3 Overview

The VP-719xl/VP-720xl/VP-724xl is a Presentation Switcher / Scaler

designed for a wide variety of presentation and multimedia applications. It is

a true multi-standard video to RGBHV (pixel) scaler and a seamless

presentation switcher. It converts video, s-Video, component video, VGA-

through-UXGA and DVI signals to a range of user-selectable VESA and

HDTV pixel rates, as well as some other special resolutions. Using the

Presentation Switcher / Scaler, you can select any one of the inputs and scale

that input to the output at the set resolution.

The Presentation Switchers / Scalers support the following user-selectable

output pixel rates:

 VGA (640x480)  852x1024i  720x483

 SVGA (800x600)  1024x1024i  852x480

 XGA (1024x768)  1366x768  1400x1050

 SXGA (1280x1024)  1365x1024  1280x768*

 UXGA (1600x1200)

 1280x720  User Define

The VP-724xl also has the following user selectable output pixel rates: 480p,

720p, 1080i and 1080p.

Each Presentation Switcher / Scaler:

 Digitally reprocesses the signal to correct mastering errors, and regenerates the

video at a higher line and pixel rate format, providing native-resolution video for

LCD, DLP and plasma displays

 Up- and down-scales any graphics resolution to any other resolution

 Incorporates a unique graphics-scaling engine with image enhancement

algorithms, which are built into the firmware

 Is specifically designed to improve video quality by reducing chroma noise

 Scales and zooms (to up to 400% of the original size)

 Includes a built-in power amplifier of 2x5Watt RMS, ample to fill a

presentation room. Audio volume can be easily and rapidly controlled via the

front panel buttons

 Switches the audio channels in audio-follow-video mode

1 This is not a standard VESA resolution and its parameters vary from manufacturer to manufacturer. Therfore, use this

resolution with caution. It is also possible to use the parameters of this resolution in combination with the User Defined

resolution. There is also an RS-232 command for this resolution

2 Recommended for advanced users only – non-standard settings may not be recognized by the display device

3 For example, scaling a VGA input to an UXGA output, or an SXGA input to an SVGA output
