This document explains how to display videos from GV-1120B, GV-1240B and GV-1480B on TV monitors. There are several ways to perform TV Out functions on GV-Combo B Cards:
- Using the Digital Matrix function on GV-DVR / NVR
- Using GV-Multi Quad Card
- Using GV-Loop Through Card
- Using third-party PC to TV converters
- Using the built-in TV out port on the graphics card
GeoVision’s free software Digital Matrix allows you to display videos from GV-Combo B Cards on up to 8 monitor displays. Most graphics cards now support dual monitors. To display multiple monitors, additional graphic cards may be required.
You will need to use Windows Display Properties to activate multiple monitors and then configure the Digital Matrix settings on GV-DVR / NVR. Below is an example using Windows XP.
