LG OLED77M5PUA: 77-inch OLED evo smart TV
The LG OLED77M5PUA combines a 77-inch class screen, 4K resolution and webOS 25 in one TV. This model uses the Alpha 11 AI Processor 4K Gen2 and has a native refresh rate of 120Hz. Its Zero Connect Box has 3 HDMI inputs that let you connect external sources, while built-in smart features provide another way to watch. The Zero Connect Box sends video and audio wirelessly to the OLED screen. Both the TV and box still need a power connection.
Screen technology and picture detail
Self-lit OLED pixels can switch off in dark areas, without a separate LCD backlight. Brightness Booster Ultimate is part of this model's picture system. 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 77-inch class designation should be considered separately from the cabinet width listed below.
Processing and HDR
The Alpha 11 AI Processor 4K Gen2 handles picture processing, with Alpha 11 AI Super Upscaling 4K 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 Dolby Vision, HDR10 and HLG. An HDR film or game must be supplied in a compatible format to use its HDR information. Filmmaker Mode is included. 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 refresh rate is 120Hz, with variable refresh rate up to 144Hz. 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. NVIDIA G-SYNC and AMD FreeSync compatibility are included. 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 25 is built in, with access to compatible TV apps through LG's smart platform. Google Cast and Apple AirPlay support compatible sharing. LG Channels provides supported streamed programs. 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 4.2-channel speaker system handles program sound. Dolby Atmos is supported for compatible content. HDMI 2 supports eARC for a compatible soundbar or receiver. 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
The Zero Connect Box provides 3 HDMI inputs and 2 USB inputs. Wireless connectivity includes Wi-Fi 6E 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
The panel measures 67.4 x 38.8 x 1.0 inches in width, height and depth and weighs 78.3 lb without a stand. The Zero Connect Box measures 9 x 4.8 x 9 inches. A wall bracket is included; a tabletop stand is not included. The VESA 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
The included MR25 Magic Remote controls the smart platform. LG ThinQ supports compatible phone-based remote functions. Place the Zero Connect Box in direct line of sight, no more than 30 feet from the screen and below its wireless receiver. Keep the box out of an enclosure so the wireless link has a clear path. This placement requirement matters when choosing a shelf or media unit. 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.
