I have a 75inch q60r that I purchased recently. Sometimes when I watch something, most recently some UHD content through Amazon, the TV will randomly dim the whole screen momentarily and then brighten back up again. It's quite jarring and very annoying.
I've turned off the Eco Sensor, the ambient light detection, and any other feature that I thought might have been casing it, but it's still happening. I chatting with Samsung support earlier, and their solution was to reset the picture settings, but that did not fix the issues either.
Does anyone else have this problem and can you please advise me as to how to solve it as it's really starting to become an issue.
I'd be more than happy to look into this further for you. Could I have your full model code and serial number via private message?
