A:AnswerHello GolferTom,
The HW-Q850T would work best with the 75Q900TS. You will be able to use Q-Symphony which is a new level of acoustic immersion accomplished through collaboration between Soundbar and TV speakers. Any wall mount bracket that supports 75" TVs will work, main difference will be if you would like the option to tilt or move your TV. For Cables needed I would recommend a high quality HDMI to get the best performance from your TV. Please check out BestBuy.com.

A:AnswerHello Dellis220, The 75Q900TS can be wall mounted using a variety of mounts that utilize a VESA Standard of 400mm x 400mm. The 75Q900TS is not compatible with the No Gap Mount or the One Connect Box. Check out compatible wall mount options at Best Buy: https://www.bestbuy.com/site/searchpage.jsp?st=75%22+mount&_dyncharset=UTF-8&_dynSessConf=&id=pcat17071&type=page&sc=Global&cp=1&nrp=&sp=&qp=&list=n&af=true&iht=y&usc=All+Categories&ks=960&keys=keys ^Celina
A:AnswerHi GolferTom! The Q900T features more advanced contrast technology with a Direct Full Array rating of 32x and Quantum HDR rating of 32x. These features mean improved detail in dark scenes, and more realistic highlights in the bright ones. The Infinity Screen also adds to your experience by taking the picture from edge to edge without any distractions featuring the near-invisible bezel. ^Tim
A:AnswerHi Sam, you can connect your MacBook Pro via AirPlay or using a USB-C to HDMI cable. For specific resolutions supported with your MacBook, please consult with Apple. ^Gina
A:AnswerI asked the same question of the 85" 950 and 900, and I see the answer. Definitively NOT worth the extra $3000. From what I understand the One Connect has proven faulty and the 1 inch versus .6 is certainly not a deal breaker. I would expect a substantially better picture for that kind of money.

A:AnswerHey DaveO - The 75Q900TS can not use the No Gap Mount. You can use any mount available on BestBuy.com as long as its VESA 400 x 400 . https://www.bestbuy.com/site/searchpage.jsp?st=tv+wall+mounts&_dyncharset=UTF-8&_dynSessConf=&id=pcat17071&type=page&sc=Global&cp=1&nrp=&sp=&qp=&list=n&af=true&iht=y&usc=All+Categories&ks=960&keys=keys . ^Jason
