Key Features
UWQHD ultra-wide display format
The 3440 × 1440 resolution works alongside a 21:9 aspect ratio to create a panoramic visual environment. This format is ideal for expansive game worlds, detailed creative projects, and workspace arrangements that benefit from a wider display layout.
1500R curved screen design
The display features a 1500R curvature that helps maintain visual consistency from edge to edge. By creating a more uniform viewing distance across the panel, the curved structure contributes to a more engaging and natural on-screen experience.
120Hz refresh rate
A refresh rate of up to 120Hz enables smoother frame transitions and improved visual responsiveness. Fast-moving action appears more refined, helping maintain clarity during gaming and other dynamic content.
1ms VRB response performance
The monitor supports Visual Response Boost technology, delivering response times as low as 1ms. This helps preserve image sharpness during rapid motion sequences and reduces visible blurring in fast-paced scenes.
AMD FreeSync Premium support
The display is engineered to operate efficiently with compatible AMD graphics solutions, helping maintain smoother frame delivery throughout gameplay sessions. This results in more consistent visual performance during demanding gaming scenarios.
HDR10 visual enhancement
HDR10 capability expands the monitor's ability to represent variations in brightness and contrast. This allows highlights, shadows, and fine image details to appear with greater depth and visual impact.
Modern connectivity configuration
Equipped with HDMI 2.1 and DisplayPort 1.4 interfaces, the monitor supports high-resolution output and modern gaming hardware. These connectivity options provide flexibility when connecting PCs, gaming consoles, and multimedia devices.
