A docking station is a versatile and effective solution for connecting two monitors to a laptop that only has one HDMI port. Generally, a docking station expands the number of available ports on your laptop and lets you connect multiple devices, including additional monitors.

Most docking stations include one or more HDMI ports, along with various other useful connections. For video transmission, ensure that your laptop has a USB 3.0 port or a newer version. Some high-end docking stations might also require an external power source.

To expand on the use of docking stations for connecting two monitors to a laptop when the laptop has only one HDMI port, it is important to understand the versatility and functionality of these devices. Here is a detailed look at how you can achieve this:

  1. Identify Available Ports on Your Laptop

Before you start, check the types of output ports available on your laptop. Common types include HDMI, DVI, VGA, or USB-C. This will determine the kind of docking station you should use.

  1. Select the Right Docking Station

Choose a docking station that complements the ports on your laptop and has the necessary output ports for your monitors. For instance, if you have USB-C or USB 3.0 ports on your laptop, look for a docking station that can connect through these ports and offers multiple video outputs like HDMI, DVI, or VGA.

  1. Connect the First Monitor

If your laptop has an HDMI port, you can connect the first monitor directly to this port using an HDMI cable. This setup will use the laptop’s native HDMI output.

  1. Connect the Second Monitor 

For the second monitor, connect the docking station to your laptop via the appropriate port (e.g., USB-C or USB 3.0). Then, use an HDMI cable (or another type of cable compatible with your monitor) to connect the second monitor to the docking station. If the docking station has multiple video outputs, you can choose the one that matches your monitor’s input.

  1. Configure Display Settings

Once both monitors are connected, you will need to configure your display settings. On a Windows laptop, you can right-click on the desktop and select “Display settings” to arrange your monitors correctly. You can choose to extend your display across both monitors, mirror the same content on both, or use each monitor independently.

  1. Power Considerations

Some docking stations might require external power, so ensure that your docking station is plugged into a power outlet if needed. This is especially important for docking stations that support high-resolution displays or multiple outputs.

Use HDMI Adapters

HDMI adapters are a practical and efficient way to connect two monitors to a laptop, especially when your laptop only has a single port. These adapters are not just for duplicating your laptop’s screen; they also allow you to extend your display across multiple monitors, which can be incredibly useful for multitasking and improving productivity.

There is a wide variety of HDMI adapters available in the market that cater to different port types. Some of the common ones include DisplayPort to HDMI, VGA to HDMI, USB to HDMI, and Type-C to HDMI adapters. Each of these is designed to convert one type of connection into an HDMI output, compatible with most modern monitors.

Here is how to achieve a dual-monitor setup with HDMI adapters:

  1. Determine Your Laptop’s and Monitors’ Ports

Before purchasing an adapter, identify the types of ports available on your laptop and monitors. Common ports on laptops include HDMI, VGA, DisplayPort, and USB-C. Your monitors might have inputs like HDMI, VGA, or DVI.

  1. Select the Appropriate HDMI Adapters

Based on the available ports, choose the right HDMI adapter. For example, if your laptop has a VGA port and your second monitor has an HDMI input, you will need a VGA to HDMI adapter.

But, if your laptop has a DisplayPort and your monitor supports HDMI, opt for a DisplayPort to HDMI adapter. For laptops with USB-C ports, a USB-C to HDMI adapter would be suitable.

  1. Connect the First Monitor

Usually, you can connect the first monitor directly to your laptop using its HDMI port. This will be your primary display.

  1. Set Up the Second Monitor 

Connect the adapter to the appropriate port on your laptop (e.g., VGA, DisplayPort, USB-C). Now, attach an HDMI cable to the HDMI output of the adapter. Finally, plug the other end of the HDMI cable into the HDMI input of your second monitor.

  1. Configure the Display Settings

Once both monitors are connected, they might automatically extend your desktop across both screens. If not, you can manually configure this. Press the Windows key and ‘P’ to open the projection options. Select “Extend” to extend your desktop across both monitors. You can also mirror the displays if you prefer both screens to show the same content.

  1. Adjust Primary and Secondary Displays

In your computer’s display settings, you can choose which monitor is the primary (main) display. This is where your main desktop icons and taskbar will be.

You can also rearrange the display order to match the physical arrangement of your monitors, ensuring a seamless transition of the mouse cursor and windows from one screen to the other.

  1. Considerations for Resolution and Refresh Rate

Keep in mind that the resolution and refresh rate supported by the adapters might differ from what your laptop or monitors can natively support. Make sure that the adapter you choose supports the resolution and refresh rate you desire for your monitors.

Use HDMI Splitter

An HDMI splitter is another useful device for connecting two monitors to a laptop. This method is ideal for scenarios where you want to mirror your laptop’s display across multiple screens. They come in various forms, such as 1 In/2 Out or with multiple output ports. The price of the splitter will vary depending on its type and capabilities. It is important to choose one that suits your needs.

Read below to find out how you can use an HDMI splitter for this purpose:

  1. Set Up the HDMI Splitter

Start by connecting one end of an HDMI cable to the HDMI output port of your laptop. Plug the other end of this cable into the input port of the HDMI splitter. Next, take another HDMI cable and connect one end to the HDMI input of your first external monitor.

Now, connect the other end to one of the output ports on the HDMI splitter. Repeat the same step for your second monitor, using another HDMI cable to connect it to another output port on the splitter.

  1. Installation and Use

After connecting the splitter and monitors, the setup should work immediately, mirroring your laptop’s screen on both monitors. There is usually no need for additional software or complicated configuration.

  1. Understand the Limitations

When using an HDMI splitter, both external monitors will display the same content that is on your laptop’s screen. This is known as screen mirroring. Unfortunately, an HDMI splitter does not allow you to extend your desktop across multiple monitors; it only duplicates the display.

  1. Additional Requirements

Keep in mind that you will need additional HDMI cables for each monitor you wish to connect. This means if you are connecting two external monitors, you will need three HDMI cables in total (one for the connection from the laptop to the splitter and one for each monitor).

  1. Choose the Right Splitter

It is crucial to invest in a quality HDMI splitter. Cheaper models might not support the full resolution or refresh rate of your monitors and will result in poor display quality or performance issues. Make sure the splitter is compatible with your equipment’s specifications.

Use Ports Other Than HDMI

Laptops often come with various types of video output ports, not just HDMI, that can be used to connect two monitors to a single laptop. These include: 

  1. VGA Port

VGA, known for its distinctive trapezoidal shape with three rows of holes, is one of the oldest video output formats. While it’s less common on modern devices, some older laptops and monitors still have VGA ports. If both your laptop and your monitor have VGA ports, you can use a VGA cable to connect them.

  1. DisplayPort and Mini DisplayPort

DisplayPort is another common video output, with the full-sized version looking somewhat similar to HDMI but with one chamfered edge. Mini DisplayPort, which resembles USB-B ports found in printers, is also used in some laptops. These ports can be used to connect to monitors that have DisplayPort inputs.

  1. Thunderbolt Ports

Thunderbolt ports, particularly in versions 1 and 2, use Mini DisplayPort connectors and support video output. If your laptop has a Thunderbolt port, it can be used to connect to a monitor.

  1. USB-C Port

USB-C is a versatile port design used for various purposes, including video output. However, not all USB-C ports support video transmission. The capability depends on the data transfer standard used with the USB-C design. 

Standards like Thunderbolt 3 and 4, as well as USB 4, always support video output. On the other hand, USB 2.0 doesn’t support video, and while USB 3.0, 3.1, and 3.2 have the necessary bandwidth, they may not always have video output capability.

Identifying Video-Capable USB-C Ports

To determine if a USB-C port supports video output, look for specific symbols near the port. A Thunderbolt symbol (a lightning bolt) indicates a Thunderbolt port, which supports video. A DisplayPort symbol (the letter “D” with a “P” inside it) also signifies video-out capability. 

If the port has an “SS” symbol with a trident, it’s likely a USB-C port without video support. In cases where there’s no symbol, the port’s capabilities might be unclear, and you may need to consult the manufacturer’s specifications.

Connecting Monitors Using These Ports 

Once you have identified a usable port other than HDMI, you can connect your monitor using the appropriate cable or adapter. For example, if you are using a DisplayPort, you will need a DisplayPort cable or an adapter if your monitor only supports HDMI.

Setting Up Dual Monitors

After connecting the monitors using these alternative ports, you will need to configure your display settings. This can typically be done by right-clicking on the desktop and selecting “Display settings” to arrange and configure your monitors as needed.


The dual monitor configuration significantly expands your digital workspace and allows more efficient multitasking and a more immersive gaming experience. With the various methods outlined in this article, from using docking stations and HDMI adapters to exploring alternative ports, you can easily overcome the limitation of a single HDMI port. The result is a more versatile and powerful computing setup that caters to both professional and entertainment needs.
