If your computer has only one VGA port and you want to connect two monitors, there are a few options you can consider:
- Use a VGA splitter: A VGA splitter takes the video signal from a single VGA port and splits it into two, allowing you to connect two monitors. However, both monitors will display the same thing, as the splitter does not increase the video capabilities of the computer.
- Use a VGA to DVI adapter: If one of your monitors supports DVI input, you can connect it using a VGA to DVI adapter. This will free up the VGA port for the other monitor.
- Use a switchable display adapter: A switchable display adapter allows you to switch between multiple displays, depending on your needs. You can connect the first monitor to the VGA port and the second monitor to the switchable display adapter, which can be connected to the computer through a USB port.
- Use a dedicated graphics card: If you need more video outputs, you can install a dedicated graphics card that has multiple VGA, DVI, or HDMI ports. This will give you more flexibility and allow you to connect multiple monitors to your computer.
Note that the options available to you may vary depending on the specifications of your computer and the monitors you want to connect.
If you’re still somewhat puzzled, don’t worry I have more explanations and illustrations in this article.

Can I Have Dual Monitors With Only One VGA Port?
Yes, 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. Blue plastic is commonly used to color label them. Because VGA is analog, it should only be utilized if the monitor and the computer lack DVI connectors.
Having two displays may significantly boost productivity. You may enjoy this dual-monitor arrangement even if you have one VGA connector.
Please remember that a VGA splitter is insufficient. Therefore, you must verify your PC’s specifications to see whether it can support a two-monitor arrangement. You must get a graphics card supporting this capability if it cannot.
When you do that, just put your VGA wires into a VGA splitter to enlarge your screen.

How Do I Add a Second Monitor to One VGA Port?
Change the Video Card – This is a long-term answer, but it can be costly.
Replace the old video card with one that supports two VGA ports. This may necessitate time, experience, and money. As a result, we propose you replace the graphics card if you are prepared and confident that you will honor the two VGA ports.
Get a VGA Splitter – The VGA splitter is a tiny electrical device that can instantly solve your problem! This isn’t too pricey, and the setup process isn’t that tough, either.
Can VGA Splitter Extend the Display?
In most cases, the splitter can simply replicate or mirror the same desktop or user interface. Splitters did not expand desktop programs in 2012 when Windows XP was the prevalent operating system worldwide. They required video cards with desktop extension services for desktop splitting to be possible.
You’ll need more than a VGA splitter and at least two monitors to accomplish the desktop extension. You’ll also need the software and a suitable video card to enable the splitting to take place. Otherwise, the most you’ll get from your splitter is screen mirroring or duplication. You can do screen extensions or flip between single-screen, split-screen, and desktop extension modes on and off after you have a video card, a VGA splitter, and monitors.
Splitters did not independently extend desktop programs in 2012 when Windows XP was the dominant operating system. For desktop extensions to be possible, they required video cards having desktop extension services.
What Type of Splitter Do I Need for Dual Monitors?
HDMI – An HDMI splitter divides a video signal so it may be displayed on two displays. You don’t have to buy the entire system when you obtain the second monitor. All you need is a splitter, and you’re ready to go.
The splitter allows the user to send a signal to another screen, but up to 10 screens. As a result, an HDMI splitter can have more than two outputs for separating the signal from a single device. An HDMI adaptor is an ideal splitter if your device does not have HDMI ports.
Before selecting an HDMI splitter for a dual monitor, you must first establish the number of displays you intend to connect to a single source. A splitter with several inputs is ideal if you wish to broadcast material on numerous monitors or TVs. A 1×2 splitter is an excellent choice for displaying through dual monitors.
An HDMI splitter separates a video signal so it may be displayed on two different screens. The splitter allows the user to signal up to ten other displays. An HDMI adapter is an excellent splitter if your device lacks HDMI ports. A splitter with multiple inputs is excellent if you want to broadcast content to many monitors or TVs.
The Best HDMI Splitters You Can Choose
Avedio Links 4K HDMI Splitter For Dual Monitor – Avedio supports video and audio streams, making the connection as simple as plugging in. The splitter is activated, providing the best signal with little latency and operating effectively over extended distances.
OREI HDMI Splitter – OREI is a splitter with exceptional features and capabilities that have graced the market. The splitter has a 4k display to guarantee the highest resolution for gaming and streaming. OREI is operational, allowing it to service two monitors that are physically separated from one another. The two-input splitter works flawlessly to provide the greatest possible display while utilizing the primary, universal HDMI connector.
VGA – The second type of splitter for dual monitors is the VGA splitter. VGA ports, considered ancient hardware by today’s standards, may still be found on most PCs and monitors. This version does not support audio and has a maximum resolution of 640 × 480. Although modern VGA may provide resolutions of up to 1080p, it still lacks audio capability. VGA ports are always blue and have a trapezoid shape.
DVI – Third is the DVI splitter. A DVI port’s video capabilities can match or exceed an HDMI connector’s. The most notable distinction is that HDMI connections can transport audio, whereas DVI cables cannot. DVI ports became less common as HDMI connectors got increasingly prevalent. DVI ports are white and have a 24-pin connection and a flat-pin connector.
DisplayPort – DisplayPort is new on the block, capable of astounding resolutions and frame speeds, and it’s sweeping the PC industry by storm. DisplayPorts are rounded rectangles with one corner chopped off, similar in size to HDMI ports. DisplayPort may handle resolutions and frame rates of up to 8k at 60 frames per second (FPS), 4k at 144 FPS, and 1080p at 240 FPS. The last is the DisplayPort Splitter, which allows you to connect monitors to one DisplayPort.
How to Connect Three Monitors to One Computer With One VGA Port?
There are a bunch of ways through which you can connect three monitors to one computer that has only one VGA port.
Firstly, you need to check for various video ports on your computer.
Even though your PC only has one monitor output, you can use an external multi-display adapter to operate three separate displays.
If you don’t want to spend the money on an external multi-display adaptor, you may acquire a USB to HDMI adapter. You’ll need one adapter for each extra monitor, so if you already have one, plug two of these adapters into your PC’s USB ports, connect a couple more monitors to the other end, and you’re done! You get a three-monitor extended desktop.
You may connect up to three extra displays to your computer via a docking station. Simply connect your computer to the docking station using the included USB host connection, and then connect your additional displays to the docking station’s DisplayPort and HDMI connectors.
Even though your computer only has one VGA connection, you may attach up to three monitors in various ways. You may require an external multi-display adapter or a USB to HDMI converter. You’ll need one adapter for each additional monitor, so if you already have one, connect two of these adapters to the USB ports on your PC.
Many job circumstances need the use of many monitors. Whether a programmer or an artist, using two monitors increases your productivity and brings your work to life, dual monitors will boost the efficiency with which you can utilize your computer. The additional screen area is also ideal for video conferences and meetings, allowing you to retain your workflow on one screen and your video chat on another.
Each person on the call can be seen clearly, with a complete second screen. It is not difficult to connect a second monitor with only one VGA port. The preceding article reviewed all conceivable methods for connecting two monitors to a single computer with only one VGA connection.
