The LG G4 OLED is LG's flagship 4k TV for 2024. It replaces the LG G3 OLED and sits above the LG C4 OLED. Like its predecessor, it uses Micro Lens Array (MLA) technology for better brightness than typical WOLED panels, but unlike the G3, the G4's 83-inch model also includes MLA, although the super expensive 97-inch model doesn't. It uses the 2024 version of LG's webOS, and the TV has 60W 4.2 channel speakers built-in that can be virtually up-mixed to 11.1.2 using the α11 AI Sound Pro feature. We bought and tested the 65-inch model, but it's available in five sizes: 55, 65, 77, 83, and a massive 97-inch model. Unlike its predecessor, the 55-inch and 65-inch models now include a stand in North America, but the 77-inch, 83-inch, and 97-inch models still come with LG's Slim Wall Mount.
Our Verdict
The LG G4 is excellent for mixed usage. You get a top-notch gaming TV that's loaded with modern features and delivers clear motion, so it's a great choice to pair with modern consoles and PCs. You also get an amazing home theater TV that's sure to impress with both SDR and HDR content, and it's one of the few OLEDs on the market with the reflection handling and brightness needed to fight glare in a well-lit room. Furthermore, it has an incredibly wide viewing angle, so it's a great TV when you have friends over to watch sports.
Near-infinite contrast ratio for perfect blacks with no blooming around bright highlights.
- Incredibly wide viewing angle for a consistent image from the sides.
Good SDR brightness and excellent reflection handling makes it suitable for a bright room.

The LG G4 is amazing for a home theater. It has perfect black levels, so blacks are inky with no blooming whatsoever. It has excellent HDR peak brightness, so highlights really stand out in HDR movies and shows. You also get vibrant and lifelike colors in both SDR and HDR, and colors are very accurate overall. The TV has great image processing that gives you a clean-looking image for times you're stuck watching low-quality and low-resolution content, and HDR content has minimal banding and accurate brightness. Unfortunately, due to the TV's nearly instantaneous response time, there's noticeable stutter in movies and TV shows.

The LG G4 is good for use in a bright room. It has good SDR brightness, especially for an OLED, so it's bright enough for use in a well-lit room. It also does a great job reducing the intensity of direct reflections like a lamp placed opposite the screen, so you aren't distracted by pesky light sources. You do lose those inky black levels OLEDs are known for when you use the TV in a bright room, but they still remain deep enough that the image doesn't look washed out. Unfortunately, colors don't look nearly as vibrant as they do when using the TV in a dark room.
Good SDR brightness and excellent reflection handling makes it suitable for a bright room.

The LG G4 is very good for watching sports. Its incredibly wide viewing angle makes it suitable for watching the game with friends, as anyone sitting to the sides of the screen sees a consistent image. The TV has the brightness and reflection handling needed to overcome glare, so it's suitable for Sunday afternoon NFL games. You also won't be distracted by the dirty screen effect when watching sports with large areas of uniform color, so you can stay immersed in the big game. It also does a solid job upscaling and removing artifacts from low-quality content, so you get a clean-looking image. Furthermore, there's no noticeable blur or artifacts behind quick-moving players and objects due to the TV's nearly instantaneous response time and clean transitions.

Colors are well saturated and vibrant on this TV, so colors in your favorite games really pop out. It also has excellent HDR brightness, so highlights in HDR games really stand out against the rest of the image. Enabling Game Optimizer doesn't majorly impact image quality, so you don't have to worry about trading picture quality for the best performance. The TV has HDMI 2.1 bandwidth on all four ports for up to 4k @ 144Hz, making it an excellent TV to pair with modern consoles and gaming PCs.

Differences Between Sizes And Variants
We bought and tested the 65-inch LG G4 OLED (OLED65G4SUB), but our results are also valid for the 55, 77, and 83-inch models. The massive 97-inch model doesn't have the MLA focusing layer, so it isn't as bright as the smaller models. Note that the last three letters in the model number (SUB and WUA in this case) vary between retailers and individual regions, but there's no difference in performance. In the UK, you can also get the 55-inch and 65-inch models with a wall mount (LW) instead of a stand (LS).
| Size | US Model | UK Model | Stand or Wall Mount | MLA |
|---|---|---|---|---|
| 55" | OLED55G4SUB | OLED55G46LS | Stand | Yes |
| 65" | OLED65G4SUB | OLED65G46LS | Stand | Yes |
| 77" | OLED77G4WUA | OLED77G45LW | Slim Wall Mount | Yes |
| 83" | OLED83G4WUA | OLED83G45LW | Slim Wall Mount | Yes |
| 97" | OLED97G4WUA | OLED97G45LW | Slim Wall Mount | No |
Our unit was manufactured in March 2024, as seen on the label.
Popular TV Comparisons
The LG G4 OLED is an incredible TV and one of the best OLEDs on the market. It has very few direct competitors but shares a similar panel and overall performance to the Panasonic Z95A OLED. It's brighter overall than the 2023 LG G3 OLED, increases the maximum refresh rate from 120Hz to 144Hz, and has less banding. Unfortunately, it's also very expensive. If you want similar performance overall but don't need the extra brightness, the cheaper LG C4 OLED is a solid alternative.

We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
