Also, anyone have some tips to improve black level other than the usual because this thing lightens up my room during all dark/black scenes. I know it won't be CRT black but this is pretty bright despite running in Eco mode and having an all black room.
Screen could probably use a low gain instead of the 1.3 106" I currently have. I did get this for free and other than the rainbows and black level I love everything about it so far.
60hz should heavily reduce the likelihood of seeing them compared to 24hz; but like you, I still do see at that framerate.
The wheel spins even faster at 50hz (actually significantly faster - more detail here
) - at which point I see almost none - but few devices allow outputting at 50hz.
Part of the issue with both your black levels as well as rainbows is that you're running very bright with your 106" screen at 1.3 gain. At 106", you could be using below 1.0 comfortably (with 2000 lumens, I'd reserve 1.3 for really large screen sizes - 160" or bigger). A gray screen at that size might make more sense in this regard; and it'd also improve black levels.
The other thing to remember is that the lamp will dim with age: I've found it settles at a significant drop in brightness somewhere between 200 and 300 hours. The result is a bit of an improvement in black levels, and a more comfortably dim image makes rainbows much more difficult to notice.
Failing the above, you could go for an ND filter to drop brightness (once again, good for rainbows as well as black levels).
If all else fails, you might have to look into other technologies: 3LCD projectors are also pretty decent at this price point (Epson 2030 comes to mind). If you want to step up, you could look at the Sony HW40ES which is based on LCOS instead: but it's 3.5 times the price.
