How to connect two monitors to computer with only one HDMI port

Here in this comprehensive article, we will describe how to connect dual monitors with one HDMI port. Sometimes you need to display what you’re doing on a second screen for various reasons. All that’s required is a simple connection of your computer to a display through an HDMI cable, and you’ll be all set.

2 Ways To Run Dual Monitors With One HDMI Port

1. Utilizing HDMI And Other Display Ports On Your Computer Simultaneously

Most GPUs have many display ports. DisplayPort, DVI, VGA, and HDMI are computer display connectors (HDMI). On modern PCs, HDMI is most popular, followed by VGA. Older desktops have only DVI and Display Ports.

So, if your computer has an HDMI connection and any of the following ports, you may utilize them to show two displays. Before using two display ports at once, check two things:

Be sure the secondary port on your computer is compatible with the monitor you intend to use. If your computer has a DVI port, you might not see many new DVI displays; same with VGA and Display Port. To save the hassle of purchasing an adaptor, be sure both your computer and your monitor have parallel connections.

You may connect a PC with HDMI and DVI to two HDMI-only monitors. In this instance, you’d need a DVI to HDMI adapter or an HDMI to DVI cable.

Check the manufacturer’s website to see if your graphics card supports multiple displays.

Just hit the Start button, enter dxdiag, and then head to the Display tab to learn your graphics card’s official name and manufacturer.

If your graphics card supports Multi-Monitor, a straightforward Google search should guide you to its information.

Steps To Connect Two Monitors With One HDMI Port And Another Kind Of Display Port

  • First, you’ll need to insert your HDMI cable into your computer’s port to hook up your first monitor.
  • You’ll need to connect the monitor to the other end of the HDMI wire and turn on the screen.
  • Connect the second display by inserting the HDMI adapter into the second display’s corresponding connector.  If you are not using an adapter, connect the cable’s end to the port on the computer.
  • Connect your HDMI cable to the adaptor by plugging one end into its HDMI port.
  • Connect the other end of the cable to the appropriate connector on display. This might be an HDMI port or another type.
  • On your computer, right-click a blank area of the desktop, and then, depending on the version of Windows you’re using, choose Screen Resolution or Display Settings.
  • The pop-up window would show you three images of monitors numbered 1, 2, and 3. Screen 1 is the computer’s default display or the laptop’s associated screen.
  • You may tap any display to decide what you want to do to the show on it, like duplicating it, expanding it, or disconnecting it. You may also change the screen resolution and direction to run dual monitors.

2. Using Display Splitters With One HDMI Port

In some conditions, your computer may not have multiple display ports, your graphics card may not support multiple screens, or you may only wish to use your single HDMI port. To use a single HDMI port, you need a splitter.

An HDMI splitter sends the video signal from your computer’s single HDMI Port to several display devices.

These devices have one video input port and numerous outputs; a splitter may have up to 16 outputs. Following are some steps to utilize splitters:

  • Step 1: Connect the splitter to your computer’s HDMI port. Some splitters require an HDMI cable and a power source to function; others merely need to be hooked into a computer’s HDMI port.
  • Step 2: Connect two HDMI cables to each monitor you want to use
  • Step 3: Connect the HDMI wires to the splitter’s output ports.
  • Step 4:   Press Windows+P to expand or duplicate your display.


So, the simplest solution is to connect one monitor to an HDMI port and the other to any other available connector. In this manner, a separate device for supporting multiple displays is unnecessary. However, these methods depend on your secondary monitor and computer using the same port.
