Most “experts” and professional TV calibrators agree that the most accurate picture mode 'out of the box' is the "Movie" mode - that is to say, it is the mode that will bring you closest to a properly calibrated display.
Calibrating a TV simply means setting it to match a set of established "standards". When your TV at home is properly calibrated, the image you see on your screen will look as close as possible to what the director of the movie or TV show saw on his monitor (e.g. the Hulk will be the same shade of green on both displays).
If you have been conditioned to seeing a cooler/bluer, more dynamic picture, the "Movie" mode will appear far too "red" and too dim at first (cooler/bluer colors appear brighter than warmer/redder ones). However, give it a few days for your eyes and brain to adjust to the new more accurate settings (trust me, they will). After a few days, if you go back to one of the more "dynamic" modes, you’ll notice that the picture will appear far too bright and too blue.
The "Movie" mode is also the preferred picture mode for viewing HDR content.
you should also set the "Color Tone" setting to one of the "Warm" settings. Most experts agree that the the "Warm" settings are the most accurate.
"Color Temperature" (or the temperature of "white") refers to the color of the light source that's being displayed on your screen.
In order for your TV to adhere to the director's vision, it needs to reproduce white as closely as possible to the ISF recommended D65 (Daylight 6500K) which is similar to ambient daylight at midday (on a cloudy day). D65 is the standard used throughout the film and TV world.
Again, you might find that the "Warm" settings make your picture appear too dim and to "red" (or "yellow"). But once again, your eyes/brain will adjust to the new setting in a few days. I would avoid the "Cool" mode if you want an accurate picture.
NOTE: The different "Picture Modes" are only preset modes that you use as starting points. Once you start changing different settings, regardless of which mode you started in, you have now created a new "Custom" picture mode. Additionally, some advanced settings are only available/adjustable in the "Movie" picture mode.
Now all that said, it does come back to a matter of personal preference. In the end, it's your
TV and your
eyes, so adjust it the way you
