Streaming Methods
There are three methods described in this section for streaming video from which to
choose with the Sun XVR-4000 graphics accelerator. All are subject to
-outputs
port mapping (see “
-outputs
Port Mapping” on page 38). The following section,
“Setting Up Streaming Methods” on page 42, describes how to set up these
streaming methods.
Single Video Output Stream
■
Benefits – Maximum resolution (1920
×
1200) and/or sample density
■
Drawbacks – None
Use the
fbconfig -outputs
option to choose the 13W3 output port for receiving
the video stream, or to enable the same video stream to flow out of both 13W3
output ports.
Two Video Streams Sharing a Large Frame Buffer
Two outputs are active where one large frame buffer is displayed across both display
devices.
■
Benefits – Two monitor support without the use of Xinerama software.
Can move windows between screens or span a window across screens.
■
Drawbacks – Fewer samples per pixel are available when the frame buffer
memory is used to support twice as many pixels.
Both resolutions and sample densities must be identical.
