Vizio M Series Calibration Settings Keep Changing
I have a 2017 Vizio M70-E3
The calibration settings on my M-Series seem to keep changing. Particularly, the following changes don't seem to stick
1. Color resets itself from "Calibrated*" to "Regular"
2. Backlight value jumps up (Auto brightness control is off)
3."Clear Action" turns back on from off.
This seems to be associated with a change in inputs. I two devices (Tivo Bolt and Apple TV 4K) attached to it and frequently use the built-in smart tv apps, including Plex, Amazon, and Netflix. I thought that maybe the settings were dependent on input but I've tried manually changing them with each input and they don't seem to stick.
This is an extremely irritating problem. Is there something obvious I am missing?
Thank you for taking the time to respond.
