1) You have to have a graphics card with two monitor ports.
You Cannot use one port on a graphics card, and the VGA, or DVI port on the motherboard of the computer.
BIOS will only let you use the graphics card, or the Integrated Graphics.
2) Using a 'splitter' cable results in very bad graphics on two monitors, or no graphics at all.
3) With a graphics card installed that has two monitor ports on it, connect the monitors to the graphics card.
[ The graphics card can have a VGA port, and a DVI port. Or the graphics card can have two DVI ports.

4) Turn the two monitors on once they are connected to the graphics card.
Turn on the computer.
5) Windows loaded, right-click on an empty area of the desktop screen.
6) In the list go to the bottom, and click on Properties
7) Click on the Settings tab.
8) You will see two monitor icons.
One icon has a square with a 1 in it.
The other icon has a square with a 2 in it.
The 1 monitor icon is used to represent your Primary monitor.
The one you have been using.
As you can see the 1 monitor icon is sitting to the Left.
This is how your Primary monitor should be sitting on your computer desk.
The 2 monitor icon is used to represent your Secondary monitor.
The one you are going to add.
As you can see the 2 monitor icon is sitting to the Right.
This is how your Secondary monitor should be sitting on your computer desk.
Left-click on the 2 monitor icon.
Go below in the Display Properties window, and view where it states -
Extend my Windows desktop onto this monitor
There is an empty square to the left of it.
Left-click in the empty square.
Now go below to the Right, and click on - Apply
Finally go below to the Left, and click on - OK
Your desktop screen will now be on your Secondary monitor.
Whatever is on your Primary monitor, has to be drug over to the Secondary monitor, when you are on the internet, or a program. (Such as a game)
Go to the blue frame on the Left side of the Windows screen.
When your cursor turns into a double-headed arrow STOP.
You'll find it's a little tricky your first time, keeping your cursor into the position where it turns into a double-headed arrow.
With the cursor in a double-headed arrow, press the left mouse button down, hold it down.
Drag the monitor screen to the Left.
Keep dragging until the window on your Primary monitor is on your Secondary monitor.
It's helpful you'll find to have two of the same size monitors.
I have found occasion where when using the internet on two monitors, that I had to Restore Down the screen, THEN drag it over to the Secondary monitor screen.
(Icons at the top right of the monitor screen.
Minimize ( - ), .......Restore Down/Maximize, ...........Red X
Then I Maximized the screen
