Connecting A Video Device - InFocus SP4805 User Manual

Connecting a video device

You can connect video devices such as VCRs, DVD players, camcorders,
digital cameras, video game consoles, HDTV receivers, and TV tuners to the
projector. There is also an audio input via the red and white A/V connec-
tors. You can connect the audio directly to the projector to get sound from
the built-in speaker, or you can connect the audio to your stereo system via
the Audio Out connector.
You can connect the projector to most video devices that can output video.
You cannot directly connect the coaxial cable that enters your house from a
cable or satellite company, the signal must pass through a tuner first. Exam-
ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat-
ellite TV boxes. Basically, any device that can change channels is considered
a tuner.
Before connecting your projector, you should decide which aspect ratio you
want to use. The projector's Aspect Ratio setting is accessed through the
projector's Picture Menu. See page 33 for more information.
What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. HDTV and
most DVDs are 16:9, which is the default for this projector. This projector is
not intended for use with 4:3 screens. When in 4:3 mode the projector places
black bars on both sides of the image. Native mode centers the image and
turns off the internal scaler so that any resolution larger than 854x480 is
cropped on the edges. Letterbox expands the image to fill the screen.
If you are projecting onto a screen, the size/shape of the screen may deter-
mine which aspect ratio to use. If you are projecting onto a blank wall, you
don't have the screen size restriction. What you plan to project will also help
you choose between 4:3 and 16:9. For example, most TV shows are 4:3,
while most movies are 16:9. If you have a 16:9 screen, then you should select
an aspect ratio of 16:9 for anamorphic movies and HDTV, and Native for 4:3
content. If you have a 4:3 screen you should still use 16:9 for anamorphic
movies or HDTV, but you also have the option of using either 4:3 or Native
for 4:3 content. Keep in mind that anamorphic movies only appear correctly
if the DVD player is set to output to a 16:9 television.
