Please provide the model number of your Dell and the inputs your monitors support, then we can be more specific.
As a long time dual-monitor user, I can say this. Your best solution may be to get a new graphics card that supports your monitors directly, without adapters (except perhaps DVI to HDMI - since the digital video protocols in both are identical). If you don't game, then you don't need to spend a lot, and may not need to upgrade the PSU.
Note in today's graphics oriented world, assuming an ample supply of RAM (at least 2Gb), upgrading the graphics solution can yield a significant over all performance boost for your computer. Next to bumping up RAM, a new graphics card typically gives the best bang in terms of performance gains for the money. So you might consider "investing" in a new card, one with the necessary graphics ports to support your current and future needs. The downside is graphics cards can be very power hungry - often the most demanding device inside the computer, at least for high-end cards. And many cards require additional power connections.
If like me, once you get used to running with 2 monitors, you will wonder how you lived with just one. That said, while Windows (XP and newer) supports multi-monitors, not all programs do and so having a multi-monitor utility is almost a necessity. My favorite is UltraMon – not free, but worth it. Others have suggested the free DisplayFusion, but I have no experience with it.

I am reminded of my grandkids sitting in the back seat of the car and asking, "what is that?"
yes, that is what I have on the back of my Comp
I referenced two totally different 9-pin connections - you did not say which one - and I don't what "that" is.

Did you look in your manual? Note on page 167 it clearly shows that 9-pin is the serial port.
Finally, that is not a dual monitor logo. That is an image depicting a "series" of 1s and 0s - thus indicating a "serial" port.

So, it looks like you need a new card if you want to use dual monitors - unless that computer has an added card - I suspect not.
