* one time screen does crop at 6.5 left and right, changing the screen vertical position using menu does translate the image cropping left and right at fix position : 6.5 centimeters fix black border. About extra 1 centimeter pixels : image in middle of image does move, but not the borders at all.
* a second time image does move perfectly (completely/totally) left and right without crop, and if centered has 6.5 black border left and right. This time image seems complete but crushed.
