HDMI ULtra HD Deep Color - No signal
I have an OLED65B7P (software update 06.00.05) connected via HDMI through a Denon AVR-X1300W receiver to a firestick and a Tivo Bolt.
The problem is that ever since an update a few months ago the TV automatically switches to "Deep Color" on its own, and then it typically only works for a while before the TIvo stops working (get "no signal") and I have to go and once again manually reset the HDMI channel to disable deep color.
Is there any way to disable this automatic switching to deep color? Or any ideas on how to keep it working? I did update my HDMI cable to the Tivo but that didn't help.
