I am using a monitor adapter to supply the sense code,
but I only get one resolution, even though I have a
multiscan monitor. Why?
¥ If the adapter is conÞgurable, you need to adjust it to
one of the multiscan options that best matches your
monitor. If the adapter is not conÞgurable, you need a
new adapter with the proper sense code for a
multiscan monitor.
I have a monitor with three BNC connectors. Why won't
it work with my XCLAIM VR card?
¥ Monitors that only have three BNC connectors
require a synchronization (ÒsyncÓ) signal to be sent
down the green line. This is called Sync-on-Green
(SOG). ATI accelerator cards do not output an SOG
signal. Adapters are available for your Macintosh to
convert the separate sync signal from the ATI card to
an SOG signal for the monitor. Check with your local
Apple Authorized Dealer for availability of SOG
adapters.
I have a monitor with Þve BNC connectors. Why won't it
work with my XCLAIM VR card?
¥ For a cable with Þve BNC connectors, ensure that they
are all connected to the monitor. If only three of the
cables are connected (i.e., R, G, and B), the monitor is
expecting a Sync-on-Green (SOG) signal.
¥ Some monitors may have a switch to set the monitor
to either SOG or separate sync. If the switch is set to
SOG, the monitor will show a scrambled display.
Setting the switch to separate/composite sync may
resolve the problem.
¥ A number of BNC cables, even though they are
designed for Macintosh computers, do not supply the
sense code needed by the graphics card. Using an
adapter which sets the appropriate sense code should
solve the problem.
