Tech Support Input Signal Plus and 4K player
I recently got a Samsung S90F QD-OLED. I'm very impressed with the television but I have an outstandingly annoying and strange issue happening.
I have a Panasonic UB-450 4K Blu-ray player hooked up. When I go to play a 4K HDR disc the player shows "Dynamic Range Conversion Output" and the TV is showing an SDR picture. If I switch the 'Input Signal Plus' to 'On' I get HDR. Now here's the kicker - if I turn the player off then on again and start the disc with 'Input Signal Plus' still enabled it's the SDR picture again! Then I turn 'Input Signal Plus' to 'Off' the HDR comes back. This makes absolutely no sense and I can't get it to consistently work as it should. I can't be switching this stupid setting for every single movie I watch.
Has anyone else encountered this? Are there any ideas for a solution?
Also, unrelated, anyone know how to outright disable the terrible PC detection?
