Convergence

Color alignment on a screen is known as convergence. Colors that are aligned correctly, pixel by pixel, will produce sharp lines on the screen. If the colors do not align correctly, objects on the screen will seem to have multi-colored shadows. Poor color convergence or misconvergence, then, creates blurred images, which can cause eye strain.

You can adjust convergence by positioning the Projection Panel on an overhead projector. To adjust the convergence, follow these steps:

1.Apply power to the Projection Panel, but do not connect a video cable to it.

2.Place the Projection Panel on your projector and turn the projector on. A test pattern consisting of a series of color bars and a line grid should appear.

3.Looking at the projection screen, move the Projection Panel around on the projector until all lines, both horizontal and vertical, are solid. (As you move the Projection Panel around, you will see the lines split apart from single dark lines to rainbow-colored lines).

4.Position the Projection Panel on the spot at which the lines are the most converged.
