A:AnswerThe salesman told me the picture of this TV would be better a darker room where the Samsung I was looking at would be better for a brighter room. My living room is located in the back of my townhouse so it doesn't get any direct light. The salesman was right!
A:AnswerYes, it does include apps. Netflix, Prime video, Disney+, and LG Channel are buttons on the remote and you can download others from the app store.
A:AnswerNot sure, but I use the ones that are screwed on the back of the TV itself (the screws that are covering to mounting holes). So far so good. I have been inspecting the wall mount here and there just making sure that nothing is coming loose. Its sitting firmly for a month now and I swivel the mount/tilt it and it is still on strong. Hope that helps. I took some pictures to show: the screws, the mount I’m using as well as the space between the mount and the TV.
