In the Video sync page, you can adjust several parameters like brightness, saturation and intensity to customize the sync effect to your preference. These values are saved independantly for each sync mode (Cinematic, Vibrant, Relaxation, Rhythmic) and apply to all lights in the TV area (including the TV backlight strip).

Brightness:

The brightness level of the lights. 

Saturation: 

The color saturation of the lights, from washed out (left of the slider) to most vibrant (right of the slider).

• You may want to try different saturation setting when watching in SDR or HDR to see which saturation level fits best to each video format. 

Intensity:

A combination of the transition speed betweenc colors and amplitude of the brightness change, from soft (left of the slider) to intense (right of the slider).

• When the Intensity is set to the lowest, the lights will remain at the same brightness regardless of the brightness change on the screen. The lights will display cool white light when the screen is dark or black. This is to create a constant bias lighting to make the watching experience eaiser on the eye.
• When the Intensity is set to the highest, the lights will brighten and dim to match the brightness change on the screen. This is to create a more vivid and dramatic watching experience.

Note: If you want to go back to the default setting, here are the default values for the Cinematic, Vibrant and Relaxation mode.
