The graphics data sent to the digital monitor use transition minimized differential signaling (TMDS). TMDS
uses an encoding algorithm to convert bytes of graphics data into characters that are transition-minimized
to reduce EMI with copper cables, and DC-balanced for transmission over fiber optic cables. The TMDS
