Footnotes 

1. AMD HD3D is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Additional hardware (e.g. 3D enabled panels, 3D-enabled glasses/emitter, Blu-ray 3D drive) and/or software (e.g. Blu-ray 3D discs, 3D middleware, games) are required for the enablement of stereoscopic 3D. Not all features may be supported on all components or systems - check with your component or system manufacturer for specific model capabilities and supported technologies.
2. AMD App Acceleration is a set of technologies designed to improve video quality and enhance application performance. Full enablement of some features requires support for OpenCL™ or DirectCompute (including AMD’s Unified Video Decoder (UVD)). Not all products have all features and full enablement of some capabilities and may require complementary products.
3. Blu-ray 3D playback requires additional stereo 3D hardware and software.
4. AMD Dynamic Switchable Graphics technology requires either an AMD “A” series APU or an Intel processor, plus an AMD Radeon™ discrete graphics configuration and is available on Windows® 7 Professional, Windows® 7 Ultimate, Windows® 7 Home Premium, and/or Windows® 7 Home Basic OS. Linux OS supports manual switching which requires restart of X-Server to switch between graphics solutions. With AMD Dynamic Switchable Graphics technology, full enablement of all discrete graphics video and display features may not be supported on all systems (e.g. OpenGL applications will run on the integrated GPU or the APU as the case may be). Always check with your system manufacturer for specific mode capabilities and supported technologies.
5. AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for spanning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. AMD Eyefinity technology can support up to 6 displays using a single enabled AMD Radeon™ GPU with Windows Vista® or Windows® 7 operating systems – the number of displays may vary by system design and you should confirm exact specifications with the applicable manufacturer before purchase. SLS (“Single Large Surface”) functionality requires an identical display resolution on all configured displays.
6. OpenCL compliant SDK and driver release scheduled for later in 2011.
7. Accelerated transcoding requires application support for AMD App Acceleration. AMD App Acceleration works with applications designed to take advantage of its GPU acceleration capabilities.
8. Digital rights management restrictions may apply.
9. Upscaling subject to available monitor resolution.
10. Adobe Flash video acceleration and post-processing is supported for H.264-encoded content. Requires Adobe Flash Player 10.1 plug-in or later version.
11. Requires Blu-ray movie disc supporting dual 1080p streams.
12. Playing HDCP content requires additional HDCP ready components, including but not limited to an HDCP ready monitor, Blu-ray or HD DVD disc drive, multimedia application and computer operating system.
13. Some custom resolutions require user configuration.
