Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I like dual monitors over one large. Two 23" monitors have significantly more area than on 27".Make sure you get IPS as they give a wider viewing angle before colors start shifting.I am running dual Dell U2312. U being a higher end model, 23 the size and 21 signifies the 2012 model. They were pretty cheap when I got them. I think 2314 is available, not sure if they updated after that. As a bonus, they come with a USB port and they rotate 90 degrees if needed.pierre
