Step 4. On the Output Setup tab, you will now see a pop-up labeled "Output 1 of 2" that allows the selection of
each multihead output for editing. Below this pop-up is a label stating the actual resolution of this output. In
a 2x1 Output setup, this will be ½ of Mbox's FullScreen Mode resolution. Below this you will see two tabs
labeled "Texture" and "Keystone/Warp." The Texture tab will be set correctly for you, but may be edited as
required to adjust image position and scale. If you set a positive overlap (you can have a negative overlap, if
desired) on the Output Setup pane, you will see information on the Vignette settings below the Texture
settings. The Keystone/Warp tab is for editing those specific attributes once they are applied.
Projection > Output Setup > Texture
The Texture settings define the manner in which the Available Texture gets applied to the physical video output to
work properly with the multi-head setup of that output. Available Texture is defined here as the result of all layers
composited together on this output of the server and will be the same size as the FullScreen Mode resolution for this
output of Mbox.
The Available Texture is force-fit (stretched or squished) to fit into the Context, therefore the Context size values have
an effect on the overall force-fit sizing of the image. By default the Context size is the same as Mbox's FullScreen
Mode resolution and the same size as the Available Texture. Note that changing the Context size width or height will
result in the Sample Origin X, Width, and Height changing values to maintain the correct aspect ratio. In general, the
Context size should not be changed, and any sizing should be handled by adjusting the Sample size.
The Sample refers to the area of the Context that is shown on the final rendering surface for this output in the multi-
head setup. By default, the Sample size will be equivalent to the actual output size shown below the output selector
pop-up. Depending on the output type, the Sample will be sized as follows:
+ Single Output: same size as the Context.
+ 2x1 Output: 1/2 the size of the Context.
+ 3x1 Output: 1/3 the size of the Context.
+ 2x2 Output: 1/4 the size of the Context.
As with the Context size parameters, adjusting the Sample size will affect the size of the image on screen.
