I can't find an answer to this anywhere. Will a light colored desktop wallpaper burnt out my monitor quicker than a dark colored wallpaper? I set my monitor to shut off after 10min of non use. But I would just like to know if a light color wallpaper makes a dif vs. a dark color. I know the power usage increases with dark colors. But very minimally. But I would assume the backlight would burn out quicker with lighter colors? So, conclusion, does it matter??
