LG G6 OLED  TV Review

The LG G6 OLED has excellent HDR brightness overall. Small specular highlights are incredibly bright, so highlights really pop in most scenes. Like any OLED, brightness decreases as the size of bright areas increases due to the TV's automatic brightness limiter (ABL), but the TV's ABL is less aggressive than most other OLEDs on the market, so entirely bright scenes still look punchy. 

Unfortunately, there's a caveat. The TV doesn't achieve the same level of brightness in real scenes as it does with test slides, so it actually looks dimmer than 2025's LG G5 OLED with most content. This is unusual, and even the LG C6 OLED is a bit brighter in most real scenes. 

The posted results are with the TV in its most accurate picture mode with 'Dynamic Tone Mapping' and 'Expression Enhancer' disabled. Below are the results with DTM turned on, which significantly increases brightness in most real scenes but isn't as accurate.

• Hallway Lights: 2,156 cd/m²
• Yellow Skyscraper: 1,596 cd/m²
• Landscape Pool: 542 cd/m²

If you're trying to squeeze the most brightness out of the TV as possible, below are the results in the ‘Vivid’ picture mode with out-of-the-box settings, which is the brightest setting available, but is also very inaccurate.

• Peak 2%: 4526 cd/m²
• Peak 3%: 4783 cd/m² (Highest peak measured)
• Peak 10%: 2526 cd/m²
• Peak 25%: 1257 cd/m²
• Peak 50%: 687 cd/m²
• Peak 100%: 401 cd/m²

The TV is slightly brighter when you switch to the 'Game Optimizer' mode.

The posted results are with the TV in 'Game Optimizer' mode with 'Dynamic Tone Mapping' and 'Expression Enhancer' disabled. Below are the results with DTM turned on, which significantly increases brightness at the cost of accuracy.

• Hallway Lights: 2,085 cd/m²
• Yellow Skyscraper: 1,958 cd/m²
• Landscape Pool: 1,140 cd/m²

The LG G6 OLED has outstanding peak brightness in SDR, and the TV is bright enough to overcome glare in almost any well-lit room. Like all OLEDs, the TV's automatic brightness limiter (ABL) means large areas of brightness aren't as bright as smaller areas, like when watching sports. However, it's still bright enough with all SDR content that it doesn't look dim. 

The LG G6 OLED TV has a nearly infinite contrast ratio, giving it perfect contrast. Due to OLED's self-lit pixels, it displays bright highlights next to perfect inky blacks, making it very impressive in a dark room.

Since OLEDs don't use lighting zones and instead have individual pixels that can be lit up to their maximum brightness next to pixels that are turned off, there's no haloing when bright elements are surrounded by deep blacks.

This TV is an OLED without a backlight, so its self-lit pixels give it the same performance as a TV with perfect local dimming and no zone transitions. We still film the zone transition video so you can see how it compares to an option with local dimming.

There's no difference in dark scene behavior when the TV is set in Game Optimizer.

Because OLEDs can turn off individual pixels, the TV has perfect black uniformity with no haloing around bright objects.

The TV has fantastic SDR color volume. It covers the entirety of the DCI-P3 color space and has very good coverage of the widest BT.2020 color space. Colors are vibrant and punchy on this TV regardless of the SDR content you're watching. 

The LG G6 has amazing HDR color volume. It displays both dark and bright colors very well, which leads to rich and vivid colors in HDR content. Unlike QD-OLEDs like the Samsung S95F OLED, it has a white subpixel that's used to increase brightness, which slightly washes out colors in very bright scenes. 

Although the TV has higher individual color luminance than the LG G5 OLED, it actually covers a bit less of the DCI-P3 and BT.2020 color spaces in HDR. In practice, the difference is hardly noticeable, but it's worth noting. 

The LG G6 has very good SDR accuracy before calibration, but it's not perfect. The color temperature is close to 6,500K and colors have great accuracy overall. However, the white balance and gamma are wavy, and dark areas are too dark, while bright areas are too bright. 

This LG G6 TV has fantastic SDR accuracy after calibration. It's not too hard to calibrate, but you have to be a little more aggressive when making adjustments compared to previous LG OLEDs. Still, the white balance, gamma, and color temperature are nearly perfect. The overall accuracy of colors is excellent, with only minor inaccuracies that aren't visible in real content. 

See our full calibration settings. 

The LG G6 has great HDR color accuracy before calibration. The TV's color temperature is almost perfect, and the overall white balance is outstanding. However, most colors are a bit undersaturated and off target. 

This test was originally performed with firmware 43.02.66, which had worse white balance but much better color accuracy overall. Unfortunately, updating to firmware 43.02.67 negatively affected HDR accuracy by a pretty large margin. 

Unfortunately, calibrating the TV doesn't do much to improve HDR color accuracy. The sliders for each color channel barely affect the image, so it's impossible to fully calibrate the TV. It also doesn't clamp to the proper color space, which causes colors to look undersaturated. The best way to improve accuracy is to choose the 'Native' color space option and drop the 'Color' slider down to '49'.

After making these tweaks, the white balance is improved and colors are slightly more accurate, but the color temperature is slightly cooler than before calibration. 

The LG G6 has fantastic PQ EOTF tracking. When the TV was first released, HDR content was brighter than intended with firmware 43.02.60, as originally reported by outlets such as HDTV Test. We rechecked its tracking with firmware 43.02.66, and HDR content was still too bright. 

Fortunately, LG mostly fixed the over-tracking with firmware 43.02.67, but it's still not perfect. Some midtones are just slightly too dim or slightly too bright, but it's barely noticeable with real content. Highlights in content mastered at 600 nits are essentially perfect, but highlights are displayed dimmer than intended in 1000 nit and 4000 nit content before the TV rolls off at its peak brightness to retain detail in specular highlights. 

The LG G6 TV does a fantastic job smoothing out low-quality content. Macro blocking and pixelization are significantly reduced, and there's very little loss of fine details in the scene.

The TV does a fantastic job upscaling DVDs, standard definition streams, and other low-resolution content. Oddly, the 'Super Resolution' feature doesn't seem to do anything.

The LG G6 OLED has superb gradient handling with HDR10 content. The new 13-bit processing pipelining provides incredibly smooth gradients, with almost no visible banding at all. Unlike the LG C5 OLED and the LG G5 OLED, there are no diagonal dithering lines in HDR10, but there's still some moving dithering noise that's only noticeable if you sit very close to the screen. 

Unfortunately, the TV's gradient handling is much worse in Dolby Vision, and there's strange contouring that appears in certain scenes. This can be seen in the photos below or by watching this comparison video.

• Green Knight - HDR10 vs Dolby Vision 1
• Green Knight - HDR10 vs Dolby Vision 2
• Green Knight - HDR10 vs Dolby Vision 3
• Gradient - Dolby Vision | HDR10
• Gradient - Dolby Vision | HDR10
• Gradient - Dolby Vision | HDR10
• Gradient - Dolby Vision | HDR10
• Gradient - Dolby Vision | HDR10

On top of that, there are diagonal lines that are only visible in Dolby Vision. These lines don't show up in as many scenes as they do on the LG C5 OLED and the LG G5 OLED, but unlike those 2025 models, they're more spaced out and are visible from a normal viewing distance. Check out this video to see the lines for yourself.  

These issues with Dolby Vision are disappointing, especially for those who plan to use the internal apps, since there's no way to disable Dolby Vision on this TV. If you have an external streaming device like the Apple TV, your best option is to disable Dolby Vision and watch content in HDR10 instead. 

This TV has incredibly low input lag, ensuring a very smooth and responsive gaming experience.

Below are some additional input lag measurements.

4:3 @ 60Hz:

• 640x480: 25.8 ms
• 800x600: 32.5 ms
• 1024x768: 25.3 ms

If you don't want to use the 'Game Optimizer' Picture Mode, you can instead simply toggle the 'Game Optimizer' setting while staying in 'Filmmaker Mode'. However, unlike the LG G5 OLED, input lag is higher than it is if you solely use the 'Game Optimizer' picture mode when using this method. 

Filmmaker Mode with Game Optimizer Enabled:

• 60Hz: 21.8 ms
• 120Hz: 13.5 ms
• 165Hz: 4.4 ms

The TV supports all common resolutions up to 4k @ 165Hz, and it supports chroma 4:4:4, which helps with text clarity from a PC.

The TV supports FreeSync and HDMI Forum VRR and is certified as G-SYNC compatible, ensuring a nearly tear-free gaming experience from any VRR-enabled source. It works well across the TV's entire refresh rate range and supports sources with Low Framerate Compensation (LFC), which ensures your games remain nearly tear-free even when your frame rate drops very low.

The TV's CAD at its maximum refresh rate of 165Hz is fantastic. Pixels transition to their target RGB level almost instantly, so fast motion is very sharp. There's some minor overshoot in shadow details, but it's very hard to notice when gaming.

The TV's CAD at 120Hz is outstanding. It displays fast-moving objects without noticeable blur, so fast motion is clear. There's some subtle overshoot in near black scenes, though.

The TV's CAD at 60Hz is fantastic. Most transitions from one RGB level to another are nearly instantaneous, with no overshoot. 

The LG G6 is fully compatible with everything the PS5 offers, like 1440p @ 120Hz and 4k @ 120Hz, as well as HDMI Forum VRR. It also supports Auto Low Latency Mode, so you don't have to worry about switching to Game Optimizer to get the lowest input lag.

Unfortunately, the console's HDR calibration menu doesn't work as it should when you have HGiG enabled, since the calibration pattern only disappears when you have the sliders maxed out. However, if you move the brightness up 22 clicks on the calibration screen, the pattern stops changing. 22 clicks is roughly 2700 nits, which matches the peak brightness of the TV in the Game Optimizer picture mode. If you use this method to calibrate HDR, HGiG works as it should. 

This TV is fully compatible with everything the Xbox Series X|S offers, including 1440p @ 120Hz, 4k @ 120Hz, HDMI Forum VRR, FreeSync Premium Pro, and Dolby Vision gaming. It also supports Auto Low Latency Mode, so you don't have to worry about manually switching to Game Optimizer to get the lowest input lag.

Unfortunately, there's noticeable stutter in slow panning shots due to the TV's nearly instantaneous response time.

Adding motion interpolation to increase the frame rate of 24p content to 30 fps does a decent job at reducing stutter. There's still noticeable stutter, but the feature is very consistent, ensuring a smooth frame pacing.

This TV removes 24p and 25p judder from native apps and external devices that send a 24Hz or 25Hz signal, like an Apple TV with the 'Match Frame Rate' feature enabled. The TV also properly removes judder from 24p content that's being sent to it in either 60p or 60i. However, it doesn't remove 25p judder from 60p signals, and frames are held for an inconsistent duration, which causes motion to look jittery.

To remove judder on this TV, the Real Cinema setting must be enabled. Unfortunately, this setting is locked when OLED Motion Pro (BFI) is enabled. Enabling Quick Media Switching (QMS) causes judder on this TV when watching 24p content via a 60p signal. If you're watching content from a device that outputs a 60Hz signal, your best option is to turn off QMS. 

There's no micro judder with most sources. It drops occasional frames when watching 24p content sent via a 60p signal, unless you enable Quick Media Switching, but doing so causes normal judder. To completely avoid micro-judder with all streaming content, you're best off using the internal apps or a streaming device that matches the output signal to the frame rate of the content, like an Apple TV. 

The LG G6 has a nearly instantaneous response time, resulting in incredibly clear motion with almost no blur behind fast-moving objects when watching content. Due to the sample-and-hold nature of OLED technology, there's still some persistence blur at 60Hz, but it's not very noticeable when watching movies or shows.

There are no noticeable transition artifacts like intermediate colors or soft edges on this TV.

This 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.

This TV has an optional black frame insertion (BFI) feature that reduces the appearance of persistence blur at 60Hz. Unfortunately, it can only insert black frames at a 60Hz refresh rate, and there's still some blur present.

The LG G6 TV does an excellent job of reducing the intensity of direct reflections. Reflections from direct sources of light, such as a lamp or window placed opposite the screen, are dimmed considerably. You can still notice subtle reflections in dark scenes, but direct reflections aren't an issue at all during brighter scenes. 

Ambient light has barely any impact on black levels.

The TV does an excellent job with total reflected light. Direct reflections cause some minor diffraction artifacts, but the TV's glossy coating is very effective in minimizing the intensity of both indirect and direct reflections. There's some light diffusion, and reflections are softer than they are on other TVs with glossy coatings, like the LG G5 OLED.

This TV has great color saturation in a bright room. Ambient light barely has an impact on perceived color volume.

The LG G6 TV has an excellent viewing angle. There's color shift as you move to the sides of the screen, but outside of that, image quality barely degrades when you're watching from the sides of the screen. This makes it a great option for wide seating arrangements. 

Unfortunately, the G6 we bought and tested has a noticeable green tint when viewing the TV from an angle. It's a widespread issue that impacts almost all LG OLED panels but varies widely from unit to unit.

The TV has very good gray uniformity overall, but there are some imperfections worth noting. There's very little dirty screen effect in the center, which is great. However, scenes with near blacks (5% gray) have an unusual swirly pattern across the screen. Our unit also has some dead pixels and a line of pixels near the dead ones that is noticeably brighter than the rest of the image. This high exposure shot shows these imperfections. 

The LG G6 OLED uses an RGB tandem panel 2.0, which is a newer version of the panel found in 2025's LG G5 OLED. This panel has much better color separation than standard WOLED panels, but it still relies on a white subpixel.

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 LG has restructured the subpixels so it looks a bit better than previous generations.

You can see an additional subpixel photo showing other subpixels, as all four are never lit at the same time.

The LG G6 supports the full 48Gbps bandwidth of HDMI 2.1 on all four HDMI ports. This allows you to take full advantage of multiple high-bandwidth devices, such as if you own both current-gen consoles and a high-end gaming PC.

This TV passes through all Dolby Digital options. However, it doesn't support any DTS audio formats commonly used on physical media.

This TV supports HDR10 and Dolby Vision, but not the newer Dolby Vision 2. It's unclear if LG has any plans to eventually add support for the newer format or not. Unfortunately, there are issues with Dolby Vision that make it look worse than HDR10. 

The LG G6 OLED looks nearly identical to the LG G5 OLED. It has a sleek and modern design that looks premium. We purchased the version of the TV that comes with a stand, but it's also available with LG's Slim Wall Mount instead in certain regions. 

The stand does a good job of supporting the TV. It can be adjusted into two different height positions depending on your preference. The lower position only lifts the TV about 2.2 inches, making it hard to fit a soundbar underneath without blocking the screen. However, the higher position lifts the TV about 3.98 inches, which is high enough for pretty much any soundbar to fit underneath. 

Footprint of the 65-inch stand: 19.1" x 10.35".

The back of the TV has a minimalistic design that looks very clean. The inputs are on the left side in a shallow cutout, making them quite hard to access if you have it mounted flush to the wall. There are channels on the back you can use to run cables, and you can use the TV's stand to further help with cable management.

The LG G6 OLED is built with premium materials and has fantastic build quality, but there are some notable issues with our unit. It has a row of dead pixels, a stuck red subpixel, and a vertical line that makes some content look brighter on the right side than the left. 

The LG G6 OLED TV ships at launch with the 2026 version of LG's proprietary smart interface, webOS. LG promises at least five years of webOS updates on their TVs, and you get updated versions of the operating system once a year.

There are two settings in the 'Home Settings' menu, namely the 'Home Promotion' and 'Content Recommendation' settings. These settings remove the top banner ads and suggested content from the home screen. This gives your home screen a clean look, but there's no way to remove ads from the apps page.

• Remote (with 2x AAA batteries)
• User manuals
• Cable management brackets
• IR repeater

This TV shipped with firmware version 43.02.66, but 43.02.67 was released while we were testing it. All results have been rechecked with the new firmware.

The LG G6 OLED has a decent frequency response. The speakers get loud, and the sound profile remains well-balanced at high volumes, so dialogue is pretty clear at all levels. Unfortunately, the speakers don't output very much low-bass, making it sound a bit hollow.
