How To Connect Two Monitors To One Computer With One VGA Port?

You won’t realize how much you’re missing when you work using a single monitor until you’ve tried using two or more monitors for your normal computer needs. But, how to connect two monitors to one computer with one VGA port? Using two monitors has become standard, especially once people realize how useful it is to be able to see all of their programs at once.

Switching from one window to another does not have to be a chore. Plus, it will be more productive as a result! To use two monitors, you can use an extended desktop to mirror your primary desktop or have two different outputs on different monitors.

If your PC or primary display has two VGA ports, simply attach one VGA adaptor to each port, and you’re ready to go.

Unfortunately, not many computers are equipped with two VGA ports. But don’t worry, there is another option to set up a dual monitor configuration for you.

How to connect two monitors to one computer with one VGA port?

With two monitors, you may increase the information on your primary desktop or deal with different sorts of output on each monitor.

Many monitors do not contain an HDMI cable, so you will most likely have to purchase one separately. Some desktops and monitors have dual ports and may be powered by USB. When using adapters, a variety of alternative combinations are conceivable.

Although the monitors may come with VGA or DVI cables, HDMI is the most common connector for most office twin monitor setups. The cable, on the other hand, is effective and ensures that your setup runs well. A VGA splitter has one VGA male connector on one end and two female connectors on the other. It looks like the letter ‘Y.’

One of the most efficient ways to create a dual monitor connector is to use a VGA (Video Graphics Array) splitter. The cord is specially engineered to bridge the gap between two displays while using only one computer connector.
Another option is to replace your computer’s video card entirely so that it can support not one but two wires.

However, if you’re on a budget and want a better choice, a VGA splitter is the way to go. But remember to take into consideration that it requires a significant amount of power to operate.

How to connect two monitors to one computer with one VGA port When the computer has a Single VGA port by default

A single VGA port is found on many systems. And when your computer only has a single VGA port, you have two options:

  • Replace the video card with one that supports two VGA cables.
  • It utilizes 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.


The splitter is frequently used by businesses and professionals in disciplines such as graphic design to create a two-monitor setup. Gamers also prefer dual monitors since they may enlarge their screens or use both screens at the same time.

The main benefit of using this cable is that it frees up other computer ports for your keyboard, mouse, and other peripherals. It eliminates cable clutter while providing a safe, high-functioning connection between the monitors.

You’re just delivering a single visual stream to all the monitors. So very little quality gets lost.

High-resolution programs on both screens may experience a minor degradation.

Setting up a VGA Splitter

  • Step 1: The first thing you should do after you have a VGA splitter is switch off the monitors. If your main display is a computer, you should also turn it off.
  • Step 2: Connect one VGA cable to your computer’s VGA port. If you have a PC desktop, the port is located on the back of the CPU.
  • Step 3: Tighten the screws until the VGA cable is securely attached to the port.
  • Step 4: Once that’s done, connect another VGA cable to one of the female connectors. Connect the other end of the cable to the back of your monitor and secure it.
  • Step 5: Apply the same procedure to the other female connector on the VGA cable that connects to your second monitor.


You may now switch on your computer and monitors after tightening all of the connections.

How to set up the expanded desktop

  • Go to Start > Control Panel > Personalization tab > Adjust Screen Resolution option.
  • You will now be able to select the solution that best suits your requirements.
  • When you press the “Detect” button, you should see two monitors labeled “1” and “2.”
  • Select “Extend Display” if you want an extended view of your display or “Duplicate Display” if you want both screens to mirror each other.

If you have the “Extend Display” option enabled, you can drag the icon and rearrange the monitors.

You may wish to modify the direction and resolution of every monitor if you have more than one. This is accomplished by choosing a certain monitor and altering its angle and resolution. This feature comes in handy when you wish to see some photographs or charts in landscape mode and others in portrait mode.


Having two displays can help you work more efficiently. Even if your computer only has one VGA connector, you can still enjoy this dual-monitor arrangement. 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. Once you’ve got that, all you have to do now is hook your VGA wires into a VGA splitter and extend your screen.
