Let me check with our graphics team about what you are seeing. Can you let me know which graphics driver version you have installed?
At the time I posted this I was using version 3071. I have since updated to 3165, and with this version, I can save the settings in a profile and apparently the profile persists through a reboot.
Can you explain though why the IT content function disables the TV's 3D functionality.
@Dudemeister "Can you explain though why the IT content function disables the TV's 3D functionality."
That is a good question and I am currently researching the answer. This is particularly interesting when considering checking the IT box to "On" enables the display to use it's own video quality processing, "Off" and the Intel HD graphics driver does the processing.
I thought it was the other way around, IT ON lets the PC control the display, and OFF lets the TV have control.
