Maybe your graphics card does not support two DVI-D ports that can be used simultaneously. On one of my laptops, I got two monitors working by connecting one via DVI-D and the other via VGA. In any case, check the specs on the graphics card. Regards, Joe

Is the Acer toggled to the DVI input?
Does it need a DVI dual-link or DVI-I cable to work?

What happens if you swap the Acer to the working cable and the HP to this cable?

Well, how do you do it? Just connect and wait? You will often have to manually extend/clone the screen using the screen resolution control panel item that you can start using rightclick desktop - screen resolution.

Actually, I have only one VGA from my pc. Do I need a spliter for this? What kind would I need? Both of my monitors have both VGA and DVI on each one.

Now I'm confused. You first post said:
I am trying to connect a second monitor and keep getting "cable not connect".
My first thought when I read this is that two cables are going from two video ports on the computer (either one VGA and one DVI-D or two DVI-D) to the two monitors (one VGA cable to the VGA port on one of the monitors and one DVI-D cable to the DVI-D port on the other monitor; or two DVD-D cables to the DVI-D port on each of the monitors). But your last post said this:
Actually, I have only one VGA from my pc.
So now I'm thinking that your computer has only one video port, not two. If so, that's a whole different situation.

Please clear this up. How many video ports are on your computer and what type(s) are they? Regards, Joe

If you want to have the same display on both monitors (i.e., duplicate/clone the screen), then you'll need a VGA splitter (single male to two females) and two standard VGA cables. Here are examples of such splitters:

http://www.amazon.com/StarTech-com-VGASPL1VV-1-Feet-Video-Splitter/dp/B003AVPV1O/

If you want an extended desktop configuration, then you need to get a second video card for your computer...or replace the current card with a video card that has two ports. If you get a new card, I would recommend getting one with two DVI-D ports, since both of your monitors support DVI-D and that would likely provide a better quality display than VGA.

If your computer is a laptop, or if it's a desktop but you don't want to open it up, then you could go with a USB-to-VGA or USB-to-DVI video adapter, something like this:
http://www.amazon.com/StarTech-External-Video-Monitor-Adapter/dp/B005G306I2/

Once again, I'd recommend the USB-to-DVI model (although it's a little more expensive than the USB-to-VGA one), since it would likely provide a better quality display than VGA. Regards, Joe

I agree.

VGA Y-splitter if you are just Cloning them.
USB video w/vga would be the quickest and easiest to get going, to Extend them.
USB video w/dvi would be better. But there are 3 different flavors of DVI, so you need to make sure the monitor DVI Inputs, your DVI cables, and the USB DVI video Output(s), are compatible.

Seems to me that the OP can't follow McKnife's advice because he doesn't have both monitors connected to the PC...as I understand it now, the problem is connecting both monitors to the PC. Once that happens, then McKnife's advice kicks in...at that point, the two monitors may be configured as clones of each other or in an extended desktop setup. Regards, Joe

Ok, I see, right. No second output port but vga? That's rare nowadays. What GeForce card does feature only one output port? Seems to be a laptop, right?
Please tell us what laptop because I did not succeed googling your GeForce card.

You're welcome. Congrats on the new PC! Make sure its video card has dual ports, ideally DVI-D, since both of your monitors have DVI-D, although most modern PCs have DisplayPort and/or HDMI ports, in which case you can get adapters or cables to support your DVI-D monitors. Regards, Joe
