Subject :
	Aten CS1784 - DDC/CI

Description :
	According to the description of this KVM switch, it buffers the DDC-data - the EDID of the monitor. Does the switch permit DDC/CI communication?

Solution :
	The CS1784 does not permit DDC/CI communication. Video DynaSync is used on un-selected ports only, and DDC communication for the selected port passes through. The selected monitor communicates with the PC directly, and the un-selected monitor communicates with the KVM’s EDID buffer.
