My laptop can't connect to my projector

[Eddy_345]

My laptop Acer Aspire is not able to properly connect to my optoma projector through VGA. This is the only laptop in my house that is not able to connect properly. I don't know whats wrong. It was working on the projects before this but I don't know why it's not working for this. Maybe something happened in between and it's now broken or something. My projector also has a HDMI option but my laptop doesn't support HDMI Cable input. I'm running windows 10. Please help me fix this problem of mine. When I put in the cable, the screen resolution automatically changes, that is only if the cable is connected to the project, that show's that it's able to detect the current. But there's no output signal being detected in my projector.

Typically there is a function key setup to switch displays, for a laptop.

If you're talking about the fn + F5 button, I've tried it. It's not that.
