Step 1 – If the text is blurred and the text color persists (smears) into the blank

space after the text, this is "black streaking" and you need to increase the

peaking value. If you see white bands persisting after the text or you see small

white areas after the text, you have "white streaking" and you need to decrease

the peaking value.

Black and White Streaking

Step 2 – If you see "blooming" or pixel areas that appear larger than normal, you

need to decrease the boost.

Step 3 – The QM skew bitmap consists of two sets of three vertical lines of red,

green and blue positioned directly over one another. The amount of skew is

determined by observing which line is shifted farthest to the right. The line

farthest to the right has the most skew delay. Adjust the other two lines by

increasing their skew so that they all line up. In the following example, increase

red and blue to match green.

Step 4 – The crosshatch test pattern is displayed. Re-check your adjustments.

Lines should appear crisp and all white. If there are color outlines, return to the

skew adjustment. If they are smeared, perform peak and boost again. If they are

unstable, check for induced noise.

• If you see any color outlines, return to the skew adjustment.

• If the lines appear smeared, return to the peaking and boost

adjustments.

• If the lines are unstable and exhibit some crawl, check the system for

induced noise.

NOTE: An image that is not horizontally or vertically centered indicates that an

adjustment of the monitor or projector is needed, and is not a problem with the

Crestron QM system.

NOTE: All presets are immediately stored to the QM-RMCRX-BA, even those

on other screens. There is no need to explicitly save them.

NOTE: You may also use the browse button to load third-party video test

patterns (if installed).

For additional details, download SystemBuilder from the Crestron website and

examine the extensive help file.

Setting Network IDs in SystemBuilder

SystemBuilder provides several convenient methods of selecting and assigning

after completing the program. The following procedure permits you to change

and reassign device Net IDs after completing the program.

1. After completing your SystemBuilder program, click the Build and

Upload button

2. Ensure that all network devices are connected to the control system.
