  • Page 45: Edid Management

    Operating the DVI KVM over IP EDID Management The DVI KVM over IP features EDID Management. Before the source can send video (and/or audio) data, the source device (connected to each Sender unit) reads the EDID (Extended Display Identification Data) from the displays which are connected to each Receiver unit.

  • Page 46: Using The Downstream Edid

    Operating the DVI KVM over IP EDID Management Using the Downstream EDID By default, the (downstream) EDID from the display, connected to the Receiver unit, is used. If the internal EDID is being used (see Using the Internal DVI EDID), then use the following procedure to revert to the downstream EDID.
