10 years? LG C2 in RTINGS test showed faint signs of burn-in after 1200 hours. That’s just 5 months of 8 hours/day use. I don’t plan on using my monitor for 10 years but sure as hell I want to last it more than 5 months.

Here’s the benchmarks: link. CPU - Fairphone 5: 1100 / 2800. Apple A11 CPU (iPhone 8/X): 1092 / 2352.
I don’t quite get where sustainability comes from. You can buy similar (hardware-wise) Samsung with 4 year support for twice as cheap. 300$ difference is enough to change battery and screen even at overpriced Samsung’s official repair service.
