Why doesn't the monitor screen appear depending on the computer?

I have two computers at home.

One is a laptop, one is a desktop.

I got a used LCD monitor from my friend this time.

When I connected this, I got a message that my laptop works well, but when I connected it to my desktop, I couldn't display the screen.

Why is that?

The connection itself works well.

I think it might be because the desktop is the latest graphics card.
I heard that there are cases where the old LCD monitor is not available on the latest graphics card.

I don't think it's connected properly.
