Tired of motion blur and lag stealing your victories? The iiyama G-MASTER gives you razor-sharp frames and instant response, so you stay ahead of the competition.
iiyama G-MASTER G2741QSU-B1, 27 Inch 4K Ultra HD, QLED 1 ms Gaming Monitor Black
The G2741QSU-B1 packs a 27-inch QLED IPS panel that delivers true 4K Ultra HD detail across 16.7 million colors. With a 144 Hz refresh rate and a 1 ms MPRT response time, fast-paced shooters and high-speed racers appear smooth and fluid. NVIDIA G-SYNC eliminates tearing, while the Black Tuner function lifts hidden details in dark scenes, giving you a tactical edge without sacrificing brightness.
Beyond raw speed, the monitor offers a 350 cd/m² typical brightness and a 1500:1 contrast ratio, so bright highlights and deep shadows coexist naturally. The matte surface reduces glare, and the 178° viewing angles keep colors consistent whether you’re solo or sharing the screen with teammates. Built-in dual 2 W speakers provide clear audio cues, while a USB-2.0 hub lets you connect peripherals without reaching for the PC. Ergonomic tilt from 4-22° and a sturdy VESA-compatible stand let you fine-tune the viewing position for marathon gaming sessions.
