What can I do if the pen nib is offset the cursor?

Windows OS:

1. Right click your desktop to enter Display settings.       
2. There are 1 and 2 in the top, you could click Identify to know what 1 and 2 separately represent.                                                               
3. Click 1(Computer), make Change the size of text, apps, and other items 100%, make Resolution recommended.                                         
4. Click 2(Coast 16), make Change the size of text, apps, and other items "100%", make Resolution "1920×1080（Recommended)".   
    
                          
   
   
5. Enter Tablet Setting from Start.
   
                              
   
   
6. In Mapping, select "Monitor 2"(Coast 16), Click Calibrate.   
   
                           

Mac OS:

1. Enter Quick Setup from the tablet icon of Task bar. 
                                        
   
   
2. Go to Region Setting and choose "Monitor 2”(Coast 16).     
   
                                                       
3. Click Default if the pen nib is still offset the cursor. 
   
                                  
   
   
4. If you want to adjust the pen yourself, click Calibrate. Default is more recommended.

Note:It is a normal phenomenon to have a slightly optical parallax when using the pen to draw in the monitor, because there is a thick glass between pen tip and pen touch area.
