New monitor not picking up signal from old computer.

I have just got a new 24 inch HP LA2405wg monitor.
Has connected through a docking station to my laptop fine.  
I also had my old computer connected to my old monitor through a KVM switch.
But the new monitor will not pick up the display for the old computer.  

How can I get it to pick up the signal from the old computer?

What model and make of KVM are you using?  The KVM may not support the resolution or video refresh rate for the monitor.  You might try to adjust settings on the new monitor or set it to "Auto Adjust".

Ah its a cheap enough StarTech KVM.  
The KVM is working fine from the docking station with the laptop.  
I had got someone else's desktop to fix and it won't give a signal to this monitor, neither will my own old desktop.  
I tried AutoAdjust but when searching it says no signal.

Did you try connecting directly to the new monitor?
Different cables?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Ok, got my old computer working now, connected it to old monitor direct and worked then when it was on put int he KVM switch and is working fine.  

On this other computer which was the one I first couldn;t get working, I see another port on it, that migt be for video so is there a chance the VGA is disabled?
Is that port a video port in the image?

The top one looks like a DVI video port.
The bottom one (with only 2 rows of holes) is a Joystick port.

Is there different types of dvi port? There is one on my new monitor and a cable came with it but it definately doesn't fit into that port. Would the vga be disabled on the desktop? Its one on the main motherboard rather than a card.

>> Is there different types of dvi port?

Not that I know of. And you are right, THAT isn't DVI.
I'm not sure what that is, but it doesn't match any that I see:

There was something that was suppose to take the place of HDMI, but I haven't heard anything about it recently. I will look through some of my mags and see if I can find it.

>> Would the vga be disabled on the desktop

It might be. But about the only way to test, is to Clear the CMOS and see if it Enables it again.
You might think about cracking open the case, pulling that card, and seeing what it is.

If you have another video card floating around (that matches that systems slots) you could check using it (even an old PCI card)

Bingo! It's a DualDVI port:

Forgot:
If you pull that addin card, some bios automatically turn the onboard video back on, so you don't need to Clear the CMOS.

No problem, must check it when I get back.  I was at the house so not sure what type of connection the monitor had there as I just unplugged everything and took it with me.

I pulled that other card out and booted up again with the VGA plugged in and it worked, although with no graphics drivers but it was enough for me to clean the infections.  
Will plug the card back in to give back to client.  I assume it will just default back to the DVI card.  
Thanks for the help.
