Description

The iiyama G-MASTER GB2771UHSU-B1 is a 27" (68.6 cm) 4K UHD IPS LED monitor offering 3840×2160 resolution and a native 16:9 aspect ratio.

How to use

Connect the monitor to your PC or console using the appropriate video cable and configure the display resolution and refresh rate in your system settings to match your use case (4K/144Hz for high‑detail work or immersive play, Full HD/288Hz for maximum responsiveness).
