It is pretty easy. All you have to do is attach 1 plastic piece to the base and then set the monitor into the base. It comes with a VGA cable if you plan to use that, but if you want to attach it to the computer via a DVI cable you will need to have your own or buy one.
I would recommend attaching whatever cable (VGA or DVI) you are planning on using in addition to the power cable prior to setting the monitor up on its base, otherwise it may be a little difficult to access the connector area.
In most cases, the term "VGA" refers to the type of cable used to carry the display signals, regardless of the actual graphics system being used. It's characterized by 15 pins on the plug in three rows of five. The plug also has two screws, one either side of the pins, that secure it into place in the socket. These screws have ridged edges, meaning they can be tightened and loosened by hand rather than needing a screwdriver.
When I bought my Mac Book Pro,I also bought at that time a 6 inch long HDMI/DVI Cable.I connected my MacBookPro this Cable and then connected the Cable which was sent to me with my purchase of ViewSonicVA2446.Amazon reccomended a 9 feet long HDMI cable which I could not connect with my LapTop.Inquire from Apple for this 6 inch HDMI/DVI cable.
Strange ! I see three previous answers and each one is different - and different from my measures. They either have different models of monitor or different stands ( one does ). Holding a 18" ruler against my monitor the top of the monitor including stand is 15 3/4" from my desk top. Without the stand it is 13 3/4", but what good is it without a stand?
