a complete presentation system, replacing slides, projectors, and overhead
projectors. Use the TV or VCR sound, or connect to a public-address sound
system for large audience presentations.

VGA to Video Portable Plus
The VGA to Video Portable Plus (Figure 1) has one input connector and
three output connectors. VGA IN connects with the VGA output of a PC or
notebook computer. VGA OUT connects to a VGA monitor. There are three
video outputs: Video, S-Video, and RGB Video.
The VGA to Video Portable Plus has two switches. One selects either the
NTSC or the PAL broadcast system. The other changes the field rate to
50 or 60 Hz. (See Section 5.3 for more information.)
