iiyama Prolite XUB2491H-B1 24"

Manufacturer: iiyama

The iiyama Prolite XUB2491H-B1 is a 23.8-inch standard desktop monitor built around an IPS panel with LED backlighting. It carries a 100Hz refresh rate alongside a quoted 0.5ms response time, making it a straightforward choice for everyday computing and general office use. The matte, anti-glare surface helps reduce reflections in well-lit environments, and the stand supports both tilt and swivel adjustments as well as VESA mounting for those who prefer an aftermarket arm.

Colour reproduction is handled by an IPS panel covering 96% of the sRGB colour space with a typical brightness of 300 nits and a contrast ratio of 1300:1, while the display renders up to 16.7 million colours at a pixel density of 92 ppi. Connectivity consists of one HDMI port, one DisplayPort output, and a 3.5mm audio jack, though there are no USB ports, USB-C, or adaptive synchronisation support. Operating power draw is rated at 16W, and the unit weighs 5,100g with overall dimensions of 539.5mm wide by 343mm tall and 209.5mm deep.

Pros
  • The IPS panel offers wide 178-degree viewing angles both horizontally and vertically, ensuring consistent colour and clarity across a broad range of positions
  • The stand supports both tilt and swivel adjustments, and the monitor is VESA mount compatible, giving useful flexibility in how it can be positioned
  • A 100Hz refresh rate paired with a 0.5ms response time provides noticeably smoother motion handling compared to standard 60Hz displays
  • The matte panel with anti-glare coating helps maintain a clear image in environments with ambient or direct lighting
  • At 16W operating power consumption, the monitor runs efficiently during everyday use
Cons
  • There are no USB ports of any kind, limiting the monitor's usefulness as a connectivity hub at the desk
  • Adaptive synchronisation is not supported, which may result in screen tearing during fast-moving content
  • The monitor does not support portrait mode rotation, reducing flexibility for certain workflows
  • No built-in speakers are included, requiring a separate audio solution for sound output
  • The EU energy label rating of E indicates relatively lower energy efficiency within current standards
  • Picture-in-Picture is not available, restricting multitasking display options
Who is this for?

This monitor suits users who need a reliable everyday display for office work, document editing, and general computing, where the IPS panel with 96% sRGB coverage ensures accurate and consistent colours across the screen. The 100Hz refresh rate and 0.5ms response time also make it a reasonable fit for casual gaming or light multimedia use where smoother motion is preferable over a standard 60Hz panel. Those who value ergonomic flexibility will appreciate the tilt and swivel stand combined with VESA mount support, while the matte anti-glare surface makes it a practical choice for well-lit office or home office environments.

Who is this NOT for?

Users who rely on adaptive synchronisation technologies for a tear-free gaming experience will find this monitor lacking, as no such support is provided. The absence of USB ports and USB-C connectivity makes it a poor fit for those who need a monitor to double as a desk hub for peripherals or laptop charging. The monitor also falls short for professionals who work across multiple sources simultaneously, as Picture-in-Picture is not available, and the lack of portrait mode rotation limits its appeal for coding, reading long documents, or vertical content workflows.
