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.



VESA mount compliance means you can easily mount the LFD to any mounting that complies with the VESA standard.



IPS 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.



LAN control enables making adjustments in the display OSD menu through your network (software not included).






24/7 displays are designed for a continuous operation.
