Excerpt: With the advent of LED backlighting comes the obsession with creating the thinnest possible monitor. LG claims the W2486L is the world’s thinnest 24in PC monitor, but it’s a dubious honour. In fact, the W2486L’s thinness creates more problems than advantages. One is the external power supply. Instead of a built-in power supply as most monitors have, LG has had to bundle a large black box with the W2486L as there was no room for it inside the casing.
