3 Helpful tips for installation and operation
3.1 Before system installation, please consider how to access GeoBox for video wall settings. User can put
GeoBox in front of the video wall to do the setting, then install it to control room.
3.2 If GeoBox is installed at a location that is not easy of access by remote controller, please extend IR
extender to a place for easy IR access. Each G-405 will be equipped with two IR extenders. User can
extend the cable distance up to 20m through audio cable or cut and connected with Cat 5/6 UTP cable.
Each UTP cable can connect with two IR extenders for module A & module B.
3.3 To reset GeoBox to make sure no unexpected setting inside before use. Procedures to do system Reset:
OSD Menu [Options][Reset][Reset All]
3.4 To set [Menu Time Out] to “0”, the OSD will appear while the whole adjusting period.
3.5 Control Hotkeys on the front panel are only functional while the OSD menu is not activated. Once the
OSD menu is activated, these keys will be served as OSD functional keys.
3.6 Toggle on [INPUT] key can select input ports. The result will be showed on the screen.
3.7 Toggle [OUTPUT] key can select output resolution for the LCD. All TV should have the same resolution
for easy installation. The output resolution should be the same as LCD native resolution.
3.8 Toggle on [CH R/L] key will circulate the OSD control between channel RH and channel LH.
3.9 Toggle [CH ID] key can identify RH/LH channel display locations.
3.10 Toggle [Profile] can show Profile Index # saved by user. User can press [Enter] to select it.
3.11 Toggle [INFO] key on the remote controller can see Input and Output display timings and system
information.
3.12 OSD Lock / Unlock: When continuously press [MENU] key in Front Panel or IR Remote Controller for 5
seconds, the OSD function will be locked. To press MENU key for 5 seconds again, it will unlock OSD. It
is convenient for system setup. After system is Power off/on again, it will be at [Unlocked] position.
3.13 Picture menu in the OSD can only be activated while the input signal is not in color [Preset Mode]. To
select [Image Properties] [Custom] [Save], then user can activate [Picture] menu again.
3.14 [Image Setup] menu will not be activated if the input source is not from VGA.
3.15 Once finishing one video wall setting, user can apply the same setting value to next project with the same
configuration. It will save time for the installation and settings.
3.16 G-405 has two processing modules to allow user to display dual contents from dual signal sources or
single content across complete video wall. If one content display across whole video wall is required,
please make sure the input signal shall be connected to Up/Down Modules at the same time through
loop out port, PC dual outputs or HDMI splitter.
3.17 The relation between signal resolution and video wall dimension:
User can do quick calculation of the watching distance by the pixel pitch in the display. For instance, one
47” LCD panel will be about 104cmx58.5cm. If user has one 4x4 video wall with this LCD panel, the total
image size is around 4.16m (1.04x4) x 2.34m (0.58x4). If user applies one f ull HD signal to the video wall,
the display pixel pitch will be around 2.2mm (4160mm/1920). In this case, the ideal watching distance is
about 2.2 meter. If the pixel pitch is 3mm, then the recommended watching distance will be 3 meters.
