sleek design with a nice looking stand and minimal bezel

The Samsung S27A550H is a high-end 27" LED-backlit LCD computer monitor with a native 1920 x 1080 resolution. It features a 2ms response time, Samsung's Mega Dynamic Contrast Ratio technology and an Eco Motion Sensor. Additionally, the S27A550H sports Magic Angle technology as well as both HDMI and VGA video input options.

The S27A550H's 2ms response time allows it to handle fast-moving media with no ghosting or blurring for a very smooth, clear picture at all times. Its Mega Dynamic Contrast Ratio enhances the S27A550H's static 1,000:1 contrast ratio by way of localized backlight dimming, resulting in extremely deep blacks and bright whites. Meanwhile, the S27A550H's Eco Motion Sensor utilizes a Pyrolectric Infrared Ray sensor to detect movement directly in front of the monitor, turning the monitor on automatically when a person approaches and turning off again when no movement is detected for a short period of time.
