3 HP OpenVMS I64 - Graphics Software Installation and Customization This chapter provides information for installing and modifying the software required to support 2D and 3D graphics with the ATI RADEON 7500 PCI graphics controller under the HP OpenVMS I64 operating system. The ATI RADEON 7500 PCI graphics controller is directly supported by OpenVMS I64 without additional software. Bug fixes and new feature support are supplied using the standard OpenVMS downloadable patch support mechanism, and with new versions of the Operating System. The behavior of the ATI RADEON 7500 PCI graphics controller's support software may be modified after installation on OpenVMS by editing the appropriate files and issuing DCL commands (see "Multiple Graphics Cards Support" on page 10). Video Resolutions Supported The ATI RADEON 7500 PCI graphics controller is capable of supporting the graphics resolutions, color depths, and refresh rates shown in Table 3-1: Table 3-1 Supported Video Modes - OpenVMS Resolution 640 x 480 800 x 600 1024 x 768 1024 x 864 1152 x 864 1280 x 1024 1600 x 1200 1792 x 1344 1856 x 1392 1920 x 1080 1920 x 1200 1920 x 1440 2048 x 1536 2048 x 2048 Color Depths (Bits per Pixel) 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 8, 16, 24 Refresh Rates (Hertz) 60, 72, 75, 85 60, 72, 75, 85 60, 70, 75, 85 60, 70, 75, 85 60 60, 72, 75, 85 60, 65, 75, 85 60, 75 60, 75 60, 75 60, 75 60, 75 60, 65, 70, 75 57 The video mode chosen should match your monitor's capabilities. In general, refresh rates below 70 Hz are discouraged on CRT monitors, as they tend to show flicker based on the lighting source and surrounding equipment. Flat Panel displays generally prefer a 60Hz refresh rate. The available resolutions are monitor dependent. The default video mode is 1024X768 @70HZ and 24 bits per pixel depth. Chapter 3 7
