Different color setting will be memorized at 4 different source 
groups. But they will be same under same source. 
DVI/VGA
Component-p (480p/576p/720p/1080i)
Component-i (480i/576i)
Video / S-Video
When we adjust color setting the current color temperature will be 
memorized before it auto switch to “User”. Because the memorized 
color temperature will be a base of “User”. For example:
1.) Colour temp. is Mid
2.) User creates his favorite color based on “Mid” setting of colour 
temperature. So when user switches colour temperature to “User”, 
will fi  nd the image color temperature close to 
“Mid”.
