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 receive rs 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.
• Visit the Service and Support web site at http://www.infocus.com/service for further proje ctor support, including FAQs, firmware, user guides and
connectivity information.

Common Issues
SYMPTOMS: Light bar rolling from bottom to top
Solution: This is probably a ground loop issue. Ground loop effects
are caused by a differential in the power between the source and
projector. The solution is to ground the source and projector. Use a
ground loop isolator and/or plug both the source and projector to the
same power outlet.
A rolling bar can also be caused by poorly shielded cabling. Make sure
you use quality cables
SYMPTOMS: Static, noise, or video artifacts in video image
Solution: Usually you can eliminate a lot of video defects by using
high quality cable in as short a length as possible. For the best results,
we recommend using DVI or component cables with the projector.
Composite and S-video cables do not support high definition and
produce lower quality video. Try to keep cable length to less than 10
feet. If the setup requires a longer cable, make sure to use the thicker,
well-shielded cables.
SYMPTOMS: No video image from the projector
Solution:
• Check the coaxial cable connection to the HDTV box.
Typically, there are two coax connections on an HDTV
receiver: To TV and Cable In. Make sure the cable is securely
connected to the Cable In port.
• Make sure the projector is searching the correct input (see the
projector user’s guide). If Auto Source is turned off, you need
to manually change the source that the projector is searching.
Press the Auto Source or Video button the projector keypad or
remote.
• Try a different video cable. The cable may be defective.
• Some video ports do not accept progressive signals. Refer to
connectivity chart on the Service and Support web site.
SYMPTOMS: Image is not perfectly rectangular (keystoning)
Solution: When a projected image is wider at the top or the bottom
(horizontal keystoning), or taller on the right or left side (vertical
keystoning), the projector is not perpendicular to the screen, either in
the vertical plane or the horizontal plane.
If the sides are angled, then you need to raise or lower the front of the
projector. Also, most projectors have digital vertical keystone
correction that you can adjust in the projector menu. If the top and
bottom of the image are angled, then you need to rotate the projector
left or right until the image is rectangular. Most projectors do not have
digital horizontal keystone correction.
SYMPTOMS: Image proportion is incorrect
Solution: The aspect ratio is set incorrectly on the projector and/or the
HDTV receiver. Make sure the projector and HDTV receiver aspect
ratio are the same. In the projector menu, you can adjust the aspect
ratio. In the HDTV receiver menu, you can adjust the aspect ratio.
SYMPTOMS: Sound is too soft from projector speakers
Solution: We recommend connecting the HDTV receiver to a home
theater audio receiver or amplifier to receive a more robust and quality
audio experience. The speakers on the projector are meant for very
small spaces.

Frequently Asked Questions
Which one is better: 480i (480 lines interlaced) or
480p (480 lines progressive)?
Most people cannot tell the difference between 480i and 480p.It
depends on whether the projector or the source has the better
deinterlacer chip. When you send 480i to the projector, the projector’s
deinterlacer converts the signal to a progressive signal. When you
send 480p, the video source’s deinterlacer converts the signal. We
recommend sending 480i to the projector.

What does Overscan do?
Some video devices cause noise around the edges of an image.
Overscan crops approximately 3% of the image to hide this video
noise. The disadvantage of this feature is that you lose part of the
image. Most InFocus projectors include this option in the menu when a
standard definition or interlaced signal is projected. You can turn
Overscan off through the projector menu or, with some projectors, with
the remote control.
Where is the luma detail, chroma detail, CCS and noise reduction
settings in the advanced menu? My advanced menu is not
matching what I see in the user guide.
These range of advanced options varies, depending on which video
source is active. The ones listed above are available only when
composite, s-video or 480i component signals are projected. If you are
sending digital, 480p, 720p or 1080i signals, these options are not
available.
At what cable length do I lose video quality?
The answer depends on the quality of cabling you use. Some cables
begin to lose noticeable quality beyond 10 feet. Higher quality cables
can maintain a clean signal beyond 25 feet. To guarantee the best
video quality, we recommend using heavy duty shielded cabling (for
example Monster Cable or Belkin). Use as short a cable as your setup
allows.
When is the projector’s deinterlacer used?
The projector’s deinterlacer is used when you send an interlaced signal
to the projector. If you send composite, S-video or 480i component
video to the projector, the deinterlacer is used. If you send progressive,
the source device’s deinterlacer would be used.
