It is not hard at all. If you are using a laptop check if it has the port to connect to another monitor and check if your video card will run two monitors . Choose Control Panel, choose Display, then choose Setting s and see if there are two blocks visible which means your video card is set up properly then if it is you can connect a second monitor. After connecting the second monitor, got to the Control Panel, Choose Display, then choose Settings, click 2 to activate the second monitor, then click the check box that shows Extend my Windows desktop into this monitor and click OK.
