Output Resolution, Rate, Sync Format, and Polarity
The ISM 482 scales the input signal up or down to any of a number of output resolutions and rates. The switcher outputs the scaled video as RGBHV or RGBS, with

NOTES:
•For output resolutions with less than 1024 pixels horizontally, the optional DVI output’s true horizontal resolution is limited to 1024 pixels. The vertical resolution is the selected vertical resolution. For these resolutions, the ISM DVI output is 1024 x {selected vertical size}. For example, if the output resolution is set to 640 x 480, the actual resolution of the DVI output card is 1024 × 480.
•For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI output’s true horizontal resolution is limited to 1280 pixels. For these resolutions, the ISM DVI output is 1280 x {selected vertical size}. For example, if the output resolution is set to 1080p, the actual resolution of the DVI output card 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.
