Yes, retrying always fixes the problem. And for the purpose of getting the latest monitor values from time to time to keep the UI in sync, this suffices.

I'm more surprised that I2C works at all over the long, thin Thunderbolt cable of my LG. Huge bandwidth going through it for video and the USB hub, lots of current passing through for charging the MacBook at the same time, I'm amazed it works so well.

Is it actually I2C over the Thunderbolt cable? I had assumed it was I2C just between the CPU and video hardware on the motherboard.

It is really I2C over whatever cable you have between your monitor and your computer.

I don’t know how they multiplex it through the Thunderbolt little wires but it does work.
