2. Open Control Center:
   1. On iPhone X or later, or iPad with iOS 12 or later: swipe down from the upper-right corner of the screen.
   2. On iPhone 8 or earlier, or iOS 11 or earlier: w=swipe up from the bottom edge of any screen.
3. Tap Screen Mirroring.
4. Select the device you want to mirror to.
5. If asked for a password, please enter the one that appears on the TV screen.
6. Open the Ultimate Guitar app and enjoy the big screen experience!
