Multi-Monitor Calculator

Our multi-monitor calculator helps you determine total desk space requirements, combined resolution, and effective screen area when running multiple displays. Whether you're building a productivity workstation, trading desk, or gaming setup, understanding your multi-monitor dimensions ensures everything fits your workspace.

Running multiple monitors significantly increases your usable screen real estate. Two 27-inch monitors provide 47+ inches of horizontal workspace, while three monitors create an immersive curved setup ideal for simulation gaming, video editing, and financial trading applications.

Dual Monitor Setup

The most common configuration, dual monitors provide 100% more screen space for multitasking. Place your primary monitor directly ahead with the secondary at an angle, or center both monitors with the bezel at your nose for symmetric viewing.

Triple Monitor Setup

Triple monitor configurations excel for sim racing, flight simulation, and panoramic productivity. The center monitor serves as your primary focus while flanking displays provide peripheral content or additional workspace.

Vertical Stacking

For limited desk width, consider stacking monitors vertically. A horizontal primary with a vertically-mounted secondary above provides excellent screen real estate for coding, document comparison, and reference material while fitting narrower desks.

Running multiple monitors requires adequate GPU video outputs. Most modern graphics cards support 3-4 simultaneous displays through various combinations of DisplayPort, HDMI, and USB-C connections. Ensure your graphics card has sufficient ports before purchasing monitors.

For gaming across multiple displays, GPU performance requirements scale with total pixel count. Driving three 1440p monitors at high refresh rates demands significantly more graphics power than a single display. Consider resolution and frame rate requirements when planning your setup.
