Problems with Quadra operation may result from incorrect system connections
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 “
