Yamaha DPX-1200 manual Projection image position, Keystone adjustment

Projection image position

Follow the instructions to adjust the position of the projected image on screen.

<Using ZOOM to adjust image position>

This illustration shows the limits within which the zoom function can alter projection distance [a] in relation to screen size. You can adjust the image within these limits so that it fills the screen completely. ( ☞ page 21)

<Using V.POS (vertical position) to adjust image position>

You can adjust the vertical position of the projection image up or down by half of the height of the screen. For example, shifting V.POS fully up brings the lower limit of the image above the centerline of the lens. (☞ page 20)

If you mount this unit on a tabletop, you can use the adjusters on its underside to change the position of the projection image. Rotate the movable part of the two screw-type adjusters at the front bottom of the case to adjust the height. The movement range of the adjusters is 3 cm (1-1/4 inch). Adjust with care as loosening them further than 3 cm may cause them to separate from the unit.

◆Keystone adjustment

If you mount the unit at an angle to the screen, it projects trapezoidally distorted images. You can use the [keystone Correction] item in the [Setup] menu group to rectify this. (☞ page 22-34)

Memo

•If the keystone is adjusted aspect ratio may not be correctly maintained. To correctly maintain the aspect ratio, try to use the DPX- 1200 with the lens shift in the center position.

•The video may be disturbed by keystone correction. Wherever possible, we recommend setting up so the screen and projector form a right angle.
