Rather than using Pulse Width Modulation that continuously turns the LED backlight on and off, ViewSonic flicker-free displays use DC modulation backlights that maintain a steady stream of direct current power—nearly eliminating screen flickering at all brightness levels by providing a constant LED light source. Also, prolonged exposure to certain levels of blue light can cause eye discomfort. ViewSonic displays feature a Blue Light Filter setting that allows users to adjust the amount of blue light emitted from the screen, enabling longer viewing times and increased eye comfort for work and multimedia applications.Flexible, Comfortable, and Sturdy Ergonomic Design with Versatile Mounting OptionsThe adjustable stand of the VSD224 allows the screen to be tilted and adjusted, or rest flat on a desk or table. If adjusting isn’t enough, the VSD224 features a 100 x 100mm VESA-mountable design that allows you to mount the display on a monitor stand or on a wall, depending on your specific needs. You can easily unscrew the base, and then mount the display on its new stand or wall mount.Optical multi-touchTouch capability is truly the big differenciator in all-in-ones, bridging practicality with purpose.
