A:Answer While the picture is somewhat dependent on your source material, note there are no consumer calibration tools for 4K sets at this time. Also note, using someone else's configuration settings are never a good idea as, again, it depends on their source material and room lighting, etc.
Thus far, I've gotten the best picture results from the set's standard picture mode without additional adjustment as opposed to the other available modes including gaming when gaming. I also turned off motion control as it seemed to cause occasional picture stuttering which became distracting after awhile.
