1 ATI Avivo� HD is a technology platform that includes a broad set of capabilities offered by certain ATI Radeon� HD GPUs. Not all products have all features and full enablement of some ATI Avivo� HD capabilities may require complementary products.
2 While the ATI Radeon� HD 3870 Mac & PC edition does support 30-bit digital display under the Mac OS, display output is limited to 24-bit and below.
3 Some resolutions are limited by the performance of the attached monitor and some custom resolutions require user configuration.
