Unreliable, especially given the premium price.
I bought the TV in September 2018. By February 2020 (five months after the 1-year warranty expired), the screen had developed several vertical black lines running down the entire width. The TV was still watchable, but the lines were very noticeable in bright scenes. Then in December 2020, the TV completely failed and no longer turns on. Really disappointing that the TV failed so quickly. Given the premium price charged by LG and the relative newness of OLED panel technology at the time, LG should have provided a much longer warranty. I certainly won't be buying another LG TV, and I doubt I'll be buying any other LG products in the future.
