Know before you buy
Yes. The 38-inch ultrawide 21:9 aspect ratio provides enough horizontal screen real estate to comfortably display two full-sized windows side-by-side, effectively eliminating the physical bezel gap found in traditional dual-monitor configurations.
The integrated USB-C hub allows you to connect your laptop with a single cable that handles video, data, and up to 90W of power delivery. This means you can charge your laptop and connect your peripherals through the monitor without needing a separate docking station.
Yes, the monitor features built-in KVM functionality. This allows you to connect two different computers to the display and control both using a single keyboard and mouse set, while the Picture-by-Picture mode lets you view both sources simultaneously.
It is well-suited for most professional tasks, as it offers 95% DCI-P3 color coverage and is factory-calibrated to a Delta E of less than 2. While it provides excellent color accuracy for design and office work, specialized color-critical workflows may still require a dedicated professional-grade display.
The 2300R curvature is relatively subtle, designed to improve viewing comfort and reduce eye strain by keeping the edges of the screen at a more consistent distance from your eyes. Most users find it enhances immersion for productivity without causing noticeable image distortion.
Yes, it includes ComfortView Plus, which is a built-in, always-on screen technology that reduces harmful blue light emissions. It achieves this without sacrificing color accuracy, making it a great choice for long work sessions.
