Dell 27 inch Ultrasharp

This monitor features quad HD (QHD) resolution (aka screen real estate for all your documents/terminals/youtube/chrome tabs). The dell ultrasharps are also great for accurate color reproduction if you like any sort of design work (/photography/etc.). This model in particular is the U2713H, which also features 10 bit color (vs the standard 8 bit) and an SD reader built in to the monitor.
