Question about Projector Accessories

Computer used to work with projector, and now doesn't?

My computer used to work when connected to a projector. There is now no image when I connect it, but the projector recognizes it (blue screen goes black). There is just no image projected...it stays black.

I have tried this with 3 projectors, and all don't work. Is it my graphics card driver? I have no ideas...

I have a Dell Inspiron 1520.

    Yes it's Fn F8. When I do this, that's when the screen (projector) goes black, but does not project the image.

Have you tried pressing Fn F5? On my system (HP), by computer monitor goes dark when I connect the projector. Pressing (Function) FN F5 toggles the video between Computer Monitor, Projector, or Both.
Check the function settings for your computer. On my Compaq laptop at home, the video function is F4, so there may be different settings for your computer.
Good luck!

Have you tried pressing Fn F7? when you hold down the Fn key you can tap F7 and a little icon will come up with 3 boxes, LCD (this means projector only) Monitor/LCD (this means the computer screen will be on along with the projector screen,) then the last box will say Montior (This means you will have only the comuter monitor screen on) To get the computer screen and the projector both on to work simulatneously you want the Monitor/LCD

Shut down after 30 seconds


Many projectors shut down if they cannot find anything attached to them.
Make sure you have a computer attached and sending an image out to it before you hit the projector reset button again.
It's a bit like the chicken and the egg since some laptops won't send an image out the cable unless it senses a projector, and the projector shuts down if it does not detect an incoming signal fast enough.

Go into the settings menu of the projector and turn off the auto source function, then select the input that you are using.

if using a laptop you may have to simultaneously press your FN and relevant 'F' key to send the signal out to the projector. The 'F' key usually has an image of two side by side monitors or it says LCD/CRT. Wait a few seconds each time for the signal to be sent to the projector. Sometimes you may have to repeat this action 3 times to get the image on both your laptop and your projector.

good luck

HOW TO USE DAYLIGHT PROJECTOR IN STEP BY STEP


Hi LCD projectors have revolutionized the audiovisual industry. With a few clicks of the mouse and strokes of the keyboard, whatever you type on your computer appears instantly on a projection screen in real time. If you have never experimented with an LCD projector, however, do not worry. You can learn how to use an LCD projector.

  • Plug the LCD projector in to a power outlet. Completely plug the power cord in to the back of the LCD projector.
  • Step 2Use a VGA cable (usually a 15-pin male to male) to connect your computer to the LCD projector. Insert one end of the cable into the VGA connector (sometimes this connector is blue) in the back of your computer and do the same in the back of your LCD projector. If the LCD projector has more than one VGA connector, choose the one that says something like "line in" or "in from computer."
  • Step 3Power on your laptop. Turn on the LCD projector. It may take a couple of minutes to warm up. Open the computer file or document you wish to display. When you are ready to project your image, press "Function" (Fn) plus "F8." This combination of keys sends your computer's display to the LCD projector.

    I get a blue screen on my misubishi sl1 projector lamp and no signal appears on the screen


    Hi

    Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have).

    There are also known known hot-key combinations used to switch the laptop to its external VGA mode. If you are using a laptop.

    Check the cables as well if properly connected both on computer and projectors end.

    Hope this helps

    Do you need software on pc to use the projector


    Generally speaking, you shouldn't need any special software to use a projector connected to your computer. Usually you only need to set up the projector as a separate monitor under the Windows display properties. This is often done simply by pressing the Function key + one of the numbered keys F1-F12 on most laptops.

    I'm more of a hands on fixer but here are some options to look at. Have projector up and running before turning on or plugging in whatever device you want to project. Some projectors are picky about this and some arent. Next would be to look at the pins on the cable you are using if you are using a VGA. One pin ascew can throw off the ability to transfer the image. Or maybe she's just trying to tell you that she's ready for retirement. It could be the sync mechanism and cables internally wearing out.

    Panasonic PT-L701e - colour fault, blacks are blue with lines


    Can you connect a computer (vga) signal to this projector? I'd like to know what your "white" computer screen does on the projector....example, Excel spreadsheet....

    I am leaning towards these problems, a bad video card...or worse delamination of one of your LCD panels and possible polarizer burn in the optical engine.

    Best Regards,
