Fortunately, this can be done using various external devices and adapters. This guide will show you different methods to connect two monitors to one computer with one HDMI cable. Read on to learn more.

 

What are the Advantages of HDMI Ports?

Most computers, laptops, and consoles will have one or more HDMI ports. Unlike old VGA ports, a High Definition Multimedia Interface port or HDMI provides more modern features, like the ability to provide both audio and video in one connection.

Besides that, here are some advantages of HDMI ports on computers:

  • Modern HDMI connections support a 120 Hz refresh rate; this is essential in providing superb images and video when displaying content on another output device. It can also handle more data, which is excellent for gaming and streaming.
  • Modern HDMI 2.1 cables can host approximately 48 Gbps of data and are suitable for high-bandwidth tasks.
  • Nowadays, most home entertainment systems are HDMI-compatible since it helps in cable management and is less susceptible to interference.

 

How to Connect Two Monitors to One Computer With One HDMI Port

Whether for gaming, work, or entertainment, you’ll likely want an additional monitor added to your current computer setup. To run two monitors on your computer using only one HDMI port, you can either use an HDMI splitter, an adapter, or a docking station.

For the steps on using these devices, refer to the methods below. Remember to review each method and check which one works out for your dual-monitor setup:

 

Method #1: Connect Two Monitors on One HDMI Port Using an HDMI Splitter

One of the quickest ways to connect two monitors on your computer with one HDMI port is by using an HDMI splitter. This way, you can connect two monitors to your computer using only one HDMI port. However, this method requires two HDMI cords since they need to be connected separately on the splitter.

To have a dual-monitor setup on your computer using an HDMI splitter, follow these steps:

  1. Find the HDMI port on your computer. 
  2. Once found, plug in the end of the HDMI splitter on this port.
  3. Next, connect two separate HDMI cables to your monitors. Plug the other end of these cables into the splitter.
  4. Turn on your computer along with the two monitors. You will now have an extended view of your desktop on both screens.

Ideally, if you’re looking forward to playing high-resolution games, streaming, or working on detailed graphics and editing, you should pick an HDMI splitter that supports 4K and at least a 60 Hz refresh rate.

 

Method #2: Connect Two Monitors With One HDMI Port Using an Adapter

Another way to connect two monitors with one HDMI port is by using adapters. For instance, you’ll need to use a VGA to HDMI adapter if you’re using a computer that supports VGA outputs and wants to connect your second monitor with an HDMI input. This method is also cost-effective since a wide variety of adapters are available at a low price.

To connect two monitors with one HDMI using an adapter, proceed to these steps:

  1. Connect your first monitor to your computer’s HDMI-OUT port.
  2. Next, check your computer’s other ports for display output. Also, check your monitor’s supported input and get the appropriate adapter. (e.g., get a VGA to HDMI adapter once your computer supports VGA outputs and your monitor supports HDMI.)
  3. Connect the adapter to your computer’s VGA output and the other end to your second computer.
  4. Then, plug in one end of the HDMI cable to your monitor and the other to the adapter. Your computer display will now be extended to the two monitors.

These steps also apply to various adapters, such as DisplayPort to HDMI, USB to HDMI, and other Type-C video adapters.

 

Method #3: Connect Two Monitors With One HDMI Port via a Docking Station

If you want a dual-monitor setup using a powerful device, you can use a docking station. Besides connecting additional HDMI monitors, you can also use it to connect other devices that support Type-C, DVI, and VGA. To use a docking station, you’ll just need to use a suitable video cable for your monitor. 

However, since docking stations will need additional power to link the connected devices to your computer, you’ll need to plug it into a power source. Once the second monitor is connected, turn your monitors on and your computer on—you will now have an extended desktop display.

 

Final Thoughts

If you’re deciding on connecting an additional second monitor for your current computer setup, there are various methods that you can follow. However, if your computer has more than one display port—which is the case for most computers that support dual monitors—it’s best to use an adapter (Method 2).

Hopefully, this guide helps you on connecting two monitors to your computer with one HDMI port.
