Display Resolution Modes
When power is applied, the monitor is initially set for a display size of 640 by 480 pixels. With a multisync monitor the user can switch the monitor resolution on the fly by using the BitDepths and Resolutions modules in the control strip or the Monitors & Sound control panel.
Table 3-6 shows the display resolution, vertical and horizontal scan rates, and maximum pixel depths supported by the accelerated graphics card with the ATI 3D RAGE 128 GL graphics controller. The 16 MB of video RAM on the accelerated graphics card supports pixel depths up to 32 bits per pixel at all resolutions.
