Hello there, right now I have a Sony X806E, LED IPS TV from 2017. Has worked great for the last few years but the low contrast and the lacking black uniformity has become very annoying. So I had in mind buying a QLED TV but I consider OLED to be superior in 2021. I've been lokingthe LG BX, I'm pretty sure I can find it for 1000 dollars where I live. But I have some concerns, the first one is HDMI ARC. I have a Sony receiver that has HDMI ARC, works great with a Sony TV but I'm not sure how it's going to perform with a different TV. The next concern is the OS, my family and are very happy with Android TV. And my final is concern is not bad but I'm curious, how good does the processor upscales 1080p content, I have a collection of Blu Rays and DVD's, so that's important for me. Also about audio output, has anyone got any trouble with Dolby Digital 5.1 in apps, I'm not using a Atmos at the moment? Any other comment or experience is appreciated, thanks in advance.
