/sys/class/drm/*/edid . You really don't want to do i2c from userspace
if you can possibly avoid it.

But thats (unfortunately) exactly what I have to do because the device isn't running Linux.  :-(

I knew it was I2C, but on what bus and 'how do I get there from here'?
It would have to be on the video interface/card(s) right?
