Description:
hardware information-gathering tool for VESA PnP monitors
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.
