Yep... I know of the contrast change with angle due to the polarizers,=20 but was not expecting a colour shift. I suspect if may be because some=20 colors get affected differently by the polarizer (perhaps due to where=20 they're located relative to the polarizer). FWIW, the viewing angle on this is 55 deg min, and I'm seeing the colour=20 shift at prob around 10-20 deg. I spoke with NH, who is also not sure=20 why, but suggested that they have a version with a higher viewing angle=20 -- if I buy 3000 pcs. Ha! So not really expecting to fix this, so I need to focus on finding a=20 different/better option. Worst case, I could put in a menu to let the=20 user tweak the color, but that's really hokey.
