1440pQuad

1440pQuad is a term used in display technology to describe a configuration that combines four 1440p image streams into a single, large desktop. In practice, it often denotes a 2-by-2 tiling of 2560×1440 panels, producing an overall effective resolution of 5120×2880. The concept is commonly applied to multi-monitor setups and tiled displays used for immersive or professional workloads. It is not a formal standard but a descriptive label used by vendors and users.

Implementation typically requires hardware and software capable of driving multiple outputs and mapping them to one logical display. This can involve a DisplayPort MST hub, a high-end graphics card with several outputs, or a multi-GPU setup. Bezel compensation or bezel correction features are commonly used to minimize the visual gap between panels. Achieving consistent color, brightness, and gamma across all panels may require careful calibration and matching of panel characteristics.

Performance and practicality depend on the GPU, the applications, and the desired refresh rate. Driving four panels at 1440p per panel increases bandwidth and processing demands compared to a single 1440p display, and may reduce achievable frame rates in graphically intensive tasks. Power consumption, cooling, and driver support are additional considerations.

Applications for 1440pQuad include professional workflows such as video editing, photography, and computer-aided design, as well as gaming and simulation environments that benefit from a large desktop area. Variants and terminology vary by vendor, and users should verify compatibility with their hardware and driver ecosystem.
