  • In the list of available displays, select the second monitor
  • Go to the secondary monitor’s Display Settings.
  • From the menu, click on Multiple Displays. From here, you can adjust the settings to your preferences.
  • At this stage, you can choose to either extend your monitor or duplicate your desktop. Both screens will function as a single screen with an extended monitor, while a duplicate screen will have the same information on two different displays.

On Mac:

  • On your home screen, tap on the Apple icon.
  • Select System Preferences > Display > Arrangement
  • In the main display settings, uncheck the mirror display box
  • A diagram on your main display will show the arrangement of your monitors. If the positioning is not in the correct format, locate the secondary display.
  • Click and drag the secondary display icon into the correct position.
  • The next step is to configure your new display. Click on Scaled and select the correct resolution for your monitor.

Tip: To get the best results, use native resolution for your display.

There are solid arguments for and against onboard graphics. How do they work? Are they better than dedicated graphics? Continue reading to find out more.

How Do Onboard Graphics Work?

Onboard graphics or Integrated Graphics Processor (IGP) is present on almost all computer motherboards.

This chip serves the same role as a video card. Both of them can access and analyze graphical data and display high-definition information on the monitor’s screen.

The CPU usually transfers the graphics load to this section of the motherboard. You will find the graphics chip soldered to the motherboard.

This graphics chip comes with limited functionality and does not require a cooling fan to function.

Advantages Of Onboard Graphics

Smaller form factor:

Onboard graphics cards are smaller than separate graphics cards. They are small because they do not require an independent cooling facility and share many CPU elements.

Onboard graphics are also less in weight. As a result, onboard graphics in laptops and other portable devices are pretty handy.

Because of its lightweight and low processing power, onboard graphics can only meet the consumers’ basic graphics requirements.

Power efficiency:

Onboard graphics consume less power. It uses a fraction of the power of dedicated graphics cards.

By consuming less power, onboard graphics help to extend the battery life of portable devices.

Reduced heat generation:

Since onboard graphics consume less power, they also generate less heat than dedicated graphics. This advantage is beneficial for laptop users.

It does not require a separate cooling system:

Onboard graphics do not require different cooling hardware since they generate little heat. The CPU cooling machinery is adequate for onboard graphics.


Onboard graphics are an integral part of the motherboard and CPU, so you do not need to purchase them separately. Also, there would be no spending on upgrades as you cannot upgrade or change them.

They use little power and, as such, are cost-effective. For this reason, laptop makers prefer onboard graphics to offer users products with more battery life.

Disadvantages Of Onboard Graphics

Usage limitations:

Due to their compact size and limited power, onboard graphics have limited functionality.

At best, you can use them to view high-definition videos and play simple games. However, you need a dedicated graphics card to view videos in 4Kor 3D or play high-end real-time games.

Fixed functionality due to not being upgradeable:

Onboard graphics chips come permanently soldered to the motherboard. You cannot upgrade them to a new or improved version.

Therefore, your computer’s graphic functionality remains fixed.

Not adequate for gaming:

High-end gaming is not possible with onboard graphics. Because of its limited processing power, it cannot seamlessly handle high-resolution graphics.

However, users can play certain basic level games and some moderate games at reduced settings with onboard graphics.

Are Onboard Graphics A Good Fit For You?

Deciding whether you are okay with onboard graphics or need to invest in a dedicated graphics card depends on your usage.

If you use your PC for simple tasks like document processing, surfing the internet, or exchanging emails, onboard graphics are perfect for you. Those tasks do not put severe pressure on your computer’s CPU and will not negatively impact performance.

However, if you’re into serious gaming, graphics processing, or 3D modeling, onboard graphics may not suit you. These tasks are intensive and require sufficient processing power.

Using onboard graphics in these circumstances will significantly strain the CPU and cause your PC to lag. You will have to invest in a dedicated graphics card to get the best out of your computer.
