You will need to purchase a graphic card that is capable of supporting multiple screens if your laptop does not already support multiple displays.

Additionally, in order to make the arrangement work, the Windows operating system on the laptop has to have support for a number of monitors. Multiple display monitors are supported by all versions of the Windows operating system, including XP, 7, 8, 10, and 11.

Graphics Or Video Cards On The Device Should Support Two Displays

The second need for the laptop is the installation of a graphics card that is capable of supporting multiple screens simultaneously.

How can one determine whether or not the graphics card in the laptop is capable of supporting multiple displays?

If you are using a laptop running Windows 10, right-click anywhere vacant on the screen. Navigate to the Display section of the system Information menu in the NVIDIA control panel.

You may locate the graphic card that your laptop uses, such as a GeForce MX 130, inside of it. GeForce GTX 1660 or about equivalent. Now, google your question.

Running Dual Monitor With One HDMI

Utilizing an HDMI splitter is the most straightforward approach of powering two displays from a single HDMI connector. Having said that, this will only be successful if you want the display to show the same material on all of the devices that are linked (duplicate content).

How To Run Dual Monitors With One HDMI Port

A kind of mediation device known as an HDMI splitter is a piece of hardware that has two or more HDMI ports. You need to inquire for an HDMI splitter at any local hardware shop, or you may easily locate one online. On the other hand, not all HDMI splitters are created equal. The challenge here is to choose the most appropriate one that is capable of transmitting both the data and the audio in the greatest possible quality and without any interruptions.

How to connect two monitors using an HDMI splitter?

A cable is already linked to an HDMI splitter when you purchase it. In order to connect two monitors, you must first connect one end of the HDMI splitter to the HDMI output port on the computer or laptop.

Now, switch to a different HDMI cable. Connect one end of this cable to the input port on the HDMI splitter, and the other end of the cable to the HDMI port located on the computer or laptop.

The configuration is going to look like this: a computer or laptop (output) an HDMI splitter a computer or laptop (input) (input).

Using HDMI Adapter

There is a difference between an HDMI adaptor and an HDMI splitter. You may connect two or more monitors with the aid of an HDMI adapter. You can choose to link them using an HDMI to DVI converter or an HDMI to VGA adapter, depending on your preferences.

You may use an adapter that converts HDMI signals to DVI if you want to connect a laptop to a computer display. To connect a laptop to a desktop, on the other hand, you will need an adapter that converts HDMI signals to VGA (as desktops usually have a VGA port at the back).

How to connect a laptop with dual monitors via an HDMI adapter?

You will need either an HDMI to DVI converter (if the external monitors you are using have DVI connectors) or an HDMI to VGA adapter in order to set up this configuration (if your external monitor has VGA ports).

To link them together, you must first attach one end of the adapter, which corresponds to the HDMI port on your laptop, to that port. After that, attach the other end of the adapter, which corresponds to the VGA or DVI connector on the first external monitor.

Now, in order to connect your laptop to the second external display, you will need to use a different connection that your laptop has a connector for (either a USB-C or a VGA cable). If you are using an adapter that has both a USB-C and a Thunderbolt port, connect the USB-C end of the converter to the USB-C port on the laptop. Then, connect the VGA or DVI cable that comes from an additional external display to the Thunderbolt side of the adapter. A connection using thunderbolt is much quicker than any other connection.

Now, follow the following steps:

  • start your laptop and right-click on an empty space
  • Go to Display Settings> Screen resolution (on Windows OS 7 and 8)

Go to the Display settings menu in Windows 10, scroll down until you find Multiple Displays, and then click the button labelled Detect to them. After that, go to the Advanced display settings menu.

  • There will be three monitors before you. Show 1 as the screen of your laptop, and display 2 and 3 as external displays, respectively.
  • You may choose additional displays by clicking the display 2 button. Select Extend Desktop to this Display, then click the Apply button. This will not duplicate the material on any of the screen displays; instead, you will be able to see distinct information on each of the three screens.
  • You should carry out the same steps with display 3 as well.
  • You are finished, just click the OK button.
  • Utilization of a docking station

Using a docking station is yet another option for operating twin displays via a single HDMI connector. A docking station is similar to a hub system in that it has many ports of different types. It gives you the ability to link a number of different devices together.

How to connect the dual monitor using a docking station?

If you want to use a docking station to operate dual monitors with an HDMI connector, check your external displays first to see if they have any ports accessible (it could an HDMI, DVI, or VGA).

Now, utilise a docking station that accepts USB Type C, which indicates that this device would make use of a USB Type C port as an output source. Connect the USB C docking station to the USB C connector that is located on your laptop.

Now, disconnect the DVI or VGA cable that is connected to the external display and insert it into the appropriate port on the docking station. The laptop and the external display will be joined together via this connection.

At this point, you should use an HDMI cable to immediately connect the laptop to an additional external display. Use a DVI or VGA cable in the docking station in addition to an HDMI cable if the external monitor you are using does not have an HDMI connector (depending on the availability of the port).

The connections between the three displays will be made at this time. To get both devices to cooperate, you need to carry out the identical steps on the laptop that you did with the HDMI adapter.
