    Experience the bigger picture - 4K resolution, where every detail comes to life!

    iiyama 4k displays


    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.

    Protect your eyes, and enhance your view - flicker-free and blue light, the perfect duo! 


    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.

    Deeper blacks, brighter whites, and perfect viewing angles, every time!

    VA panel technology

    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.

    Clarity is key - listen up!
