The 50-series of attractive, slim monitors features with clean styling & LED technology, priced to appeal to value-conscious consumers. LED backlights contain no toxic mercury (Hg) to contaminate the environment, & offer substantially lower power consumption than traditional monitors, further reduced with user-selectable power-saving display modes & switch-off timer. Although e 2050 Sda presents simple monitors with a focus on value, AOC has not skimped on display dynamics, with a vivid contrast ratio of 20, 000, 000:1 DCR ensuring clear visibility & vibrant images. Outwardly, the 50-series monitors do not look at all cheap, with a slim & rounded design that tapers to just 18 mm at the top & sides. The back of the cabinet & top surface of the base feature a luxurious brushed texture. Control buttons are discreetly recessed underneath the shiny-edged screen bezel. Digital connector & speakers are more convenient for families.
