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.
