## Long description

The IIYAMA ProLite X2791QS-B1 is a 27" (68.6 cm) LED monitor with an IPS panel delivering Quad HD 2560×1440 resolution on a flat matt screen. The display offers wide 178°/178° viewing angles, 350 cd/m² typical brightness, 1000:1 contrast ratio and a 0.233 mm pixel pitch for clear detail.

The slim bezel and VESA compatibility enable clean multi-monitor setups and flexible mounting options.

How to use
Place the monitor on a stable desk surface or attach it to a compatible VESA mount. Connect a video source using a supported cable (DisplayPort/HDMI or other supported input depending on your system) and connect power. Adjust display settings using the on-screen menu to set resolution to 2560×1440 and select the preferred refresh rate. Use the built-in speakers or connect headphones to the audio jack if needed. Enable flicker-free and blue light reduction modes in the settings to improve visual comfort during extended sessions.
Usage recommendations
For best image quality, set the operating system and graphics driver to the native 2560×1440 resolution and ensure the video cable supports the desired refresh rate. Position the monitor so the top of the screen is at or just below eye level, and maintain an arm’s length distance to reduce eye fatigue. Regularly use the monitor’s blue light reduction and flicker-free modes during prolonged work. When deploying multiple units, use the slim-bezel edges and VESA mounts to minimise gaps and create a seamless multi-monitor workspace.
