, this field displays the resolution
of the decoded stream. If an exact match is not possible, then this field displays
Special
followed by the available resolution closest to the decoded stream.

Output Format (VN‑Matrix 200/225 only)
— This drop-down lists contain preset
output video formats, plus an additional
auto
option. Selecting a preset format forces
the output of the VN-Matrix device to the selected format. Selecting
auto
matches the
output video format to the native resolution of the decoded stream.
NOTE:
When a preset output format is selected, the
Scale
to
Output
Format
check box
must be selected
.

Scale to Output Format (VN‑Matrix 200/225 only)
— When selected, this check
box enables scaling of the decoded stream to the resolution selected in the
Output
Format
drop-down list. Upscaling and downscaling are supported.
NOTES:
•
For smooth playback, select an output format with approximately the same
frame rate as the source.
•
Scaling adds two frames of latency to the delay between source capture and
display output.
•
Scaling is disabled when
auto
is selected in the
Output
Format
drop-down list or when the scaling ratio is 1:1.
