ViewMode: Superior Color Rendering & Intuitive Settings

ViewSonic’s unique ViewMode feature offers “Game,” “Movie,” “Web,” “Text,” and “Mono” presets. These presets enhance gamma curve, color temperature, contrast, and brightness to deliver an optimized viewing experience for different screen applications.

ViewSonic Flicker-Free viewing for improved eye comfort

ViewSonic flicker-free displays deliver on the promise of more comfortable viewing. ViewSonic flicker-free technology nearly eliminates 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. Care for your eyes with ViewSonic flicker-free technology!

Blue light filter for more comfortable viewing

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. It offers 100 levels of blue light filtering to relax users’ eyes and adapt to all your daily digital activities.

Eco-mode Conserves More Energy and Cuts Costs

ViewSonic’s proprietary Eco-mode energy-saving feature is built into all ViewSonic LED monitors. Eco-mode adjusts brightness and improves visibility, while reducing eye fatigue and prolonging the monitor’s lamp life. With Eco-mode, the lifespan of the LED backlighting is also greatly increased.

VESA-Compatible Mount Design
