I've been a bit unlucky with this as I've started suffering from the rainbow effect later in life. I don't consciously see it very often but I do find even 4 and 5 speed 7 segment DLP projectors a strain to watch for more than about an hour without a break. |
That is exactly my experience and I am of mature years (sounds better than old) and my tolerance has decreased to the extent that I was forced to part with my Sharp XV-Z21000, not due to rainbows, I only saw the odd one. My problem is eyestrain. I have put more hours on my Sony HW10 in 4 months than I did in a year with the Sharp.
I am hoping that the problem will not be present when the 3 LED single chip DLPs eventually come out.
