A:AnswerWe are about 10 feet away and have a 65 inch set. The OLED is so sharp, that we could have even gone bigger, but 65 is quite adequate. There is no distortion as you get close, so I would get a set as big as you can and that your budget affords.
A:AnswerYes. I purchased the Hamony remote to combine all others into one. I did pay to have the Geek Squad program all of the electronics to the Harmony. Would highly recommend the price for peace of mind to have done correctly.
A:AnswerYou may already have your answer, but 3D is the 3D technology that usually requires 3D glasses to watch the 3D movies. 4K is the technology that is considered super high definition. It's a step up from 1080p. Our OLED TV didn't have 3D but definitely was 4K.
