Immerse yourself in ultrawide gaming and productivity with a 34-inch curved display, detailed UWQHD resolution, smooth 120Hz refresh rate and AMD FreeSync Premium.
Experience Immersive Ultrawide Gaming
The Acer Nitro ED343CUR J0 is a 34-inch curved gaming monitor designed for immersive entertainment, responsive gameplay and multitasking. Its UWQHD resolution of 3440 × 1440 delivers detailed visuals across a 21:9 ultrawide screen, giving you more horizontal workspace than a conventional 16:9 display.
The 1000R curvature wraps the screen around your field of view, while the 120Hz refresh rate and 1ms VRB response-time specification support smooth, responsive on-screen action. AMD FreeSync Premium helps synchronise the display's refresh rate with compatible graphics hardware to reduce visual tearing and stuttering.
