The settings listed on this page are the ones we used for the TCL US5800 review.
We used the 'Movie' picture mode to get close to our calibration goal which gave a warm picture look. 'TV brightness' to 'Brighter' allowed the use of brighter values accessible under the 'Advanced picture settings' menu.
In our totally dark room we set the 'Backlight' to 26. Increase this value to adapt to your room lighting. This won't affect picture quality. 'Contrast' set at 100 allowed the TV to get a little brighter without affecting picture quality. 'Color temperature' is set to 'Warm' but can be changed to a colder setting if you find the overall picture too yellowish. 'Game mode' didn't changed much the input lag from our testing.
The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
Roku offers an application in which you can use to customize the color space, the 2 point and the 11 point.
