hi can someone help me? the image the projector creates is a bit off center and the bottom and the right side of the image is cutt off. like i can only see half of my start button when i use hdmi. is this normal? and is there anyway to fix it without the keystone stuff? i can see faint grey area in the top and left side, that if i can center the image a bit more will fix this weird cutt off issue but i have no idea how to do it.
