Designed for business environments, the BenQ BL Series of professional monitors is an essential part of your solutions to minimize total cost of ownership and maximize staff productivity - a win-win decision for the benefits of all. The Flicker-free technology eliminates flickering at all brightness levels and effectively reducing eye fatigue. Conventional LCD screens flicks 200 times per second. Your eyes may not see flickers, but can certainly feel them. Free your eyes from flickers by switching to Flicker-free Monitors and let your eyes do less work. Every Monitor produces a strain of blue spectrum light that is one of the critical causes of eye damage, eye strain, headaches and sleeping disorders. BenQ's unique Low Blue Light technology is designed to deal with the everyday problem of blue light exposure and allows a healthier time spent in front of your computer. Switch to one of the four preset Low Blue Light Modes from OSD hot key (Multimedia - 30% reduction, Web-surfing - 50% reduction, Office - 60% reduction, Reading - 70% reduction), and reward your eyes without having to lose the visual enjoyment.
