A:Answer Dar,
If you like the settings, no calibration is needed. We have four pre-set calibrations, including "Dynamic" (which is usually too bright unless you have a lot of light in the room), as well as "Standard" or "Movie" which is best for most household settings.
Best Buy does offer a calibration service and that may also be a service you might see is right for you.
Thanks for your interest in Samsung products.
