The representative of the G-Master gaming line from the Iiyama brand is a mid-budget 27-inch monitor, and considering its support for 3840x2160 resolution, it can be regarded as a relatively affordable option. A standout feature of this model is Dual Mode (also known as Dual Refresh Rate), which allows for a maximum refresh rate of 144 Hz at full detail, while in Full HD format, it doubles to 288 Hz.
Additionally, tailored for gamers, it boasts a fast response time of 0.8 ms and supports current adaptive sync technologies such as AMD FreeSync Premium, Adaptive-Sync, and NVIDIA G-Sync Compatible. To emphasize its gaming orientation, it includes the Black Tuner feature for brightening dark frame zones. The Iiyama G-Master GB2771UHSU-B1 is equipped with an IPS panel supporting 10-bit color depth — 8-bit panel + FRC.
The image is characterized by wide viewing angles, a good brightness level up to 450 nits, and a slightly increased static contrast ratio of 1500:1. Furthermore, the model's advantages include excellent equipment, featuring built-in speakers (two at 2 W), an ergonomic stand with the option to switch the screen to portrait mode, and a rich array of interfaces. Alongside two HDMI 2.1 and DisplayPort v.1.4, there is a hub with four USB ports — two standard and two Type C for connecting various peripherals or charging mobile devices.
