3 Overview

The VP-719xl/VP-720xl/VP-723xl/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
pixel rates:

 VGA (640x480)  1024x1024i  480p

1

 SVGA (800x600)  1366x768  720p

1

 XGA (1024x768)  1365x1024  1080i

1

 SXGA (1280x1024)  1280x720  1400x1050

 UXGA (1600x1200)

 720x483  1280x768*2

 852x1024i  852x480  User Define

3

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

4

 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 10Watts, ample to fill a presentation

room. Audio volume can be easily and rapidly controlled via the front panel
buttons

1 Available only on the VP-723xl and VP-724xl machines

2

This is not a standard VESA resolution and its parameters vary from manufacturer to manufacturer. Therefore, 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

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

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

 Switches the audio channels in audio-follow-video mode

 Includes an OSD (On-Screen Display) – for making adjustments – that can be

located anywhere on the screen, and can be doubled in size
For example, the OSD can be used to deactivate the source prompt, choose the
color of the blank screen, and choose from three seamless switching image
transition speeds

 Includes seven1 multi-functional INPUT SELECTOR buttons that can cycle

between selecting a source, freezing that source, or deactivating that source (and
displaying a blank screen), if programmed to do so2

 Includes a BLANK button, a MUTE button; a FREEZE button; a RESET TO

VGA button (to hardware-reset the output resolution); and a PANEL LOCK
button

 Has two HD15F outputs, that can be used as graphics, or HDTV3 outputs

 Incorporates full ProcAmp4 for video correction and enhancement

 Offers high quality de-interlacing 3:2/2:2 pulldown5

 Can provide non-linear scaling for 4:3, 16:9 transformation6

 Supports firmware upgrade via RS-232

 Includes non-volatile memory that retains the last setting, after switching the

power off and then on again

 Includes a built-in Picture-in-Picture (PIP) inserter (not available on the VP-719xl)

Control your Presentation Switcher / Scaler:

 From the front panel buttons

 Remotely from the infra-red remote control transmitter

 Remotely via RS-232

Achieving the best performance means:

 Connecting only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)

 Avoiding interference from neighboring electrical appliances and positioning the

Presentation Switcher/Scaler away from moisture, excessive sunlight and dust
