Full Screen Renderer Filter
The Full Screen Renderer filter uses Microsoft® DirectDraw® to render full-screen
video on older graphics cards that can not quickly stretch a 320x240 video to 1024x768. To overcome this hardware
limitation, the Full Screen Renderer simply switches the
graphics display card into 320x240 mode. Newer video cards can stretch the display quickly enough to permit
the Video Renderer filter to be used for both windowed and full-screen modes.
The Filter Graph Manager calls the Full Screen Renderer into a graph automatically. The newer the video card, the less likely it is that this filter
will be used. Do not manually add this filter to a graph; let the filter graph manager
select the video renderer.
