INTRODUCTION
PACKAGE CONTENTS
FEATURES
The Atlona AT-HD420 converts HDMI to a VGA or component output plus stereo audio. It enables an HDMI
source to connect to a PC monitor, Projector or TV. Its high bandwidth capability supports a wide range of PC
monitor and HDTV resolutions up to 1920 X 1200 or 1080p.
The converter is also capable of de-embedding audio from the HDMI source and converting it to a stereo 1/8-inch
interface. This will allow the user to connect it to a set of speakers, an AVR or any other audio device.
Note 1. The AT-HD420 is a format converter only; therefore user would have to choose the resolution on the
HDMI/DVI source which he/she would want to see on the output. The converter will not scale the signal and
therefore it is very important to select the proper resolution on the originating source
Note 2. If an HDMI source includes HDCP(High-bandwidth Digital Content Protection), the AT-HD420 out-
put does not support HDCP decryption, therefore no image will display.
• 1 X AT-HD420 (HDMI to VGA or component video format converter)

stereo or PCM.

CONNECTION AND OPERATION
PANEL DESCRIPTION

1. Output Format switch: Set the switch to VGA when your HDMI source equipment is connected to a PC
monitor or projector. Use a VGA cable to connect between the AT-HD420 VGA out and the VGA input of your
PC monitor or a projector. Set the dip switch to component video when your HDMI source equipment is con-
nected to the component video input on an HDTV display. Use the included VGA to 3 RCA adaptor cable to
connect the AT-HD420 component out to the component input of your HDTV.
2. HDMI input: Connect the HDMI input port of the AT-HD420 to an HDMI or DVI output port of a source such
as a DVD player or PC.

TROUBLESHOOTING
1. No Picture:
• Ensure that the source output resolution is supported by your display. Check displays documentation for list
of supported resolutions.
• If your source is a Blu-ray player most purchased media is HDCP (copywrite protected by the studio) pro-
tected which is not supported by the AT-HD420.
2. Color Accuracy:
• If the display exhibits a green hue over the image on your HDTV then check the component cable to make
sure all colors on the cable connectors match the displays input jacks. If the colors match try another cable
as it is possibly defective.
