Configure frame size
By default, for channels with only one layout and when that layout has only one video source, your
Networked VGA Grid automatically uses the incoming source frame size as the stream frame size. Frame size
greatly affects the amount of bandwidth needed to transmit your stream. The larger the frame size, the more
bandwidth you need to stream it. So you may want to keep the frame size the same as your source, or you
may want to apply upscaling, downscaling, stretching, or black bar framing, depending on your needs.
For example:
l
if the input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l
and stream frame size is set to another 16:9 frame size such as 1280×720,
the smaller stream frame size causes the system to downscale the image and use less bandwidth to
transmit.
Or if you have a widescreen/HD format source but need a 4:3 output frame size, you can add black bars to
the top and bottom of the frame.
The system is designed to provide scaling, however for the best overall system performance
(particualrly when reaching maximum system capacity), configure your source to provide the
correct frame size and avoid scaling.
To configure your stream's frame size complete these steps in the VGA Grid's Admin panel:
1. Login to the Admin panel as

.
2. Click

for the your channel; the encoding configuration page opens.
3. Scroll to the

4. Perform one of the following steps:
Using current signal resolution as the frame size only works for channel layouts with a
single source. If you're using multiple sources, follow the steps below to set your frame
size.
a. Check the
