## Long description

The BenQ RD280UA 28.2" 4K Ultra HD 3840 x 2560 is a flat IPS monitor with a native 3:2 aspect ratio designed for precise image rendering and efficient workspace use. Its high resolution and 5 ms response time deliver detailed visuals and smooth on-screen motion, while 178° wide viewing angles maintain consistent color and brightness across horizontal and vertical planes. The monitor includes built-in speakers, a USB hub with a USB Type-C downstream port, height adjustment and VESA mounting compatibility for flexible installation in office or home setups.
Advantages
The RD280UA combines a high pixel density 4K Ultra HD resolution with an IPS panel to provide accurate colors and stable viewing from different positions. The 3:2 aspect ratio gives more vertical workspace compared with widescreen models, useful for documents, code and design layouts. Integrated connectivity features such as a USB hub and USB Type-C downstream port simplify peripheral connections, and the built-in speakers eliminate the need for separate audio devices in basic setups. Ergonomic height adjustment and VESA support enable adaptable placement and mounting options.
Suitable for
Office productivity: viewing documents, spreadsheets and email with increased vertical space
Graphic and web design tasks requiring color stability and high resolution
Software development and coding with extended vertical workspace
Multimedia playback and light content creation using built-in speakers and high brightness
Dual- or multi-monitor setups where VESA mounting and ergonomic adjustment are needed

How to use
Connect the monitor to your computer using the appropriate video cable or USB Type-C downstream port depending on your device’s outputs. Adjust the height to align the top of the screen with your eye level for ergonomic use. Use the on-screen display (OSD) controls to set brightness, contrast and color presets according to your workflow — sRGB or custom modes for color work, and a standard preset for general office tasks. If needed, connect peripherals to the built-in USB hub for simplified cable management and use the integrated speakers for basic audio playback. For wall or arm mounting, follow the VESA mount instructions in the user manual and secure the monitor to a compatible bracket.
Usage recommendations
For color-sensitive work, allow the monitor to warm up for at least 30 minutes and calibrate using a hardware colorimeter. When using the monitor for extended periods, set a comfortable brightness level (typically below 120 cd/m² in low-light environments) and enable ergonomic breaks to reduce eye strain.
