I have a new iMac with Windows 7 Ultimate (32-bit) and an ATI Radeon 4850. I'm experiencing an issue with color quality. Gradients appear banded, photos don't look as good, and color depth looks more like 16-bit than 32-bit.

Windows reports the current color depth is 32-bit and that the driver is the most up-to-date version.

I spoke with Microsoft and AMD. It's probably not a Windows issue. It's probably something with the BIOS or display driver. AMD doesn't make the driver's for the iMac onboard Radeon card, instead Apple makes that driver as OEM according to AMD. Does anyone have experience fixing this problem???
