The 24in flatscreen display has a resolution of 1,920x1,200 WUXGA and offers "edge-to-edge 1080p HD viewing", while a JBL speaker set makes the most of the audio.

A Product(RED) version of the XPS ONE 24 is also available, with $50 from each machine sold going to fund HIV and AIDS research in Africa.
