My work utilizes a basic VGA Y split cable, a 20 inch monitor and an 16 inch monitor. The small monitor is the desktop extension with no task bar. I know it's possible without dual video cards... somebody has to know how.

if your graphics card has multiple output ports then it is easily capable of handling dual monitors.

Most motherboards today have both a VGA and DVI port as well, and most integrated graphics chips also support dual monitors. It's just a matter of plugging in multiple monitors.

split cable don't extend the screen, it duplicate the same screen to 2 monitor.

So i'm running windows 8 on a much nicer set up than work runs and I have a VGA split, but it won't let me extend my desktop it only duplicates! I can't get it to register the secondary monitor as monitor #2 they both identify as #1. any suggestions?-- Also, my current computer does not have DVI capablitys only VGA and its only 1 pre-out.

it depends on the graphics card present in the PC. I have some workstations at work that have split cables with extended desktops.

I highly doubt its a standard VGA splitter. It's most likely a DMS-59 to dual vga adapter(http://en.wikipedia.org/wiki/DMS-59) which will look similar to a vga splitter but support dual monitors in extended desktop mode. A standard VGA splitter would just clone the displays. Most video cards now a days supports atleast 2 monitors.

Do you have any suggestions on how to use a Y splitter to extend a desktop? I know it's possible, I can take pictures of the setup at work tonight, and post them.

This is actually the same for my work. Every workstation has a 20 inch and a 16 inch using a Y split cable. I'm trying to get that same setup at home any hints?

It looks like your home computer does not support dual monitors, that's all. If it only has one output port then it probably doesn't support dual outputs.

The Y split they use at work looks very similar to this, but all 3 ends are blue and the same size.

You have a few options.
1. upgrade the video card
2. use a usb to vga or dvi adapter(http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
3. A matrox dual head to go adapter(http://www.matrox.com/graphics/en/products/gxm/dh2go/di...)

So my work setup up is most likely a DVI to VGA split, instead of actually VGA to VGA. Which is also the DMS-59 the gentleman referenced earlier. any ideas on what hardware I could get to run 2 monitors with extended desktop without installing a new Video Card? The computer is still under warranty and I'm fearful of breaking it open.

Odd that a newer system only has 1 video output. Whats the make and model of your computer.

Yep the motherboard only has 1 vga port which is kinda odd in this day and age. If you add a video card It should not void the Dell warranty. You can get a card that will support dual monitors for $30. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

this is intriguing, whilst the VGA connector can carry relatively high resolution (albeit at dubious quality) so that it could potentially have a large horizontal resolution to cover 2 monitors, the signals in the connector shown here;

appear to provide no
