I've got a 65" LG OLED. The picture is insane, better than any movie theater. I haven't had wifi connection problems, but sometimes the sound does not work correctly. I would have to power it off completely, meaning unplug it since the power button is more like an idle button. Then whatever got corrupted in the audio chip is cleared out and it works normal. Also, make sure you upgrade your HDMI cables to the high bandwidth HDMI 2.1 versions. Otherwise you will not get the full HDR10+ or Dolby Vision from your bluray. I don't think the PS4 supports Dolby Vision so if you want that work you will need a bluray player that supports it like the Sony x700. Amazon prime has some stuff in HDR10+ and Disney+ has some stuff in Dolby Vision so you can watch the Mandalorian in all of its glory. You will know if Dolby Vision is working if you see the Dolby Vision logo pop up in the corner when the movie starts. It's really something on another level when you get the Dolby Vision working since there are no compression artifacts or color banding. It's like watching the movie played out in real life through your window. I would also recommend getting a legit 5.1.2 or more surround sound system with Dolby Atmos. Sound bars just don't cut it. I had to upgrade my receiver to the yamaha Rx-v685 to get dolby atmos, but im using a mix of speakers from bower wilkins sides and subwoofer, paradigm center and surrounds, and klipsch atmos speakers. If I was looking to get a new set of home theater speakers the entry level Klipsch atmos sets are great, no real reason to get anything super high end just for movies. My only regret now is not getting an 85" OLED instead.
