A:AnswerNot sure what you mean but if you mean how do you use it. Just hit the house button on remote hit Netflix and set it up with your password and such.
A:AnswerYes it comes with a basic remote. No screws do not come with a tv when you buy it. The screw come with the mount. So if yours didn't you may wanna return the mount. The tv does have threads on it so you can use screws to mount it to the base.
A:AnswerI think you just need to play around with the picture modes. I like Sports for sports and Cinema for movies and TV shows. Sometimes, depending on the show, the ADP (I think that's what it is) is the better choice. It does help to switch back and forth depending on what you are watching at the time.
A:AnswerIt has component in the back and a input for cable / antenna (your basic coax cable) so yes if it has obe of those but picture quality will be really terrible. VCR redolution is going to be low and you will be stretching an image to be larger so quality will be pixely.
A:AnswerYes, it can. Xbox support HDR10, just as this TV set. As long you turn on the setting in the XBOX console to HDR on. It can stream any HDR content from the builtin app, HDMI and USB source.
A:Answeryou can listen to music from a usb stick with this tv however not all usb memory anf hard drives are compatible with this tv nor are all formats of audio or video files. that said it is a great tv
