PBP (PICTURE-BY-PICTURE)
The PbP (picture-by-picture) function allows for simultaneous display of content from up to four different signal inputs. Divided into four, the screen offers users a workplace equal to four Full HD displays put together without the bezel getting in your view and saving you the hassle with extra cables. It’s perfect for a huge range of applications like stock market data, medical desktop publishing, CAD/CAM drawings, graphic and web design.
4K
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.
FLICKER-FREE + BLUE LIGHT
The ultimate solution for the comfort and health of your eyes. Flicker-free monitors with the blue light reducer function substantially reduce the strain and fatigue caused by flickering and blue light emittance of regular monitors.
VA MATRIX
VA panel 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.
SPEAKERS
This LED monitor is equipped with two high quality stereo speakers.
