5.7.1 Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-460 offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.
FOLLOW INPUT – The aspect ratio and resolution of the
input video or graphics signal are both preserved (no
scaling). For example, a composite video image with a 4:3
aspect ratio will appear with the same aspect ratio on a
1080p (16:9) output image, surrounded by black bars
FOLLOW OUTPUT – The aspect ratio and resolution
of the input signal is re-sized to precisely match the
aspect ratio and resolution of the VP-460 output
signal. This may result in some distortion to the input
signal images
BEST FIT – This setting re-sizes the video or
graphics input signal to “best fit” the output resolution
while maintaining the aspect ratio of the input signal.
For example, a composite video signal (4:3 aspect
ratio) will “best fit” to the top and bottom of a
widescreen output image, resulting in black pillars on
either side.
LETTERBOX – This setting compresses the top and
bottom edges of the input signal, but fills the width of
the screen.
5.7.2 Master Connection Settings
The Master Connection (HDMI or SDI) is usually set to the main output display so
that the optimal resolution for that display can be obtained. By setting the output
resolution to Native, the
VP-460 is triggered to read the EDID of the main display
and change the output resolution value according to the native resolution of the
display.
Note that when the output resolution is set to Native:
• Selecting SDI as the Master Connection results in an output resolution of
720p @60
• If SDI is selected as the Master Connection, hot plugging the HDMI output
will not change the output resolution
• If HDMI is selected as the Master Connection, and a new display is
connected to the Master Connection output (hot plug), the
VP-460
