PBP (PICTURE-BY-PICTURE)

The Picture-by-Picture (PbP) function allows content to be displayed simultaneously from four different signal inputs. Divided into four, the display offers users a workspace equal to four assembled Full HD displays but without a frame or hassle with additional cables. It is perfect for a wide range of applications such as stock or medical data, CAD/CAM drawings, graphic design and web design.

4K

The UHD Resolution (3840 x 2160), better known as 4K, offers you a gigantic display area with 4 times more information and work space than a classic Full HD screen. Due to its high dots per inch (DPI) density, it will display incredibly thin and sharp images.

FLICKER-FREE IMAGE + BLUE LIGHT REDUCTION

The ultimate solution for the comfort and health of your eyes. Flicker-free monitors with the blue light reduction feature significantly reduce the voltage and fatigue caused by flickering and blue light emission of traditional monitors.

VA MATRIX

VA technology offers higher contrast, darker blacks and much better viewing angles than traditional TN technology. The image will look good no matter how far you look at it.

SPEAKERS

This LED monitor is equipped with two quality stereo speakers.
