Does anyone here not engage local dimming? The reason I'm asking is I bought my TV during during Black Friday, so the weather was cool, and so was my home. Now, it's starting to be spring here, so things are warmer, including my home. I'm guessing the changes in environmental conditions have affected my tv a bit. Basically, I'm noticing more sounds coming from it due to thermal expansion and contraction of the parts. I'm very sensitive to this, so I've been troubleshooting it. After a few pings during the initial warm up, I've noticed more pings occurring when the screen transitions from very bright to dark, and vice versa, which I've traced back to local dimming activating and changing the temperature of the unit. I also notice pings when switching from SDR content to HDR as the unit warms, and vice versa when the unit cools.
To make a long story short, I've been playing around with deactivating local dimming to avoid this quick changes in lighting and temperature. I don't notice much of a visual effect in SDR content, especially since I keep my backlight low at 10. But, with HDR content, it has a more profound effect, mainly in the letterboxes. One good thing, I suppose, is no more blooming!
Has anyone else noticed the thermal expansion and contraction sounds in their units? Am I just a cursed individual?
