Firestar1 :
I have a question, what are the numbers :48 41 50? I don't see any other settings really besides brightness contrast and gamma.
The RGB is kinda hidden.
Below the Gamma presets 1.9/2.2/2.5/Gaming you will see the Colour Temp Presets.
While switching between the Colour Temp presets, when you reach user, the option to adjust it appears. It looks like an -> arrow inside a box or door? The other settings like Normal/Warm/Cool do not have the that right arrow box option...
