"No Signal" on projector

Question

Hello,

I have just been given an LCD projector with a manual in English...

I have connected it to my desktop computer, but when I turn on the projector it says 'No Signal' and the screen is upside down!!

I have spent 5 hours online looking for a solution but I haven't found anything.

Please, if you know how to fix this, help me!

Thank you in advance.

Configuration: Vista

You need to activate the second "screen" in the PC display settings, and switch the projector to the input where the PC is connected.

Right-click on the desktop, personalize, and at the bottom, display settings.

Ok thanks, I'm at the office now but as soon as I get home tonight I'll try and let you know.

Re! I went to the Display settings, but what do I do once I'm there?

stewartia · Answer

The projector needs to be turned on; usually, a second screen is "grayed out," activate it and adjust its resolution and refresh rate.

On your motherboard, do you have the option to change the graphics card?

Well, I don't know!

I just want my projector to work; I don't care if I can't have both screens at the same time!

Plus, last night I plugged my projector into my PC while it was off, then I turned on my PC and my projector and, as if by magic, there was an image: the Windows startup.

But after a minute, the "No signal" message came back!

Set the resolution on the PC screen to match that of the projector and set it to 50 Hz. Turn everything off, connect the projector, and then turn it back on.

ok ok but how do I set the resolution?

Do you have the brand and the model number of the VP? It’s usually written in the manual, but that will help me assist you.

feeflower77 · Answer

The manual is in English!  I'm at the office right now, but I could give you the references as of 2 PM  In any case, thank you for your help.

I'm sorry for not responding earlier!  My VP is a "Digital Galaxy" DG-737 / 747 LCD Projector.
