Reading Time: 6 minutes

Dual monitors can increase your productivity and aid multitasking. Find out how to set them up with an HDMI connection on any system.

You may benefit from dual monitors if you frequently switch between applications while working on your computer. This article will show you how to set up dual monitors with HDMI. You will also learn how to configure dual monitors on various operating systems: Windows, macOS, and Linux.

How to Set Up Dual Monitors With HDMI

You’ll need two monitors and an HDMI cable for each to get started. You can use standard HDMI cables if your computer has two HDMI outputs and both monitors have HDMI inputs. However, if your computer has two different video outputs (e.g., HDMI and DisplayPort or DVI), you may need an adapter cable.

Once you have all the necessary equipment, follow these steps to learn how to connect two monitors to a laptop with one HDMI port:

1. Connect HDMI cables to both monitors and plug the other ends into your computer’s video output or graphics card ports.
2. Plug the power cord into an outlet and turn on both monitors.
3. Finally, adjust your computer’s display settings, so each monitor displays a different screen portion. Below, we describe how to configure dual monitors on Windows, macOS, and Linux systems.

How to Configure Dual Monitors on Windows

To configure dual monitors on Windows to display as required, follow these steps:

1. Open System from the Settings section and choose Display. Your computer should be able to detect any external displays that are connected to it automatically.
2. If the monitors are not yet detected, click on the Detect button, and it should be able to detect your monitors.
3. Once your monitors are detected, you can select which one you want to use as your primary display. To do this, click on the monitor you want to use as your primary display and then check the Make This My Main Display Option. You can also rearrange the order of your displays by clicking and dragging them in the Display settings panel.
4. After selecting your primary display, it’s time to adjust the resolution for both monitors. The resolution is the number of pixels displayed on a screen. A higher resolution means more pixels and a sharper image.
5. To change the resolution, click on the monitor you want to adjust and select a new Display Resolution from the drop-down menu, as shown below.
6. If you’re unsure what resolution to choose, it’s generally best to start with the native resolution for each monitor. The native resolution is the highest resolution that a monitor can support without scaling. For example, a 19-inch monitor with a native resolution of 1280×1024 can display images at resolutions up to 1280×1024 without scaling.
7. Once you’ve selected the resolution for a monitor, a prompt to either Keep changes or Revert appears, as shown below:

Once you opt to keep the changes, the resolution will be changed. With the preferred resolution selected for each monitor, your dual monitor setup is now complete.

How to Configure Dual Monitors on macOS

Once both monitors are connected to your Mac, follow these steps to configure them:

1. Open up System Preferences and click on Displays.
2. In the Displays panel, you should see both of your monitors listed. If not, ensure both monitors are powered on and their cables are appropriately connected.
3. Click on the Arrangement tab. You can drag and drop the display to match the monitor arrangement on your desk.
4. Finally, click the Mirror Desktops checkbox to enable mirroring. Mirroring will duplicate your desktop across both screens. Also, the menu bar and dock will default appear on your primary display, but you can drag them to the secondary display if you prefer. You can also choose to have your desktop extend across both displays or have it appear only on one display.
5. To change your display resolution, click the Scaled option in the Displays panel. You can select a preconfigured resolution or create a custom one.

How To Configure Dual Monitors on Linux

Configuring dual monitors on Linux is easy. Once your second monitor is plugged in, follow these steps:

1. Go to your control panel and find the Display settings. If the second monitor isn’t detected, click the Detect Displays button.
2. Once both of your monitors are detected, you’ll need to choose which one will be your primary display. The primary display will show the desktop and launch applications when you start your computer. You can usually set this in the Display settings as well.
3. Finally, you’ll need to adjust the screen resolution and ensure each monitor shows the correct image. You can drag one monitor’s image over the other to arrange them in most cases.

How to Run Dual Monitors With One HDMI Port

You can run dual monitors with one HDMI port by using an adapter or an HDMI splitter. Let’s have a look at each of these methods.

How to Use an HDMI Splitter for Dual Monitors

To set up dual monitors with an HDMI splitter, follow these steps:

1. Identify the HDMI port on your computer.
2. Once you’ve found it, plug the end of the HDMI splitter into this port. Then, plug the two HDMI cables into the splitter.
3. Next, connect one end of each cable to a monitor. However, if your monitors have different inputs (e.g., one has DisplayPort while the other has HDMI), you must use the correct cable/adapter for each monitor.
4. Finally, turn on your monitors and computer; you should see your desktop extended across both screens!

One thing to keep in mind is that not all HDMI splitters are created equal. Some splitters only support specific resolutions, so choosing one that will work with your particular setup is essential. Another consideration is whether you need an active or passive splitter. Active splitters are typically more expensive but offer better performance, especially at longer distances. A passive splitter should suffice if you’re connecting two monitors nearby.

How to Set Up Dual Monitors Using an Adapter

Various adapters are available for dual monitor setup, so selecting one compatible with your computer and monitor is crucial. Once you have the adapter, connect it to your HDMI port and monitor. If not, you may need to change your computer’s display manager settings.

VGA to HDMI Dual Monitor Using an Adapter

If you have a computer with a VGA output and want to connect it to an HDTV or monitor with an HDMI input, you’ll need to use an adapter. Converting VGA to HDMI isn’t complicated, but there are a few things you’ll need to keep in mind.

1. You’ll first need an adapter that converts from VGA to HDMI. These are widely available and relatively inexpensive.
2. You’ll then need to ensure that your computer’s video output is set to the correct resolution. Many adapters will only work at specific resolutions, so checking your adapter’s specifications before making any changes is essential.
3. Once everything is set up, connect the adapter to your computer’s VGA output and hook it up to your HDTV or monitor’s HDMI input.

7 Considerations When Running Dual Monitors With HDMI Cables

Below are key considerations when setting up dual monitors with HDMI.

• Graphics card: Make sure that your graphics card is up to the task of running dual monitors. The graphics card will have more than one port if it supports a multi-monitor setup.
• Monitors: Ensure that your monitors are compatible with HDMI. Not all monitors will work with HDMI, so check before you purchase.
• Cables: Make sure to purchase HDMI cables that are high quality and compatible with the resolution of your monitors. Though a standard HDMI cable can work on almost all monitors, it’s also important to check the speed to ensure that the quality of the display is high. While most HDMI cables are the same, there are some variations in HDMI cables that can catch you out.
• Resolution: Make sure that both monitors have the same resolution. If they don’t, your performance may be compromised, and you will need to adjust the resolution of each to match the one on your monitor.
• Refresh rate: The refresh rate of your monitors should also be the same. If they’re not, you can adjust them on your computer to be the same.
• Drivers: Make sure that your graphics card drivers are up to date.
• Power: Make sure that your monitors are receiving enough power. If they’re not, you may experience performance problems.
