Hi herf, I too am trying to apply the flux filter from my MacBook to my Samsung TV using AirPlay however the flux settings are not carried over (and the TV screen is bright enough to wake up the neighbors)! Wondering if you may have found a way to wirelessly carry over the flux settings? Thank you for any thoughts you be be able to share. Steven
