LG – 75″ Class 7S Series QNED AI Mini LED 4K Smart webOS TV (2026)

LG 75QNED7SBUA: 75-inch QNED MiniLED smart TV

The LG 75QNED7SBUA combines a 75-inch class screen, 4K resolution and webOS 26 in one TV. This model uses the Alpha 7 AI Processor 4K Gen9 and has a native refresh rate of 60Hz. Its 3 HDMI inputs let you connect external sources, while built-in smart features provide another way to watch. Its Mini LED backlight works with an LCD panel to control light across the screen.

Screen technology and picture detail

Mini LED backlighting uses small light sources behind the LCD panel. This model combines that backlight with Dynamic QNED Color (100% Color Volume certified) to present color and contrast in the picture. The 3840 x 2160 screen resolves fine detail in a native 4K source, such as textures in a film, lettering on a sports graphic or objects in a game. Source quality still matters: low-resolution or heavily compressed video cannot gain all the detail of a native 4K recording. Screen size is measured diagonally, so the 75-inch class designation should be considered separately from the cabinet width listed below.

Processing and HDR

The Alpha 7 AI Processor 4K Gen9 handles picture processing, with 4K Super Upscaling for lower-resolution sources. Upscaling fits the incoming image to the screen and refines its presentation; it does not change the original recording. Supported HDR formats are HDR10, HLG. An HDR film or game must be supplied in a compatible format to use its HDR information. Filmmaker Mode is included for a film-focused presentation. This combination gives you a choice between everyday viewing settings and a more film-focused picture when watching suitable content.

Refresh rate and gaming

The native panel refresh rate is 60Hz. Game Optimizer brings game-related settings together, and Auto Low Latency Mode can switch to a low-latency setting when supported by the connected source. Game settings can be selected to suit the source and type of play. The console or computer, selected input mode and cable must support the signal you want to use. A game’s rendered frame rate and the TV’s native panel refresh rate are separate specifications, so a high-refresh display does not make every game run at the same speed.

Smart TV and supported viewing

webOS 26 is built in, with access to compatible TV apps through LG’s smart platform. It supports Google Cast and Apple AirPlay for compatible casting or screen sharing. LG Channels is available for supported streamed programming. App selection, available programs and connected services depend on the region and service provider. Internet access, an LG account and separate service subscriptions may be required. The TV’s smart interface provides an alternative to using an external streaming player, while the HDMI inputs remain available for sources you already own.

Sound and audio connections

The built-in 2.0 channel speaker system is rated at 20W. The built-in speakers handle everyday program audio without requiring a separate sound system. Audio return is supported through eARC on HDMI 2. This gives you a route to a compatible external audio system when you want to build on the TV’s own speakers. The effect of surround processing depends on the program, listening position and connected equipment. Speaker-channel labels describe the hardware arrangement; virtual audio processing should not be confused with having separate physical speakers around the room.

Ports and wireless connectivity

There are 3 HDMI inputs and 2 USB inputs. Wireless connectivity includes Wi-Fi 5 and Bluetooth 5.3; an Ethernet input provides a wired network option. An RF input supports a compatible antenna or cable feed, with reception dependent on the signal available at your location.

Dimensions, weight and installation

Without a stand, the 75QNED7SBUA measures 65.71 x 37.91 x 2.84 inches in width, height and depth and weighs 48.72 lb. With a compatible stand fitted, the dimensions are 65.71 x 40.39 x 14.21 inches and the weight is 49.60 lb. Measurements are rounded conversions from LG’s metric specifications; a stand is not implied to be included. The VESA mounting pattern is 300 x 300 mm. Measure the available surface and cable space before installation. The panel-only depth does not describe the total depth once a stand or wall bracket is fitted.

Everyday controls and room placement

High Contrast, Gray Scale and Invert Colors are listed accessibility controls. LG ThinQ provides compatible phone-based remote functions. When planning the room, consider the height of the screen relative to your main seat and the position of bright windows. Viewing angle and reflected light can affect the image seen from a side seat.
