Product features

Experience clarity, productivity and connectivity on this 37.5" ultra-wide WQHD+ curved hub monitor with 95% DCI-P3 color and integrated speakers.

  • More screen to captivate you
    See all of your work and multitask like you've always wanted with more onscreen space on this 37.5-inch ultra-wide WQHD+ (3840 x 1600) curved screen. And with a vertical height of 1600 pixels, you can see more and scroll less.
  • View that draws you in
    The 2300R curved screen creates a wider field of view, minimizes reflection and offers near-uniform visual focus, for a comfortable, panoramic, wrap-around view.
  • Consistent, vibrant colors
    Expect consistent color and picture quality across a wide viewing angle, thanks to IPS technology. See true-to-life color with an incredible color depth of 1.07 billion colors and wide color coverage across industry standards, including 95% DCI-P3.
  • Accurate color, out of the box
    Your monitor is factory-calibrated for accurate colors right from the start.
  • All-encompassing sound
    Integrated dual 9W speakers deliver quality sound for an auditory experience that pulls you in even further.
  • Connect to productivity
    With RJ45 and USB-C, your monitor serves as a productivity hub that delivers stable Ethernet and up to 90W of power delivery - all in a clutter-free setup.
  • Extensive connectivity
    Easily connect to a variety of devices with a wide range of connectivity options, including DP1.4, HDMI, and USB-C: a single-cable solution that transmits data and video while delivering up to 90W of power to charge a wide range of laptops. Plus, quick-access USB-C and super speed USB ports conveniently located at the front enable fast connection to peripherals, such as storage devices and mobile phones, with a charging capability of up to 15W (via USB-C).
  • Multitask efficiently
    Connect two PC sources to the monitor - intelligent auto KVM feature detects the second connected PC and seamlessly switches controls over. View content from both PC sources with Picture-by-Picture (PbP) and Picture-in-Picture (PiP). The KVM (keyboard, video, and mouse) feature allows you to control both PCs with a single keyboard and mouse.
  • Beauty meets function
    Crafted with a premium platinum silver finish, this sleek monitor features a streamlined design that runs the cables through the monitor riser for a clutter-free setup. Plus, you can navigate the menu and adjust screen settings with the easy-to-use joystick control.
  • Comfort is key
    Tilt, swivel, and adjust the height of your monitor because you should be comfortable however and wherever you work.
  • Easy on the eyes
    Optimize eye comfort with a flicker-free screen and ComfortView, a feature that reduces harmful blue light emissions.
  • Productive at every level
    Easy Arrange allows you to easily tile multiple applications across one or more screens with 38 pre-set window partitions and the ability to personalize up to five windows, giving you improved multitasking abilities.
  • Seamless transitions
    The auto-restore feature remembers where you left off, so applications will go back to where you left them, even after you've unplugged.
  • More ways to manage
    Asset management reports allow IT managers to quickly capture and track monitor information as well as configure multiple monitors at once through a single setup.
  • Key to convenience
    Shortcut keys can save you even more time, letting you easily configure your display management settings so you can get to work faster.
  • Energy conservation
    Save energy when your monitor is not in use with PowerNap, a feature that dims or puts your monitor to sleep when it's not in use.
