Desktop USB-C Monitor - ProLite XCB4594DQSU-B1 - 45in Curved 1500R - 5120x1440 (DQHD) - Black

Introduction

If you work across multiple windows, manage creative projects or want a more immersive setup, the ProLite XCB4594DQSU-B1 is built to support the way you work. This 45-inch ultra-wide curved monitor features a 32:9 aspect ratio and a Dual QHD resolution of 5120x1440, providing the screen space of two QHD monitors in a single, seamless display. It removes the interruptions of bezels and brings everything together for a smoother, more efficient workflow. The curved VA panel surrounds your field of view with vivid colours, high contrast and wide viewing angles. The gentle 1500R curvature creates a more natural and comfortable viewing experience, helping reduce eye movement and maintain focus. With a brightness of 450?cd/m², your content stays sharp and clear, even in brightly lit environments. A 2ms response time (GTG) and Adaptive Sync support ensure smooth motion for video editing, content scrolling or occasional gaming. Flicker-free technology and a blue light reducer are built in to support eye comfort throughout the day. With a modern three-side borderless design, the XCB4594DQSU-B1 also offers height and tilt adjustments so you can set up your workspace to suit your needs. Dual HDMI and DisplayPort inputs make it easy to connect your devices, while the integrated 2x3W speakers deliver clear audio for video calls, media or presentations. Whether you are editing wide-format content, working with complex data or multitasking across several applications, this ultra-wide monitor gives you the space, clarity and comfort to stay productive.
