Power Sensor saves up to 70% energy costs Power Sensor is a built-in 'people sensor' that transmits & receives harmless infrared signals to determine if the user is present & automatically reduces monitor brightness when the user steps away from the desk cutting energy costs by up to 70 percent & prolonging monitor life. Light Sensor for the perfect brightness with minimal power Light Sensor uses a smart sensor to adjust the picture brightness depending on the light conditions in the room for the perfect picture with minimal power usage. IPS technology for full colours & wide viewing angles IPS displays use advanced technology that gives you extra-wide viewing angles of 178/178 degrees making it possible to view the display from almost any angle — even in 90-degree Pivot mode! Unlike standard TN panels IPS displays gives you remarkably crisp images with vivid colours making it ideal not only for Photos films & web browsing but also for professional applications that demand colour accuracy & consistent brightness at all times..
