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

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.
