Dell 3100MP Projector - No Signal Check Cable

Projector starts up and shows DELL logo, but then goes to a blue screen and says "No Signal - Check Video Cable". I have tried replacing the cable with a new one and also tried connecting it to different PCs. Is there anything else I can try other than a repair shop?

I think I had a similar problem- are you connecting to the right socket.? The VGA on the 3100MP socket is `VGA out` you might need to connect to the `DVI monitor in` socket ,possibly needing a male DVI connector that connects to a male VGA lead.(Maplins , if you are in UK ,sell one for about £10)

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.

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.

We are using a Dell 2300 projector. The Power


check that you have a signal going out of the monitor socket on your lalptop.

On Dell with projector connected and switched on, press the blue fn button bottom left usually, and while holding, press one marked CRT/LCD, (maybe f8) this will cycle to the following.
laptop only, laptop and monitor, monitor only, while holding Fn button press until you have desired outcome.

I have 5 Dell 4310 WX projecors and I would like to display my logo when they start-up. Can this be done with the projector only or is a laptop necessary for this to happen?


I believe the Dell logo is hard-coded for the Startup, but you can change the Wallpaper form the Dell logo, to an image of your choice:

From the Setup Menu, or Others Menu, you can go into:
SCREEN SETTINGS—Select and press checkmark to activate screen settings. The screen
settings menu consists of the following options:

CAPTURE SCREEN—Select and press checkmark to capture the screen display, the following message appears on the screen.

NOTE: To capture a full image, ensure the input signal that is connected to the projector is 1280 x 800 resolution.

SCREEN—Select Dell to use the Dell logo as wallpaper. Select Captured to set the captured image as wallpaper.

RESET—Select and press to delete the captured picture and set back to the default setting.

Dell 3400mp not getting signal from Macbook


If you were using the Apple S-video adapter to connect to your Dell projector, please realize that MacBook models with NVIDIA graphics cards do not support this adapter. Otherwise, please be more specific about what model Mac you have and what adapter cable you are using.

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
