App-Controlled LED TV Backlight — Smart Screen Sync & Music Sync Lights for Behind TV

Mobile app control with multiple modes, including music sync and screen-synchronized lighting. Compatible operation requires a TV BOX (similar to an APPLE TV box) or a third-party device — for example a gaming device such as PS4, a TV BOX, or another game console — that outputs to our box; our box then outputs to the TV to enable the synchronization effect.
