How to fix InFocus LP 850 when there is no startup screen?
If your InFocus Projector doesn't show a startup screen, ensure the power cable is properly plugged in. Then, press the power switch and the power button. Also, make sure to remove the lens cap.
What to do if my InFocus LP 850 says 'Signal out of range'?
If your InFocus Projector displays 'Signal out of range' instead of your computer image, adjust your computer's refresh rate. You can find this setting in Control Panel>Display>Settings>Advanced>Adapter (location varies by operating system). Setting a different resolution on your computer may also help.
Why is the image fuzzy or cropped on my InFocus LP 850?
If the image on your InFocus Projector appears fuzzy or cropped, set your computer’s display resolution to the projector's native resolution. Go to Start>Settings>Control Panel>Display>Settings tab and select 1024x768 for LP840/850, or 1400x1050 for LP860. If you are using a laptop, try disabling the laptop monitor or enabling dual-display mode.
