SETTING UP THE DDC VALUE
DDC (Display Data Channel) is a series of protocols that enables plug and play communication between a
graphics adapter and a computer monitor. It allows the display to communicate its supported display
modes and display parameters to the graphics adapter.
The DDC emulation mode will need to be set on the transmitter card (RGBT/DVIT) before plugging a PC
into the RGBT/DVIT card. If the DDC is subsequently changed then a full re-boot will need to occur to
allow the DDC change to take effect.
1. Ensure that the PC is off or not connected to the RGBT/DVIT card.
2. Set the DDC emulation mode depending on your system configuration:
LCD:
Emulate display with digital (DVI) input and output.
CRTA:
Emulate display with analog (RGB) input and analog (RGB) output.
CRTD:
Emulate display with analog (RGB) input and digital (DVI) output.
3. Connect the PC to the RGBT/DVIT card and power on the computer.

Please note: The DDC setting can not be set and applied while the PC is on and
connected to the RGBT card. Please ensure that the PC is not connected or is
turned off when changing the DDC.
