About to put the Panny 6 on the wall tomorrow and want to get some ideas of the height it should be.... Read somewhere it is a good idea to have the screen at a "standing height" - does that mean your eyes are in the middle of the screen when you are standing up? I am 6`2 and that would seem way too high. Will be seated about 8 feet away on sofas. Any thouhgts very welcome. Many thanks.
