InFocus HDTV Receiver - Manual (Page 6)

Tips
•
For the best sound, we recommend connecting the HDTV receiver to an audio receiver or a surround sound system. Only optical and coaxial audio
cables support 5.1 surround sound. With red and white RCA audio cables, you only receive 2.1 stereo sound.
•
If you are connecting your HDTV receiver to the M1 port, you need a special adapter. Refer to the Service and Support web site or the InFocus
user guide to reference the video connectivity charts.
•
DVI will provide the best signal. Current HDTV receivers have DVI and component connectors. Older HDTV receivers may only have component
video. Composite and S-video cables cannot transmit a high definition signal.
•
Check your HDTV receiver’s aspect ratio, output type and 4:3 override settings in the menu.
o Aspect ratio will control how the HDTV receiver will display the signal. Make sure the aspect ratio of the HDTV receiver matches the
standard aspect ratio of your projector. This will maintain the proportion of your video image.
o Output type is the preferred video format for high definition television stations. There are two choices: 720p or 1080i.
720p is recommended for the best video quality.
o 4:3 override is the video format for standard programming. There are two choices: 480i or 480p.
480p is recommended for the best video quality.
•
When sending video through DVI, ensure that your projector is HDCP compatible. All InFocus ScreenPlay models with M1 ports are HDCP
compatible. Most business projectors are not compatible. Consult the Service and Support web site or user guide.
•
We recommend DVI cables to not exceed 33 feet. When purchasing third party cables, always look at their rating. Cables may have ratings of a
shorter distance based on the signal format that you are using. Higher resolution formats will have shorter distance ratings. (i.e. a cable may be
rated for 33 feet for 720p, but may be rated only 15 feet for 1080p signal.)
•
All TV stations are not broadcast in high definition (720p or 1080i). Commercials and some channels will be displayed in 480i or 480p. Check with
your cable provider to verify which channels are displayed in high definition.
