Immersive 34-inch UWQHD curve

This 34-inch ultrawide monitor uses a Rapid VA panel with a 1000R curvature, a 3440 x 1440 resolution and a 21:9 aspect ratio. A 200 Hz refresh rate and 0.5 ms GTG response time target competitive gamers who want fluid motion and minimal ghosting. The 3500:1 contrast ratio and 300 cd/m² brightness add depth to darker scenes. HDR Ready support and 16.7 million colours round out the visual package.

GPU and desk readiness

Your graphics card must deliver a 3440 x 1440 signal at up to 200 Hz over a compatible video output; check the port versions on your GPU before ordering. The 1000R curve demands a viewing distance close to one metre for the intended wrap-around effect, so confirm desk depth allows that spacing. The stand provides height, swivel, pivot and tilt adjustments; verify the footprint suits your available surface area. Adaptive Sync works with supported GPUs to eliminate tearing without extra configuration.

Thermals and daily operation

The monitor draws power only for the panel and backlight; no active cooling fans are present, so operation is silent. Typical heat output is low and dissipates passively through the matte black cabinet. The Less Blue Light mode, certified by TÜV Rheinland (Q 50663685, 2025-03-11), reduces short-wavelength emission for longer sessions. With 178° horizontal and vertical viewing angles, colour and brightness remain stable from off-centre positions.

Questions about this item

Will the 34-inch 21:9 panel fit on a standard dual-monitor arm?

The monitor uses a 1000mm radius curve and weighs within typical VESA limits; the included stand offers height, swivel, pivot and tilt adjustment, and the 100 x 100 mm VESA pattern works with most arms.

Can my GPU drive 200 Hz at 3440 x 1440 over a single cable?

The panel supports 200 Hz at the native 3440 x 1440 resolution via Adaptive Sync; any modern GPU with DisplayPort 1.4 or HDMI 2.0 bandwidth can deliver that rate.

Is the HDR performance strong enough for late-night gaming in a dark room?

The display is HDR Ready with 300 cd/m² peak brightness and a 3500:1 contrast ratio, so dark scenes show deeper blacks than typical IPS panels, though it does not meet high-certification HDR tiers.
