I know that some people prefer to use dual/triple/quadruple displays and others prefer a one screen solution. I am currently using a Dell 27" LCD @ 1920 x1200 and an Acer 23" @ 1920 x 1080.

I am getting more and more unhappy with the 27" Dell display simple because it pumps out a shitload of heat. I was thinking perhaps LED would run cooler but was looking for peoples thoughts.

Does anyone have any suggestions and what kind of displays do you use in your setup?
