“White Balance” Settings

Can anyone explain to me the different intent of the High Level (Gain) and Low Level (Offset) settings in White Balance?

Bright and dark screen areas?

Coarse and fine graduation of the settings?

Contrast and Brightness?

I know that Samsung say “suck it and see” but it would be nice to know which ballpark I am taking aim at

Hi @100pat  Basically in White Balance Settings  you are adjusting the amount of red, green and blue, the three primary colours that white is composed of. to give the most accurate configuration .Once set correctly the greyscale,  i.e.is the transition from black to white in shades of grey, should be smooth with no discolouration.  However  whilst you can experiment with settings for best picture (maybe aiming for just below middle values) really more geared for professional calibration who have greater knowledge as thought naked eye is not best guide for this setting.  You can use some expert recomendations but these will not necessarily be applicable for your environment.   (though there are tools available)   If does not work out can always reset to defaults .     https://www.techhive.com/article/2079503/easily-calibrate-your-new-hdtv.html

Thanks for taking the time to reply, James, but I was really asking if anyone knew the difference between the two available options, Gain and Offset i.e. the different meanings of “High” and “Low” level intensity in the context of the White Balance settings on my EU55RU7400 telly.
Kind regards, Pat.

Hi @100pat ,  from what I have been able to determine the gains adjust the brighter part of the picture similar to contrast control, and the offsets adjust the dimmer parts of the picture similar to the brightness control.
