Key Features
34-inch | 21:9 UltraWide Display | 3440×1440 Resolution | PBP Support
The “34U640B-BAJP” offers a 33% wider screen than typical 16:9 monitors and a high resolution of 3440×1440, designed to enhance work efficiency. This allows users to display two software applications side-by-side or view large spreadsheets in full screen, catering to the needs of business professionals and content creators who handle vast amounts of information daily. Furthermore, with Picture-by-Picture (PBP) support, multiple PCs can be connected, splitting the screen into two 1720×1440 displays for efficient multitasking. The 21:9 aspect ratio is also nearly identical to cinematic widescreen, providing an immersive movie-watching experience.
1800R Curved Display | sRGB 99% (Typical) | HDR10 | Factory Calibration
The 1800R curved display enhances immersion by providing a viewing experience closer to natural human vision, minimizing distance differences between the screen center and edges. This reduces the need for constant refocusing. The monitor covers 99% of the sRGB color space, making it suitable for photo and video editing. It also supports HDR10, enabling accurate and detailed color reproduction. Each unit undergoes factory calibration, ensuring consistent and stable color accuracy out of the box.
USB Type-C™ (Up to 65W USB PD)
Equipped with a USB Type-C port, the monitor allows for display connection, power delivery (up to 65W USB PD), and data transfer with a single cable. This simplifies the setup for notebook PCs and helps create a clean and organized home office environment in limited spaces.
144Hz Refresh Rate | DAS Mode
The monitor supports a 144Hz refresh rate (100Hz via HDMI), offering smooth visuals that enhance comfort and productivity. The Dynamic Action Sync (DAS) Mode minimizes input lag, making it beneficial for fast-paced gaming where split-second reactions are crucial.
Blue Light Reduction Mode | Flicker Safe | Ergonomic Design
For user comfort, the monitor includes a “Blue Light Reduction Mode” to minimize blue light emission and “Flicker Safe” to suppress screen flicker. It also features a “Color Weakness Mode” to assist individuals with certain color vision deficiencies in distinguishing colors, though it does not guarantee full color discrimination for all users. The ergonomic stand allows for 80mm height adjustment and tilt from -5° to 15°, providing flexible viewing options.
