The ProLite XCB4994DQSU-B1 gives professionals the screen space they need to work more efficiently. Its expansive 49-inch display, 32:9 aspect ratio and 5120 x 1440 Dual QHD resolution provide the workspace of two QHD monitors in one seamless screen. Users can keep multiple applications, documents, dashboards or timelines open side by side without switching between windows or working around central bezels. The 1000R curved VA panel brings the entire workspace into a more natural field of view, making it easier to monitor information across the screen while reducing unnecessary head and eye movement. High contrast, vivid colours, wide viewing angles and 400 cd/m2 brightness keep text, graphics and detailed content clear in bright office environments. A 2ms GTG response time and Adaptive Sync support smooth scrolling, video playback and work with moving content. Flicker-free technology and a blue light reducer help maintain visual comfort during long working sessions. Height and tilt adjustments allow users to create a more comfortable workstation, while the three-side borderless design gives professional setups a clean, modern appearance. Dual HDMI and DisplayPort inputs provide flexible connectivity for multiple devices, and integrated 2 x 5W speakers support video calls, presentations and everyday media without additional desktop equipment. By replacing a dual-monitor setup with one uninterrupted 49-inch workspace, users gain more room to organise their work, compare information and stay focused throughout the day.
