The LG C3 OLED is the mid-range model in LG's 2023 OLED lineup, sitting above the entry-level OLED 'B' series LG B3 OLED and below the 'Gallery Style' LG G3 OLED and the 8k LG Z3 OLED. OLED TVs like the LG OLED C3 are self-emissive; unlike LCD panels found on other TVs, there's no backlight. Instead, an OLED's pixels can change their brightness levels individually and independently of the other pixels, allowing them to display nearly-perfect contrast, with deep inky blacks and no distracting blooming or haloing around bright objects.

The 'C' series is usually LG's most popular OLED, as it typically has almost all of the features of the 'G' series but at a more manageable price point. Indeed, aside from the G3's Micro Lens Array (MLA) technology, the C3 comes with everything the G3 does, like the 2023 version of LG's proprietary webOS smart interface and four full HDMI 2.1 bandwidth ports. It also has LG's latest 2023 processor, the α9 AI Processor Gen6, which promises improved image processing through LG's Brightness Booster Max and AI Tech technologies, as well as the ability to up-mix 2-channel audio into virtual 7.1.2 channel sound using AI Sound.

Our Verdict

8.9 Mixed Usage

The LG C3 is an amazing TV, sure to please all but the most demanding buyers. The very good brightness in both SDR and HDR makes it well-suited to watching anything, from SDR content to the latest hit movies in HDR. It has superb reflection handling, and with its good peak brightness, the TV can handle bright rooms or glare without issue. But like almost every OLED on the market, it's better suited for a dark room, where its OLED panel, with its deep inky blacks, truly performs at its best. Its very low input lag makes it a gamer's dream, as your inputs are translated almost instantaneously to the screen, and its superb response time makes it a great choice for any fans of fast-moving content, be it sports or games, as action stays clear and crisp throughout. The TV also supports DTS, making it a fantastic choice for your home entertainment center.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Fantastic reflection handling.
  • Image remains accurate at a wide angle.
  • Very good peak brightness in HDR and SDR.
Cons
  • Aggressive ABL can get distracting with large areas of brightness.
8.6 TV Shows

The LG C3 is an excellent TV for watching TV shows. It has fantastic reflection handling, and combined with its very good peak brightness in SDR, it can handle bright rooms or rooms with lots of glare. Its viewing angle is superb, so the image remains consistent even when viewing the TV entirely from the side. If a group is sitting around the TV to watch the latest episode of their favorite show, they'll have a great viewing experience no matter where they're sitting. The TV also has very good sharpness processing, so lower-resolution content is upscaled well, and when combined with the panel's excellent low-quality content smoothing, your shows will still look great.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Fantastic reflection handling.
  • Image remains accurate at a wide angle.
  • Very good peak brightness in HDR and SDR.
  • Excellent low-quality content smoothing.
Cons
8.8 Sports

The LG C3 is an incredible TV for watching sports. It has exceptional reflection handling, which is great when watching shows in a room with glare, and the TV gets bright in SDR, so it handles bright rooms well. The TV's viewing angle is superb, so the image remains consistent even when viewing the TV from the side, so those sitting off-center will have a pleasant viewing experience. It has an incredible response time, so motion, like fast-moving players, is crisp and sharp, with no blurring. The TV has very good color uniformity, so when watching sports with large areas of uniform color, like hockey, you won't be distracted by annoying smudges or color variations in the image.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Fantastic reflection handling.
  • Image remains accurate at a wide angle.
  • Very good peak brightness in HDR and SDR.
  • Excellent low-quality content smoothing.
Cons
  • Aggressive ABL can get distracting with large areas of brightness.
9.4 Video Games

The LG C3 is a fantastic TV to spend your evenings immersed in your favorite games. Enabling Game Mode doesn't noticeably affect image quality, so your games simultaneously look great and feel super responsive due to the TVs incredibly low input lag; your inputs are translated to the on-screen action almost instantly. The TV has fantastic reflection handling, and combined with its very good peak brightness in SDR, this makes it a fantastic OLED for bright rooms or rooms with glare. The response time is exceptionally low, so no matter how fast the action moves, you won't have any blur or ghosting. As with many OLEDs, this is truly a standout TV for gamers.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Fantastic reflection handling.
  • Very low input lag.
  • Impressive gaming features.
  • HDMI 2.1 bandwidth on all four ports.
  • Very good peak brightness in HDR and SDR.
Cons
  • TV is a bit dimmer in Game Mode.
8.9 HDR Movies

The LG C3 is an excellent TV for watching the latest hit movies. Like all OLEDs, the C3 has incredible contrast, with deep inky blacks and no blooming around bright highlights. It has very good HDR peak brightness, so bright highlights look great next to the perfect blacks. It also has excellent low-quality content smoothing and very good low-resolution upscaling, so whether you like to watch movies on legacy formats like DVDs or through streaming services like Netflix, your content is free of macro-blocking, and details are preserved. The TV handles judder perfectly, so your movies are judder free. The TV isn't very color accurate, however; while most viewers won't notice this, if you're particular about color accuracy, this will annoy you, so spend the time calibrating it for the best viewing experience.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Automatically removes 24p judder from any source.
  • Wide color gamut for HDR content.
  • Supports DTS audio formats, which is great for DVDs and Blu-rays.
  • Very good peak brightness in HDR and SDR.
  • Excellent low-quality content smoothing.
Cons
  • Fast response time results in noticeable stutter.
  • Colors aren't as bright as pure white.
9.0 HDR Gaming

The LG C3 is an outstanding TV to be blown away by the latest hit games in HDR. Enabling Game Mode slightly reduces overall HDR brightness but won't negatively affect your gaming experience. The TV has remarkably low input lag with Game Mode on, so games feel super responsive; your inputs almost instantly translate to the on-screen action. The TV can handle all commonly used resolutions, like 1440p @ 120Hz and 4k @ 120Hz. It has fantastic reflection handling, and when combined with the TV's satisfactory HDR brightness in Game Mode, you'll enjoy gaming on the C3 even during the day. Still, it's certainly better suited to playing in a dark room. The response time is exceptionally low, so no matter how fast the action moves, you won't have any blur or ghosting.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Wide color gamut for HDR content.
  • Very low input lag.
  • Impressive gaming features.
  • HDMI 2.1 bandwidth on all four ports.
  • Very good peak brightness in HDR and SDR.
Cons
  • Colors aren't as bright as pure white.
  • TV is a bit dimmer in Game Mode.
9.4 PC Monitor

The LG C3 is a fantastic TV for PC gaming, but like all OLEDs, using it as a PC monitor has some caveats. It has a nearly-instantaneous response time and incredibly low input lag, so games, or your mouse cursor, are fluid and responsive, with almost no distracting motion blur behind fast-moving objects. Its viewing angle is amazing, so even if you sit in front of the TV, you won't notice any discoloration or dimming at the edges. It gets bright in SDR and has amazing reflection handling, so it'll look great even if your office setup is in a bright room or in front of some windows. Unfortunately, like many TVs, the C3 doesn't use a standard RGB subpixel layout, so text isn't very clear when used as a monitor, and its brightness in SDR is significantly reduced when the TV is set to PC mode, or with the 4:4:4 Passthrough option set to on. Finally, as with all OLEDs, there's a risk of permanent burn-in when exposed to static elements, like the UI elements of a computer desktop.

Pros
  • Near-infinite contrast ratio for perfect blacks.
  • Fantastic reflection handling.
  • Image remains accurate at a wide angle.
  • Very low input lag.
  • Impressive gaming features.
  • Very good peak brightness in HDR and SDR.
Cons
  • Aggressive ABL can get distracting with large areas of brightness.
  • TV is a bit dimmer in Game Mode.
  • 8.9 Mixed Usage

Compared To Other TVs

The LG C3 is an excellent OLED TV with exceptional picture quality but is only an incremental improvement over its predecessor, the LG C2 OLED. It doesn't have the LG G3 OLED's MLA focusing layer, which allows the G3 to get extremely bright, so in theory, there's a big difference between the C3 and G3 this year. However, in actual usage, the difference in brightness between the two TVs isn't very noticeable and isn't worth the price difference for most people. As the C3 is an incremental upgrade over the C2, get the cheapest one when shopping. When compared to OLEDs from other brands, the Sony A95K OLED, Samsung S95B OLED, and Samsung S95C OLED are all marginally better than the C3 when it comes to image quality, as QD-OLED panels are very colorful and can output very bright and saturated colors.

If you're still shopping for the best TV for your needs, check out our recommendations for the best OLED TVs, the best 4k TVs, and the best TVs for watching movies.

LG C2 OLED
42" 48" 55" 65" 77" 83"

The LG C3 OLED and LG C2 OLED are very similar TVs, with the C3 being a marginal improvement over its predecessor. The C3 is a bit brighter, but this isn't noticeable in practice. The C3 also has better low-resolution sharpness processing, making legacy content on DVDs or low-resolution online streaming look better than on the C2. The C3's biggest improvement over the C2 is its support of DTS audio formats; this makes it a much more interesting TV for home entertainment fans, as Blu-rays and DVDs tend to use DTS for their audio tracks. 

LG G3 OLED
55" 65" 77" 83"

The LG G3 OLED is better than the LG C3 OLED. They're both nearly identical, except that the G3 doesn't come with a stand, instead having a slim wall mount included in the box and a fully flat profile that allows the TV to be completely flat on the wall when wall mounted. In theory, the G3 can also get much brighter than the C3; however, in practice, you won't see much difference except in certain contexts, such as when bright white clouds are displayed. They both offer DTS audio support this year, a clear improvement over both preceding models.

Samsung S90C OLED
55" 65" 77" 83"

The LG C3 OLED and Samsung S90C OLED are similar TVs occupying the same market position. Of the two, the Samsung is the better gaming TV and slightly better overall TV, while the LG is the better TV for movie fans. The Samsung gets brighter than the LG, especially in HDR; not only that, but it also maintains its HDR brightness better in Game Mode. It also supports 4k @ 144Hz, while the LG is limited to 4k @ 120Hz. It has a much wider color gamut and more accurate colors. However, the LG supports DTS audio formats and Dolby Vision, making it great for Blu-ray fans. It also has better low-quality content smoothing than the Samsung TV, making it better for watching streaming content, especially in low-bitrate situations.

LG G2 OLED
55" 65" 77" 83" 97"

The LG G2 OLED and LG C3 OLED are comparable TVs, each with their particularities. The G2 doesn't come with a stand, but a slim wall mount is included in the box. It also has a fully flat profile that lets the TV completely flush with the wall when wall-mounted. The G2 can also get a bit brighter than the C3; however, you won't see much difference in actual usage. The C3 supports DTS audio formats while the G2 doesn't, so the newer model is a better fit for a home entertainment setup. 

Sony A80L/A80CL OLED
55" 65" 77" 83"

The LG C3 OLED is better than the Sony A80L OLED for all but the most hardcore home entertainment enthusiasts. They both use WOLED panels, but the LG is brighter in both HDR and SDR and maintains its brightness better in Game Mode. The LG also has FreeSync support and slightly lower input lag than the Sony, so it's better for gamers. They both support advanced audio and video formats like DTS and Dolby Vision. The only edge the Sony has is its processing capabilities; typical of Sony, it's class-leading when upscaling low-resolution or smoothing low-quality content, and it's an accurate TV calibrated well out of the box. While the LG isn't quite up to the level of the Sony in terms of image processing, it's certainly no slouch in that department, making it the better TV for most people.

Samsung S95C OLED
55" 65" 77"

The Samsung S95C OLED is better than the LG C3 OLED. The Samsung is brighter than the LG and can hold onto its brightness much better than the LG in Game Mode. The Samsung has a much wider color gamut than the LG; it can output bright, vibrant colors, making the TV pop. It also has much better HDR gradient handling than the LG, so you won't notice annoying banding in scenes with color gradients. The LG does have better low-resolution upscaling, so it will do a better job with low-resolution content or streaming content at low bitrates. The LG also supports every audio format, including DTS, so it's the better overall TV for a home entertainment setup.

Samsung S95B OLED
55" 65"

The Samsung S95B OLED is better than the LG C3 OLED. The Samsung TV is brighter than the LG in most usage. However, it can hold onto its brightness much better than the LG in Game Mode. The Samsung has a much wider color gamut than the LG; it can output vibrant, saturated colors, making the TV really pop. It also has much better HDR gradient handling than the LG, so you won't notice annoying banding in scenes with color gradients. The LG does have better low-resolution upscaling, so it will do a better job with low-resolution content or streaming content at low bitrates. The LG also supports every audio format, including DTS, so it's the better overall TV for a home entertainment setup.

Sony A95K OLED
55" 65"

The Sony A95K OLED and LG C3 OLED are comparable TVs, each with its strengths, with the Sony being marginally better overall. The Sony is a bit brighter than the LG in HDR; however, the LG is brighter in SDR. The Sony has a much wider color gamut than the LG; its QD-OLED panel outputs vibrant, saturated colors, which makes the TV pop. It also has much better HDR gradient handling than the LG, so you won't notice annoying banding in scenes with color gradients. While both TVs have good image processing, the Sony has the edge in upscaling, so low-resolution content will look sharp and clear on the Sony. While both TVs are gaming beasts, the Sony TV's input lag is a bit higher than the LG's, so the LG is better if you play competitive games at high skill levels.

Hisense U8K
55" 65" 75" 85" 100"

The Hisense U8K and LG C3 OLED are different TVs, each with their own strengths, although the LG is better overall. The Hisense gets much brighter than the LG and is a bit more colorful, so it's much better suited for bright rooms. The LG, however, has a nearly infinite contrast ratio due to its OLED panel, leading to much better dark room performance. The LG also has better image processing overall, a vastly wider viewing angle, and a near-instantaneous response time with no quirky VRR performance.

Stand

The stand on the 65-inch LG C3 is identical to the stand found on the 65-inch LG C2 OLED, and it has the same issues: it's a bit small, and the TV wobbles on it. However, it doesn't take the TV long to settle after it starts wobbling, so it isn't an issue in practice. The stand lifts the bottom of the screen 2.7" above the table, so most soundbars will fit without blocking the screen. The 83-inch uses a bigger stand, the same as on the 83 and 48-inch LG C2 OLED or the LG C1 OLED. The 42-inch model of the C3 uses two feet on each side of the screen instead of a central stand.

The back of the TV feels quite nice; it's made of a textured, brushed metal. It almost feels like fabric to the touch. A large plastic panel is on the back, with the inputs on its right-hand side. The TV comes with cable management clips through which you can funnel cables towards a small plastic cover, and exiting through a another clip on the back of the stand. Check out the full cable management photo here, but take note that you can route cables through the small plastic cover.

The LG C3 is incredibly well-built. It feels premium, the fabric-like texture on the back feels unique and nice to the touch, and the TV itself doesn't flex much. The stand is small and doesn't take much space, but unfortunately, the TV wobbles quite a bit on it; again, it does settle in quickly, and it's not a problem in practice. Overall, very solidly built.

The LG C3 has a nearly infinite contrast ratio like every other OLED. As each pixel can individually control its own brightness due to OLED's self-emissive technology, you can have super bright highlights next to pixels that are completely off, leading to perfect blacks with no blooming or haloing. It's very impressive in a dark room.

0.101

The LG C3 has very good HDR peak brightness. In certain scenes, it's a noticeable improvement from last year's LG C2 OLED. Like other OLEDs, large bright scenes are significantly dimmer than smaller highlights due to the Automatic Brightness Limiter (ABL). It's not very noticeable during normal viewing, as the brightness transitions are typically smooth and seamless. However, the TV is much dimmer when watching very bright HDR content for extended periods, and the ABL is distracting when using the TV as a PC monitor.

Setting Peak Brightness to 'Off' reduces the ABL feature's aggressiveness but also reduces the panel's peak brightness in all scenes, which makes the TV look dimmer all the time.

These measurements are after calibrating the HDR white point with the following settings:

  • HDR Picture Mode: Cinema (User Settings)

The LG C3 has fantastic PQ EOTF tracking. As it's an OLED, it has perfect blacks and follows the PQ EOTF curve very well. The TV is over-brightened at lower luminance levels. When the TV gets near its peak brightness, its tracking acts differently based on the content it's displaying; for content mastered at 600 and 1000 nits, which is the majority of content, the TV clips everything above its max brightness, resulting in a loss of fine detail in very bright scenes. For content mastered at 4000 nits, the TV does tone mapping; however, its roll-off is pretty quick, so it won't preserve as many fine details here as the LG C2 did.

Note that this particular PQ EOTF tracking curve was done with the new Expression Enhancer setting set to 'Detail', as with the setting set to 'Off', the TV was over-brightening most of the EOTF. You can see how the different Expression Enhancer settings impact the EOTF curve here

The LG C3 OLED has very good peak brightness in SDR. It's a bit brighter than the LG C2 OLED, especially noticeable when bright elements take up most or all of the screen. Its Automatic Brightness Limiter (ABL) is a bit less aggressive than on the C2, but it still dims large bright scenes significantly compared to smaller highlights.

Setting Peak Brightness to 'Off', which bypasses the ABL, reduces the peak brightness to about 200 cd/m², which is a much more radical reduction than what we saw on the LG C2. Note that setting the input to Game Mode or PC Mode, or setting the 4:4:4 Pass Through option to 'On' also locks the Peak Brightness option to 'Off'.

These measurements are after calibration with the following settings:

  • Picture Mode: Expert (Dark Space, Night)
  • OLED Pixel Light:: 100
  • Peak Brightness: High
  • Color Temp: Warm 50

The TV has an amazing color gamut. Like most TVs in this market range, the LG C3 has nearly perfect coverage of the DCI-P3 color space, which most current HDR content uses. However, when displaying very bright images, its color accuracy is off; it struggles with displaying accurate greens, and all colors are generally undersaturated. Its tone mapping is also off, like on the LG C2 OLED, struggling with accurately tone mapping desaturated colors. Note that these results are done with the TV receiving a near 1000 nits stimulus signal; in actual usage the TV's color accuracy and tone mapping is much better, as our results here amount to a stress test.

The TV also has good coverage of the Rec. 2020 color space used by some content. Still, it can't display the full range of green or cyan; colors are again generally undersaturated, and its tone mapping still struggles with desaturated colors. Overall it isn't the best TV for viewers who are really into HDR color accuracy, but otherwise, it looks great. If you're looking for a more color-accurate OLED, take a look at the Samsung S90C OLED.

The LG C3 has very good pre-calibration accuracy in SDR. Its gamma is below the 2.2 target, so it's on the brighter side by default, but its color temperature is quite good. However, its color accuracy is only average; its saturated reds, greens, magentas, and yellows have accuracy errors, enough that the colors don't look quite right on some content.

After calibrating to a D65 white point, the LG C3 has fantastic accuracy. The grayscale was easy to configure, and the TV now eliminates almost all white balance issues. The colors, however, are harder to calibrate, and they still show much of the same accuracy issues that they had pre-calibration; still, they're now good enough for everyone but professionals.

The LG C3 has excellent gray uniformity, but much like the LG C2 OLED and the LG G3 OLED, there are faint vertical lines in very dark scenes and faint pinkish vertical bands on the screen when uniform colors are shown. It's a common issue with the panel technology used in LG's OLEDs, but they're subtle, and you won't notice them in practice. There are no signs of the grid pattern that affected some 2021 units and no signs of the "Venetian blind effect" either.

The LG C3 uses the same panel as last year's LG C2 OLED, namely the 2022 WBE panels dubbed 'Ex'. The manufacturer advertises these panels to be brighter, have better heat dissipation, and be less prone to burn-in than those found on the 2021 LG C1 OLED. Like all LG OLED TVs, all four subpixels are never lit simultaneously. Also, note that this TV uses an RWBG subpixel layout, so it has issues with text display on Windows, as ClearType isn't well-adjusted to non-RGB subpixel layouts.

Like all OLEDs, this TV has an incredibly fast pixel response time. There's very little blur behind fast-moving objects, but due to the sample-and-hold nature of OLED technology, there's still some noticeable persistence blur. There's some overshoot in nearly-black scenes, but it only happens when coming out of a fully-off state and then quickly settles, so you won't notice it.

Like all of LG's high-end OLEDs, the optional motion interpolation feature works well. However, it also introduces what is commonly known as the 'soap opera effect', which will annoy some people. Motion appears significantly smoother, with less persistence blur, thanks to the higher frame rate, but again, there are some noticeable artifacts in busy scenes.

It works well across a wide refresh rate range, even when it drops very low, as the TV supports Low Framerate Compensation (LFC). There's some flickering when VRR is enabled, much as was reported on the LG C2 OLED in 2022, and it's noticeable in low and fluctuating frame rate situations on a near-black screen. See a video of this flickering in action here.

The TV has low input lag, resulting in a very responsive gaming experience. Although it's still not as good as high-end gaming monitors, it's better than most TVs and good enough for most gamers. These results are with the Boost Mode setting set to 'on' in the 'Game Optimizer' menu, which reduces input lag by 2-3 ms. Like most TVs, the input lag is too high outside of 'Game Mode' for competitive reaction-based games, although it's much better on the LG C3 than on the LG G3 OLED or the LG C2 OLED. The input lag is higher when forcing a 4:3 aspect ratio versus setting it to 'original'. Here are some measurements, all done at 120Hz:

    When set to 'Original' aspect ratio:
  • 1920x1440: 10.1 ms
  • 640x480: 27.3 ms
  • 320x240: 28 ms
    When set to '4:3' aspect ratio:
  • 1920x1440: 26.8 ms
  • 640x480: 27.4 ms
  • 320x240: 28 ms

Note that to get the lowest input lag with Chroma 4:4:4 support, you need to set the input to PC with Game Mode enabled. Like on the G3, the C3 can enable 4:4:4 Pass Through in the 'Game Optimizer' settings, resulting in Chroma 4:4:4 support with the lowest input lag. Enabling 4:4:4 Pass Through disables motion interpolation settings and a few picture processing settings and is identical to setting the input to PC.

Enabling BOOST in the 'Game Optimizer' settings, or setting the input to PC Mode, does not noticeably affect gamma when compared to having BOOST disabled. Similarly, gamma is not noticeably affected when comparing PC Mode to HDMI input or the 4:4:4 Pass Through option enabled. You can check out a few examples here:
