The iiyama G‑MASTER GB2790QSU‑B5 is a high-performance gaming monitor designed for competitive gamers who need ultra-smooth motion and low latency. It uses a Fast-IPS panel which delivers wide viewing angles and accurate colour reproduction across the screen.

With its 2560 × 1440 (WQHD) resolution, the monitor offers detailed visuals and more on-screen space compared to Full HD without pushing your GPU as hard as 4K. The 240 Hz refresh rate and 1 ms MPRT response time combine to provide extremely fluid visuals and minimal motion blur — ideal for fast-paced esports and action games.

The monitor supports FreeSync Premium, helping to eliminate screen tearing and stuttering by synchronising frame rates with compatible GPUs. The Black Tuner feature lets you brighten dark areas, helping you spot enemies or details in shadowed scenes.

Connectivity is robust: there’s DisplayPort 1.4 for high refresh-rate output, HDMI 2.0, and a 2-port USB 3.2 Gen 1 hub for peripherals. A headphone socket provides private audio, and the monitor also includes built-in 2 W speakers.

For ergonomics, the stand supports 150 mm of height adjustment, plus tilt and pivot, making it easy to find a comfortable viewing position. The monitor is also VESA 100 × 100 mm mountable, so it’s easy to fit on a monitor arm or wall.

Eye comfort features include flicker-free technology and a blue-light reduction mode to reduce eye strain during long gaming or working sessions. It also supports HDR400 for enhanced contrast and brightness.

Overall, the GB2790QSU-B5 combines top-tier speed, precision, and build quality in a 27″ form factor, making it a great choice for competitive and immersive gaming.
