A:AnswerBest Buy offers a couple weeks for free depending on when it was bought (i.e. holiday purchases have a larger window). Samsung has a 1 year manufacturer warranty though included on the purchase, but you have to go through them instead of Best Buy. Best Buy also offers additional warranties if you want to pay more for them.
A:AnswerAbsolutely. Hanging it takes two people though. And make sure your cables are are plugged in before you hang it when you use a low profile mount, to avoid taking it off again just to plug something in.
A:AnswerIt’s a marketing gimmick. This TV does not have wide viewing. Colors and brightness wash out when viewed from off-angle. It’s common for the majority of LED TVs, except LG’s sets which use a different panel structure (but have poor contrast levels). Only the Q80R and above sets have actual wide-viewing that lets you sit off-axis without affecting the picture too much.
