DDC Learning
DDC provides plug-and-play capability to your displays. When you plug a display into your
computer, the DDC table in the display tells the computer the optimal resolution to use. In
order to preserve this plug-and-play capability, we have integrated DDC learning into all of
our DVI Solutions.

and hold both the Input Select and Output Select buttons
simultaneously for 3 seconds to enter learning mode. The
red LEDs will read LErn.
