  To change the monitor refresh rate:

1.

Open MGA Monitor in the Windows NT Control Panel.  The MGA

Monitor Selection dialog displays.

2.

Select the appropriate monitor from the Monitor List.  If your

system’s monitor is not listed, select one with a maximum refresh rate

matching the one your system uses.  An MGA.INF file will be created

in the SystemRoot\SYSTEM32 directory.

Note:

In a multiple G95 configuration, the MGA.INF setting affects all

monitors.  Intergraph recommends that the monitor you select in

MGA Monitor be compatible with the least-capable monitor

used by your system.

➤

 To test the new monitor selection:

1.

Open Display in the Windows NT Control Panel.

2.

Select the resolution and pixel depth you want to test.

3.

Select Test.  If the display is satisfactory, go to step 6.  If not,

continue.

4.

If your monitor does not display a stable test screen, the parameters

set by the MGA.INF file are not suitable for your monitor.  Select

Cancel to close Display.

5.

Run MGA Monitor again to select a different monitor.
