Preparing the psvrplayer

You need to do two things before using psvrplayer:

1. Calibrate the vr helmet
   Place the vr helmet on a stable horizontal surface.
   Run the command:
   psvrplayer --calibration
   and follow the instructions
2. Select vr screen
   Run the command with the vr helmet connected and turned on:
   psvrplayer --listscreens
   The program will display a list of screens, select the appropriate one for your vr helmet and remember the screen position, for example: 1920×0
