320 and 540 pixel formats
What pixel formats, or "visuals", are supported on the Silicon Graphics 320 and the Silicon Graphics 540?
Both the Silicon Graphics 320 and Silicon Graphics 540 Visual Workstations support RGB and Color Indexed (CI) formats, as well as overlay windows. However, the list of available pixel formats changes depending on display settings (see Display Properties->Settings from the Control Panel). Note also that, depending on the display mode, some OpenGL features (and acceleration) may be disabled. See the program "wglinfo.exe," included with the Graphics Software Development Kit listed below, to get a list of available pixel formats.
RGB modes
See the online documentation that comes with the Silicon Graphics OpenGL SDK for more details (SDK link below).
