*Native DVI output resolution

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

• 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 DVI output card’s actual resolution 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 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.

Sync Type and Polarity submenu

Select the output whose sync type and polarity you want to set by pressing the desired Output button.

Rotate the Adjust knob while in this submenu to select the output video type (RGBHV or RGBS) for the selected output.
