February 2020 – The ProLite X4372UHSU, the latest addition to iiyama’s desktop solutions range, combines the power of four Full HD displays in one. Equipped with a 4K IPS matrix, this device delivers outstanding color reproduction and wide viewing angles, making work even more comfortable.
Wide and comfortable, the ProLite X4372UHSU-B1 is a 43-inch display with a 16:9 aspect ratio. With a high-quality IPS panel at 4K resolution (3840 x 2160), this monitor is capable of displaying four times more information than a Full HD screen. Its wide aspect ratio, Ultra HD resolution and PbP (Picture-by-Picture) function — which allows images from up to four different input signals to be displayed simultaneously — make this monitor truly exceptional. You can enjoy a screen area equivalent to four full HD monitors without any bezel interruptions. It also improves workplace comfort by eliminating the typical downside of multi-monitor setups: tangled cables.
All for one and one for all
The ProLite X4372UHSU-B1 is compatible with a wide range of applications in which simultaneously active workloads are the norm, including data analysis, CAD/CAM, photography and data visualization.
Beyond work, watching movies or playing games on this monitor also becomes a real pleasure. The low response time (4 ms) lets you enjoy dynamic games, while HDR technology support makes images in games and films more vivid and colors more saturated.
Comfort above all
The panel comes with multiple digital signal inputs: 2x HDMI (v. 1.2 / 2.0), 2x DisplayPort (v. 1.2) and 4x USB ports (2x v. 3.0 and 2x v. 2.0). A headphone output and 2 x 9W speakers deliver high-quality audio for multimedia use or for professions that specialize in video and audio processing.
Combining Blue Light Reducer and Flicker Free functions with 450 cd/m² brightness and HDR support, the display delivers accurate colors and crisp images.
The back of the display also features a convenient headphone hook and a remote control that allows audio and OSD menu adjustments.
The display can also be mounted on any wall compatible with the VESA standard.
