DDC switches

When the DVI-D source device boots up, it uses the Display Data Channel (DDC), a two-way communication protocol, to obtain Extended Display Identification Data (EDID) from the display device. This allows the source to output a resolution that matches the capabilities of the display.

A bank of three switches allows the user to determine how the source device will obtain the EDID. The EDID can be obtained directly from the display device, or from the internal memory within. The three switches are:

EDID Minder — This switch must be on for the EDID Minder function to be enabled. The factory default for this switch is the

off position.
