INTRODUCTION  
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.

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.
