LED backlighting offers significant advantages over the CCFL technology used in older LCD monitors. These advantages encompass not only performance metrics such as higher dynamic contrast, no light leakage & flicker-free, but also environmental factors, like a manufacturing process & disposal that produces fewer pollutants. The GL2250M comes with an ultra-high dynamic contrast ratio of 12M:1 to add color depth & definition to darkened & complex motion pictures, so that everything you see, from the brightest white to the darkest black, is perfectly rendered to deliver the clearest, smoothest picture performance during movies & video games.
