an HDMI or DVI output, like your DVD player, Satellite Box, HD DVR, Set Top Box, or even
your PC, to any display with an HDMI or DVI input.
Page 7 of 24
HDMI 4x1TMOperating Instructions
4 Inputs to 1 Output HDMI Switcher:
Let's start with the basic functions of your Key Digital
®
HDMI 4x1TMSwitcher. First and foremost, you purchased the product as a four (4) input to one (1) output switcher, capable of
supporting the 19-pin HDMI Type A connections with HDCP (Copy Protection).
Your Key Digital®HDMI 4x1TMSwitcher carries whatever signals are present on your HDMI cables. That means that you can switch Video as
well as Audio. HDMI lets source devices (like your DVD player, Satellite /
Set Top Box, or PC) “talk” with your display or “sink” device, and your
HDMI 4x1
TM
Switcher functions as a true HDMI repeater to pass along
this information. Your switching connection is truly seamless!
Versatile video and audio Inputs and Outputs:
Next, let's look at the versatility offered by your HDMI 4x1
TM
Switcher. Flexible Audio I/O
interfaces include HDMI, Toslink Optical audio, digital PCM audio, and analog Left & Right
stereo audio. If you have a DVI device you want to switch, or a display with a DVI input,
simply use HDMI<>DVI adapter cable(s).
A built-in Scaler to perfectly match the native resolution of your display:
All of the above features are what you've come to expect from Key Digital
®
. In fact, you can
stop right here, and you would have the perfect solution for all your HDMI switching requirements. But your HDMI 4x1TMSwitcher offers so much more…
Wouldn't you like to get the most your HDMI interface has to offer? Sure, HDMI is a pristine,
digital A/V interface. But how do you best interface your 480 sources to the native resolution of your display? Or what if the HD output from your Satellite / Set Top Box doesn't
match the native resolution of your display? Or what if you want to connect your PC to a
projector? This is where the beauty of your Key Digital
®
HDMI 4x1TMSwitcher shines
through. With world-renowned Key Digital®Clear Matrix ProTMtechnology built right into your
HDMI 4x1
TM
Switcher, any selected input video can be scaled exactly to match the native
resolution of your display. Most of the popular source and display formats and resolutions
are supported.
A built-in Video Processor:
But the power of your HDMI 4x1
TM
Switcher does not end there. An easy-to-operate, fullfunction, high-quality Video Processor is built into your switcher. For each input, you can
control a broad range of functions, from Brightness and Contrast, to Size, Position, and even
“Zoom” - Aspect Ratio adjustments. Test patterns built-into your HDMI 4x1
TM
Switcher help
you set-up your video system.
So easy to Control:
With so many features and versatility, you may be wondering: Is the HDMI 4x1
TM
Switcher
easy to operate and control? Simply use the convenient front-panel display and pushbuttons, the IR Remote Control, or RS-232 to easily control all features of the product.

Firmware Upgrades
From time-to-time, Key Digital®provides the option for you to update the Firmware that operates and controls your HDMI 4x1TMSwitcher, such as to add a new or impr
oved feature.
These updates are optional, and you should only perform upgrades as provided and
instructed by Key Digital
®
. Check our web site at www.keydigital.com for the latest firmware
updates.
Should a Firmware Upgrade be available that you are interested in installing in your unit,
please be sure to carefully and completely follow all of the steps described below.
1.
H Zoom (Horizontal Zoom): This “H Zoom” feature is particularly useful for some
Plasma owners, who may want to stretch the image to fill the screen and avoid the
nasty burn-in. If the input signal is a Pillarbox, Horizontal Zoom extends (distorts)
the image from left to right to fill the screen. For example, when a 4:3 movie is upconverted to HDTV in a studio, it may be simply released in the Pillarbox format,
with black bars to the left and right of the image in a 16:9 window.
2.
V Zoom (Vertical Zoom): This “V Zoom” feature is particularly useful for some
Plasma owners, who may want to stretch the image to fill the screen and avoid the
nasty burn-in. If the input signal is a Letterbox, Vertical Zoom extends (distorts) the
image from top to bottom to fill the screen. For example, it is very common for a
widescreen DVD movie to be presented in Letterbox, because the original movie
may be captured in 2.35:1 Cinemascope or some other Aspect Ratio that creates a
small letterbox in a 16:9 window.
3.
HV Zoom: This mode simultaneously stretches the image uniformly in both the
Horizontal and Vertical directions, using the same ratios as in H Zoom and V Zoom.
This Zoom mode may be preferred over the H- or V-Zoom, both of which geometrically distort the image. Because the image is “Zoomed,” there will be a slight loss
(cropping) of the image at the top and bottom for Pillarbox sources, and at the left
and right for Letterbox sources.
