List of Compatible Signals
Set the computer and AV equipment output signals so that they match the input signals compatible with
the projector.
If the image flickers, blurs, or is not displayed, check that the resolution and frequency of the input
signals is supported by the projector.
• Images with a resolution greater than 1280 × 800 are compressed when displayed, so some of the information may be lost or the image may deteriorate.
