Check Out How To Use Dual Monitors With Graphics Cards And Onboard

Individuals and businesses are looking for ways to use their computers more efficiently and productively.

While some have considered upgrading hardware such as RAM and hard disks, dual monitors provide a cost-effective way of achieving this.

With dual monitors, you can perform numerous tasks across multiple programs simultaneously. Your monitor displays images and video information with the help of the graphics card.

Some computers come with a dedicated graphics card, while others use integrated graphics referred to as Onboard. Onboard systems have their GPU built into the computer’s motherboard.

So how can you use dual monitors with graphics cards and onboard?

How To Use Dual Monitors With Graphics Cards And Onboard

You can do  this following the steps below:

1. Check your cable connections:

Before investing in a second screen, check the input/output panel for the computer’s cable connections. The idea is to ensure that your hardware can support a dual-screen setup with integrated graphics.

Your computer must have two display connectors. Decide on the spare port for connecting the new screen.

If your system has a non-integrated GPU, the GPU section should have the necessary stocks.

High-end PCs feature DisplayPort, HDMI, Thunderbolt 3, and even USB-C interfaces. If you’re using an old system, use the DVI-I port. Some people connect the second screen using a VGA connector, but it is not a suitable connector.

2. Ensure compatibility of new monitor:

After you’ve gathered enough information about your display ports, you should look into monitor screen compatibility.

Check the connectors on the monitor before you buy to be sure they’re compatible with your computer. To make the dual monitor experience as seamless as possible, use a screen with a thin bezel or none at all.

3. Go to your display settings:

Switch on the computer—Right-click on the home screen to open display settings. The linked display screen will now be visible in the list of connected screens.

If it doesn’t show up, unplug and reconnect the second screen connection.

Some monitors feature a wireless option that you can access by selecting “attach to the wireless display.”

4. Choose your display option:

How do you want to use the monitors? Select the secondary monitor at the top and then access the display settings.

Next, select Multiple Displays from the drop-down menu and review the options. Two options are available at this stage:

Extend the desktop: In this option, two screens will function as a single monitor.

Duplicate the desktop: This selection is helpful for training and teaching with the audience viewing one of the screens.

5. Optimize your display settings:

You can tweak your display settings to ensure both displays are appropriately set up for your needs. The users can change the resolution and orientation of both displays.

If you’re a videographer or photographer, you can use a better quality on the 4K secondary monitor screen and keep the main screen free of editing software options. The video output and GPU configuration determine the resolution settings.

You can also modify the brightness and turn on the night light mode to ensure seamless performance in darkened situations.

After you’ve completed the setup, we recommend that you browse tabs across various displays or use the drag-and-drop tool to enjoy the dual monitor setup.

Dual monitor usage is gaining popularity for the numerous advantages it brings. What are these advantages?

Advantages Of Using Dual Monitors

Multiple program use:

Dual monitors afford you the luxury of running many programs simultaneously. Individuals who work with a lot of programs will find this very resourceful. You can have a dedicated screen for your primary activity and use the other screen for other activities.

Easy to use:

A dual monitor setup is easy to arrange. All you need is a compatible second screen in addition to a primary screen with sufficient display ports. You do not need additional software to set up a dual monitor system.

Apart from setting it up, usage is also easy. You can drag and drop programs from one screen to another.

Improved productivity:

Dual monitors improve your productivity in many ways. For example, with a dual monitor setup, you can use one screen as a reference for information for the work you’re doing on the other screen.

Data sharing between apps is much easier on a dual monitor. You can drag images or files on one screen while the file explorer is open on the other screen.

Disadvantages Of Using Dual Monitors

Dual monitors may come with a lot of advantages, but it also has some downsides.

Increased workspace:

A dual monitor will take up more space than a single monitor. Unless you have ample space, which may be a luxury for many people, the result is a cramped working environment.


Setting up a dual monitor will cost you some fortune. Apart from the cost of getting a new monitor, you may need to buy extra display cords.

So, considering all these, between a dedicated graphics card and Onboard, which one gives the best results? Before we answer this question, let us consider the concept of graphics cards.

About Graphics Cards

Graphics cards help relay video and graphics information from the computer to the monitor.

A graphics card is like a smaller form factor of your computer’s motherboard. It is a printed circuit board with RAM and a processor.

Sometimes, people use graphics cards and graphics processing units (GPU) interchangeably. In reality, the GPU is a component of the graphics card.

Modern graphics cards are often the most sophisticated components in a computer, especially high-end graphics cards specialized for gaming and advanced graphics processing.

Graphics processing units come in two types: integrated and dedicated GPU.

Integrated GPU: An integrated GPU (also known as Onboard) is a graphics processor embedded into the motherboard. Integrated GPUs cannot be updated or removed.

Integrated graphics refers to a situation where you have both a CPU and a GPU on one chip. So, if you choose a computer with integrated graphics, that processor will manage both CPU and GPU tasks.

Integrated GPUs are found in laptops and low-cost desktop PCs. The visuals they produce are often slow and unsuitable for gaming or graphics development.

Dedicated GPU: A dedicated GPU comes with a discrete graphics card that fits into a motherboard expansion slot. This graphics card is removable, so you can upgrade to a newer graphics card when available, keeping your computer on par with current trends.

A dedicated graphics card is independent of your CPU and can process graphics-related information independently from your CPU.

Onboard Vs. Dedicated GPU – Which Is Better?

The major disadvantage of an Onboard graphics card is that putting a CPU and GPU on the same chip limits one (or both) of the CPUs. Computers that come with integrated graphics minimize their GPU use to have optimized CPU performance.

On the other hand, a dedicated GPU has a dedicated video random-access memory (VRAM) and cooling solution, so it has more potential processing power. Shifting the burden of processing graphics-related information to a dedicated GPU frees up resources for your CPU.

Consequently, a dedicated graphics card will not only deliver extra GPU power but will also lower the stress on your primary processor, improving your computer’s performance.

Using a dedicated graphics card improves a computer’s performance does not necessarily mean it’s suitable for everyone.

Onboard graphics are becoming increasingly powerful, and they can now provide more than adequate computing power for the average user.

Who Should Use A Dedicated Graphics Card?

You should consider two essential factors before deciding on the kind of GPU to use. These are your budget and line of work.

If you’re a serious gamer who wants to use high-end graphics, you need a computer with a dedicated graphics card.

A system with dedicated graphics is also ideal for graphic designers or 3D modelers. These activities require high processing power and they would exert considerable strain on computers using integrated graphics.

You can get a moderately priced good desktop that can efficiently handle your requirements. Laptops are pricier, although they are a better option for users who require more mobility.

Who Should Use Onboard Graphics?

Onboard systems are suitable for people who only need a computer or laptop for simple activities like surfing the internet, exchanging emails, and perhaps viewing movies.

Integrated graphics remains the alternative for gamers who desire a laptop but do not have a significant budget. Unfortunately, a cheap laptop with integrated graphics isn’t going to provide fantastic gaming performance.

However, if you play non-demanding games, you may still make the most of your Onboard system. You can also tune down your game settings to reduce strain on the system’s processor.


In conclusion, dual monitors provide more efficiency and productivity with increased and more convenient access to programs. Displaying graphics on monitors requires a graphics card.

Some systems come with a dedicated graphics card, while others have their graphics card integrated with the CPU in the computer motherboard. Integrated graphics are also known are Onboard.

To use dual monitors with the graphics card and onboard, check your computer’s display ports for dual monitor support.

If there are enough ports, you can now get a compatible second screen, connect it and tweak the display settings to suit your needs.
