I have the same problem.
When a calibrate my monitor with a colorimeter it is fine.
When I turned off my monitor the display settings are changed.
How can we solve this kind of problem?
Hello, look my post here: Please, new implementation in next release of driver (disable hotplug displayport function....)
the "problem" is inherent to the specific displayport ..... because when monitor is turned off or disconnected, the operating system reconfigure default settings (like a new monitor).....
