If Both monitors are VGA (the trapazoid shape) then u will need a DVI-VGA adapter, you can pick one up for usually under $10... now to work out where to plug them in::
-Follow cable u see on back of screen that goes to computator
-it will lead into the back of a horizontal adaptor thing,
-You will have at least 1 free, it may look like a Rectangle shape if its A DVI port
-If its Rectangle Shape, and your plug for your 2nd screen isn a rectangle shape then your going to need a DVI-VGA adapter.
-Turn Off Computer
-plug each screen into a port on that horzontal card thing first screen is plugged into
-Turn On computer
- Right click dectop, go to "settings" Tab
- Click the screen number 2
- choose either "use this as primary" or "extend my windowz desctop onto ...."
-Enjoy, If U want more help, email me at
