The important thing is that I2C slave address (x37) is responsive on Linux even when the monitor has been switched to Windows and fails the DDC communication check. It may...

I have hacked in an experimental change that may allow you to send a setvcp x60 request to the monitor even if it fails the DDC communication tests.  The changes...

The fact that ddcutil always detects the monitor reflects the fact that's it's always possible to read the EDID. In fact, it should be possible to read the EDID even...
