Designed for professionals who need an extended display space, the ProLite X4373UHSU is an ideal solution for multitasking and multi-device work environments. Its 43-inch panel offers rich colors, an ultra-sharp resolution of 3840 × 2160, and wide viewing angles of 178°, while its brightness of 450 cd/m² ensures excellent readability in all lighting conditions.
For added flexibility, the monitor supports a dual mode, allowing you to work in 3840 × 2160 for detailed content creation and data-intensive applications, or switch to 1920 × 1080 at 120Hz for increased smoothness when displaying dynamic content or live streams.

Adapt your display to your pace

Dual Mode boosts your productivity by offering ultra-sharp 4K resolution for precision work and analysis, or a responsive Full HD 120Hz mode for perfect smoothness on live streams and dynamic content. One screen, two smart ways to stay efficient, without compromise.
