Description

The iiyama ProLite X4373UHSU-B2 is a 43-inch 4K desktop monitor — the screen area of four 21.5-inch Full HD displays with no bezels breaking it up. That is the case for it: dashboards, trading and control-room layouts where windows need to sit side by side rather than stacked behind each other.

Dual Mode switches between 3840 x 2160 at 60Hz for detail work and 1920 x 1080 at 120Hz for live feeds and moving content. The VA panel gives 4000:1 static contrast, 450 cd/m2 brightness, 178-degree viewing angles and 1.07 billion colours covering 100% of sRGB, with a 3ms grey-to-grey response and HDR10 support.

USB-C carries DisplayPort Alt Mode with 95W power delivery, so a laptop charges and displays over one cable, and a built-in KVM switch plus a four-port USB hub let one keyboard and mouse drive two machines. Two 7W speakers, a headphone hook, flicker-free operation, a blue light reducer and a supplied remote control round it out. VESA 200 x 100 mm, 41W typical draw.

Key features

Four Full HD screens' worth of space

43 inches of 4K with no bezels through the middle — the reason to choose it over a multi-monitor array.

Dual Mode 4K/60 or FHD/120

Switches between resolution for detail work and refresh rate for live feeds without changing hardware.

USB-C with 95W power delivery

One cable for picture, data and laptop charging, with a KVM switch and four-port USB hub behind it.

VA panel at 4000:1

Deeper blacks than an IPS of the same class, which matters on dark dashboards and long viewing sessions.

Full delivery & returns policy

Bought in the UK, backed in the UK

  • This item is sourced through UK distribution and ships to you from within the UK, so the order never crosses a customs border.

  • The manufacturer warranty is honoured here in the UK. If something fails, you deal with us, not with an overseas seller in another time zone.

  • Our own UK-based engineers install, commission and support what we sell, and can attend site when a system needs hands on it.

  • Delivered within the UK mainland, so there is no import duty, customs charge or courier handling fee waiting for you on delivery.

  • Prices are in pounds sterling with proper UK VAT invoices, and purchase orders are accepted from approved education accounts: no currency conversion and no surprises at the door.
