Product information

Description

The IIYAMA ProLite X4373UHSU-B2 is a 43" (109.2 cm) LED monitor offering 4K Ultra HD resolution (3840×2160) on a VA panel. It delivers a combination of high brightness, wide viewing angles and deep contrast suitable for professional workflows. The monitor supports a dual-mode display: native 3840×2160 for detailed content work and 1920×1080 at 120 Hz for smoother motion when showing dynamic feeds. Built-in USB-C power delivery, an integrated USB 3.2 hub, an integrated KVM switch and speakers simplify multi-device setups and reduce desk clutter.

Advantages

The large 43" VA panel provides deep blacks and a high contrast ratio, improving detail in dark scenes while maintaining wide 178° viewing angles. High 450 cd/m² brightness ensures clear visibility in various lighting conditions. Dual display modes let you choose between 4K clarity for data- and content-intensive tasks or a 120 Hz Full HD mode for smoother motion. Integrated features — USB hub, KVM switch, USB-C with power delivery and speakers — enable easier connection, device control and charging from a single screen.

Suitable for

  • Content creation and video/photo editing
  • Financial dashboards and data analysis
  • Control rooms and monitoring stations
  • Multi-device office setups with switching between computers

How to use

Connect your primary device via USB-C to use single-cable video, data and up to 95 W power delivery. Use the integrated USB hub to attach peripherals and connect a second computer to the extra inputs; the built-in KVM switch allows switching control between systems with one keyboard and mouse. Select the appropriate display mode in the monitor OSD or with the remote control: 4K 3840×2160 for detailed work or 1920×1080 at 120 Hz for smoother live or dynamic content. Adjust brightness, picture settings and blue light filter in the OSD for optimal viewing.

Usage recommendations

For extended use sessions enable the flicker-free mode and reduced blue light setting to minimise eye strain. Use the 4K mode for productivity and content editing, and switch to Full HD 120 Hz when monitoring live feeds or video with fast motion. If wall- or arm-mounting, ensure the VESA mount supports the weight and size of a 43" monitor.
