Edge Blend
Edge Blend function requires multiple projectors to simultaneously project on the same screen. Use this function to adjust
the uniformity of image. To use this function, Edge Blend must be enabled on both projectors.
Edge Blend:
Select On to enable this function. Following functions are available when this option is turned on;
otherwise, the functions are grayed out.
Align Pattern:
This function can be used to display the auxiliary lines for displaying the overlapping area; the line is
moved with the value of white level you set.
White Level:
White Level is used to set the overlapped area for blending in multi-projection application, the
overlapping When projecting White, the area where the two images overlap is projected twice the projectors' white
output levels. The solution is to adjust the White Level. First make sure that the units connected to the projectors are
outputting black. Then increase the White Level (Top, Bottom, Left, and Right) until the non-overlap area's brightness
matches the overlap area.
Black Level:
The purpose of Black Level is to increase the black level of non-overlapping area. When projecting black,
the area where the two images overlap projects twice the projectors' black output levels. The solution is to adjust the
Black Level. First make sure that the units connected to the projectors are outputting black. Then increase the Black
Level (Top, Bottom, Left, and Right) until the non-overlap area's brightness matches the overlap area.
Reset:
All the settings toward edge blend will set to default.
Screen Format:
Sleet the screen format to 16:10, 16:9 and 4:3.
