The image below is an example if 2 projectors are projecting at the same image.
1. Horizontally place two projectors and have the two projected images with an overlap area and use the focus/zoom
and lens shift functions with test grid pattern to set a proper overlap area for blending with a matched grid size.
2. Color matching 2 projectors on white is done with P7 (R.G.B.C.M.Y.W) adjust in projector toolset.
3. Brightness matching 2 projectors can be done with the lamp power(Refer to adjustment by dimming the projector with
higher lumen.
4. Use ScenergiX-> White level to set the blending size based on the overlap region size.
Use ScenergiX-> Black level position to adjust the start position of black level compensation.
Use ScenergiX-> Black level to raise the brightness of non-overlap zone such that the brightness of the overlap zone and
non-overlap zone are matched for black level.
Please note that the followingallowablewarp, blanking and ScenergiX combinationbased on the
underlying chip specification
ScenergiX / 4 corner combination is available when black level is not adjusted.
