ViewSonic VG939SM - LED monitor - 19"

It has fully ergonomic 19'' (19'' viewable), 5:4-ratio LED display with Flicker-free, Blue Light Filter and ViewMode technologies for more comfortable day-to-day use. SuperClear technology (IPS panel) for superior 178°/178°wide-angle viewing, and 20M: 1 DCR, dual stereo speakers, DVI and D-Sub inputs together deliver superior high-quality color and sound performance. Plus, the VG939Sm has an energy-saving ECO mode and ENERGY STAR compliance, with a VESA-compliant 100mm x 100mm mount for greater installation flexibility. With a standard 5:4 aspect ratio and 1280x1024 resolution, this display is ideal for business-specific legacy applications. In addition, with a square compact shape, the VG939Sm can also be used as a countertop display in public environments with space constraints.

ViewSonic flicker-free displays deliver on the promise of more comfortable viewing. 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. This lets you work at your computer, play games, or watch movies longer - without eye fatigue.
