Meanwhile, the same things are happening to all of you, thus the one issue that comes to mind is “how to connect a second monitor with only one vga port?” Because the availability of VGA ports is a major concern for most users. However, sometimes the setup is a simple process in which you simply plug the second monitor in and it starts working. 

So, today we’ll go through how to connect a second monitor with only one vga port, making your life easier without having to struggle. Now, keep reading to find out how to do it.


A single VGA port is found on many computers. However, this isn’t to say that the desktop can’t be extended. When you discover that your computer only has a single VGA port, you have two options: replace the video card with one that supports two VGA cables or utilize a VGA splitter with a USB port. The VGA splitter requires a lot of power, which can be provided by connecting the USB to a computer’s USB port.

Replace the video card.

Replace your old video card with one that supports two VGA ports. This may necessitate the investment of time, expertise, and money. So, if you’re up for it and confident that you’ll be able to do justice to both VGA ports, we recommend upgrading your video card.

Yes, this is a long-term solution, but it can be quite costly.

What Is The Best Way To Setup This VGA Splitter?

After you’ve received your VGA splitter, follow the steps below to set it up and connect two monitors to one computer:

  1. To begin, turn off your computer completely. Disconnect your monitor’s VGA port after that.
  2. Take the dual VGA cables and plug them into the female ports of the splitter you bought. Insert their male ports into your two monitors after that.
  3. It’s important to note that your VGA splitter will only have one cable. This should be plugged into the VGA port on your computer.
  4. Your VGA splitter will come with a USB cable that you should plug into your computer’s USB port.
  5. Now turn on your computer with two monitors.

Are there any other options for connecting two monitors using one VGA port?

Yes, there are! However, a VGA splitter is no longer used in these ways.

Here are two popular options to consider.

Connecting via HDMI

HDMI cables are quite useful, particularly for newer PCs and home cinema systems. An HDMI port will be found on the majority of displays.

If you have an extra HDMI cable, simply plug one end into your computer’s HDMI port and the other into the HDMI port on the second monitor.

You must go to ‘Display Settings’, same as when connected via VGA. This allows you to rearrange your displays based on their current configuration.

You can opt to mirror or extend your screen when using HDMI connections.

Connecting via USB to HDMI

An HDMI cable is still needed, but you’ll also require a USB to HDMI adapter.

This device is great if your laptop lacks an HDMI connection because it allows you to connect your computer or laptop to a second monitor with an HDMI port via a USB cable.

Simply plug the USB end into your computer’s USB port. After that, connect the HDMI adapter to the monitor’s port using an HDMI cable (which isn’t generally provided with an HDMI adapter).

How Do You Set Up The Two Monitors?

The dual extended desktop can now be configured now that the two monitors are connected. Do you want to learn how to do it? Then continue reading.

  1. Select Control Panel from the Start menu. Then select Personalization from the drop-down menu.
  2. After that, select the Adjust Screen-Resolution option from the drop-down menu. This will enable you to set the monitors according to your needs.
  3. To see your two monitors, select the Detect option from the drop-down menu. Numbers 1 and 2 will be assigned to them. Select the Extend Displays option after clicking the Multiple Displays tab. Be aware that this will enlarge your original monitor’s view.
  4. If you want the two displays to mirror, however, you must select the Duplicate Display option. You can rearrange your monitors by dragging their icons if you have chosen the Extended Display option.

Here’s a hint: if you have two monitors, you’ll need to modify the resolution and orientation of one of them. This is accomplished by choosing each monitor and then altering its resolution and orientation. If you wish to see some graphs or photographs in portrait format and others in landscape mode, this is beneficial.


Finally, Having two displays can help you work more efficiently. You may enjoy this dual-monitor arrangement even if your computer only has one VGA port.

Remember that a VGA splitter isn’t enough; you’ll need to examine your PC’s specifications to see if it can handle a two monitor arrangement. If it can’t, you’ll need to upgrade to a graphics card that supports this feature.

After that, you can simply put your VGA wires into a VGA splitter and extend your screen.
