Increasing Samsung TV 2017/2018 line image brightness EVEN MORE?

[Cr4z33]

I am wondering if someone here has already dealt with a Samsung 2017/2018 line LED TV and image settings for MagicMirror?

I ask because I am not a novice with TVs, but the default image menu doesn’t look to give me enough options to increase the brightness as I expected… :expressionless_face:

Perhaps I’ve got to access any hidden/service menu to do that? :thinking_face:
And if yes how EXACTLY ?
