At present, the labs only have single screens and a lot of the time it is necessary to have multiple documents/windows open at once - for example a lab manual and virtual machine. Dual screens would be more much useful for productivity and comfort as we would be able view more than one document/window at any one time without having to keep flicking between different windows every five seconds! Elsewhere in the university rooms exist with dual-screen computers and the benefit of a second screen is definitely noticeable and appreciated! For those of us who use the labs on a regular basis, a second screen would make life and learning an awful lot easier!!!
