How much does this TV weigh?
Answered by LG Digital Customer CareBest 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?
Answered by LG Digital Customer CareIf 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.
