Created by Dr. Ace Jeangle (support@chalk-elec.com) based on script from Tom Kazimiers (https://github.com/tomka/write-edid)
Writes EDID information over a given I2C-Bus to a monitor.
The script expects root permissions!
You can find out the bus number with:
ic2detect -l
Address 0x50 should be available as the EDID data goes there.
- Use -h (--hexadecimal) option to provide EDID file in text form written as hexadecimal numbers.
- Use -b (--binary) option to provide EDID file in binary form. This option is used by default if filename suffix is
.bin - Also, the --binary option is usable if the file is input on stdin.
sudo ./write-edid.sh 3 edid.bin
will write file edid.bin with binary EDID data into I2C-Bus #3
