G804 is designed with two processing modules of G802. It can serve as one quad channel processor or
two independent dual channel processors. It is designed for professional curved screen edge blending as well as
image warping, stacking, projection mapping…etc.
8 inputs (4x HDMI, 2x DP, 2x VGA) and 4x HDMI outputs are designed in G804. Input supports up to
7680*1200 @30Hz, 4096*2160 @60Hz with 4:4:4 full color sampling. Output supports up to 2048*1080 @60Hz.
It is integrated with 10-bit high end processor, motion adaptive de-interlace, low angle smooth algorithm, 3:2/2:2
pull-down and supports non-VESA standard input timing for connecting with various input sources.
Advanced warp technology is embedded in G804. User can use IR controller or WebGui to perform edge
blending and sophisticated geometry alignment up to 9x5 grids and 17x17 grids from Gwarp3 PC tool through
USB or Ethernet. Selectable grid pattern size and various colors and styles are embedded. Corner Wall image
adjustment for mapping image at 90 degrees corner and Linearity Grid Line Adjustment are new function in
geometry alignment. Separate RGB gamma correction for edge blending region color fine-tune, individual color
correction for each output, color uniformity and 9 regions non-edge blending area black level uplift are also
standard functions in G804. Users can see real time geometry and color adjustment to get optimized result.
HDMI 2.0 loop out supports daisy chain connection up to 7680*1200 @30Hz / 4096x2160 @60Hz and
allows large display with multiple G804 cascaded. Video wall function in G804 is to crop and allocate source
image for each projector and set overlap pixels for edge blending. Complete curved edge blending can be
achieved through remote controller and Ethernet without PC software, video distributor and splitter.
G804 is designed to support programmable EDID and non-VESA standard input. User can create any
EDID timing in the range between 1024x768 and 3840x2400 in order to optimize video performance.
Using G804, users can replace high end projector with low cost projector without lens shift, warp and edge
blending. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.
Dual power supply system was designed in G804. User can use either AC 100V-240V power supply or
external DC 12V 2A power supply. When apply AC power supply, user will have one DC 12V 1A output for signal
extender. Standard delivery will pack with AC power cord only.
