Description
iiyama G-MASTER GCB3484WQSU-B1 is a 34" curved gaming monitor that combines Ultrawide Quad HD clarity with a fast 180 Hz refresh rate for an immersive experience.
The G-MASTER GCB3484WQSU-B1 features a 34" (86.4 cm) VA LED panel with a 3440 x 1440 (UltraWide QHD) resolution and a native 21:9 aspect ratio, delivering expansive horizontal workspace and cinematic visuals ideal for gaming and multitasking.
With a striking 1500R curvature, 500 cd/m² typical brightness and HDR400 support, this monitor emphasises depth and contrast. Its typical static contrast ratio of 4000:1 and dynamic contrast up to 80,000,000:1 bring darker blacks and brighter highlights for more vivid scenes.
Performance-oriented specifications include a 0.4 ms response time (MPRT), AMD FreeSync Premium and VESA Adaptive-Sync support, plus up to 180 Hz maximum refresh rate, reducing motion blur and screen tearing for fast-paced gaming.
The G-MASTER is also designed for convenience and connectivity with two HDMI 2.0b ports, one DisplayPort 1.4, an integrated USB 3.2 Gen 1 hub (two Type-A and two Type-C downstream ports), built-in 2 x 5 W speakers and headphone out. It supports HDCP and offers comprehensive cable inclusion (AC, USB, HDMI, DisplayPort).
Ergonomics and build quality are highlighted by a VESA 100 x 100 mounting interface, height adjustment up to 15 cm, tilt (5–23°) and swivel capability, Kensington lock slot, cable management and a compact footprint (808 x 290 mm with stand).
Typical use cases include competitive and immersive gaming, content creation with wide timelines, and multitasking for professionals who benefit from extra horizontal workspace. The monitor’s gaming-focused features and rich connectivity make it a strong pick for streamers, sim racers and creative professionals.
