How to Set Up an Extended Desktop with Only One VGA Output: Expert Guide

Setting up an extended desktop with only one VGA output from your computer can be accomplished using a variety of methods, each with its own advantages and limitations. Below, we explore the best options for achieving a true extended desktop setup.

Introduction

For users seeking to expand their workspace, the challenge can arise when only one VGA output is available from your computer. This article outlines the most effective methods to achieve an extended desktop on such setups, ensuring a seamless and efficient work experience. From VGA splitters to USB to VGA adapters, and even the use of a docking station, we'll guide you through the process step by step.

1. Using a VGA Splitter

A VGA splitter takes a single VGA output and splits it into two, allowing you to connect two monitors. However, it's important to note that most VGA splitters will mirror the display rather than extend it. For a true extended desktop setup, a VGA splitter is not the right choice, as it will present the same content on both monitors instead of extending the desktop.

2. Using a USB to VGA Adapter

Step 1: Purchase a USB to VGA Adapter

Choose a USB to VGA adapter that is compatible with your operating system. Ensure that it meets the requirements of both your computer and the monitors you wish to connect.

Step 2: Install Drivers

Follow the manufacturer's instructions to install the necessary drivers for the adapter. This ensures that the adapter works seamlessly with your computer's operating system.

Step 3: Connect the Adapter

Plug the USB to VGA adapter into a USB port on your computer. Then, connect your second monitor to the adapter using a VGA cable.

Step 4: Configure Display Settings

- On Windows: Right-click on the desktop, select 'Display settings', and under 'Multiple displays', choose 'Extend these displays'
- On macOS: Go to 'System Preferences -> Displays' and select the option to extend the display.

3. Using a Docking Station

Step 1: Connect the Docking Station

If you are using a laptop or a compatible desktop, a docking station can provide multiple video outputs, including VGA. Connect the docking station to your computer via USB-C or Thunderbolt, depending on the model.

Step 2: Connect Monitors

Connect your monitors to the docking station using a VGA cable and any other available ports.

Step 3: Configure Display Settings

Follow the same steps as mentioned in the USB to VGA adapter section to set up extended displays.

4. Using a Second Computer with Software Solutions

If you have access to a second computer, you can use software solutions such as Synergy or Mouse Without Borders to control both computers with a single mouse and keyboard, effectively extending your workspace across two machines.

Conclusion

The best options for achieving a true extended desktop setup with only one VGA output are the USB to VGA adapter or a docking station. Ensure compatibility and follow the installation instructions for the optimal results. These solutions offer seamless integration and an enhanced work environment, making them ideal for users looking to maximize their digital workspace.
