Using two monitors has become a typical setup, especially when people started realizing how convenient it is to see all their apps in one glance. 

You don’t have to be annoyed switching from one window to another. Plus, you even increase your productivity! 

If your computer or primary monitor has two VGA ports, then you can just go ahead and connect one VGA adaptor to each port and get going. 

Unfortunately, not a lot of computers have two VGA ports. But don’t worry, there is another way for you to have a dual monitor setup. 

Keep reading to know how to set this up. 

Does a VGA Splitter Allow an Extended Desktop?

There is some disagreement about whether a VGA splitter can enable an extended desktop. To put it another way, you can use your secondary display as an extension of your primary monitor.

If you’re only using a VGA splitter, then no, you can’t extend your primary monitor to the second monitor. All it can do is mirror the first monitor.

However, if you have a video card that allows for extended monitors, then you can automatically extend your view to the second monitor.

As a best practice, we recommend checking your graphics card, video card, and your PC’s specs so that you can determine if it can support dual monitors.

For some, the maximum their PC’s specs can do is a dual monitor setup. If you need a third monitor to extend to, you need a graphics card that allows for two or more video outputs. 

Should You Connect Two Monitors to One Computer with One VGA Port?

You can have dual monitors with one VGA port. Connecting the monitor to the desktop requires video interfaces such as Display Port, DVI, VGA, or HDMI. The VGA, or Video Graphics Array, is the standard used to link computers to displays.

When connecting two monitors to one computer with one VGA port, a few things to consider. The first is the resolution.

The VGA port can support resolutions up to 2048×1536, so make sure your monitors are set to a resolution that the VGA port can handle. The second thing to consider is the refresh rate. 

When Is It Necessary to Connect Two Monitors To One Computer: 

When selling gadgets, it is necessary to connect two monitors to one computer to get the best possible price. This is because buyers are willing to pay more for a complete set-up they can use immediately.

By including both monitors in the sale, you are giving the buyer everything they need to use the gadget immediately. This is the best way to get the most money possible when selling gadgets.

How do you Connect Two Monitors to One Computer with One VGA Port?

If you have a computer with only one VGA port, you can still connect two monitors to it by the following methods:

 1. Using a USB Adapter or Docking Station:

If you’re looking to boost your productivity by using two monitors, you’ll need to connect them to your computer. You can use a USB adapter or docking station to connect the second monitor if your computer only has one VGA port.

To connect a second monitor using a USB adapter, connect the adapter to your computer’s USB port and then connect the monitor to the adapter.

If you’re using a docking station, connect the second monitor to the docking station and then connect the docking station to your computer.

Once the second monitor is connected, you’ll need to configure your computer to use it. In Windows, you can do this by going to the Control Panel and selecting “Display.” Under the “Settings

 2. Using VGA Splitter:

If you have a computer with only one VGA port and want to connect two monitors, you can use a VGA splitter. First, connect a VGA cable from your monitor to the VGA port on the video card.

Then, connect the other end of that cable to the “out” display port on the splitter.

Next, connect another VGA cable from the “in” port of the splitter to the VGA input on your primary monitor. This will allow you to use two monitors with one VGA port.

 3. Through KVM Switch:

A KVM switch is a great way to connect multiple computers to one monitor. To do this, connect your computer to the KVM device and your monitor to both devices.

You can switch between each computer with a button press or hotkey combination.

This is especially useful if you have multiple computers set up in your home or office and need to access them all on one monitor.

What Type Of Splitter Do I Need For Dual Monitors?

You can use an HDMI splitter for dual monitors to replicate contents from your laptop, game console, or cable box to other monitors. The splitter helps maintain the source device’s high resolution and quality audio.

When choosing an HDMI splitter, you’ll need to consider the number of HDMI ports you need and the resolution and refresh rate of your monitors.

Some splitters also come with additional features like remote control and audio extraction.

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

Even though your PC only has one monitor output, you can use an external multi-display adapter to operate three separate displays. This is ideal for those who want to increase their productivity by having multiple screens or for gamers who want to create an immersive experience.

You will need an external multi-display adapter and three VGA cables to connect three monitors to one computer with one VGA port.

Once you have all the necessary equipment, connect the adapter to the computer and the monitors to the adapter.

You may need to adjust your computer’s display settings to utilize all three monitors properly; otherwise, you should be up and running with three displays!

If you want to avoid spending money on an external multi-display adaptor, you may acquire a USB to HDMI adapter. This will allow you to connect three monitors to your computer with only one VGA port.

Connect the HDMI adapter to your computer’s USB port, and then connect the three monitors to the adapter.

You will then need to configure your computer’s display settings to extend your desktop across all three monitors.

Are there Other Ways to Connect Two Monitors with One VGA Port?

Yes, there are! But these methods no longer use a VGA splitter. 

Here are the two popular alternatives to try. 

Connecting via HDMI

HDMI cables are quite useful, especially for newer laptops and home entertainment equipment. Most monitors will also feature an HDMI port.

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

You must go to ‘Display Settings’, same as you would when connected via VGA. This lets you rearrange your monitors based on how they are set up.

For HDMI connections, you can choose to mirror or extend your screen.

Connecting via USB to HDMI

You will still need an HDMI cable for this, but you will also want another accessory: a USB to HDMI adaptor.

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 connector via a USB cable.

All you need to do is plug the USB end into a USB port on your computer. Then, connect an HDMI cable (which is not generally provided with an HDMI adapter) to the adapter and the monitor’s port.


Does The VGA Splitter Reduce Quality?

A VGA splitter is great for watching the same video on both monitors. Its output image quality can be the same as the original signal.

However, it is essential to note that a VGA splitter does not reduce the quality of the original signal.

How Many Times Can You Split VGA?

Due to the limitations of the VGA analog signal, only two displays can be properly cloned and maintain optimal resolution through power state changes.

This is because the VGA signal is not digital and can only be split a limited number of times before the signal begins to degrade.

For this reason, splitting the VGA signal more than two times is not recommended.

Can I Connect 2 Laptops With A VGA Cable?

No, you cannot connect two laptops with a VGA cable. The VGA port on the laptop only provides video output, so there is no logical connection between the two laptops.

If you want to transfer data between the laptops, you can connect them via LAN. If you want to use the other laptop’s screen as a secondary display, it’s not possible.

What Is A VGA Splitter?

A VGA splitter is a device that allows you to connect multiple monitors or displays to a single VGA video output on a computer or other device. It essentially takes the VGA signal from the computer and splits it into multiple signals, each of which can be sent to a separate monitor or display.

VGA splitters are typically used in situations where you need to display the same video content on multiple monitors or projectors, such as in a conference room or classroom setting. They can also be used for gaming or other applications that require a larger viewing area or multiple displays.

Is VGA Both Input And Output?

VGA can be both an input and an output, depending on how it is being used.

In general, VGA is an output format that is used to send video signals from a computer or other device to a monitor or display. The VGA output is typically a male connector that plugs into a female VGA input on the monitor or display.

However, there are also situations where VGA can be used as an input. For example, some older televisions or projectors may have a VGA input that allows them to display video from a computer or other device. In this case, the VGA input would be a female connector that accepts a male VGA output from the computer or other device.

Can I Use Laptop VGA Port As Input?

No, you cannot use a laptop VGA port as an input. The VGA port on a laptop is typically an output that is used to send video signals from the laptop to an external monitor or display.

While some laptops may have a DisplayPort or HDMI port that can be used as an input to connect to other devices, the VGA port is not designed for this purpose. It does not have the necessary circuitry to accept video signals from other devices and display them on the laptop’s screen.

Quick Summary:

Having two monitors can be a great productivity improvement. And even if you have one VGA port, you can still get to enjoy this dual-monitor setup. 

Keep in mind that a VGA splitter is not enough, so you have to check your PC’s specs to know if it can accommodate a dual monitor setup. If it can’t, you have to buy a graphics card that allows for this feature. 

Once you have that, you can just plug your VGA cables into a VGA splitter, and you can now extend your screen.
