High Content Detail
The Iiyama G-Master GB2771HSU-B1 monitor is based on an IPS panel with advanced features, and it delivers both static and dynamic content well. This makes the model applicable as a versatile solution for gaming, multimedia, home, and office use.
The 27-inch display operates at a refresh rate of 240 Hz, featuring low input lag and a fast response time of 0.4 ms. This helps achieve a smooth picture without noticeable freezing and artifacts in dynamic scenes. Additional technologies include Flicker-Free to reduce flickering, as well as NVIDIA G-Sync and Adaptive-Sync for video synchronization.
HDR support contributes to a richer and clearer image with better detail handling. For gamers, the Black Tuner function is useful as it brightens dark areas of the scene, helping to detect objects in shadow more quickly. At the same time, the model's cost is usually lower than that of more renowned brands.
Additional Features
The manufacturer equipped the monitor with a modern set of features. In addition to standard interfaces, the model includes a USB hub for convenient connection of storage devices and peripherals via USB-A and USB-C.
Built-in speakers with a total power of 4 W are located on the sides of the casing. They're sufficient for basic multimedia tasks, video calls, and daily content viewing without the need for external speakers.
The functional stand deserves special attention. It can be adjusted to fit the workspace and, if necessary, the screen can be rotated vertically into portrait mode. This is convenient for viewing matching videos, social media and chat interactions, document work, or creative tasks.
