No signal to projector

When connected to projector, my computer does not "project." The projector keeps saying "No Signal Found." I press "Function F7" as I normally would, but it doesn't work.
It's a Lenovo T61 laptop and I'm running Windows XP.
I may have deleted the program that send signal to projector. How can I fix this?

SOURCE: Laptop display will not project onto screen

A couple of possibilities...

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.

I am trying to set up an InFocus LP400 projector with my computer. I followed the instructions using the CableWizard Lite cable for my laptop pc and get no projected image. I used the suggested port...


Hello,

start the connecting all over again, by following the steps below:

1. Turn your computer off.

2. Connect the cable from the computer to the projector. If you want to have your monitor to be hooked up as well, connect a splitter to the video out port (DVI or VGA). You can also just hook the projector up to the second port on your video card (If you have one) or if you have a laptop, you can connect to the video out port on the back.

3. Turn the computer on and boot into your desktop.

4. Turn on the projector. Most projectors have an auto detect function, that will detect a video signal and auto configure the projector to display that signal. If you have a laptop, you have to hit a function key to activate the second display. Usually this is FN Key + F5 or one of the F Keys across the top of the laptop keyboard. It looks like two squares, one empty and one with something in it.

5. Adjust the focus, brightness, contrast, and color on the projector.

6. Aim the projector at something white. Try not to aim it at something highly reflective.

7. Step back ... Load up your favorite game or video ... and enjoy.

Your project should work, after following the above instruction.

Good luck.

Searching for signal


The problem is with the computer, not the projector.
There are special function keys, generally with blue lettering along the top row of your keyboard. Find the one that looks like a double screen or says "CRT". Also locate the blue function key [FN], probably on the lower left on the keyboard.

Press, and hold, the [FN] key and press the [CRT] key to change to dual screen.... and wait for several seconds for the projector to detect it. If it still doesn't work after you have waited, press the key sequence again (there are 3 different screen settings).

1. Computer Screen only (normal)
2. Projector Screen only
3. Both Computer AND Projector screens

What settings should I use for acer x1260 to dell d520 laptop? Projector says "no signal" - have changed avg cable - no difference.


The max resolution on the projector is 1024x768. But the problem you're having sounds suspiciously like the laptop not sending out a video signal...you have to *tell* the laptop to send out an image to an external display. On one of the function keys, like F4 or F8, there will be a small TV screen symbol. You have to press and hold "alt" and then press the key with the symbol. The initial setting is obviously for the laptop only. When you press the keys for the first time, you tell the laptop share the picture with an external display (your projector). Press the keys a second time, and the laptop ONLY displays an image from the projector. And, press the combination again, you're back to just the laptop.The DLP projector should have a menu selection for "auto" under the input menu...that is the easiest and most trouble-free setting. Whatever you connect to the projector, it automatically seeks out the signal and connects to it.---Rick

No Signal when plugging into laptop


On your laptop you have the ability to toggle the external display on/off/both. On several laptops I see, it is a combo of teh Function Key+F4 (or F5). The key for your laptop (you did not provide type) should be marked with an image of a projection screed or a monitor in a color matching function key; often blue.

With everything connected, press these keys to toggle from Laptop Display Only to Projector Only to Both.

If the problem is not your laptop, then verify the input source that the projector is looking for via it's menus or a button on the remote. Toggle the source if required.

Upon setting up your equipment it is very important that you turn on the projector first. You will see a blank projection image, now turn on the computer, (confirm your cables are connected properly). When using a lap top computer you may need to disable your computer's display screen. First locate the "function" key at the top of your keypad that reads "LCD", "CRT" or it may have an icon that resembles a computer monitor. By pressing the "FN" key and the corresponding "function" key you will be able to obtain the image from the projector only. This is known as "toggling" the image.

Unable to connect sanyo projector to sony laptop error is no signal Thanks in advance shaik


You need to use the Fn key on your computer to change the signal so your monitor signal projects through the projector.
On my computer I use the Fn key and F4 and it will then send the signal through the computer to the projector.

LCD projector no signal message


Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.

Dell 2200mp searching for signal


One problem may be that you must tell the PC to send the signal to the external monitor. Usually, if you hold down the function button and hit the F5 key you will see several options on the screen. (Other laptops use different function keys. Look for the one that shows two tv screens. You want the option which shows the laptop and the external monitor.) To advance between options, you hit the F5 button again and it moves over to the next option.

My computer needs me to lower the resolution on the laptop in order to send the signal to the projector. If you also need to do that, you can do it in Control Panel, Display, and Settings, and lower the resolution on screen number 1.

Doing both of these things should work.

Also, confirm that it is finding signals by hooking it to a DVD or video and see if it finds the signal through one of the other ports.
