EDIT LEARN
The KVM is designed to learn the connected monitor’s EDID upon power-up. In the event of connecting a new monitor to the KVM, a power recycle is recommended. The KVM will indicate to the user the EDID learn the process by flashing the front panel’s LEDs. When the LEDs stop flashing, the EDID learning process is done. The monitor must be connected to the video output connector located in the console space at the back of the KVM during the EDID learn the process. If the read EDID from the connected monitor is identical to the current stored EDID in the KVM then the EDID learn function will be skipped.
