I've just had a demo of a Seleco 400 CRT and to my amazement i saw a slight rainbowing effect as well!.
I had just demo-ed the HT200 DLP and thought maybe that was fresh in my mind (i saw rainbow all the time). I waved my hand in front of my face as i did with the DLP to force rainbow but that did'nt cause it. It was just blinking etc that caused the slight rainbow.
The saleman asked what i was doing, and when i told him he was gobsmacked. Stating it was impossible to get rainbow with CRT, to which i agreed. But what was i see-ing?.
He was using a high gain stewart screen that produced sparkles with the DLP, so i was wondering if that was causing slight colour shifts etc during the screen scan etc. Anyway after a couple of minutes the rainbow effect totally disappeared!. This was probably due to the projector reaching full operating temp.
Mind you these days I start looking for panel structure and true black levels even when looking out of the window!, anybody know a good shrink...!
