  • 43" large format desktop monitor with 4K resolution, giving you the power of four displays in one
    Designed for professionals who need more screen space, the ProLite X4373UHSU offers a seamless solution for multitasking and multi-device workflows. The 43'' panel delivers rich colours, sharp 3840x2160 resolution and wide 178° viewing angles, with 450cd/m² brightness ensuring excellent visibility in any lighting. For added flexibility, the monitor supports dual mode, allowing you to work in 3840×2160 for detailed content creation and data-heavy applications, or switch to 1920×1080 at 120Hz for smoother motion when displaying dynamic content or live feeds.
    The USB-C input with 95W Power Delivery, integrated KVM switch and four-port USB hub make it easy to connect, control and charge multiple devices through a single setup. Flicker-free technology and a blue light reducer help minimise eye strain during long sessions, while the included remote control offers instant access to key settings.
    Ideal for content creation, financial dashboards or control environments, this all-in-one monitor maximises clarity, comfort and productivity.

    Adapt your display to match your pace
    Switch seamlessly between two optimised modes to suit the task at hand. Dual Mode empowers your workflow by offering crystal-clear 4K resolution for precise data work, or a responsive 120Hz Full HD setting for smooth motion during live feeds and dynamic content. One screen with two smart ways to stay productive, without compromise

    Deeper blacks and richer detail with VA panel
    The VA panel offers exceptional contrast and deep blacks, revealing every nuance between light and dark. Enjoy vivid, lifelike images with minimal light bleed and excellent color depth, especially in darker scenes. Whether watching movies, editing content, or gaming, benefit from consistent picture quality and wide viewing angles that bring every detail to life.

    Easy multi-device control with KVM
    Easily switch between multiple computers using one monitor, keyboard, and mouse, making multitasking smooth and efficient.

    Built-in audio without extra clutter
    Enjoy clear, pleasant sound for calls, videos, and music while keeping your desk free of extra speakers, thanks to the integrated audio.

    Double the view, double efficiency
    Watch two sources at once. Use Picture-in-Picture to overlay a second feed or Picture-by-Picture to split the screen side by side. Perfect for multitasking, comparing content, or staying in control.

    Reduced eye strain & fatigue
    Work, study or play longer without eye fatigue, thanks to flicker-free technology and reduced blue light emissions. These features help minimize eye strain and improve visual comfort, allowing you to stay focused and productive throughout the day.
