Hi laurent 14. I have looked at my menu pop up and it says, from left to right, e, AUTO, page of typing, loudspeaker, input. I can't send a photo of it as I don't have a camera but I'm sure you will recognise this pop up screen from my description. Will this help you tell me how to adjust contrast?
