NOTE: Macintosh computers require a specific power-up sequence: the projector must be turned on before you turn on the computer.

Troubleshooting

If you’re experiencing trouble with the projector, follow these steps to make sure everything is properly connected before you call Technical Support for assistance.

1Check cable connections. Verify that all computer, CableWiz- ard and power cables are properly connected.

2Verify that all power is switched on.

3Verify that the projector has not been switched off with the standby button on the keypad.

4If the projector still doesn’t display an image, restart the com- puter.

5If the problem still exists, unplug the projector from the com- puter and check the computer monitor’s display. The maxi- mum resolution that the 725 can display is 1024x768 pixels, preferably 800x600; the maximum resolution that the 730 can display is 1280x1024 pixels, preferably 1024x768. The problem might be with the graphics controller in your computer rather than with the projector. When you reconnect the projector, remember to turn the computer and monitor off before you power up the projector. Power the equipment back up in this order: projector, monitor, computer.

6If you’re using a laptop computer and it is not displaying your presentation, make sure you have activated the computer’s external video output. Most laptop computers do not auto- matically turn on their external video port when a secondary display device such as a projector is connected. Refer to page 53 for more information.

7If the problem still exists, read through the problems and solu- tions in this chapter.

The InFocus LP 730 is a high-performance LCD projector that caters to the needs of both business and educational environments. Known for its reliability and versatility, this projector is designed to deliver exceptional image quality and user-friendly functionality, making it a preferred choice among professionals.

One of the main features of the InFocus LP 730 is its impressive brightness, measured at 2,500 ANSI lumens. This high lumen output ensures that images remain vivid and clear, even in well-lit rooms. Coupled with a contrast ratio of 2000:1, the LP 730 is capable of producing deep blacks and vibrant colors, making it suitable for video presentations as well as detailed data projections.

The LP 730 boasts a native resolution of XGA (1024 x 768), which is ideal for displaying text and images with sharp detail. This resolution is particularly beneficial for presentations that include charts, graphs, and intricate visuals. The projector also supports various video formats, including 720p and 1080p, allowing for flexible input options.

The presence of a USB port allows for quick and easy presentations directly from a USB drive without the need for a computer.

The LP 730 incorporates advanced DLP technology, which enhances color accuracy and overall image quality. This technology ensures that colors remain true-to-life while minimizing the rainbow effect that some viewers may experience with traditional projectors. Additionally, the projector features a built-in speaker system, which delivers clear audio for presentations and videos, eliminating the need for external speakers in small to medium-sized rooms.

Portability is another strong point of the InFocus LP 730. With its compact and lightweight design, it can easily be transported between locations, making it a practical choice for traveling professionals or educators who need to present in multiple venues.

Finally, the projector is equipped with energy-efficient features, including a power-saving mode that reduces lamp brightness when the projector is idle. This not only prolongs the lifespan of the lamp but also lowers energy consumption costs.
