About Monitor Sensing

Apple’s Monitor Sensing specification allows video display

cards to identify the attached monitor. The RADEONMAC® EDITION auto-configures itself according to the monitor sense code detected and enables all resolutions supported by the

monitor. Since the RADEONMAC® EDITION relies on this sense code to correctly auto-configure during startup, the monitor must supply the appropriate sense code.

On VGA monitors, the RADEONMAC® EDITION card uses the Display Data Channel (DDC) protocol, which is similar to Apple’s Monitor Sensing specification, to determine the possible resolutions and frequencies. All possible resolutions are shown in the Monitors & Sound control panel and the Apple control strip.

When using older VGA monitors without DDC, you must choose the resolutions supported by your VGA monitor in the VGA Monitors section of the ATI Displays control panel. See “VGA Monitors” on page 18 for additional information.

If you are using a display adapter and the adapter supplies the sense code information for only one resolution, then that resolution will be the only one available, even if the monitor supports multiple resolutions. A resolution of 640x480 is usually the default resolution. Therefore, when using an adapter to supply the sense code, it must be designed to supply the proper code for the monitor you are using it with; otherwise, the RADEONMAC® EDITION cannot correctly auto-configure itself for the attached monitor.

Although the RADEONMAC® EDITION card does not output Sync-on-Green (SOG) signals directly, adapters are available that can overlay the Composite Synchronization Signal and send it through the Green video signal line so that you can use an SOG monitor. Monitors requiring an SOG signal usually have only three BNC connectors (RGB).
