tomka / write-edid

# Writes EDID information over a given I2C-Bus to a monitor.
# Use: 1. write-edid.sh <bus> <data>
#      2. write-edid.sh <bus>
# The second variant expects data on stdin.
#
# You can find out the bus number with ic2detect -l. Address 0x50
# should be available as the EDID data goes there.
#
# This script expects ascii information representing chunks of hex data
# as input. The bytewise presented data should be separated by spaces
# and/or line breaks. For instance, this is the digital (!) EDID data
# for a Samsung SyncMaster T220 monitor:
#
#   00 FF FF FF FF FF FF 00 4C 2D E5 03 32 32 57 54
#   0E 12 01 03 80 2F 1E 78 2A EE 91 A3 54 4C 99 26
#   0F 50 54 BF EF 80 B3 00 81 80 81 40 71 4F 01 01
#   01 01 01 01 01 01 7C 2E 90 A0 60 1A 1E 40 30 20
