AMVA3 technology offers higher contrast, darker blacks and much better viewing angles than standard TN technology. The screen will look good no matter what angle you look at it.
UHD resolution (3840x2160), better known as 4K, offers a gigantic viewable area with 4 times more information and work space than a Full HD screen. Due to the high DPI (dots per inch), it displays an incredibly sharp and crisp image.
DisplayPort/HDMI daisy chain support
A daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring. It enables a connection of a series of devices using a single connection between each two devices, using DisplayPort/HDMI input and a DisplayPort/HDMI output. The output connects to the next downstream display. This cabling arrangement, with one DisplayPort/HDMI cable between each set of monitors, provides a simple, less cluttered system configuration.
The ambient light sensor detects changes in environmental lighting conditions and automatically adjusts the screens backlight brightness to compensate for an increase or decrease in light.
