Some PC may not follow EDID from GeoBox and show different result. If it happens, please open
resolution setting window and select desired output from PC.

、
User can also set non-VESA standard output timings from PC, GeoBox can accept this kind of
output timing under the conditions that the maximum clock rate shall be under 330MHz and the
resolution shall not exceed 3840x2400.
8 System bandwidth and system crash
Due to hardware bandwidth limitation, it is possible to see some abnormal image during some settings. It is
due to processing bandwidth limitation. It may happen in below conditions:
1.
High resolution input source like 3840x2160 with different video wall ZOOM and Overlap settings.
2.
When implement extreme geometry alignment.
3.
When implement active 3D 120Hz input/output.
4.
We suggest to select the image vertical resolution same as projector. If user uses 1280x800
projectors, then 3840x800 or 3840x1080 signal resolution should be selected to avoid the above
bandwidth issue.
5.
Once it happens, please reset the system and select different settings. Once it normally displays, no
side effect will happen again.
9 Screen Selection
a. Gain value less than 1.5 will be recommended for Edge Blending application. Higher gain value
will be more sensitive to color difference among projectors. In short throw projector edge blending,
viewer may see different edge blending result while viewing at different angles.
b. Motorized screen position may be shifted from time to time. It will affect the image stacking in edge
blending area and may cause blurred image. Fixed screen is recommended.
c. If ultra-short throw ratio projector is used, the screen gain value should be under 1.00. The flatness
of the screen will be also more important in this kind of projector.
10 Projector Selection and settings
a. The projectors for the edge blending should be the same model and the same production lot. If
they are not the same models, it may create some difficulty and performance issue.
b. Usually, higher contrast ratio in the projector will have better black level performance. The
projector with contrast ratio more than 3000:1 is recommended for edge blending. In a dark
