    Iiyama Prolite X4071UHSU-B1 40" 4K Monitor Product Description

    ProLite X4071UHSU-B1

    Stylish 40" screen with 4K resolution and USB hub

    The ProLite X4071UHSU-B1 is an impressive 4K (3840 x 2160) monitor, offering 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) the monitor displays an incredibly sharp and crisp image. The VA panel technology offers exceptional colour performance, high contrast (5000:1) and wide viewing angles. PIP and PBP features allow users to easily create their own work space by displaying and manipulating multiple applications. USB 3.0 HUB, integrated speakers, headphone socket and hook, ensure compatibility across various devices and media platforms for a real multimedia experience. The ProLite X4071UHSU-B1 suits a massive range of applications including desktop publishing, CAD/CAM drawing, gaming, photographic and web design.


    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.


    MVA 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.


    PIP (Picture in Picture) function allows you to watch images coming from two different sources at the same time.

    Blue light reducer

    As we all know looking at a monitor screen for several hours per day, especially form a closer distance, causes eye fatigue. This effect is much stronger with computer screens than with TV equipment. One of the factors responsible for this phenomenon is the blue light emitted by the screen. Therefore reducing the amount of blue light ultimately allows our eyes to feel less tired while working long hours with a computer screen. We achieved it by adjusting the monitor's brightness and color temperature through a new feature called "Blue light reduction" easily accessible through the monitor's OSD menu.
