The iiyama G-MASTER Red Eagle GCB3484WQSU-B2 is a 34-inch curved gaming monitor built for competitive play and immersive ultrawide experiences. It combines a 200Hz refresh rate with a 1500R curved VA panel to reduce latency and wrap your field of view, while a Dual Mode option pushes to 400Hz at lower resolution for esports titles where every millisecond counts.
Why This Product
-
Ultrawide 3440×1440 VA panel
— The 21:9 aspect ratio and curved design expand your peripheral vision without needing multiple screens. VA technology delivers a 4000:1 contrast ratio for deeper blacks and richer colours.
-
200Hz native, 400Hz in Dual Mode
— Switch between smooth 200Hz at full ultrawide resolution or jump to hyper-fast 400Hz at lower resolution via DisplayPort for competitive shooters and fighting games.
-
0.6ms response time
— MPRT response time keeps ghosting minimal during fast camera pans and combat. Combined with 200Hz, motion feels fluid across the entire curved display.
-
DisplayHDR 400 and Target Assist
— HDR brings brighter highlights and sharper contrast to every scene. The built-in Target Assist crosshair function operates at the hardware level, unaffected by in-game settings.
-
AMD FreeSync Premium sync
— Eliminates tearing and stuttering on compatible AMD and many NVIDIA cards by locking frame delivery to monitor refresh.
-
Height-adjustable stand with USB hub
— Ergonomic design tilts and adjusts to your eye level. Built-in USB 3.2 Gen 1 hub puts three extra ports within arm's reach.
