Can anybody help me with some display problems i have been having with my Z2.Have had the projector for about 6 months which i used in my living room but was never allowed to put on the wall by my darling wife.Anytime i tried to use the projector had to put it to the right hand side of my couch,so obviously was not sitting in the middle of the room. Have now moved the projector to my spare room but cannot seem to get the picture exactly straight. If i move it around can get the screen horizontally in a straight line but vertically the screen is a bit diagonal. Or vice versa if get the vertical side of the screen straight horizontally the screen is diagonal. Is there anyway i can "reset" the projector back to bog standard or have my months in the living room messed it up.
