Matthias fixed the EDID ROM of his Samsung monitor using the Bus Pirate. He documented the whole process on his blog. Also included is a tip on how to connect the Bus Pirate to I2C line through the VGA, or DVI cable.
This post is about fixing a broken EDID ROM in a monitor. There are several ways to do this. Typically this involves writing the EEPROM with the Windows only tool PowerStrip (see here for a HOWTO) . Here I want to present an alternative solution using the Dangerous Prototypes Bus Pirate – a device which every hardware hacker with self-respect should have anyway. You should already be tech-savvy to attempt this procedure.
