*Native DVI output resolution

✝The output refresh rate is auto-selected, based on the video refresh rate of input 1.

NOTES:

•For output resolutions with less than 1024 pixels horizontally, the optional DVI output is limited to a true horizontal resolution of1024 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 DVI output card’s actual resolution is 1024 × 480.

•For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI output is limited to a true horizontal resolution of 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 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; the DVI output fully supports the selected horizontal and vertical resolution. The DVI output resolution for these rates exactly matches the analog resolution.
