Writes custom EDID data into HDMI adapter (Linux, I2C)

write-edid

Created by Dr. Ace Jeangle ([e-mail]) 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.

Example

sudo ./write-edid.sh 3 edid.bin

will write file edid.bin with binary EDID data into I2C-Bus #3
