The VideoPreviewWindow keyword is used when using a Miranda DVI-Ramp device. It locates a preview device that has a matching size and refresh rate in the VideoPreviewDevice list specified in the init.cfg configuration file. When you start the application or switch to another project from the application, the graphics-to-video display is mapped to the appropriate device according to the width, height, and refresh rate specified with this keyword.
|<xsize>, <ysize>||The horizontal and vertical size of the area of the image window output to the graphics-to-video display.|
|<refresh_rate>||The refresh rate of the output.|
