Dell has introduced a new range of ultra-slim desktop monitors. Both the 21.5-inch S2230MX and the 23-inch S2330MX are just 9.9mm at their thinnest point. Both LED displays support 1080p at 1920x1080 pixels each, and are capable of displaying an 82 percent color gamut for accurate color reproduction. They also have a super high contrast ratio of 8,000,000:1 for brighter whites and better black reproduction.
