Solved laptop does not want to switch to additional screen

Custom / CUSTOM

Specs: windows 7, 2.401 GHz / 2047 MB
I'm having this laptop : HP Pavilion
I have this screen : a Dell screen with both DVI and VGA connector

I had another laptop, which I connected to that screen, using the VGA cable. No problem. The computer I normally work on, is using the DVI connector.

OK, so this new laptop doesn't have a VGA connector. But, it has a HDMI.
And, I have this connector : a female VGA to male HDMI

All connectors can connect as designed. But .. nothing happens. I mean, the separate screen doesn't get any signal at all. My laptop, running Windows 7, doesn't mention anywhere that it sees another screen. It just knows 1 screen (it's own).

All screens can run 1080p, the adaptor piece supports up to 1080p.

Additionally, the laptop doesn't seem to react when I tell it to switch screen. It has a Function key (the famous Fn keys) for that, but it doesn't do anything when you press it.

My old laptop (not an HP) would, while you press that key, lose the signal on its own screen (as is logic) at some point, but that doesn't happen on my HP laptop. I thought the keys were not working, but others do.

But, the light intensity keys (other Fn keys) do not seem to work. So (to summarise) : some Fn keys work, others not.

Question is : how do I get my laptop to show on the other screen. I don't want dual screen setup, just output to the other screen.

I was thinking something wrong with the connector, or maybe there is no ouput at all from that HDMI port ?

It works ... I've installed HP Support Assistant, and by means of that there's an update of video software and/or drivers. After that, the additional screen can be displayed. Quality is lower than when using same screen with DVI cable, but that's something else.

"I have this connector : a female VGA to male HDMI"

Have you ever used the adapter successfully before? VGA is analog, HDMI is digital (so is DVI). I think you will need an HDMI to DVI adapter.

No, that adaptor is brand new. And, I cannot really test it elsewhere.

If the adaptor cannot work, why do they sell it ? I read on 1 site something that goes in that direction : technically, it doesn't work.

Can't use HDMI to DVI connector, as a VGA cable probably won't fit in there ;)

But you said your monitor has both VGA & DVI. You obviously can't use the VGA but what's stopping you from using DVI other than lack of the proper adapter? You have a couple of different options.

You're right, the screen has a DVI input, but that input is used by my fixed desktop. The idea of 2 inputs for a screen, is that you can connect both cables, and let the software arrange which input is chosen.

Additionally, both input are of a different type, but I can tell you it does work if you connect both, as in the opening post is stated, I did that with my desktop and my old laptop. The old laptop had a VGA connector, while the new does not.

Switching cable input (a Y connection) is an option, or buying a screen with multiple DVI connectors.

There's no solution close to the real one, other than the one I mentioned, but I cannot "Select that as Best answer".

So, if somebody wants to get a post with that, repeat the solution I mentioned.

In a few days the regulars here will get an option that you are not getting and probably choose #5 as the best answer for you.

You have to be a little bit crazy to keep you from going insane.
