I [can't] see what you did there...

I'm trying to setup a computer to be used with a projector, and only a projector [no monitor] but I can't get ANY sort of image to show.

It works perfectly fine with a monitor and we have others that do it without any problems.


I'm getting NO error messages on either the computer OR the projector. Apart from "No signal".


It's a desktop and I've tried the registry hack, but it's had no effect at all. I can't even open the mobility centre, as it's still registering the computer as a desktop.


When I use a VGA splitter box, it's a bit better. It shows a black screen on both the projector and the monitor, but at least it's getting a signal.

The splitter isn't an option in the class, as there is a distinct lack of power outlets.


Any advice on what is going on would be much appreciated.

I've tried 2 different projectors, multiple cables and I know the projectors are fine.

The class one works with my laptop, the one I'm using to test it with works fine with other computers.


The issue seems to be that windows dosn't detect a monitor, so it doesn't bother to send the signal.

well i would try reimaging the computer maybe some kind of windows fault DAM WINDOWS
unless your GPU is on its way out
is it on board Graphicks or card

Onboard. I don't have a spare graphics card I can stick in.

I assume we have checked that the output resolution is compatible with the projector?

If this was the case, I'd be getting "Out of range".

We actually had THAT problem in a few classes with older projectors.

Tried removing then replacing the cable while windows is up ? Have as issue with a splitter where the image is off to one side - if I pull/replace the cable it resets itself.
Not ideal. We had a projector do this also, the input board was broken (just happened to be the 4m up in the air hall projector)

Is it a windows 7 machine? have you tried rolling back or updating the graphics drivers? I had a machine where if you plugged in a monitor it was fine, as soon as you plugged in the splitter box the picture had coloured lines through it, computer would lock up and all manner of weird things

[Admiral208]

have you tried Win+P to scroll throught the different projector modes?

[clareq]

Can you use remote access to connect to the machine when the projector is connected and change resolutions?

Does it display POST? There is a BIOS setting on newer intel boards for a default display connector too.

Sorry, I am sure you have done this but have you set the mode to projector only? We have a couple that won't show unless they are put like this

I don't have that option... It's a desktop I'm trying it on.

The "projector only" setting, along with the UI you use to set it, is locked out on desktops.

Nope. I can get to the resolution settings, but can't change them remotely.

Does it display POST? There is a BIOS setting on newer intel boards for a default display connector too.

I've had a look and there's nothing. They're not new machines...



Le EDIT: Holy carp! Win+P works on desktops... It wasn't working yesterday.
