Help in buying new Desktop Monitor

I want to buy a new monitor and looking and thinking to buy Dell E2014H. What are the specifications of this monitor? How much is it? What are the features of this monitor? What do you mean by color Gamut? What is its functions? What do you mean EPEAT? What is the purpose of this and why will I consider this in buying new monitors? What will be the power consumption of this monitor? What about the brightness and clarity?
Please provide me feedback and will be appreciated. Thank you!
