Scheimpflug Adjustment (Diagonal image focusing)

With the diagonal image focusing corrections, it is possible to obtain uniform focus for the total projected image.

These corrections must be repeated for each colour. The Diagonal image focusing is repeated 3 times, first for green, then for red and then for blue.

First, be sure that the CRT projection angle is correctly adjusted, otherwise it is not possible to obtain proper overall focus of the image.

Press ENTER to start the green adjustment.

Press EXIT to return to CRT Projection Angle Adjustment.
