Output resolution, rate, sync format, and polarity
The ISS 408 scales the input input up or down to any a number of output
resolutions and rates. The switcher outputs the scaled video, as RGBHV or RGBS,
with user-selectable polarity, via either the program or preview connectors. The
table below shows the resolutions and rates available on the ISS 408.

For output resolutions with less than 1024 pixels horizontally, the
optional DVI program output's true horizontal resolution is limited to
1024 pixels. The vertical resolution is the selected vertical resolution. For
these resolutions, the ISS DVI output is 1024 x {selected vertical size}.
For example, if the output resolution is set to 640 x 480, the DVI output
card's actual resolution is 1024 × 480.
•
For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional
DVI program output's true horizontal resolution is limited to 1280 pixels.
For these resolutions, the ISS DVI output is 1280 x {selected vertical
size}. For example, if the output resolution is set to 1080p, the DVI output
card's actual resolution is 1280 x 1080.
•
The DVI card outputs all other selected resolutions normally.
•
Resolutions marked with an asterisk (*) in the table above are native DVI
outputs, meaning that the DVI output fully supports the selected
horizontal and vertical resolution. The DVI output resolution for these
rates exactly matches the analog resolution.
