Dear, I've faced another problem here. A viewsonic E70 can't adjust the horizontal size and there's pinchusion on the screen and it can't adjust pinchusion also. Any clue on this? Please advise. Thanks in advance and great day to you all.

Is the picture too wide or narrow.

Sorry for didn't state it clear. The problem is it can't adjust the horizontal size and the horizontal remain same even I've adjust it. It's not too wide, have almost more than 1 inch for left and right. Please advise. Thanks in advance.
