5 Using Your 840HDMI HDMI Pattern Generator

This section describes how to:

 Connect the 840HDMI HDMI Pattern Generator (see section 5.1)

 Operate the 840HDMI HDMI Pattern Generator (see section 5.2)

 Interpret each Pattern Number Definition (see section 5.3)

5.1 Connecting Your 840HDMI HDMI Pattern Generator

To connect the 840HDMI HDMI Pattern Generator, do the following1:

1. Connect the OUTPUT connector to an HDMI acceptor, for example, a
flat panel LCD display (as Figure 4 illustrates), or a projector or plasma
screen.

2. Connect the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity.

Figure 4: Connecting the 840HDMI HDMI Pattern Generator

5.2 Operating Your 840HDMI HDMI Pattern Generator

Several patterns (see Table 3) are programmed into the 840HDMI HDMI
Pattern Generator, in order to assess various aspects in the flat panel LCD

display, projector, Plasma screen or cable. For example, the 840HDMI tests a:

 Flat panel LCD display1 by testing if all the pixels illuminate with

the correct amounts of light, linearity, and high frequency response

 Projector, verifying that the colors are as required, tuning the size

and focus of the picture

 HDMI cable, checking the quality2 of the colors, both separately and

together

 Plasma screen, to check the black level of the plasma monitor (use

PATTERN 00 to generate the black screen)

To operate the 840HDMI HDMI Pattern Generator, do the following:

1. Press the appropriate PATTERN button (PATTERN + to display the next
pattern or PATTERN – to display the previous pattern) to generate the
required pattern. The PATTERN NUMBER 7-segment Display shows the
selected pattern number.

2. Observe the output on your flat panel LCD display, projector or plasma
screen.

1 Which is built on a matrix of pixels, each pixel consisting of three components: R, G and B
2 For example, a fuzzy red color in the picture indicates a problem with the red wire
