I went to Edgewater, NJ to see ROTS on DLP and they had an old first generation projector. Must have been an XGA (1024x768) because the pixel structure was horrible. Colors were dull compared to the film presentation I'd seen the week before, and the bulb was obviously beyond its rated lifespan because the picture was exceedingly dim.
HD broadcasts on my home projector (Optoma H79, 1280x720 DLP) easily beat ROTS on the DLP in Edgewater.
If Obi-wonton saw it on a more recent Barco, it probably was as stunning as he says.
