If you can't buy a sub -display, you should substitute a tablet with "Duet Display"

Easy to achieve "Plus another display"

　MacOS Catalina has provided a function called "SIDECAR" that allows iPad to be used as a sub -display.In this case, the body side is a Mac and the tablet side is an iPad.

　The "Duet Display" introduced this time is similar to this "SIDECAR", but the combination pattern is abundant.PCs support Windows as well as Mac, and tablets can also use Android in addition to iPad.It is unknown whether there is a need, but it is also possible to connect the Android tablet to the Mac to make a sub -display.

　Here are some concrete connection procedures.This time, as an example, on the Windows machine (ThinkPad X1 Carbon 2019), iPad (12).Introducing the procedure for connecting 9 inch iPad Pro).

　That said, there was no procedure to explain in order.First, install the utility on the Windows side.Then install the application on the iPad, connect it with Windows and cable, and start.With just this, the Windows screen is also displayed on the iPad.

　Since Windows is recognized as a normal display, it is possible to freely adjust the duplicate and adjust the resolution with the display settings on the Windows side.Of course, it also supports vertical display.

　There is also a function to set resolution and frame rate on the app side, which is given priority over the Windows side.The resolution of the tablet is generally higher than the notebook PC, so if you change the display to 200%, the balance should be better.
