HDMI preview output refresh rate
To set the refresh rate for the local HDMI preview output:
1. Open the Input/Output Settings page.
2. Expand the Preview Output Configuration panel.
3. Select the output refresh rate (either 50 Hz or 60 Hz) from the Refresh Rate
drop-down list in the
Preview Output Configuration
NOTE: The resolution of the local (preview) output follows (is based on) the archive
encoding resolution.
Input switching OSD duration
When a new input is selected for either channel, the SMP 351 can briefly display the names
of the active inputs on-screen. The input switching on-screen display (OSD) is a small
message box displayed on top of the source video content. It appears in the upper left of
the screen and includes text such as "Input 1 active" on the first line and "Input 3 active" on
the second line, depending on which inputs are currently selected.
The length of time to show the input switching on-screen display (OSD) can be set as
follows:
1. Open the Input/Output Settings page.
2. Expand the OSD Configuration panel and look in the Input Switching OSD
panel.
3. Enter the desired number of seconds into the How many seconds should Input
Switch OSD be displayed? field or click the Up and Down arrows to adjust the
value.
Outputting and using a video test pattern
NOTE: No input signal is needed when using a test pattern for display device setup.
The Input/Output Settings page allows selection and immediate output of one of
eight internally stored test patterns to the local HDMI preview and recording output, and
the 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:
1. Open the Input/Output Settings page.
2. Expand the OSD Configuration panel.
3. Select a pattern from the Test Patterns drop-down list. A preview of the test pattern
appears above the drop-down list. Available test patterns include the following:
Color Bars Time Stamp
Aspect Ratio 1.33:1 Aspect Ratio 1.78:1
panel.
Pulse Crop
Aspect Ratio 1.85:1 Universal OSD
