TGA-7000 PMC Graphics Card Installation Guide
To set up single video output, do the following:
1. If enabled, disable doublewide mode.
To disable doublewide mode, type:
host% fbconfig -dev pfb0 -defaults
2. Set the desired screen resolution. For example, type:
host% fbconfig -dev pfb0 -res 1280x1024x76
To find all possible TGA-7000 graphics accelerator resolutions, type:
host% fbconfig -dev pfb0 -res \?
4.2.2 Setting Up Two Video Outputs Over One Large
Frame Buffer
This section describes two monitor support without the use of Xinerama software.
This means that the TGA-7000 PMC Graphics Card creates one wide (or tall) frame
buffer, displayed across two screens using the DVI port.
To set up two video outputs over one frame buffer, do the following:
1. Enable both video outputs, sharing a single frame buffer. Type:
host% fbconfig -dev pfb0 -doublewide enable
• Use the
-doublehigh
option for displays that are set one above the
other (rather than side-by-side as for the
-doublewide
option). Both
monitors must have the same resolution.
• Use the
-outputs swapped
option to reverse the positions of the two
video outputs relative to each other. The default is
direct
. Both monitors
must have the same resolution.
• Use the
-offset
option to adjust the position of the specified video out-
put by the value specified:
-offset xval yval
This is implemented only in
-doublewide
and
-doublehigh
modes.
For
-doublewide
,
xval
is used to position the rightmost video output.
Negative is left (overlaps with the left video output). For
-doublehigh
,
the
yval
is used to position the bottom video output. Negative is up (over-
laps with top video output). The default is [
0, 0
].
