    Are the newer batches of the 20" Aluminum iMac shipping with 24bit screens? I ask because I was talking to Apple Support the other day, and the guy said I could return my 20" iMac and the new one which I would get would not have any issues with color banding.

    Can someone confirm 24bit screens on 20" version?

    My new 20" iMac arrived last Friday (shipped Sept 26th). I can't confirm if it has a 24bit panel in it, but running LCDTest doesn't show any of the lines/bands that my MacBook shows with the same gradient tests. Maybe they have just improved the dithering algorithm, but the gradients are nice and smooth.

    It's definitely still a TN panel though (there is a big variation in brightness if you change the vertical viewing angle).

    Does it still have the color shift from top to bottom? If you display a colored sticky and slide it form top to bottom does the color change?

    Thanks for the replies guys! So that means it still ships with a TN panel. So there's no point in returning it. :(

    All well except the 24" is an LG.Philips S-IPS not a PVA. Same difference though, both 8-bit
