This is probably something which I hope can be fixed through some setting.
- On my previous TV, an old 2018 Sony, the screen would blink 2-3 times rapidly after initial boot as if it was synching with the TV and then all would be fine.
- On my new Samsung S84F, if the box is turned on after the TV is turned, the screen will constantly intermittently blink (about every 30-45 seconds or so) and go dark for a second (it actually seems to impacting the data as well since video will start over the last 2-3 seconds like you sometime get with a problematic channel) . It sometimes goes completely off synch before getting the main menu screen and the TV no longer sees the box as and HDMI input. If I make sure the Classic is on prior to turning on the TV, it generally is fine.
I tried playing around with the video settings and disabling all HDMI CEC options, this did not seem to have any impact. I go through an HDMI switch and my HW800 soundbar, I am not sure this plays any role in this since this was fine with the previous TV and has not changed.
