19” Ergonomic 5:4 LED Multimedia Display
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.

SuperClear Image Enhancement Technology delivers the best color performance and extends display viewing angles to 178 degrees both horizontally and vertically. Experience accurate and vivid colors with consistent levels of brightness whether looking at the screen from above, below, the front, or the side—with no color distortion or decay.

With advanced ergonomic features, ViewSonic displays are designed to provide a greater range of adjustment for increased productivity and comfort. Users can reduce eyestrain and physical fatigue by adjusting the monitor via 360-degree swivel, 90-degree pivot, -5 to 25-degree tilt, and 100mm height adjust options.

Dynamic contrast ratio detects the brightness of an image, and automatically adjusts the backlight to maximize the monitor’s color range and contrast. Dynamic contrast ratio technology enables the accurate reproduction of images, producing vibrant and rich visual effects.

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.

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.

Enjoy excellent performance and accurate color rendering for everything you view on this display. With 5 different scenario presets, ViewSonic displays offer best-in-class calibration techniques to bring you the best digital viewing experience. This includes Game, Movie, Web, Text, and Mono presets to enhance black levels in games and movies, color luster for online images, and color temperature for reading text.

The ViewSonic VG939Sm has two integrated 2W stereo speakers for enhanced multimedia performance with crystal-clear stereo sound.

Planet-friendly mercury-free LED backlighting click to collapse contents

LED backlighting enhances display performance, delivers an outstanding color range, and adjusts contrast ratios for remarkably detailed images. ViewSonic's eco-friendly, mercury-free LED backlighting further conserves up to 25%* more energy when compared to conventional displays. In addition, LED backlighting provides for a slim, lightweight profile that saves desktop space.

ViewSonic’s proprietary Eco-mode feature is built into all LED displays, offering options to select ʺOptimize(75%)ʺ or ʺConserve (50%)ʺ settings that save up to 25% power. Especially in low ambient light, Eco-mode adjusts brightness and improves visibility, while reducing eye fatigue and prolonging the display's lamp life. With Eco-mode, both lamp replacement and energy expenditures are reduced.
