A:AnswerI use a Vizio soundbar. It works, but if I fastforward my DVR'd show the soundbar quits, and I have to turn it off and back on to hear it. Didn't happen with my old Samsung.
A:AnswerThe One Connect cable can be run through the wall without issues. I have my set up done with all cabling through the wall including the soundbar cabling. Everything works great!
A:AnswerThere's no RCA inputs for this TV, you have many options here, an RCA to HDMI converter. The games will look blurry though. I'd wait for the NES classic to come out and get reviews on that. There is a device called the framemeister that upscales old school games beautifully. Then again it might be worth finding an old CRT television for this experience.
A:AnswerYes Samsung's TVs are capable of connecting to Bluetooth speakers/Headphones this year and should work with the gaming headphones Bluetooth wise
A:AnswerI can answer the second question. There is a little glare on my set, however it's not overwhelming by any means. It's not a matte finish so there's just a slight glare, but nothing that takes away from the TV. After a day of using it, I didn't notice it.
A:AnswerSettings>Special Viewing Mode>HDR on. This TV will automatically detect a UHD but won't turn on the HDR setting by itself.
I chose to use different settings for each source and would recommend that to you as well.
A:AnswerYes you can view Youtube TV content either by connecting the TV to your network (direct or wireless) and using the built in Youtube app, or you can stream through a device like Roku
