A:AnswerSankofa - The QN90A does not have a built-in camera. You can disable the voice assistant feature by going to Settings > General > Voice > Bixby Voice Settings > Voice Response > Off. Then open Voice Wake-Up Settings and set to OFF. You can also disable Alexa and Google Assistant. ^Gina
A:AnswerBob - The QN84A TV features 40 Watt 2.2 Channel sound. The QN84A also features Object Tracking Sound Lite which virtually tracks objects moving across screen and strategically places sound around you. The QN90A features 60 Watt 2.2.2 Channel sound as well as Object Tracking Sound Plus (OTS+) which utilizes 6 speakers to place sounds exactly where they appear on-screen and optimizes sound based on each scene. Another benefit gained when stepping up from the QN84A is Ultra Viewing Angle which makes every seat in the house a great one. Engineered to reduce glare and enhance color, this feature delivers a vibrant picture no matter where you sit. ^Gina
A:AnswerHi Mackie - The QN90A TV features Auto Volume, which automatically adjusts the sound to a certain level when changing channels or switching to another external input. Go to: Settings > Sound > Expert Settings > Auto Volume = On. ^Gina
A:AnswerHi InSearchofAtmos - The QN90A TV absolutely supports Atmos pass-through! You can set the TV to allow Dolby Digital+ with Atmos streams that are input from external devices. Set to ON if the audio device connected via HDMI (eARC) supports Dolby Atmos. eARC will allow uncompressed Atmos. As long as your external device supports Atmos, you can pass-through Atmos via eARC without issue. ^Gina
A:AnswerThere is a general standard of 1.5 to 2.5 times the size of the tv (use inches, convert to feet). That makes the 75 inch 9.5 ft to 15.5 feet. That being said....my sofa is at 10 feet--the TV is above the fireplace. We did a SLIGHT tilt. The kitchen is in back of the small living/family room and separated by a half wall. I watch from there often and the back of the kitchen is over 15.5 and the picture is great. Hope this helps.

A:AnswerHi looking, the QN90T is compatible with our new Slim-Fit Wall Mount. No-Gap wall mount will not work as it uses a dedicated mount built into the TV. ^Val
