Caution
!
Danger of damaging the monitor!
If you want to set higher frequencies and resolutions, first make sure that the
monitor you are using is suitable for a higher frequency and resolution.
If the frequency is too high, this may damage the monitor.
You can plug an additional graphics card into one of the ISA or PCI slots on
the bus board for special applications (see Chapter 4.3).
A PCI graphics card should be used because it provides a faster image
building rate.
Proceed as follows:
1. Switch off the PG 760 and the monitor.
2. Plug the monitor cable into the VGA socket of the graphics card.
3. Connect the monitor cable to the monitor.
When the PG 760 is switched on, the system automatically recognizes the
additional graphics module. The built-in VGA graphics interface module on
the mother board is switched off. To switch the built-in VGA graphics
interface module back on, proceed as follows:
1. Switch on the PG 760.
2. While the PG 760 is being powered up, keep the INSERT key depressed
until you hear two signal tones.
The additional graphics module is reactivated the next time you switch the
PG 760 on without pressing the INSERT key.
