this forum about the actual resolution of the DLP chips.
I'm sorry if you thought my suspicions were assumptions.
