Hello,
I have a Panasonic 65-DXW904 television and the settings are fine because i also use a HiMedia Q5 Pro en the settings never change !
My problem is that in settings i put the deep color mode on YcbCr420 10Bit but when i watch a movie or turn the Egreat A5 Off and go back in settings the deep color mode has changed BACK to YcbCr420 8Bit !!!!
It NEVER stay's on 10Bit !!!
With the HiMedia Q5 Pro this was also the problem but after a firmware update the problem was solved so thinh it is also a firmware problem with the Egreat A5

?
Can someone help me or know if i am right about this is a firmware error

Greetings from Holland and keep up the good work i really LOVE my Egreat A5 !!!
