3 Overview
The Kramer VP-420/VP-421 PC/HD Scaler is a high-performance digital
scaler for computer graphics and HDTV signals. It up- or down-scales
computer graphics and HDTV signals to resolutions up to WUXGA and
1080p. The following output resolutions are supported:
PC: VGA, SVGA, XGA, 1280x800, SXGA, UXGA, WXGA, SXGA+,
WXGA+, WSXGA, WUXGA, COMPONENT: 480p, 576p, 720p
@50/60Hz, 1080i @50/60Hz, 1080p @50/60Hz.
The VP-420/VP-421 PC/HD Scaler also features:
•An On-Screen Display (OSD) for easy setup and adjustment, accessible
via the front-panel buttons
•A built-in ProcAmp for convenient signal adjustment
•A non-volatile memory that retains the last settings used
•Quick auto-adjust
•Freeze button
•RGBHV or component video input and/or output
The machine is fed from an external 5V DC source, making it suitable for
field operation.
Operate your VP-420/VP-421 directly via the front panel push buttons and
the on-screen display (OSD).
To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer
VP-420/VP-421 away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)

To connect your VP-420/VP-421, as illustrated in the example in Figure 3
do the following:
1. Connect a computer graphics or HDTV source to the PC/HD INPUT
15-pin HD connector.
2. Connect to the PC/HD OUTPUT 15-pin HD connector to a computer
graphics or HDTV acceptor as follows:
When connecting to an XGA acceptor (RGBHV), then connect to
the acceptor’s XGA connector
When connecting to a component acceptor (YPbPr), then connect
as shown in Table 3
