I have a question regarding the Q90T as one of the "features" drives me insane and I cannot seem to find a way to turn this off.
Q90T connected to a Denon X2700 via HDMI3/eARC port
No other devices connected via HDMI
Every once in a while my UHD player (Sony) takes a bit longer to actually read an UHD - apparently the player doesn't seem to send an "I'm still here" signal during this time - after a (rather short amount of time) the Samsung will give me the dotted circle that he is looking for a signal and then an error message. Problem there is that it then switches automatically to HDMI1 (which makes no sense whatsoever to me). So I need to switch manually back to HDMI3 where the picture has "arrived" in the meantime.
Used the same disc on a Panasonic player (advantage of having two players) and saw that the Panasonic actually send a "Please wait" screen to the TV - so even if it takes longer the TV is fine as it is receiving a continuous signal.
I do know that it is caused by the way the player behaves, but it would also help me greatly if I could just tell the TV to not switch inputs automatically if he doesn't get a signal in time. As this is not really helping...
Also why the TV defaults to HDMI1 is beyond me (would make more sense to default to the eARC port) - but this also I cannot seem to change.
