3 Helpful Tips for system installation and setup
a.
Select digital input to get better image and avoid image position shift.
b.
If 4k signal connection distance is more than 10m, please select a certified HDMI cable to avoid
unstable signal connection. Usually [High Speed HDMI + Ethernet] cable will be better.
c.
The quality for signal adapter or converter, such as HDMI to DVI adapter and DisplayPort to HDMI
converter, may downgrade the signal quality and cause issue. Please select qualified ones.
d.
If user can see blue background image with [Power Saving Mode] message, it means the signal
connection between projector and GeoBox is OK but no input signal detected by GeoBox. Please
check signal source or replace a different input source to test.
e.
If user can
’t see [Power Saving Mode] message or splash screen, please check the connection
between GeoBox and projector. User can connect to a monitor to check the output from GeoBox.
[Loop out] port is for raw signal daisy chain connection and is not an output to projector.
f.
The output resolution setting shall be the same as projector native resolution to get the best video
quality. After geometry alignment, this output resolution can
’t be changed. Otherwise, geometry
position will be shifted and required further adjustment.
g.
In the application with short throw ratio projector on curved screen, it is possible that the image
location is beyond the maximum adjustment range in manual adjustment. In this case, Gwarp PC
tool is required to double the adjustment range.
h.
During installation setup process, please apply FHD signal to the system for easy setup. After
finish the setup, user can select optimized EDID from OSD menu to get optimized video quality.
i.
The optimized EDID resolution should be the final resolution after edge blending. For instance, if
user uses three XGA projectors for edge blending with 250 overlapped pixels, then the best signal
for this setup will be 1024*3-250*2=2572. It means 2572*768 will be the best signal resolution for
this setup. User can customize EDID with this resolution in GeoBox. Some PC may not be able to
output the same custom resolution. In this case, user needs to set PC output resolution as close
this timing as possible. GeoBox can support none-VESA standard input timings.
j.
In addition to the resolution settings, user needs to provide content with the same aspect ratio as
screen to ensure no distortion on the screen.
k.
To reset all projectors before edge blending to get the same settings in all projectors.
l.
To turn off auto keystone function to avoid image shift.
m.
In order to avoid interference among multiple GeoBox during the installation, user can set ID
number for each GeoBox through [Options] Menu. Press number keys in Remote Controller for
the control of multiple GeoBox:
850: simultaneous control for all GeoBox
851: control GeoBox ID No. 1
853: control GeoBox ID No. 3
User will see flashing LED on front panel after press 85x number keys. It means the OSD
menu in GeoBox with flash LED is locked and will not be controlled by remote controller.
n.
OSD Lock / Unlock: When continuously press [OKD Lock] key on Front Panel or [Menu] key in IR
Remote Control for 5 seconds, the OSD function will be locked to prevent from setting change by
