There is no input yet meaning, it is not yet properly connected to your computer. Check the cable connection. Please make sure that the computer or laptop is already turned on.

Sharp Notevision PG-C30XE problem with computer display


There are 3 different types of analog video signal ports on your projector; s-video, composite video, and RGB. Which one of the three are you using to connect your PC to?
The projector's resolution rate is XGA [1024 x 768]
If you are using a VGA cable designed and capable of handling 640 x 480 resolution; then it will not support XGAs 1024 x 768 signal. On the other hand, if the coaxial cable you are using is a multi band one that is capable of supporting VGA and XGA resolution signals, most likely the problem is not with the cable- although I have come across brand new cables that are defective.
Please let me know if this helps or else we'll try another approach :)

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.

Do i need to do something special to hook my laptop up to a mitsubishi projector using a VGA cable other than fn and f8 on the Dell laptop?


this should be enough to ensure signal is going out of your monitor port on the back of your Dell.

the projectory also supports montor to montor cable rather than vga

suspected for VGA the projector needs to be set to video input
and for monitor to monitor cable to computer input setting.
if picture is not seen straight away cycle FN combination until picuture is seen.

Full Desktop does not appear, video does not show.


You must tell the laptop to change display mode--there are 3...Normally, the key-press is something like "function key, F4"--look for a small tv screen symbol on one of the "F" keys--default mode is "laptop only", Press and hold "fn" and then press the appropriate "F" key, the laptop will switch to "laptop/external display". Another set of key presses will get "external display only" mode. And, finally, the next sequence will bring you back to the default mode. Make sure you turn on the computer and *then* turn on the projector to head off any sync probs.---Rick

"No signal" even though connected to computer


You probably have to tell the laptop to send a video signal to an external display--(i.e. <altF4 or <altF8) The proper function key will have a TV screen symbol on it. Default mode is "laptop only" By pressing and holding the alt, then pressing the appropriate function key, the laptop will switch to the next mode, laptop/external display. The last mode is external display only. By pressing the sequence again, you'll return to "laptop only" mode.

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.

No signal


Hi and welcome to FixYa,

Initially, the "No Signal" error message indicates just that, it is not receiving anything or that the signal it receives is beyond its capacity. With this in mind, pls check:
  • the cable connection from PC to Projector;
  • that the PC is set to display on a 2nd monitor, TV or Projector depending on the capability of the PC's video card (Twin View or Dual View); or
  • as main monitor;
  • lower down the computer's Screen Resolution and/or Screen refresh rate.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
