When I use F1 asking for contrast. The response is always about the brightness (and contrast). Although if one follows the "instruction" there is in fact NOTHING about contrast-it gives directive for brightness-which in this case is of no help.

Please advise the true source to 'alter the contrast control' on the user end?
