the TX will begin reading the DDC from the locally connected monitor until a valid EDID table is read.
The table will then be stored on the TX and presented to the CPU.
Advantages: The TX does not need to be connected to the video card or RX.
The EDID table can be loaded before the TX is installed.
Limitations: No communication link from the CPU to the display. This prevents the use of HDCP or
monitor configuration /color tuning and may result in loss of remote video if a display with lower resolution
capability is connected to the RX.
4.2. Load Default EDID Table
Holding the ACQUIRE and SELECT buttons for 5
seconds will reload the default DDC table into the
TX, and switch the DDC mode to Remote Static.
The TX Status LED will turn Orange while the
default table is loaded and then change to Green.
Advantages: Sends a valid EDID table to the
CPU in order for the graphics adapter to boot.
Limitations: Default EDID table may not support
required resolutions.
