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, this year's 83-inch model also includes MLA, although the super expensive 97-inch model doesn't. It's available in five sizes: 55-inch, 65-inch, 77-inch, 83-inch, 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. 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.

Differences Between Sizes And Variants

We bought and tested the 65-inch LG G4 OLED (OLED65G4SUB), but it's also available in 55, 77, 83, and 97-inch sizes. 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).

Compared To Other TVs

The LG G4 OLED is an incredible TV and one of the best OLEDs on the market. It increases the maximum refresh rate to 144Hz, is brighter overall than the G3, and has less banding. Unfortunately, it's also currently a lot more expensive than its predecessor. Unless you need the small upgrades that it brings with it, your money is better spent on the cheaper LG G3 OLED while it's still available. If you want similar performance but don't need the extra brightness, the cheaper LG C3 OLED or the LG C4 OLED are very similar in most other categories.

For more options, check out our recommendations for the best OLED TVs, the best gaming TVs, and the best TVs for watching movies.

LG G3 OLED
55" 65" 77" 83"

The LG G4 OLED and the LG G3 OLED are very similar TVs overall, but the G4 is a bit better. The G4 gets brighter in HDR, so highlights stand out more on it, and it also maintains its brightness much better in Game Mode, so you don't have to trade in performance if you don't want a decrease in brightness. On top of that, the G4 has better HDR native gradient handling, so there is less banding in colors, and it supports 144Hz, so it's better for PC gamers looking to take advantage of their high-end graphics cards.

LG C3 OLED
42" 48" 55" 65" 77" 83"

The LG G4 OLED is better than the LG C3 OLED. The G4 gets brighter overall, so it overcomes more glare in a bright room while watching SDR content, and highlights pop more in HDR content. The G4 also maintains its HDR brightness much better in Game Mode, so you don't have to trade in brightness for performance when gaming. The G4 has better color volume, so it can display colors brighter, and there is less banding in colors. Finally, the G4 supports up to 4k @ 144Hz, so it's the better option for PC gamers with high-end graphics cards.

Samsung S95D OLED
55" 65" 77"

The Samsung S95D OLED and the LG G4 OLED are both top-notch TVs, but there are some differences. The LG gets brighter in SDR, so it overcomes more glare in a bright room while watching SDR content. The LG is the better option if you regularly watch low-quality streams or DVDs since its low-quality content smoothing does a better job. The LG supports Dolby Vision and DTS audio, so it's the better option for those who collect 4k Blu-rays or for those who want to take advantage of Dolby Vision from their favorite streaming apps. On the other hand, the QD-OLED panel on the Samsung provides a wider color gamut and better color volume, so colors are more vibrant, lifelike, and brighter in HDR content. The Samsung includes the Slim One Connect Box, which is good for those looking for a versatile way to plug in their devices, and its matte coating does a better job at eliminating reflections in a bright room, albeit at the cost of image quality.

Sony A95L OLED
55" 65" 77"

The Sony A95L OLED and the LG G4 OLED are both incredible TVs, but there are some differences. The LG gets a bit brighter overall, so highlights stand out a bit more in HDR content, and it overcomes a bit more glare when watching SDR content in a bright room. The LG also maintains its brightness better in Game Mode, so you don't have to trade in brightness for performance. The LG is better for gaming overall due to its HDMI 2.1 bandwidth on all four ports, up to 4k @ 144Hz, and lower input lag. On the other hand, the Sony can display more vibrant, lifelike, and brighter colors due to its wider color gamut and better color volume, and there is less banding in most colors.

Samsung S90D/S90DD OLED
55" 65" 77"

The LG G4 OLED and the Samsung S90D/S90DD OLED are both amazing TVs, but there are some differences worth noting. The Samsung has a wider color gamut, so it can display more vibrant and lifelike colors, and it has better color volume, so it can display brighter colors. The S90D also has no noticeable banding in colors, while the LG does have some banding in certain colors. On the other hand, the LG has better low-quality content smoothing, so it's the better choice if you regularly watch DVDs or low-quality streams. The LG also supports both Dolby Vision and DTS audio formats, which is great if you're looking to get the most out of your 4k Blu-ray collection. On top of that, the LG has better SDR brightness, so it overcomes more glare in a bright room.

LG B3 OLED
55" 65" 77"

The LG G4 OLED is a lot better than the LG B3 OLED. The G4 has HDMI 2.1 bandwidth on all four of its ports, it supports up to 4k @ 144Hz, so it's more versatile if you own multiple devices that need high bandwidth, and it's better for PC gamers with high-end graphics cards. The G4 gets a lot brighter overall, so highlights in HDR content really stand out on it, and it overcomes more glare in a bright room while watching SDR content. You also don't have to trade in brightness for performance on the G4 since it maintains its HDR brightness much better while in Game Mode.

The LG G4 OLED has a very sleek and modern design. It's essentially the same as last year's LG G3 OLED, with very thin bezels and a flat side profile, which means it's completely flush when wall-mounted.

Stand

Unlike the G3, a stand is included with the 55-inch and 65-inch models in North America, so you don't have to purchase a third-party stand if you don't plan on wall-mounting it. In some other regions, you can get the 55-inch and 65-inch models with either a stand or a wall mount.

The stand is small but is made from metal, and although there's a bit of wobble when the TV is pushed on, it recovers quickly and doesn't cause any issues. The stand can be adjusted to two different positions. The low position lifts the TV about 2.28", which brings the screen very close to your table. The high position lifts the TV about 3.94", so most soundbars fit underneath without blocking the screen.

Footprint of the 65-inch stand: 19.1" x 10.4".

Back
Wall Mount VESA 300x300

The back of the TV has a very clean and minimalistic look. It's made of textured metal with a metallic silver border at its edges. There are recessed cutouts in the back that can be used to funnel cables through, and those cables can be funneled through the intuitive stand for cable management. If you want to wall-mount the TV, you can still do so, but the 55-inch and 65-inch models don't come with LG's Slim Wall Mount.

The LG G4 TV has outstanding build quality. It's made of metal throughout, so the construction is solid, and the TV doesn't flex except for some very minor flex in the middle of the back panel. It does wobble a bit more than other LG OLEDs with a stand, but this doesn't cause any issues.

The TV has fantastic PQ EOTF tracking. Some shadows and mid-tones are slightly brighter than intended, but the TV tracks the curve very closely. With content mastered in 600 or 1000 nits, there's a sharp cutoff at the TV's peak brightness, but since the TV is bright enough to display content mastered at those levels, a roll-off isn't necessary. With content mastered at 4000 nits, there's a more gradual roll-off to preserve detail in very bright highlights.

WOLED

The LG G4 TV uses a WOLED panel with a WRGB pixel structure where all four pixels are never lit at the same time. Due to its subpixel layout, it has minor issues with displaying text on Windows since ClearType isn't well optimized to non-RGB subpixel layouts, but most users won't be bothered by this.

What really separates the TV from other WOLEDs is the use of Micro Lens Array (MLA) technology. MLA acts as a focusing layer in front of the WOLED panel, allowing it to get much brighter without the TV having to run hotter. MLA adds a slight haze to the screen, but the haze isn't noticeable at all when watching the TV. Note that the 97-inch model doesn't have MLA technology.

The TV has a nearly instantaneous response time, resulting in incredibly clear motion with almost no blur behind fast-moving objects. Due to the sample-and-hold nature of OLED technology, there's still some persistence blur when gaming at 60Hz, but it's not noticeable at higher refresh rates.

The LG G4 TV doesn't have a traditional backlight and doesn't use pulse-width modulation (PWM) to dim each pixel, but it's not completely flicker-free. There's a slight dip in brightness that corresponds to the TV's refresh rate. This is very different from the PWM flicker on TVs with LED backlights and occurs on every OLED we've tested. It's not noticeable, and most people won't be bothered by this, but it can still bother people who are extra sensitive to flicker.

The LG G4 TV has an optional motion interpolation feature to help improve the appearance of motion. It works well with slower scenes but struggles with fast-moving action, so there's noticeable haloing and artifacts present in busier scenes, especially if you use the settings too aggressively.

The TV removes judder when watching 24p movies or TV shows when the Real Cinema setting is enabled, even from sources that can only send a 60Hz signal, like a cable box. Unfortunately, movies and TV shows aren't judder-free when BFI is enabled because the BFI feature only flickers at 60Hz.

The LG G4 has exceptionally low input lag when set to Game Optimizer with 'Prevent Input Delay' set to 'Boost,' resulting in a very responsive gaming experience with very little delay between the actions on your controller and what happens on screen. For chroma 4:4:4 to work properly, the input label must be set to 'PC,' or the '4:4:4 Passthrough' setting must be enabled.

If you're a retro gamer, you can see the input lag results in 4:3 @ 60Hz below.

The LG G4 supports all common formats, and it displays chroma 4:4:4 properly, which is important for clear text from a PC.

There are two settings you can use to passthrough proper chroma 4:4:4. The first is to change the input label to 'PC,' and the second is to enable the '4:4:4 Passthrough' setting in the 'HDMI Settings' menu. Both of these options work the same and lock you out from using the 'Peak Brightness,' 'Noise Reduction,' 'MPEG Noise Reduction,' 'Smooth Gradation,' and 'Real Cinema' settings.

The TV runs the 2024 version of LG's proprietary smart interface, webOS. The interface is fast and easy to use, and it supports user profiles, so you can customize the home page for different users.

Unfortunately, the TV has a couple of bugs. Sometimes, the TV doesn't properly switch out of the Game Optimizer setting, so you're locked out of settings that should be available in other picture modes. To fix this, you can turn Game Optimizer on and disable ALLM and VRR. When you do this and switch to a different picture setting, everything works as it should.

The second bug causes the occasional black screen when changing resolutions and refresh rates frequently in a short period of time. The only fix for this is to unplug and re-plug the TV in, but this is unlikely to happen with real-world usage.
