The Philips Power Sensor LED display using 65% post consumer recycled plastics & PVC, BFR free housing is ideal for eco-friendly productivity. Power Sensor is a built-in people sensor that transmits & receives harmless infrared signals to determine if user is present & automatically reduces monitor brightness when user steps away from the desk, cutting energy costs by up to 80 percent & prolonging monitor life. The Philips monitor, thanks to its advanced Smart Ergo Base, can be lowered down almost to desk level for a comfortable viewing angle. Low bezel-to-table height is the perfect solution if you use bifocals, trifocals or progressive lens glasses for your computing work. in addition, it allows for users with greatly different heights to use the monitor in their preferred angle & height settings, helping them reduce fatigue & strain.
