Chapter 4—Setup Adjustments

If the projector uses more than one (1) type of VIC, the type can be determined by accessing the SYSTEM-MAINTENANCEmenu and selecting STATUS LIST. Each VIC slot will be displayed with the type of VIC in each slot. Complete the Timing section first, Geometry next, and Convergence last.

They are performed in this order because Geometry depends on proper Timing settings and Convergence depends on correct Geometry.

Ensure that the projector is installed and positioned correctly at the outset so that all later adjustments will be at their optimal levels and the image will be the sharpest possible. Positioning the projector is the most important step in the setup procedures. The projector-to-screen alignment should be as square as possible before starting setup procedures in order to accomplish Timing, Geometric, and Convergence adjustments properly.

Prior to starting the procedures, a channel and source (source file) must be selected for the setup adjustments. This is covered in Section 4.1.2 on page 4-6. A rough focus of the projection lens may be necessary to be able to read the menus.

4.1.1.Projection Lens Focus (Rough)

For the Timing and Geometry setup procedures below, it is necessary to obtain a rough focus of the Projection Lens in order to read menus and do the adjustments. If the focus is adequate to read the menus, this procedure can be skipped until after the Timing and Geometry adjustments are finished. When the Timing and Geometry adjustments are complete, and prior to starting convergence, the Projection Lens focus adjustment should be repeated and a sharp focus obtained.

To obtain a Rough Focus of the Projection Lens:

1.Press MENU to display the MAIN MENU on the screen.

If necessary, use the ESCAPE key to back out to the MAIN MENU.

2.Select SYSTEM from the MAIN MENU.

3.Select TEST PATTERN from the SYSTEM menu.

4.Select FOCUS from the TEST PATTERN menu.

NOTE: The H pattern is preferred for focusing the Projection Lens.

5.Select PROJECTION LENS from the SYSTEM menu.

6.A small window displaying FOCUS and ZOOM arrows appears on the screen.

7.Use the up/down arrow keys to zoom the image to the desired size. The raster and image should be smaller than the screen. Ensure the FOCUS ENABLE box in the PREFERENCES menu is checked.

8.Use the right/left arrow keys to get a rough overall focus to be able to read menus. A sharper focus will be obtained later after the Geometry procedures are completed.

9.Press ENTER to complete this adjustment.

10.Press ESCAPE twice to display the MAIN MENU.
