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 Channel Version 2 supported by many video displays.
BUGS
This driver does not provide any mechanism for access from user applications. Its only use at this point is to provide a means for frame-
buffer device drivers to query monitor description data (EDID) using a specialized 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.
