HP-UX Configuration ATI RADEON 7500 PCI Graphics Controller Installation Guide Resolutions ATI RADEON 7500 graphics controllers can support various graphics resolutions and refresh rates as shown in Table 4-1. In addition to these standard resolutions and refresh rates, the ATI RADEON 7500 graphics controller will also support any resolutions and refresh rates that are supported by the specific monitor that it is connected to the ATI RADEON 7500 card. Table 4-1 Standard Supported Video Modes - HP-UX Resolution 1024x768 1280x1024 1600x1200 1920x1200 Color Depths (Bits per Pixel) 8, 24 8, 24 8, 24 8, 24 Refresh Rates 60, 70, 75, 85 Hz 60, 75, 85 Hz 60, 65, 75, 85 Hz 60, 75 Hz Restrictions and Limitations This section provides information on the limitations and restrictions of the ATI RADEON 7500 hardware and software. No Accelerated 3D Support The ATI RADEON 7500 graphics controller does not support accelerated 3D (e.g. OpenGL). Minimum Console Revision The minimum firmware version for ATI RADEON 7500 graphics controller single head support is V1.0 on HP Itanium Integrity systems. Multiple Colormaps Multiple colormaps are not supported. The ATI RADEON 7500 graphics controllers support only one installed colormap at one time. Exceeding this limit will cause colormap flashing, also known as "Technicolor". Applications should not install or de-install colormaps themselves. The window manager should perform these actions. However, the application is responsible for providing the window manager with hints as to which colormaps to install or de-install. You provide this information using the Xlib function XSetWMColormapWindows(). This function sets the WM_COLORMAP_WINDOWS property for a given window. Default Visual Information The ATI RADEON 7500 graphics controller can only support one visual type at one time. Supported default visual types are 8-bit PseudoColor and 24-bit TrueColor. The default depth and visual class is 24-bit TrueColor. To change the default visual, you must edit the Xserver's configuration file which is located at /etc/X11/XF86Config. The depth is set in the Screen section of the Xf86 configuration file. There also needs to be a Display subsection with the correct depth. For example, the following lines will select a 24-bit default depth visual: 18 Chapter 4
