I set up the projector with a laptop to give a presentation in the gymnasium. I started the projector and then my computer; the monitor was very breifly projected onto the screen and then vanished. I tried the source button to no avail and have shut down and restarted several times. Please help!
There is a function f-key combo that you need to toggle on your laptop. I'm assuming that you are just using a laptop. Depending on the manufacturer, the f-key will have either a square with a line beside either side. Maybe it says ctr/lcd, or it looks like two squares side by side. You will have to press the fn key at the same time as the corresponding f-key, up to three times, depending on manufacturer.

Sharp makes light and compact projectors with low fan noise. Set the projector up in areas subject to minimal humidity and dust to avoid having to clean the lens too often. Remember that colors will get washed out if the screen is in direct sunlight. Learn a few troubleshooting techniques to get the most out of this work horse projector.
No Pictures, Sound or the Projector Fails to Start
If you have no pictures, sound or the projector fails to start, check that the power cord is plugged into the wall and that all the cables are connected to the rear panel. Make sure the remote control batteries are fresh. If you are using a notebook computer, make sure the screen output is correct. Check the Input Mode on the projector. Check the projector physically--is the lamp and cover in place? Check the key lock.
Connect a separate monitor to your laptop and verify that your laptop's external monitor port is functioning properly.
If yes, connect and power up the LP120. Press the source key on keypad. You should see the projector switch from video to computer.
Last option, does the projector display an "out of range" message on the screen. If so, reduce your laptop resolution to 1024 x x768.
hi try using the function key to toggle the display output form the laptop.every laptop when connected to an external display like projector works in the multiple diplay mode.in this mode the laptop vga output can be seen in 3 modes------ only laptop screen, only external deipaly(projector) & both laptop & projector.check this & this should work fine

Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).
I'm going to guess that you have a wide screen Dell laptop with a 16:10 aspect ratio and a default resolution of 1280X800. The wide screen is great BUT most presentation grade projectors do not have a native (pixel for pixel) 16:10 mode. Instead they still prefer a display input with a 4:3 aspect ratio like your old square CRT or standard definition TV. Why do they prefer a 4:3 input? Mainly because Powerpoint prefers to display a slideshow in a 4:3 mode. Because of this Dell, in their infinite wisdom, created the 'presentation mode' utility in an attempt to automatically convert the VGA output of your laptop from 16:10 to 4:3 on the fly. In my experience this is an annoyance at best and at worst can seriously impact the size and quality of the projected image.
The best thing you can do when you connect to a projector is ignore the presentation mode alert and manually set your laptop's resolution to 1024X768 for an XGA rated projector or 800X600 for an SVGA rated projector. This will cause your desktop to look stretched on your laptop but will give you by far the best projection image.
-toggle the laptop display using the FN keys and F5 I believe.
-lower laptop resolution to 800 x 600
-look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.

If you can nvigate to the On Screen Display Menu, you should see an "all images" section on the main menu. There you will find brightness, contrast, color temp, white intensity, and gamma controls. You should be able to make adjustments from that menu to sharpen and brighten the image.
