Yesterday, I found myself in Costco looking at a 50" plasma that I had been waiting on for a couple of months. They had it in a less than stellar viewing environment, playing a DVD with muted colors. So, what does this have to do with DLP? Well, as a norm, I have a very uncooperative saccadic masking condition which usually easily allows me to see DLP rainbows. On every front projection setup, to a varying degree, I can see rainbows without trying to look for them. Its bloody annoying, because it rules out DLP as a projection technology until 3xDMD becomes affordable to me.
Anyway, while standing there in Costco and right beside this 50" plasma is a 62" DLP RPTV. Its showing a different DVD that has strong colors (Finding Nemo) and I was impressed with the picture considering the material being shown and the environment. I kep looking back and forth between the plasma and the RPTV and then it struck me: where are the rainbows?
Ok, maybe my viewing angle isn't sufficient to provide a great-enough 'arc' for my eyes to sweep and catch the RGB separations. Maybe its the ambient lighting in combination with the DVD material to reduce or minimize the threshold of awareness of RBE, or is it something else? Ok, so I move closer to the 62". Now, I am standing maybe 6-7' and the screen-widths is on the order of
