if you open the display manager, there should be an option to mirror displays. turn this off.

Doesn't your graphics card have two individual DVI inputs for the monitors?

Quote HistoryQuoted: Better video card. $75 Txl This. Dell has a habit of building boxes to a price-point - if the box is not advertised as specifically supporting 2 monitors, it will not. On the other hand, Dell is usually very good at providing all the proper cables. Again, if it didn't include the proper cable(s) guess what? As TxL suggested, you probably need a better video card, rather than the basic on-board video that Dell built onto the motherboard. Make sure that the video card you get will support the 2 monitors that you have - correct number and types of ports. Typically you will have to disable the on-board video, in the BIOS, and run both monitors off the new video card. Good luck - getting it all going may include ice cubes and suitable beverage. |

There needs to be two separate display outputs.
A splitter simply splits the signal. It can't do anything but mirror the displays. Post a picture of the ports in the back. Quote HistoryQuote HistoryQuoted:

I video splitter is going to do just that... split the SAME signal to both monitors.
You need either a second port on the video card (which you obviously dont have), a better video card that includes 2 distinct ports (assuming your video card CAN be changed) or you can buy something like a USB video adapter. Something cheap like this will work if you are only doing basic stuff: You may have to buy a nicer one if you want to use high resolutions or do anything advanced with it. I use the EVGA one to drive a 24" monitor (as a 3rd monitor) off my macbook at work: Also on a side note, can somebody tell me what I am doing wrong with the damn links?!?! I know you can post a whole link as a word, but the link editor thing is drivnig me nuts and I dont have patience to figure it out right now....

A dual output DVI interface on a Dell does not look like a normal DVI port and ships with the correct adapter. A third party splitter doesn't split, it's a duplicator.

No need. I just went in there and triple checked that I was not overlooking another video out port. There is only the single, standard, VGA monitor port. Looks like I will be upgrading the video card to add the support needed. TRG |

I bought a cheap USB to VGA adapter for my second monitor and it works great. I think it was $30 at BB.
You can stack them too if you run more than 2 monitors(thinking of adding a third on my home PC) |

Is there a Dell Display port on the motherboard? Will look like either an HDMI port or a microUSB port on steroids. If so, then then make sure it's enabled in the BIOS and you have a mini display port cable:
