23.8-inch IPS1920×1080 / 120HzHDMI + DisplayPortTilt stand / VESA100
The iiyama ProLite X2491H-B1 is a 23.8-inch IPS desktop monitor with Full HD resolution and a refresh rate up to 120Hz. A matte panel, four-side slim bezel design and 1500:1 native contrast suit everyday office work and multimedia. HDMI and DisplayPort inputs connect to a compatible computer, while a headphone output provides private audio.
Best For: Office documents, browsing, study and multi-monitor desktop arrangements where a compact Full HD display and smooth motion are useful.
Before you order: This X2491H-B1 has a tilt-only stand and no built-in speakers. Check the exact model rather than assuming the height adjustment of XB variants or the audio features of HS variants. For 120Hz, use a supported output, suitable cable and the correct operating-system refresh setting. Additional screens and desktop arms are separate.
