processes one or two signals. These can be sources of multiple types: composite video or
S-Video, analog or digital RGB sources or component video.
The most common VESA timings and HDTV timings are stored as presets for RGB sources and HDTV signals. In
addition, user defined timings can be saved. The timing and aspect ratio of the connected signal is detected
automatically.
The card provides two input modes: Dual input mode to display two signals simultaneously and single input
mode for specially demanding sources. The mode is automatically switched depending on the signal that is ap-
plied at

. In single input mode the second input is not available.

static frame rate reduction for Dual DVI Input Card
The video software allows selecting additionally a dynamic frame rate reduction of the source, which must be
multiplied by the static frame rate reduction to obtain the overall frame rate reduction.

digitizes one or two analog monitor signals. It supports two monitor signals with a pixel
frequency between 10 MHz and 135 MHz. The most common VESA timings are stored as presets. In addition, user
defined timings can be saved. The timing and aspect ratio of the connected RGB signal are detected automati-
cally.
