and settings. In the event of difficulty or anomalous results, first check the

following basic items:

• Cable connections

• The video format associated with each input

• The timing selected for the display device attached to a particular

channel

• Any system options currently in effect

• Use the command line interface to query the current settings of the

parameter in question to determine Quadra’s current values.

Some of these items are discussed in detail in the “
