Changing the Screen Resolution

You can change the screen resolution using two methods, depending on the frame buffer you select for the console. One method sets the default console device to the desired resolution. The other method forces the console to be the S24 monitor at a specified resolution.

To Change the Screen Resolution:

1. With the SPARCstation 5 powered on, bring the system down to the ok prompt.

2. At the ok prompt for the console-device selected by the CPU boot PROM, enter:

   ---

   ok setenv output-device screen:resolution
   

   ---

   where resolution is one of the following:

   • r1152x900x66

   • r1152x900x76

   • r1024x768x70

3. To force the console to become the S24 monitor at the specified resolution, enter:

   ---

   ok setenv output-device /iommu/sbus/tcx:resolution
   

   ---

4. To reset the system so that the NVRAM entry overwrites the monitor ID resolution selection, enter:

   ---

   ok reset

   ---

5. To boot your SPARCstation 5 system, enter:

   ---

   ok boot -r

   ---

The monitor is now reset to the specified resolution.
