Menu:
VGA Frequency Trim:
This menu is only available when VGA is the selected output mode (see
Primary Output
Mode
to select VGA).
This menu is used to adjust the VGA outputs’ horizontal frequency. The MVPHD-24
allows the total number of lines per frame to be increased or decreased, thus changing
the horizontal frequency while maintaining the correct refresh (frame) rate. This may
allow some VGA monitors to lock to non-standard frame rates.
The number of lines per frame, and the horizontal frequency of the VGA output are
displayed at the bottom of the menu.
Use the Knob or +/- buttons to adjust.
Menu:
VGA Frequency Status:
This menu is available when any output except VGA is the selected output mode (see
Primary Output Mode
to select output).
This is a VGA output status menu. The number of lines per frame, and the horizontal
frequency of the VGA outputs are displayed.
Menu:
Reference 1 Output:
This menu is used to configure the CBVS/REF1 Output BNC. Possible outputs include
composite video, composite sync, black burst, tri-level, TTL composite sync, TTL Vertical
Drive, and TTL Frame Drive.
When composite video is selected, and the
Primary Output Mode
is not Composite, then a low
quality secondary scaler is used to down convert any output resolutions that are higher than
standard definition. This composite output is intended to be a reference only, when producing
other non-composite output signals. For optimum composite quality, “Composite” should be
chosen for the
Primary Output Mode
.
Use the Knob (rotate) or +/- buttons to select the desired reference signal.
Once the reference signal is selected, push on the knob to enter selection.
Menu:
Reference 2 Output:
This menu is used to configure the CBVS/REF2 Output BNC. Possible outputs include
composite video, composite sync, black burst, tri-level, TTL composite sync, TTL Vertical
Drive, and TTL Frame Drive.
When composite video is selected, and the
Primary Output Mode
is not Composite, then a low
quality secondary scaler is used to down convert any output resolutions that are higher than
standard definition. This composite output is intended to be a reference only, when producing
other non-composite output signals. For optimum composite quality, “Composite” should be
chosen for the
Primary Output Mode
.
Use the Knob (rotate) or +/- buttons to select the desired reference signal.
Once the reference signal is selected, push on the knob to enter selection.
