Going back to LG
I switched from an LG OLED to a Samsung S89C QD-OLED a couple years ago when I moved from 65” to 77”. I loved the Samsung, absolutely amazing picture, colors, brightness and blacks. No need for Dolby Vision with this light output.
Then just after two years, the Samsung had a board and or screen failure (super bright vertical green line). Complete loss - over two grand for a tv that’s is useless after only two years!
My 65 LG is still in daily use after more than ten years - no issues.
Never again leaving LG. I would recommend getting an extended warranty for any Samsung OLED.
