As the Pixel Overlap Slider is adjusted, colored reference outlines of the display overlap area will be
shown in the Edge Blending/Overlap control panel. The reference outlines are provided to show the
overlap effect in the display projectors seam area and the effect on overall available screen size.
NOTE: To enable overlapping, you must ensure the following criteria are met:
1. There must be two display devices attached to your graphics adapter.
2. Both displays must be at the same resolution and color depth.
3. The displays must be aligned vertically and horizontally.
Blending Type
Select the blending method to apply to the overlap region.
Disabled (Overlap Only):
No edge blending will be performed in the overlap region.
Linear:
In the overlap area a linear fade of overall pixel intensity is created from one display to the
next.
Gamma:
In the overlap area, a fade effect is dynamically created based on the gamma values of
pixels in the overlap region.
