As the two schemes yield different 10-bit symbols, a receiver can fully differentiate between active and control regions. When DVI was designed, most computer monitors were still of the cathode-ray tube type that require analog video synchronization signals. The timing of the digital synchronization signals matches the equivalent analog ones ...
