Model 880 Series Quick Start Guide 15
Selecting formats manually
When testing a display that is not EDID-compliant, you must manually choose formats
that are supported by the display. Note that once you select an interface the source list
of formats will be filtered to only those that are suitable for a particular video interface.
For example if you select CVBS as the interface the source list of formats will not
include the VESA formats.
The generator has a library of standard formats. For a description of how the library is
organized, see the 881/882 User's Guide.
Once you have selected a format you can modify the format options and settings if
necessary. For instructions on this refer to the User's Guide.
To select a format:
1. Identify the type of display (composite television, component standard definition
television, component high definition television, computer equipment, or other
specialty display).
Check the specifications of your display for supported formats.
2. Press the Source key to access the list of formats. A list of formats appear on the
generator’s display as shown below. To see all of the formats, press the + and -
keys.
The list of formats that appears when you press the Source key may be a filtered or
abbreviated list. Formats not suitable for the selected interface type will not appear
by default on the Source list.
The list of formats that appear when you press the Source key will be the formats in
the Format folder of the media storage location that you have set the format path
parameter to using either the Browse mode or command line (FMTP parameter).
4. Choose a format by pressing the adjacent soft key.
Selecting images
Once you have determined the format or formats appropriate for testing the display, you
will apply a series of images suitable for evaluating the display. Of primary importance
is determining what type of display you are testing (for example, CRT or digital flat panel
display). You must also determine if you are testing composite TV and use images
appropriate for these formats and video types.
Each image in the generator’s library is intended to test one or more attributes of a
particular display type and video type.
