What is TOC (Touch of Color)?
Samsung's Touch of Color design embeds red colored accents in the bezel of some LCD monitors for a stylish, unique new look. The TOC design is purely cosmetic. Touch of Color is simply a cosmetic design feature, not a light, function or setting. Touch of Color cannot be turned on, enabled or adjusted, since it is not an electronic feature.
The red color is embedded in the plastic of the bezel. It is not a light, and you can not adjust the color.
