Connecting external monitor to a laptop

When we connect an older ADI 19" monitor to a Vista laptop, it shows no images even though the monitor power light is green, indicating a video signal.

I played with all the display settings (refresh rate, resolution), the function-F5 key to select the display, etc. In display properties it shows the monitor as a non-pnp generic monitor.

When I connect a different monitor to the laptop it runs instantly.

When I connect the ADI monitor to a different laptop, an older WinME laptop, it works fine instantly.

I looked online to find a monitor driver, but when I tried to install it, Vista said it already had the most up to date driver installed. And monitors usually run anyway even without the driver, so I am not sure if looking for a driver is the way to go.

Any ideas?
Thanks

Might be of more use if we knew your system specs (lower left corner) so we know what video card, memory, etc

Hello YoVincenzo,
Can you right click desktop > Personalisation > Display Settings, and tell me how many monitors are showing there, thanks.

I am not at the location, it is my friend's computer. But I remember it very well.

In Display Settings, it shows two monitors. When I click the first one, it shows Multiple monitors on Intel 965. When I click the second one, it shows non-pnp generic. I've played quite a bit with the settings for the second monitor, for refresh rate, resolution, and more. Also tried different settings on Fn+F5 video output setting, but to no avail. I found one setting in the BIOS for auto detect of external monitor or always on external monitor, made no difference. (The laptop works fine with a different external monitor)

Thanks

Have you tried a restart with the second monitor plugged in ?.
I seem to remember i had a similar problem and a simple restart fixed it, i get the feeling it's not going to be that easy, but i would kick myself if it was, and i didn't say anything lol.

non pnp (plug and play) suggests it may need drivers , if its non pnp yuor bios will effectively ignore it , so its no use tweaking that :(

A few laptops I have worked with, not recently, had a button in the Windows properties in the section for display size and the video card. You had to click on the button to activate the external monitor connector on the laptop.

I haven't seen it in several years, so it might have been done away with.

Glad to see you got it working !

OK your post made me realize my last post was misleading. I was just writing what the the dialog was reporting, that Windows Device Manager says the device is working correctly, but nothing has changed-The monitor is still not working.

Sorry for any confusion. I was wondering why there were no more responses.:confused:

Hello YoVincenzo,
I keep coming back to this post, frustrating as it is.
Does the video adaptor properties have any adjustments, frequency, or anything that might be useful ?.

By frequency, do you mean refresh rate? I've adjusted refresh rate and resolution quite a bit, with no luck. Also any other settings I could find in display properties.

Thanks

This is driving me nuts, (i dread to think whats it's doing to your head), you have tried it on an older machine, can you try it on a newish machine, maybe it's just a compatibility thing, but for the life of me i just don't buy that. If it's getting a signal it's gotta firkin well work, :mad: or at least you would think so.
No bent pins anywhere ?.
