Dell 3100MP Projector : Showing a green image

When running either computer or SVideo signal thru my 3100MP projector, I get an image projected but it is green. I can sometimes get the image to return to normal by gently squeezing the external project case.

Thanks in advance,

Make sure you have the right input source selected. It may be looking for a signal from some input other than the one you're connected to. Beyond that, if it truly isn't seeing the input then you'll need to have the projector serviced.

SOURCE: Projector displaying yellow tint in center of screen.

The yellow tint is probably coming from the lens. It could be that the glass is tempered or possibly just needs to be cleaned.

I have a VT465 and the projection back ground is yellow and I can't get it to be white


If you are talking about the actual image that is coming from a laptop being yellow instead of white, then this is caused usually by a bad signal cable running between the computer and the projector.
To be more specific: All colours in a projector get made up in some way between red, green and blue. White is all of these colours at maximum, yellow is made by red and green at maximum but no blue. If your image is Yellow when it should be white, then the blue signal information is not reaching the projector. This can also happen within the projector or computer itself but is less likely. If your using a VGA cable (15 pin cable) then blue is run through pins 3 & 7 (positive and negative respectively), see if your cable is either missing these pins on either end or if they are bent, although it's more than likely within the cable itself. You can test this theory easily by trying to put something blue on screen, if the blue signal isn't getting through then it'll appear black.
If changing the cable doesn't solve the problem try testing the computer by trying to use a different one, and test the projector by plugging in a monitor or another projector.

If you are getting a yellow screen without sending signal and just trying to get the "no signal" or "no input" screen white, then this won't be the case.

Hi, is Dell 3100MP Projector is compatible with windows 7 laptop. I am Having message " NO SIGNAL, CHECK VIDEO CABLE" with Windows 7 but with Windows xp, the same projector works fine. Can anyone...


Hi,
In most cases this problem is cured by enabling the external VGA (or monitor) ouput on the laptop. The quickest way is to reboot the laptop with the projector turned on and connected. Usually the laptop will detect an external display is attached and enable the port.
It is also possible to manually enable the external display port. It varies from laptop to laptop but look for the "Fn" key at the bottom left of the keyboard, usually coloured green or blue. You should see a row of icons on the top row of "F" keys which is in the same colour. Look for the one which is either a monitor, or possibly says LCD or CRT.

Hold down the Fn key and press the key you located in the last step. There is usually a delay of a few seconds and then you'll find something may happen. Usually the external output will be turned on alongside the local (laptop) display. Repeatedly following the last step cycles through all available configuration options, including both on, local on, local off, external on, and external off.
This should fix it. Make sure that the correct input is selected on the projector whilst doing this. It will be labelled on the projector and it should display the same input message on screen.

Dell 4100MP Image Not Centered Thru Lens


No to your question. The lens is fixed it cannot shift horizontally only although there are projectors that can do this. I am sure you have the front foot retracted? I have had to do the same as you are doing or find a lower table.

Why does my projection look green if the colors are right on the computer?


I'm going to guess that you are using an RGB cable to connect to the projector and the projector is expecting a composite signal. The composite signal would be what uses a yellow connector when you use hte red/whjite/yellow type of cable. All of the video is carried by the yellow. If the projector is expecting this and you send out component (RBG in this case), then the only video signal processed is the green. Since the green also contains the sync signal, the picture will be seen but green.

Check the menus on the projector. You should find a video selection area that will allow you to change to component input.

Please update this if you have any more questions.

Won't project; can't find signal


Make sure that your computer was turned on first (don't ask me why). Then hold down the Fn key while pressing F8. Hope that helps.

NEC LT35 color problem


If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

Can't get computer images to project


Hi, I have found out that you must have the laptop set to an external monitor, in the control panel, display area, click on 2, then you must have the projector turned on before you start the laptop so it can recognize that the projector is there. Also make certain that you allow the unit to cool off by turning the lamp off, leaving the fan on and open the door where the projection lens is located.
