Example of HDMI™ to DVI Cable
Y Pb Pr:
This is also known as Component Video input (analog) and on
some equipment it may be labeled as YCbCr. Since this input supports all
interlace and progressive resolutions from 480i to 1080p, you can
connect it to both legacy and new equipment alike as long as it has
component video output. For a list of supported resolutions, please see
Specifications Section titled “Supported Input Formats” found later in
this manual. For example; if you are using the DVI output of the scaler to
connect to the HDMI input of an HDTV, you could use the YPbPr input
to connect your legacy DVD player, or PlayStation™ equipment to your
HDTV.
VGA:
This is the analog RGBHV signal from a PC. A wide range of
resolutions from VGA to WUXGA is supported. For a list of supported
resolutions, please see Specifications Section titled “Supported Input
Formats” found later in this manual. This input provides a convenient
way to display your PC’s video without losing clarity on any TV or
HDTV as long as the TV has either HDMI™ or component inputs. Since
the AC139A uses state of the art video scaling, often you will achieve a
sharper image on your LCD even if it has a VGA input!
DVI: This is the digital input to the Scaler. You can connect to the DVI-
D or DVI-I outputs of any PC. The DVI input of the unit supports HDCP
encryption. This means that it is compatible with Content Protected
HDMI™ video sources. However, the audio of HDMI source is not
processed through and you should configure and use the separate audio
output of your HDMI™ source. The DVI input of the scaler can handle
most HDTV and PC resolutions. For a list, please see Specifications
Section titled “Supported Input Formats” found later in this manual.
Note about DVI input Cable
If you will be connecting to an HDMI™ source you will either need an
HDMI to DVI cable or an HDMI to DVI adapter.
If you will be connecting to a DVI source you will then need a male to
male DVI cable. DVI-D cables will work since they do not have the
extra pins that DVI-I cables have, but since the AC139A utilizes a
