8.4.3 Warping – Screen size
About (Warp) Screen Size adjustment
If the used screen aspect ratio is different than the projector aspect ratio, e.g. source is 16:9 and projector is
16:10, then black bars will be projected. In the example case a black bar on top and bottom of the image will
be projected. The warp area contains not only the image information but also the black bars. If we want to
position e.g. the active left top corner exactly on the screen using 4 corner warp, then it is very hard to do that
as we are moving the black left top corner and we do not have control over the exact position of image left top
corner. By moving the outline of the warp screen size to the active image information, the corner points of the
warp area are now exactly on the corner points of the active image information and makes warping much
easier.

the screen aspect ratio or actual measurement in cm, inches or any other unit.
