If user press [Reset] key in [3x3] adjustment, all the adjustment in [3x3] and [5x3] will be reset
and only [2x2] will be kept.

[9x5] alignment will have the same behavior. If user goes back to low grid alignment, only low
grid alignments will be kept. [2x2] alignment is an exception that can co-exist with other
alignments. Once implement [2x2] alignment, the image corner position will be changed and all
other curve alignments will not be reset.
14.4 How to increase the accuracy of geometry alignment
a
、
[9x5 Curved] will cut the horizontal image into 8 sections and the image in each section can be
independently adjusted. In different output resolutions, there will be different pixel number in
each section: XGA: 1024/8=128, WXGA: 1280/8=160, 1080p: 1920/8=240. Usually, it is enough
for most of the curved screen edge blending.
b
、
If the overlapped area between two adjacent projectors has the same or multiple number as
above, then the manual geometry alignment for grid overlap will have less flexibility. User can
increase or decrease one or two grids (32 or 64 pixels) in overlap area to increase the flexibility
for accurate alignment between adjacent projectors.
c
、
[9x5 Curved] alignment for two projector edge blending area as an example (in 1024 resolution):
If the overlap is 256 pixels (25%) in XGA resolution, total adjusting points are 15. User will have
less adjustment flexibility. If increasing two grids (64 pixels) to 320 overlap pixels, user can have
30 adjusting points to get more accurate geometry alignment. It can align the images from two
projectors on curved screen with good quality without Gwarp PC Tool.

Below is the list for the accuracy of geometry adjustment in different overlap pixels:
GeoBox output resolution 1920*1080 1280*800
1024*768
Min. adjustment flexibility 240/480/720 320/480/640 256/384/512
Max. adjustment flexibility 352/608/832 224/256/384/416/544/576 192/320/448/576
i.
Once the grid between two adjacent projectors can match together, it will make sure to get good
alignment. Horizontal lines between two adjacent projectors should be 100% match together.
Vertical lines are allowed to be separated (i.e. if user uses external grid pattern with 50x50 grid
size, when user applies 32x32 gird pattern, the grids will not overlap together but have the same
