DDC LEARNING
FRONT PANEL
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 plugand-play capability, we
have integrated DDC learning into all of our DVI Solutions.
