It isn’t that difficult to connect two monitors to a laptop with one HDMI port. But you will require a few accessories like an HDMI splitter and HDMI cable.

Step 1: Checking Compatibility

The majority of Windows laptops currently support at least two monitors. However, you must confirm that your computer can support two more external displays.

Verify your operating system. Windows XP/7/8/10, for instance, and later versions all enable multiple monitors. You may check the internet to see if the OS you are using allows dual monitors.

Check the graphics card now. Most graphics card typically has at least two outputs, but to find out whether yours allows attaching two more displays, locate your graphics card and check the specs on the main manufacturer’s website. You may also try upgrading your graphics card if it does not enable adding more displays.

Step 2: Ports on your Laptop

Check the ports that are accessible on the computer and the displays, then locate the proper cords. There are two wires required. A computer or laptop should typically have one of the following four ports: DisplayPort, DVI, VGA, or HDMI. However, we will only need to think about the HDMI port for now.

You will need a DVI to HDMI converter to make them compatible if your laptop or monitor lacks an HDMI connector.

If you don’t know what port your laptop or computer has, have a look at the below image.

Step 3: Making Connections

As your laptop has only one HDMI port, you will need an HDMI splitter to have a pair of HDMI ports. This will work if your laptop only has one HDMI port, but you actually need two HDMI ports.

One end of this device connects to the single HDMI port on your laptop, while the other side has two HDMI ports, allowing you to connect two monitors to that port. This device has two outputs and one input.

Connect the cables for the first and second external monitors to the appropriate ports on your laptop.

To accomplish this, attach the first monitor’s HDMI cable’s end to the splitter output and the other to the monitor’s HDMI port (if your display lacks HDMI, use a DVI to HDMI or VGA to HDMI converter).

The second monitor should be connected to the splitter’s opposite end in the same manner.

Step 4: Configuring your laptop

Now you will need to edit the display settings. Go to the settings of your laptop and enter the display settings. For Windows 7 or 8 (click screen resolution). In display mode, there are three screens marked 1, 2, and 3.

In general, displays 2 and 3 are your external monitors, while display 1 is your laptop’s monitor. For each extra screen, you may create a separate configuration by choosing the display and then the content it will display from the “multiple display” option.

To modify your display settings, you have two choices. They are as follows

  • Duplicate the display across the two screens: The identical thing will be displayed on both screens using this option.
  • Spread your program windows across the two screens by selecting the option of extending the display. Professionals in Document Control typically employ such features so they may, for example, display papers on one screen and an EDMS or register on another.

Step 5: Extending display

Extending the display is the main reason for adding two computers to your laptop. Hence, to do this, follow the steps below.

  1. Select Extend desktop to this monitor under Multiple screens by clicking display 2, then click Apply.
  2. Select Extend desktop to this monitor under Multiple screens by clicking display 3, then click Apply.
  3. You can now utilize the three displays on your laptop after clicking OK to complete the configuration.
