Awesome TV and excellent Best Buy customer service
This was my first OLED and I am very impressed; plus the screen size is perfect for our new home theater. This was definitely the "icing on the cake" for finishing up the home theater project/remodel. Best Buy was great to work with. I originally had a different kind of TV arrive and it was broken in the box, and Best Buy was awesome to work with on getting it sorted out. I ended up returning the broken TV and exchanged it for this one instead, and I am very happy. I'm impressed with the Best Buy staff on how they helped answer my questions and helped me with getting the other tv returned. Back to the TV review, this TV is very clear/sharp, has very black contrast and with the picture being so realistic while watching movies, it's almost like you can reach out and touch the object that you're watching; it's truly an amazing TV. We've been a fan of Samsung TVs for many years, in fact we have one Samsung TV that is 11 years old and still works, so we know we made the right decision to go with Samsung. I'm running my sound through a receiver for home surround sound, but while I was testing everything I just temporarily used the built-in speakers that come with the TV, and I'm very impressed with how good it sounds given how thin this TV is. Thank you again Best Buy, your customer service made this a very pleasant experience.

OLED!!
TV is great. 77" was smaller than i was looking for but getting an OLED vs QLED was the best choice I've made. The colors are so vibrant and crisp, the screen is only 1/2" thick and it looks amazing on my wall.
