In the course of my website design work I need to meet my customers and present my proposals for discussion.
This type of meeting would obviously benefit from a second screen for my customers to view, rather than us both trying to look at the typical laptop screen with its narrow viewing angle.
Carrying around a bulky monitor or having to book a meeting room with a projector and/or screen is not really practical so I searched for an alternative and eventually came across a lightweight LED screen offered by ASUS. It comes with its own carry case which doubles as a stand and it plugs into a USB port.
Between times it can be used as an extended display which is also useful in your design work or on an exhibition stand for displaying presentations.
