Ambiglow Intensifies Entertainment With Halo of Light
Ambiglow adds a new dimension to your viewing experience. The innovative Ambiglow technology enlarges the screen by creating a halo of light on the surrounding wall from the rear of the monitor. Its fast processor analyzes the incoming image content and continuously adapts the color and brightness of the emitted light to match the image. Friendly options allow you to adjust the ambiance to your liking and also helps reduce eye fatigue. Especially suited for watching movies and sports, or playing 2D or 3D games, Philips Ambiglow offers you a unique and immersive viewing experience.
AH-IPS LED Gives Brilliant Images With Vivid Colors
This latest Philips display uses advanced AH-IPS panels utilizing improved structure resulting in superior color reproduction, response time and power consumption as compared to other wide view angle panels. Unlike standard TN panels, AH-IPS panels exhibit the least amount of Gamma fluctuation and therefore are able to show consistent color even at a 178 degree viewing angle or in pivot mode. With remarkable performance, it's best suited for applications demanding color accuracy and consistent brightness at all times. Enjoy great performance for projects like photo retouching, graphics applications and web browsing.
Minimalistic Appearance with an Ultra Narrow Bezel
Utilizing the latest technology panels, the new Philips displays are designed with a minimalistic approach by limiting the outer bezel thickness to about 2.5mm. Combined with in-panel black matrix strip of around 9mm, the overall bezel dimensions are reduced significantly allowing for minimal distractions and maximum viewing size. Especially suited for multi-display or tiling setup like gaming, graphics design and professional applications, the Ultra Narrow Bezel display gives you the feeling of using one large display.
HDMI Ensures Uiversal Digital Connectivity
A HDMI-ready device has all the required hardware to accept High-Definition Multimedia Interface (HDMI) input, high quality digital video and audio signals all transmitted over a single cable from a PC or any number of AV sources including set-top boxes, DVD players and A/V receivers and video cameras.
SmartImage: Optimized User Friendly Display Experience
SmartImage is an exclusive leading edge Philips technology that analyzes the content displayed on your screen and gives you optimized display performance. This user friendly interface allows you to select various modes like Office, Image, Entertainment, Economy, etc., to fit the application in use. Based on the selection, SmartImage dynamically optimizes the contrast, color saturation and sharpness of images and videos for ultimate display performance, while Economy mode offers major power savings. All of this happens in real time with the press of a single button!
SmartKolor for Rich Vibrant Images
SmartKolor is a sophisticated color extension technology that is able to enhance the visual color range of the display. By boosting RGB gain level of the display, this feature enables you to have rich, vibrant images for experiencing outstanding photos and videos.
SmartTxt for an Optimized Reading Experience
SmartTxt is a sophisticated algorithm that enhances your reading of text based applications such as PDF documents or ebooks, usually requiring more focus and concentration. SmartTxt feature increases the contrast and boundary sharpness of text content for better readability. Optimization for reading is done by adjusting the display's gray level scale along with the white balance, brightness and contrast.
Smart Bias 6500K Lighting Ensures an Optimum Viewing Experience
Smart Bias lighting mode enables you to enjoy vivid image quality with optimum viewing comfort. In a dark room, your eyes dilate and constrict with the constantly changing images which may lead to Computer Vision Syndrome. Smart Bias light creates a soft halo of static 6500k white light on the surrounding wall around the monitor. Especially suited for people who spend extended time on their display, it not only helps reduce eye strain and fatigue, but also eliminates reflections and glares from room lighting, enhancing perceived contrast ratio and picture details and preserving correct color perception.
