It comes with the flush-fit wall mount built in, and does not include a tabletop stand.

4K OLED Screen
The pixels of the Organic LED display are self-illuminating, adjusting independently, for true depth and colour gradation. This 4K OLED screen produces impeccably deep blacks, bright whites, and scintillating colour. This revolutionary technology has been mastered by LG for stunning picture quality, and from any angle.

4K UHD resolution with Dolby Vision HDR
This screen has four times the number of pixels than Full HD TVs, delivering stunning realism, natural motion and incredible detail. High Dynamic Range expands light, dark, and every colour in between for a picture that's closer to real life. This set supports multiple HDR formats including Dolby Vision.

a11 AI processor
Exclusive to select LG OLED TVs, this advanced processor, the brain of the TV, is tailored for OLED, ensuring premium picture and sound quality, delivering image enhancement through AI Super Upscaling and emotional precision through AI Director Processing. Plus, it upscales audio too for a more cinematic experience, whilst ensuring every word is clear thanks to AI Voice Remastering.

Extraordinary cinema and hyper-real sport experience
Laser-sharp pictures, crystal-clear sound and the deepest black levels. Filmmaker Mode and Dolby Vision HDR combine for exceptional colour and contrast, for a cinematic experience as the director intended. It also delivers the realism and intensity of the sports stadium, with uncompromised picture quality at any viewing angle, and the smoothest motion thanks to OLED Motion tech.

Dolby Vision plus Dolby Atmos sound
With exceptional colour and contrast plus 3D surround sound, Dolby Vision and Dolby Atmos audio together ensure full audio-visual immersion, providing awe-inspiring drama to every genre.

AI Sound Pro
AI Sound Pro enhances the audio to put you at the centre of the action, creating an immersive and absorbing atmosphere in any room.

Exceptional brightness with Brightness Booster Max
Brightness Booster Max comprises an advanced Light Boosting algorithm, plus Light Control Architecture, for amazing brightness – much brighter than conventional OLED - ensuring a stunning picture no matter how bright or dark the room. It’s complemented by Peak Highlighter, ensuring even brighter highlights for dazzling imagery.

Supreme gaming
Unleashing the potential of next-gen consoles, boost your competitive edge with 0.1ms response time and low input lag. It’s also loaded with pro-tools like 4K@144Hz, Variable Refresh Rate, Auto Low Latency Mode, and eARC as specified in HDMI 2.1, plus G-Sync, FreeSync, and Game Optimiser options.

webOS smart platform
LG's smart platform hosts a huge variety of the top streaming services, including Freeview Play, NOW, Netflix, Prime Video, Disney+, Twitch, and more*, while browsing and searching for what to watch is hassle-free. If you want to enjoy content mirrored from your smartphone, it supports AirPlay 2 and Chromecast, and hands-free voice control is also supported for ultimate convenience.

LG soundbar synergy
Pair with a compatible LG soundbar (sold separately) to enjoy a seamless, connected experience with enhanced sound. WOW Orchestra utilises TV and soundbar speakers simultaneously for an optimised experience. WOW Interface takes the hassle out of tuning your audio, using soundbar mode controls and accessible TV remote and on-screen menus.

One Wall design
The G45LW offers an ultra slim profile and built-in flush fit wall mount providing understated elegance, merging seamlessly into the environment while making a bold statement. It comes with a built-in flush fit wall mount, and does not include a tabletop stand (though one could be bought separately).

Please note: this TV is designed to be installed flush to the wall using the included mount. Therefore any plug socket or aerial cable directly behind the TV would need to be recessed into the wall.

Perfect partners
With TVs getting slimmer and built-in speakers getting smaller, choosing the right sound system is more important than ever. Soundbars enhance your TV's sound quality and add that extra audio punch to all your movies, games and TV programmes. More affordable and easier to set up than a full size speaker system, they don't compromise on quality either.

Don't forget...
If you want to connect your TV to a blu-ray player, games console, soundbar or soundbase then you'll need a HDMI cable.
