read-edid - 3.0.2-1.1+b1 main

read-edid consists of two tools:
.
get-edid uses a VESA VBE 2 interrupt service routine request to read
a 128 byte EDID version 1 structure from your graphics card, which
retrieves this information from the monitor via the Data Display
Channel (DDC).
.
get-edid uses architecture-specific methods for querying the video
hardware (real-mode x86 instructions on i386, Open Firmware device
tree parsing on PowerMac) and is therefore only available for i386 and
powerpc architectures.
.
parse-edid parses this data structure and outputs data suitable for
inclusion into the XFree86 or X.org configuration file. It is available
for any architecture.
