A:AnswerHi Joseph. In theory, the faster the refresh rate, the smoother the picture on a TV, but to answer your question, what two important things you need to understand about video are that you cannot add detail beyond what is already in the source footage and that source footage is never greater than 60 Hz. Not to get into a lengthy discussion about interlacing, 2:3 pulldown and upconversion, American TVs have displayed 30 (actually 29.97) frames per second and functioned at 60 Hz since the introduction of TV. Between interlacing and frame pulldown, the process doesn't attempt to add information to the picture. It's simply converting it to function on the TV because it wouldn't work otherwise. Once the TVs refresh rate goes above the rate of the content you're watching, it interpolates new frames between the frames transmitted to the display at 60 frames per second to fill in the spaces by generating the best "middle" frames to stick in the cracks. These new frames are made by combining and processing the data of the frames surrounding them, generating the images the TV thinks it should draw between the images it's told to draw by the media. You're looking at more individual pictures as the screen draws them, but these pictures weren't on the television signal that the screen is receiving; the TV is generating those additional pictures itself. Motion blur is something that has always afflicted LCD TVs, (All LED LCD TVs are LCD TVs) and they tend to display a distinct blurriness during fast movements, although current TVs have done a great job of eliminating that. Choppiness or "tearing" might still be noticeable, especially in sports and video games or in content that has a lot of fast, horizontal panning of the camera, and that is when higher refresh rates can help. This higher refresh rate is what known as motion interpolation and is what is called TruMotion 120Hz on our LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700. It can produce a surreal effect when watching movies and television shows and can make footage look strangely fast, so you need to know when to use it and when not to use it. As a general rule, if what you're watching involves seeing real peoples' faces as they talk, disable TruMotion so you don't get what is known as the "soap opera effect". If what you're watching involves seeing real people run into each other (sports), or fake people attacking each other in an artificial environment (video games), keep Trumotion on...^IFV
A:AnswerIn order to watch Netflix on the 55UJ7700 tv , you need an internet connection either by wi-fi or wired into the LAN port on the set a and a Netflix account. The "smart " in the tv allows you to use just the tv to get different online viewing options without having to buy another device. As far as Netflix to local channels, the remote has a Netflix button to get you there. The display ad picture for the tv shows how all the viewing choice look on the bottom of the tv when you hit the RECENTS button on the remote. As far as the OLED /LED decision, consider a Ford vs.a Ferrari. Both can drive you to the movies, what is your budget to get there?

If the functionality of Alexa is what you are seeking for a new tv than the two options above are what you are seeking.
On the other hand if you are looking for a tv that can run all your accounts like Hulu, Amazon Prime, Netflix, YouTube etc. any smart tv will do. It all depends on what interface works best for you.
Hope this helps. Feel free to ask if you have anymore questions.
