Connected to Macbook, touch screen responds incorrectly?

Q1:I used a touch monitor with my MacBook. Why it responds incorrectly?

📌A:Mac OS doesn’t suppoet external touch monitors.
The cursor reacts when user touching the screen. However, the cursor’s location could be wrong and Mac OS doesn’t support touch gestures either.
The cursor may response on the main display instead of the external monitor while touching the screen. Mac OS doesn’t support touch settings and calibration function either.
If you want to use your Macbook with a touchscreen, we recommend installing Windows 10 Dual System on your Macbook to use Windows for touchscreen operation.
