4. Then,  access your screen-sharing settings from your device. This can vary from one device to another.



5. Log into your Lü. Eg: Lu0247. If necessary, write down the requested password. This password will be displayed on your Lü screen.

Note: Click on Remember this device so that Reflector doesn't ask you for a password the next time you cast the same device.
