Question about Toshiba TLP T70M Multimedia Projector

1 Answer

Unsupport Signal message

I have a Gateway GM5664 desktop computer and a Toshiba TLP-T70M projector. Recently, when I turn on the projector and computer and have the projector set to display computer, all that shows up is a question mark in the upper left corner and a message of "Unsupport Signal." I have flipped the outputs on the back of the computer to where the signal that would go to the projector went to the monitor and the correct image showed up on the monitor so I feel the output at the computer is fine. Any suggestions? I don't see anything about this in the owners manual. Thanks!

Hello

This is caused by the computer giving out a signal, with either too high resolution or refresh rate for the projector to understand.

So this is completely normal behavior for the projector, tv's and even computer monitors will give you this message if the input is not of its liking.

Before connecting the projector, turn down the resolution to 1024x768. this can be done from start -> control panel -> screen resolution or display. And from there possibly settings page.

Then check the refresh rate, set it to 60HZ, this can be done by clicking advanced and then monitor.

Blank screen when Gateway GM5664 turned on


How do you know your mouse and keyboard work if you have a blank screen?

What motherboard did you put in it? Did you install a video card or using a built in video card? How many beeps? Do you have a spare video card to put in the system and try that?

My Toshiba TLP-XD2000 projector reads "unsupported signal" when it is plugged in to my Dell Inspiron 600m laptop. It has worked for about 8 months perfectly and then when I plugged it into another computer...


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.

N o signal


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 !

Unsupported Signal


Hi Circuitrider

Just change the resolution on your PC to match that of the Projector i.e. XGA Projector = 1024x768 resoltuion.

If the problem still persists , the Mainboard is at fault and will need either replacement or repair.
