Auto Compress
»
Compresses 18Gbps video signals to 10.2Gbps.
»
Must be paired with 2nd KD-FIX418 unit to decompress signal for acceptance by
video display
»
No compression applied to

10.2Gbps signals
➔
Compress
»
Compression applied to all signals (18Gbps, 10.2Gbps, <10.2Gbps)
»
Resultant signal bandwidth is ½ original signal bandwidth
»
Must be paired with 2nd KD-FIX418 unit set to Decompress mode for acceptance
by video display
➔
Decompress/ Auto Down-Convert
»
Decompress: Restores compressed signal to 18Gbps for acceptance
by video display
»
Must be paired with 2nd KD-FIX418 unit set to Compress mode
»
Auto Down-Convert: Down converts all signal > 10.2Gbps
»
Resultant down-converted signal is 4K@60 [4:2:0] 8bit (10.2Gbps)
»
Down-convert mode works independently.
Does not require 2nd KD-FIX418 unit.
Input Boost
➔
When set On, EQ levels of the HDMI input are set HIGH
➔
Slightly degraded signals (ie pixel loss, flickering image) may be resolved
➔
Severely degraded signals may be improved, but may not be completely resolved
»
Use shorter length HDMI cables for best results
»
Maximum one active/directional HDMI cable may be used.
»
KD-FIX418 should be installed at display side for these instances
Control Rotary:
Choose the desired setting for hot plug detection control,
bandwidth compression/decompression, and boost mode.

Forced HPD On/Bypass
➔
In cases of many layers of connectivity or non-standard
devices in-line, hot plug detection (HPD) may be lost or
drop below standard levels, leading to the video source
not detecting a display/sync device and not outputting a signal. A display device may
also not detect a connected source in cases of failed hot plug detection.
➔
If set to On, Hot Plug Detection (HPD) voltage is forced at the HDMI input connection
of the KD-FIX418. The connected source device will be fed a constant voltage to
inform the device that a partner (output/display) is always connected and active.
➔
If set to Bypass, Hot Plug Detection (HPD) voltage is bypassed from connected output/
display to the input/source
Bandwidth Compression
➔
KD-FIX418 can be set to compress or decompress the TMDS (audio and video) signal
enabling 18Gbps video signals to be extended via legacy 10.2Gbps cabling.
➔
IMPORTANT: COMPRESSION/DECOMPRESSION REQUIRES
TWO (2) KD-FIX418 UNITS
»
One (1) unit set to Compression mode (typically at video source)
»
One (1) unit set to Decompression mode (typically at video display)
