Following method describes how to fix EDID display size information of your monitor if it's wrong (some of Samsung's monitors report incorrect size when connected over HDMI, for example). It assumes that your monitor is connected to HDMI1 port (HDMI-A-1 is full kernel address).
I used following tools:
- Bless
- edid-decode-git
- edid-rw (I used parts of this script for
edid-checksum.py) - read-edid (parse-edid, get-edid)
