System connection: One G-703 is required for three projector edge blending. Please connect the
signal source to CH-1 HDMI input port, connect CH-1 HDMI loop out port to CH-2 HDMI input port and
connect CH-2 HDMI loop port to CH-3 HDMI input port.

Excel Spread Sheet is available to for user to determine the projectors (resolution, quantity, lumens
and throw ratio) and information for system installation (single projector image size, overlap area size,
installation distance and optimized content resolution…). Based on this information, user can make
detailed project plan for the complete system.
c
、
Placement of the Projectors:
Select projectors with higher contrast ratio (above 3000:1 is recommended) and set projectors at
reasonable distance from the screen with 200-500 overlap pixels (or 30cm-50cm overlap width)
between two projectors.
Use removable tape as temporary marks to indicate the image edges for each projector and
screen center line (based on the data from Excel Spread Sheet). Each projector should have the
same display size. Otherwise the grid size in each projector will be different and the blending
image will become blurred.
To display each projector a little over the display range for further geometry adjustment.
Please try to install the projector with less keystone image.
To set parallel vertical overlap edges between 2 adjacent projectors and let the positions of the
lines close to pre-marked positions will get better video quality.
d
、
Projector setting:
Reset projector to default setting.
To disable “Auto Alignment” function if user wants to use VGA analog input signal to avoid image
shift during projector switching ON/OFF process.
Disable Auto Keystone function.
Select a Display Mode with 2.2 gamma curve will reduce the color difference in overlap area. User
needs to test with different Display Mode setting based at final color fine-tune stage.
Use projector internal color adjusting function to adjustment the color variation among projectors
before implement edge blending.

、
G-700 Setting
Reset GeoBox to default setting.
Select output resolution to be the same as projector native display resolution.
Set [OSD Time Out] to [OFF] to maintain the display of OSD and Grid Test Pattern during the
installation period (default is in [Off] position).
To do [Color] adjustment for each projector if necessary.

、
Geometry Adjustment:
Please familiar with OSD operation from front panel and remote controller, including activate grid
pattern, channel selection, shortcut keys for [Warp], [Video Wall], [Edge Blend] and [Info].
[OSD Time Out] is default to ”0”. It will ensure the grid pattern will not be turned off automatically.
If multiple units of GeoBox are used and IR receivers are put together, please set [Box ID] for
each G-700 so that user can control each G-700 separately.
