2 EGA | Black Box AC401A, AC400A instruction

CHAPTER 4: Operation

If the colors still need adjustment, follow these steps and use the red and green adjustments to fine-tune the panel:

1.Move the green bar down until you have a rich red and a solid black.

2.Move the red bar down until you have a rich, true green. If cyan turns green, the green bar turns brown, and the white turns magenta, you have moved the bar too far down.

3.If your white is magenta-tinted, drop the red bar down a few steps until it is white, but not so far that the black turns red. White and black, however, are always going to be slightly reddish.

4.7.2 EGA 64

For the True Color Panel, EGA 64 may affect the color brown on some EGA systems and some VGA systems when in EGA mode. If your brown is displaying as light red, turn on the EGA 64 setting.

For the Monochrome Panel, EGA 64 may allow you to get all 16 shades of grey instead of 15 shades.

Default value is OFF.

4.7.3TRACKING

The Tracking adjustment bar allows you to match the Projection Panel’s internal clock to the different computer graphics signals. Using tracking allows the Projection Panel to project crisp images from a range of computer graphics systems. There are 64 tracking levels.

You need to adjust the tracking if the display shows evenly spaced, fuzzy vertical lines, or if the projected image is too wide or too narrow for the screen.

Move the tracking bar down (lower numbers) to make the image look narrower. Move the tracking bar up (higher numbers) to make the image look wider. The default Track value is shown with the Video Information. As you move the Tracking adjustment bar up or down, the Track value changes. Move the Tracking adjustment bar up or down until the fuzzy lines move apart on the screen or disappear, or the text fits the screen. The ideal is to have no bars visible and all the projected text or graphics on the screen.
