Outputting and using a video test pattern
NOTE: No input signal is needed when using a test pattern for display device setup.
The OSD Configuration panel in the Input/Output Settings page allows selection and
immediate output of one of eight internally stored test patterns to the local HDMI preview
output from the SMP, as well as to the recording and output stream. Video test patterns
are helpful for calibrating connected displays or projectors for color, convergence, focus,
resolution, contrast, and aspect ratio. Audio test options are useful for testing audio output.
To select and output a test pattern:
Open the Input/Output Settings page.
1.
2.
Expand the OSD Configuration panel.
3. Select a pattern from the Test Patterns drop-down list. A preview of the test pattern
shows above the drop-down list. Available test patterns include the following:

Figure 55. Test Patterns
• The Pulse "test pattern" is an audio-only test. Select Pulse to output an audio
pulse of 400 Hz at -10 dBu for audio output testing.
• For composite mode only:
The Time Stamp pattern displays white text in a small, gray rectangle with the
•
unit date and time (for example: Fri Apr 18 HH:MM:SS) on a black background
in the top left corner of the display window.
• The Universal OSD pattern consists of a small, translucent, gray rectangle
with white text overlaid atop the source video content. It shows in the upper left
of the screen. The text includes brief custom text followed by three selectable
elements separated by commas. The options for those elements are listed in
Setting up the universal OSD test pattern
The universal OSD pattern can be displayed together with the main AV content
because it overlays the video rather than replacing it. As a result, the universal
OSD pattern can be used at any time, not just during setup. It can also serve as
an on screen label for presentations, in addition to metadata labels (which may
or may not be displayed, depending on the screen layout) (see
Layout
on page 81 for more information on metadata within screen layouts
and on selecting content for the metadata fields).
The selected test pattern is immediately output to the display and reflected in the preview
in the AV Controls panel on the left of the screen. The test pattern displays until another
pattern, or Off is selected from the Test Pattern drop-down list, or until unit power is
recycled.
NOTE: When a test pattern is selected, it is overlaid atop the source AV and streamed
to the display, stream, and recording. If Off is selected, the test pattern is turned off.
