Re: Samsung PNxxB550
The entry level (ie B450 and B550 series) plasma sets do not have CMS, blue-only or Cal-Night/Day controls this year. The same may be true of the 550 series and lower LCDs, I’m not sure. The 6 series and higher (all display types) do have these controls.
To calibrate the entry level stuff, you’ll want to use the WB Movie menu that’s in the Factory menu (not the service menu).
