A:AnswerHi CNAR, your 8K Q900TS TV will upscale non-8K content into stunning 8K detail and definition. Your 4K DVD/Blu-ray player is compatible and needs an HDMI connection. ^Val
A:AnswerI had it installed, but I was told by the sales person that my existing mount would work, as long as it would support the weight. I wound up buying a new one anyways to be safe.
Hope this helps

A:AnswerHi there - Samsung TVs are VESA Compliant and work with any wall mount or stand that is also VESA Compliant and designed for the TV's size. For your 75” TV, you would need a VESA bolt pattern of 400 mm x 400 mm. For an adjustable height mount of that measurement you may want to look into a stand or a wall mount designed specifically for placement above a fireplace mantel. ^Val
A:AnswerHi! The 75" Q900TS features three ways to connect to external audio devices; digital optical audio, HDMI ARC, and Bluetooth audio. Make sure your new or exisiting Macintosh audio system supports one of these three audio technologies for compatibility. ^Tim
A:AnswerHi there, there isn't enough information in your post, though it is overwhelmingly likely the system is partially or completely compatible. -Scott
