In today’s fast-paced digital world, having a single monitor can be a significant limitation, especially for professionals who require multiple screens to multitask efficiently. While traditional methods of connecting multiple monitors often involve complicated setups and expensive hardware, a simpler solution has emerged: using USB to connect two monitors. But can you really connect 2 monitors with USB? In this article, we’ll delve into the world of USB monitor connectivity, exploring the possibilities, limitations, and benefits of this innovative technology.
Understanding USB Monitor Connectivity
USB monitor connectivity is made possible by a technology called USB Alternate Mode (Alt Mode). This feature allows USB-C ports to carry non-USB signals, such as DisplayPort, HDMI, or VGA, enabling the connection of monitors to a computer via a USB-C cable. This technology has revolutionized the way we connect our devices, making it possible to power, data transfer, and display video all through a single cable.
Types of USB Monitor Connectivity
There are two primary types of USB monitor connectivity:
- USB-C with DisplayPort Alternate Mode (DP Alt Mode): This type of connectivity uses the DisplayPort protocol to transmit video signals over a USB-C cable. It supports resolutions up to 4K at 60Hz and is commonly used in modern laptops and desktops.
- USB-C with MHL (Mobile High-Definition Link): This type of connectivity uses the MHL protocol to transmit video signals over a USB-C cable. It supports resolutions up to 4K at 30Hz and is commonly used in mobile devices and some laptops.
Benefits of USB Monitor Connectivity
Connecting two monitors with USB offers several benefits, including:
- Simplified Setup: USB monitor connectivity eliminates the need for complicated setups and expensive hardware, making it easy to connect multiple monitors to your computer.
- Increased Productivity: With two monitors, you can multitask more efficiently, increasing your productivity and reducing the need to constantly switch between applications.
- Space-Saving: USB-C cables are thinner and more compact than traditional video cables, making them ideal for cluttered workspaces.
- Cost-Effective: USB monitor connectivity can be more cost-effective than traditional methods, as it eliminates the need for separate video cables and adapters.
Hardware Requirements
To connect two monitors with USB, you’ll need the following hardware:
- A computer with a USB-C port that supports DisplayPort Alternate Mode (DP Alt Mode) or MHL

Method 2: Using a USB-C Cable with DisplayPort Alternate Mode (DP Alt Mode)
- Connect the first monitor to your computer’s USB-C port using a USB-C cable with DP Alt Mode.
- Connect the second monitor to the first monitor using a USB-C cable with DP Alt Mode.
- Configure your computer’s display settings to recognize the two monitors.
Limitations of USB Monitor Connectivity
While USB monitor connectivity offers several benefits, it also has some limitations:
- Resolution and Refresh Rate: USB monitor connectivity may not support the same resolutions and refresh rates as traditional video cables.
- Compatibility: Not all computers and monitors support USB monitor connectivity, so it’s essential to check compatibility before purchasing hardware.
- Power Delivery: USB-C cables may not be able to deliver enough power to larger monitors, so it’s essential to check the power requirements of your monitors before connecting them.
Troubleshooting Common Issues
If you encounter issues when connecting two monitors with USB, try the following troubleshooting steps:
- Check that your computer and monitors support USB monitor connectivity.
- Ensure that your USB-C cable is compatible with your computer and monitors.
- Restart your computer and monitors to ensure that they are recognized by the operating system.
- Adjust your computer’s display settings to optimize the performance of your monitors.
Conclusion
Connecting two monitors with USB is a convenient and cost-effective way to increase your productivity and multitasking capabilities. While there are some limitations to this technology, the benefits far outweigh the drawbacks. By understanding the types of USB monitor connectivity, hardware requirements, and connection methods, you can easily set up a dual-monitor workstation that meets your needs. Whether you’re a professional or a gamer, USB monitor connectivity is an innovative solution that can help you achieve your goals.
