by KePu 24 Jul 2025

Setting up dual monitors can significantly enhance your productivity, improve multitasking, and provide a more immersive experience for both work and entertainment. Whether you're a gamer, content creator, or someone who simply needs more screen space, extending your desktop with a second monitor is a game-changer. This guide will walk you through the steps to set up dual monitors on Windows and macOS and help you troubleshoot common issues.

Part 1: Understanding Dual Monitor Setups

What Is a Dual Monitor Setup?

A dual monitor setup involves connecting two separate screens to your computer. This allows you to use two different displays at once, either to extend your workspace or duplicate content.

Part 2: Requirements for Multi-Monitor Setups

Types of Monitors

  • Standard Monitors: These are the typical screens you might use for everyday tasks, including FHD (1080p) monitors.

  • Portable Monitors: For users on the go, portable monitors like Cevaton P5 or Cevaton S6 are ideal. These devices offer plug-and-play solutions to extend your laptop’s display with minimal setup.

Graphics Card Compatibility

For dual monitor setups, you’ll need a graphics card that supports multiple outputs. Most modern GPUs support dual displays, but it's important to ensure that your computer's GPU and ports are compatible with the monitors you wish to use.

Required Cables and Adapters

  • HDMI, DisplayPort, and USB-C are the most common types of connections for dual monitors. Some monitors may also require specific adapters.

  • Cevaton S6 and Cevaton P5 monitors support USB-C, making them easy to connect to laptops with limited ports, saving space and providing seamless integration.

Desk and Mounting Options

Dual monitors require ample desk space. Additionally, using a monitor arm or stand can help manage the monitors' positions and save desk space, providing more flexibility in arrangement.

Step 3: Configure Display Settings in Windows

  1. Right-click on your desktop and select Display settings.

  2. Scroll to the “Multiple Displays” section and select Extend these displays or Duplicate these displays.

  3. Drag the monitor icons to match their physical arrangement on your desk.

  4. Click Apply and then Keep changes.

Step 4: Set Up in macOS

  1. Open System Preferences > Displays.

  2. Click Arrangement and uncheck Mirror Displays.

  3. Adjust the monitor arrangement as needed.
