12 VP-790 Blending Images - Setting the 4-Corner Warp

Figure 11: The 4-corner Menu

3. Select a corner, for example Top Left

The following window appears:

Figure 12: Adjusting the Location of the Top Left Corner

The Diagonal Projection menu allows you to adjust the position of the X and Y co-

ordinates of the corners of the projected image.

4. Align the test pattern on the screen by selecting each co-ordinate in turn and

moving the corner of the projected image.

5. Continue this process until the cross hatch pattern fits the screen and the

central area of overlapping pattern is accurately superimposed and the

pattern in this area is white.

Note that in ‘4 Corner’ warp alignment the screen must be flat and

rectangular. This is important as linearity is automatically maintained

between the corners and accurate alignment in the central area is

only possible when the shape produced is a rectangle.

You can check if your alignment is correct by changing both processor test patterns

to the ‘Aspect Test’ pattern
