A:AnswerFour screws were in box. To mount on wall, I assume the wall mount came with or will advise which screws to use. Being I already had a wall mount up, I just used 4 screws provided to attach to TV.
A:AnswerWay too wide, almost as wide as the TV itself. I spent $35 of a stand with pivot, where I could also control the height above the stand.
NOTE: for smaller TV tables, it is possible to reverse the legs to make them point inward, instead of outward (works fine).
A:AnswerYou have to go into the settings for each individual app from the tv itself, if that makes sense. When you are watching Netflix for example, just hit the settings button and it will take you to settings for that app.
A:AnswerWell, if you get the Sony Bravia, you don’t need any other devices. Just run the internet cable straight into tv. Tons of apps and 4K streaming options right from tv :)
