It’s better to have two monitors rather than having one. Therefore, the iPad can be used as a Second monitor. You can share and extend the same desktop experience to your iPad with the help of a Sidecar. If Sidecar doesn’t do justice to you, you can also use third-party applications to connect the iPad as a second monitor. Since iPad does not have a larger display than Mac, you will not have a wider screen view. However, you can connect your iPad to Mac to experience smooth scrolling.
Quick Guide: From your Mac, launch System Preferences > Set up Sidecar options > Select iPad > Choose Use As Separate Display.

How to Connect iPad as Second Monitor [For Windows]
There are a few more options to use the iPad as the second monitor for Windows.
- Duet Display
- Air Display
 Duet Display
We can use Duet Display to connect the iPad as the second monitor for Windows. Duet Display uses a 30-pin cable which we use for charging the iPad. It makes the connection faster and loads the videos in no time. In case you are going to connect it via your Wi-Fi, then the connection would be slow and lagging.
 Air Display
Air Display is the first app to connect or convert the iPad to a monitor even before Duet Display. The main drawback of Duet Display is that it is not TKO registered. Thus, it loses its popularity.
iDisplay is another option to make your iPad as the second monitor for your windows. You can go for iDisplay if you are looking out for better options. But it is so expensive when compared to Duet Display and Air Display.
This way, you shall connect the iPad to your Mac or windows in simple steps using some applications. You can experience your iPad display just like your desktop but on a smaller display. Although the applications you choose to connect iPad to windows are paid for, it’s worth the money to get an additional display for a better experience.
