Unsupported Signal After I connect my Dell Inspiron Laptop to the TLP-S30 projector, start the projector, and then turn on the computer, the message on the screen is: "Unsupport Signal." This process had been working well, but suddenly this problem prevents my use of the projector.

Press <Fn><F8> to switch the video image between the display only, the
external device only, or the display and the external device simultaneously

one of the fans arent working. there should be at least 3- one for the lamp, one for the power supply, and at least one for the lcd panels. you should be able to see the one for the lamp and power supply from the outside. if both are spinning, it's the other one, which you might be able to see from the bottom.

make sure the cable is good. then make sure the resolution matches.

There are two things it could be...

First, how far are you trying to run the cable for? When you run longer distance a humbucker might be needed. Or it means that the internal distribution output has bad vertical and horizontal connections.

reset the settings to factory default. when you plugged it into the 2nd computer, it searched for matching resolution, to no avail. when you put it back with yours, it was on the default setting.

reset the laptop with the video cable hooked up

Click the 2 box on the display settings and put a check mark ano the box that is say to extend the view on to this monitor. Hope this Helps.

Hi momawarbucks

Check if your secondary screen is attached by going to desktop and right click , then go to properties and advanced.

Also check if your refresh rate is on 60-70 Hz

And that the resolution your PC is on , is supported by your Projector - i.e. XGA Projector - 1024x768

Good luck and thanks for using Fixya !
