DDC(4)			 BSD Kernel Interfaces Manual			DDC(4)

NAME
     ddc — VESA Display Data Channel V2 devices

SYNOPSIS
     ddc at iic? addr 0x50

DESCRIPTION
     The ddc driver provides support for accessing the VESA Display Data Chan‐
     nel Version 2 supported by many video displays.

BUGS
     This driver does not provide any mechanism for access from user applica‐
     tions.  Its only use at this point is to provide a means for framebuffer
     device drivers to query monitor description data (EDID) using a special‐
     ized in-kernel API.  No support for sending control commands to display
     devices is provided.

SEE ALSO
     iic(4), ddc(9), edid(9)

HISTORY
     The ddc device appeared in NetBSD 4.0.
