Usage:
```
monitordisplay -m MODE_NAME
# equals: xrand --output SYSTEM_SCREEN_NAME1 --primary --mode 1920x1080 --pos 0x0 --output SYSTEM_SCREEN_NAME2 --mode 1024x768 --pos 1920x0
monitordisplay -t
# equals: xrand --output SYSTEM_SCREEN_NAME2 --mode 1024x768 --pos 0x0 --output SYSTEM_SCREEN_NAME1 --mode 1920x1080 --primary --pos 1024x0
monitordisplay -m MODE_NAME2

# For removing the parameter "--off"
monitordisplay -m MODE_NAME2 -s
# equals: xrand --output SYSTEM_SCREEN_NAME1 --primary --mode 1920x1080 --pos 0x0 --output SYSTEM_SCREEN_NAME3 --mode 1920x1080 --pos 1920x0
