Connect to Macbook, the touch screen respond incorrectly?
I used Gechic touch monitor with my MacBook. Why it respond incorrectly?
Mac OS doesn’t suppoet touch monitor.
The cursor will react when user touching the screen.However,the cursor’s location could be wrong and it doesn’t support the gesture.
The cursor always response on the main display instead of second display while touching the screen. Mac OS doesn’t have the alignment 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.
