I do not see this being talked about. But how do you decide which is the correct backlight for your LCD models? I have a Samsung UA55H7150. For calman and Lightspace, for the probe like i1 display pro, you can select LCD - White, LCD CCFL, LCD many others. It used to be easy for plasma as there was only one. But with such a wide range of different LED backlighting incorporated in LCD makes it difficult to know which to choose. Or does it not matter so much?
