IdeaCentre B540

Described as the "bigger brother" of the B340, the B540 offered a 23-inch widescreen display. Like the B340, this all-in-one also offered a 1080p HD touch screen, Intel processors, NVIDIA discrete graphics, and similar specifications for both storage capacity and memory. A difference between the two was that the B540 had a frameless screen, with the glass surface extending from one edge of the display to the other. Another difference was the discrete graphics offering. The B540 could be equipped with an NVIDIA GeForce GT 650M, with up to 2GB of video RAM.
