3.2 Adjusting Each Margay To Its Source

3.2 Adjusting Each Margay To Its Source

The source picture—from computer, video, DVD—is not always perfect in its size or strength; it does not always conform exactly to a standard. Margay has a way to compensate for this.

Computer sources vary quite a bit from computer to computer. They even vary between video outputs on the same video card. Video sources vary more.

To make the Margay respond correctly to these non-standard sources we adjust Input Levels.

•Input Levels for computer sources, analog, see page 44

•Input Levels for computer sources, digital, see page 48

•Input Levels for video sources, page 50

How does Input Level relate to Color Balance

To make all the displays show the same color and brightness across the whole wall, you need to adjust input levels and do color balancing.

You can do Input Levels first, or you can do Color Balance first. It doesn’t matter. But they must both be done.

Input Levels and Color Balance do not affect each other, but they both affect the final picture.

• Color Balancing the displays, page 52

Displays differ from one another because of very small differences in the color of the light produced by the lamp and by differences in the dyes used to make the color in a DLP™ optical engine.

In color balancing you use the display’s internal test patterns of white, first, then gray. The internal pattern assures that a pure white is used.

Selecting the source

1.Press MENU on the remote.

2.Select PICTURE and press ENTER.

3.Select SOURCE and press the lEFT ARROW key.

4.Choose the source you want and press ENTER.

5.Press MENU again to close all menus.

What does Input Level do?

For analog computer sources adjusting to the com- puter’s picture output means finding what that com- puter means by black and white.

Black is supposed to be a voltage of zero coming from the computer’s video card, but it almost never is. White is supposed to be a voltage of 0.7 volts, but it usually isn’t either.

The Input Level adjustment process asks you to provide a picture from the computer that is black, then one that is pure white. With these, you can quickly and automatically make the display “learn” what this computer means by black and white.

The result? Good pictures, using all the dynamic range of color coming from the computer.

For Input Levels, you must use black and white coming from the computer you will use for the program. You don’t make this adjustment with your work laptop and then switch to another computer for the display’s program of pictures.

What does Color Balance do?

Color balancing adjusts all the displays in a wall so they produce the same colors across the entire wall.
