KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
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 (640x480), SVGA (800x600), XGA (1024x768), 1280x800,
SXGA (1280x1024), WXGA (1366x768), SXGA+ (1400x1050),
WXGA+ (1440x900), WSXGA (1680x1050), WUXGA (1920x1200)
HDTV: 480p, 480i, 576p, 576i, 720p @50/60Hz, 1080p @50/60Hz, 1080i
@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 IR remote control and 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 to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
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

5 Connecting the VP-420/VP-421 PC/HD Scaler
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
Table 3: 15-pin HD PINOUT for HD
PIN # Signal
1 Pr
2 Y
3 Pb

3. If connecting a VP-421, connect the DVI OUTPUT to a DVI acceptor1.
4. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 3).
1 The VP-421 outputs on both the 15-pin HD connector and the DVI connector. You can connect to either output or to both of
them simultaneously

Pressing +/FREEZE freezes the display, the next press unfreezes the
display
Pressing – /AUTO ADJUST automatically centers the display
Pressing MENU and –/AUTO ADJUST together resets the display to
720p and the COMPONENT OUT LED lights
Pressing +/FREEZE and ENTER together resets the display to XGA
and the COMPONENT OUT LED turns off

6.2 Using the OSD
You can use the OSD to set a wide variety of parameters. When the MENU
button is pressed, the main menu opens allowing access to all the device
settings (see Table 4).
When setting FINETUNE, COLOR, SIZE, OUTPUT (see Table 5), and
OSD (see Table 6) a submenu opens with the applicable parameters.
6.2.1 Using the Front Panel Buttons
While the OSD is open, the front panel buttons perform the following
functions:
Pressing + and – move forward and backward through the menu items
and increment or decrement the parameter values
Pressing ENTER selects and activates a menu item or accepts the
parameter value set
Pressing MENU closes the OSD menu1
As an example of setting parameters, to increase the contrast on the display:
1. From normal operation, press MENU.
The OSD main menu appears on the screen.
