iiyama Prolite XU2491H-B1 24"

Manufacturer: iiyama

The iiyama Prolite XU2491H-B1 is a 23.8-inch standard desktop monitor built around an IPS panel with LED backlighting. Rated at 300 nits of typical brightness, it covers 96% of the sRGB colour space and renders up to 16.7 million colours, making it a straightforward choice for everyday office and general-purpose use. The matte, anti-glare surface helps reduce reflections in typical indoor environments.

Running at a 100Hz refresh rate with a quoted 0.5ms response time, the display delivers reasonably fluid motion handling for its class. Connectivity is kept practical, with one HDMI port, one DisplayPort output, and a 3.5mm audio jack, though there are no USB ports or USB-C. The panel supports wide 178-degree viewing angles both horizontally and vertically, and the stand offers tilt adjustment along with VESA mount compatibility. At 16W operating power consumption, it carries an EU energy label of E.

Pros
  • The IPS panel delivers wide 178-degree viewing angles both horizontally and vertically, ensuring consistent image quality across a broad range of positions
  • A 100Hz refresh rate combined with a 0.5ms response time provides noticeably smoother motion handling compared to standard 60Hz office displays
  • The matte, anti-glare coating reduces reflections under typical indoor lighting conditions, making extended screen use more comfortable
  • 96% sRGB coverage and a 1300:1 contrast ratio offer solid colour reproduction for general productivity and content consumption
  • VESA mount support gives flexible installation options beyond using the included stand
  • Standby power consumption of just 0.5W keeps idle energy draw to a minimum
Cons
  • No adaptive synchronization support, which may result in occasional screen tearing during fast-moving content
  • The stand lacks swivel movement and does not support portrait mode rotation, limiting ergonomic flexibility
  • There are no USB ports of any kind, reducing the monitor's usefulness as a desktop hub
  • No built-in speakers and no support for any surround sound formats means external audio hardware is always required
  • The EU energy label of E indicates relatively low energy efficiency for its class
  • Picture-in-Picture is not available, restricting multitasking directly on the display
Who is this for?

This monitor is well suited to office workers and general home users who spend long hours in front of a screen, thanks to its matte anti-glare IPS panel with wide 178-degree viewing angles that keep the image consistent and comfortable across extended sessions. The 100Hz refresh rate and 0.5ms response time also make it a reasonable choice for casual gamers or users who want smoother everyday interactions without stepping into dedicated gaming monitor territory. Its VESA mount compatibility adds practical value for those looking to set up a cleaner, space-efficient workstation.

Who is this NOT for?

Users who need flexible desk ergonomics will find this monitor limiting, as it lacks swivel and portrait mode support. It is also a poor fit for those who rely on a monitor to act as a desktop connectivity hub, given the complete absence of USB ports and USB-C. Creative professionals or colour-critical workflows requiring hardware colour calibration will find the lack of that feature restrictive, and competitive gamers who depend on adaptive synchronization to eliminate screen tearing will need to look elsewhere.
