    LG 100” TV

    Once set up, the LG TV clarity and sound from the soundbar & speaker is like sitting in a theater. You can hear the sounds of the actors and sounds in nature and other characters precisely clear in all scenes. Very realistic, 3D sound effects. AMAZING!

    Amazing 100” LG TV

    This is such an amazing tv and for the price it’s crazy. The picture quality is incredible. I have it mounted in my basement in my man cave and takes up the whole wall. It’s super thin for the size. The brightness is incredible but it also nice because with the lights off it doesn’t make the room super dark.

    I think the new features on the remote are great.

    I purchase two TVs, I have bought a new tv in more 10 years. I got a 77 inch for the living room and enjoy the quality. Then a 100" for the basement for the kids to watch and plat games on. Im very happy. Thanks

Questions & Answers

  • How much does this TV weigh?

    Best Buy's specifications for the LG 100" Class 84B Series QNED evo AI Mini LED 4K Smart webOS TV (2026), Model # 100QNED84BU, list 150 .1 pounds for Product Weight With Stand, and 145.3 pounds for Product Weight Without Stand...^Ivan.

  • Where in the back of tv can an outlet be placed?

    If you are going to be mounting the LG 100" Class 84B Series QNED evo AI Mini LED 4K Smart webOS TV (2026), Model # 100QNED84BU, then the best practice is to place the outlet hidden directly behind the screen, usually in the upper left or upper right corner. This placement keeps cords completely out of sight and ensures easy access to the plugs. Never place the outlet in the dead center of where the TV will mount, as the mounting bracket or hardware will cover it. You can install the outlet slightly above and to one side of the center studs, or you can install a recessed media box to allow plugs to sit flat against the wall without interfering with the TV's tilt or mount. While there is no single electrical code requiring an outlet at TV height, the National Electrical Code (NEC) dictates general room spacing (an outlet within 6 feet of any point). If adding or modifying outlets behind a TV, it is highly recommended to consult the Electrical Code Requirements for Outlets or hire a licensed electrician...^Ivan.

  • Does the slim mount come with the tv?

    Unless Best Buy is offering a bundle package for the LG 100" Class 84B Series QNED evo AI Mini LED 4K Smart webOS TV (2026), Model # 100QNED84BU, and a wall mount bracket, the TV does not come with a slim mount. It would have to be purchased separately...^Ivan.
