(Every command was run while the HDMI cable was connected to the Laptop (Dell Inspiron 14 7000) and the Monitor (Acer)

This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 2
No EDID on bus 4
No EDID on bus 5
No EDID on bus 6
2 potential busses found: 1 3
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
256-byte EDID successfully retrieved from i2c bus 1
Looks like i2c was successful. Have a good day.
