Optimize GPU resolution and drawing performance
This chapter describes how to optimize the GPUs performance when positioning displays.
C.a.
Definitions
-
GPU
Output board consisting of two outputs.
-
Output
Physical DVI output.
-
Display
D
estination where the picture will be displayed. For example, it could be a single display
or a projection surface composed of one or several outputs.
Usually there is one display for each
output.
-
Canvas
Total drawing area. Displays are placed inside a canvas.
Note: Using display splitters enables having more than one display for one output.
C.b.
Automatic optimization
In the
GPUs
menu, select a GPU and click
Optimize
.
The automatic calculation optimizes the graphic card performance with the current display setup.
If the displays are not side-by-side horizontally in the show composition, using the automatic canvas
optimization gives the best results.
C.c.
Canvas and coordinates
Canvas is the drawing area defined in coordinate system, it is not a pixel space.
Canvas coordinates are in 0.0 - 1.0 range in both X and Y axis and origin is in left bottom corner. A display is
positioned in the canvas by setting display X and Y position, display width and height and rotation.
Use the display wizard to set display grids easily.

Display coordinates are independent of the display resolution and physical aspect ratio. X and Y in display
positioning point to the left bottom corner of the display.
-
X and Y in layers point to center of the layer.
-
When scale and scale height are 1, the layer fills the entire display.
-
Layer aspect ratio control adjusts the aspect ratio of content.
-
Layer scale controls layer width and height while keeping aspect ratio constant.
