Case study:
➢
Below are the procedures to crop and set 3328*1440 output timing from 3840*2160 input source and
split into four 832*1440 resolution outputs for LED controller.
➢
G904 output settings shall be the same as LED module resolution to get the best video quality.
Please set 832*1440 as the output resolution in each channel through programmable output setting.
Video Wall settings
ZOOM
: H= 4, V= 1, to split horizontal pixels 3840 into 4 sections, each section with 960 pixels.
PAN: to assign the split image section to each LED.
OVERLAP: The required resolution is 832 pixels and split image is 960 pixels in each section.
We need to use Overlap function to adjust the cropping location for each LED.
LED-1:
PAN
: H=1, V=1
Overlap: RH edge: 832-960=-128
Bottom edge: 1440-2160=-720
LED-2:
PAN
: H=2, V=1
Overlap: LH edge: 960-832=+128, RH edge: 832*2-960*2=-256
Bottom edge: 1440-2160=-720
LED-3:
PAN
: H=3, V=1
Overlap: LH edge: 960*2-832*2=+256, RH edge: 832*3-960*3=-384
Bottom edge: 1440-2160=-720
LED-4:
PAN
: H=4, V=1
