DDC(4) Kernel Interfaces Manual DDC(4)

NAME

ddcVESA 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 framebuffer 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.
