LG OLED C5 vs Sony Bravia 8 MK2

LG C5 finally does what we have been waiting for years in the C series – it exceeds 1000 nits of brightness! This is a significant change compared to previous models in the series and also very important – because this is exactly the level of luminance around which most HDR content is now created on streaming platforms. The image finally has the right “glow,” and details in bright areas look as they should even without the use of dynamic metadata. However, there are scenes where the C5, like most OLED televisions, has some issues. Especially when the screen needs to illuminate fully. In our test sequences, such as the bright scene from the movie The Meg, brightness clearly decreases. Don’t get us wrong, this result isn’t bad; it’s more of a reminder that OLED technology still has its limitations. They are getting smaller year by year, but still.

Now, what about the colors? They are very good. Although the C5 does not match the OLEDs with QD-OLED or Tandem RGB panels, the DCI-P3 coverage at 97% and 73% BT.2020 will satisfy even the most demanding viewers. The colors are saturated, natural, and very consistent in HDR materials.

Thanks to the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating to nearly reference quality in films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is simply stunning – details in bright parts of the image remain perfectly visible, while night scenes captivate with depth and contrast. However, it's not perfect. Compared to the fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing peak luminance to 100% white brightness in HDR mode, the Bravia 8 II is even two or three times dimmer than the LG G5 or Samsung S95F models. This was particularly evident in a scene from the movie The Meg – the screen became noticeably darker than in competing televisions. Despite this drawback, the results of the Bravia 8 II still place it among the very top of the market. It deserves praise for its absolutely top-notch color gamut coverage – DCI-P3 at nearly 100%, and BT.2020 close to 90%. These parameters allow for fully extracting the potential of HDR content and providing a cinematic experience in the comfort of your home.

LG C5, like other TVs we tested, was checked in the best possible factory mode – which remains Filmmaker Mode. And here we have good news: in SDR materials, LG once again did a solid job. The white balance and color reproduction straight out of the box are at a very high level. Most errors – both in balance and in the color test (Colour Checker) – did not exceed a ΔE value of 3, which is the threshold above which differences become visible to the naked eye. Such factory settings are something we would like to see in many more TVs!

However, the situation is different for HDR content, which is really what the C series was created for. Here the C5 performs weaker. The excessive presence of blue in the white balance causes the image to appear noticeably cooled – which affects, for instance, unnaturally pale skin tones and somewhat shifted tonality of the entire scene. Fortunately, LG provides very precise calibration tools, and we – as always – took advantage of them.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the television can reproduce colors in a pleasing and natural way, although “good” here does not mean “best in class.” The white balance definitely needs adjustment – skin tones tend to lean into slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the EOTF curve characteristics show a tendency to brighten the darkest parts of the image. This is probably due to the manufacturer's desire to highlight as many details as possible, even in deep shadows. Is this a good approach? It's hard to say definitively, but we know one thing – it's not an ideal solution.

We must honestly admit – in the case of the LG C5, it took really very little to achieve an almost perfect picture. After calibration, we managed to achieve compliance with reference screens at a level that impresses even compared to much more expensive models. The picture after our adjustment looks exactly as filmmakers and series creators would want it – without color distortions, with natural depth and subtle texture. LG has done a great job this year regarding factory settings and calibration potential. Hats off!

After calibration, the excessive cooling of the image caused by the strong boost of blue color was eliminated. Reds became deeper, and skin tones took on a natural, healthy appearance. Actors who previously seemed "cold" now appear much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II tends to lighten the darkest parts of the image. It's hard to say whether this is a deliberate choice by the manufacturer or a result of the panel design and software. In practice, this means that scenes the creators wanted to leave in deep darkness can reveal more details than intended. Nevertheless, the viewing experience after calibration is clearly better – warm, natural colors and realistic skin tones make watching on the Bravia 8 II simply more pleasant to the eye.

LG C5 handles lower-quality materials really well. One of the main issues older WOLEDs faced was posterization – unwanted "steps" in color transitions. The C5 uses a system feature to smooth these transitions, which works surprisingly effectively. The banding effect is almost completely eliminated, and the image gains consistency. Compared to last year's model, we feel that this feature works slightly weaker – but the good news is that it does not compromise the structure of the image. Film grain, textures, and details remain on the screen – nothing is smoothed out forcefully.

The C5 also does a great job of enhancing the quality of older recordings. Thanks to the α9 Gen6 processor (8th gen), "scaling to 4K" performs really solidly. The image is clear, the details are sharp, and the only minor drawback might be slightly visible jaggedness on some edges. However, there is no issue with overscan here – the image is not artificially cropped or shifted, which is a significant plus and still isn’t a given.

Upscaling and digital image processing are a true showcase of the capabilities of Bravia 8 II. Sony has long been regarded as a master in this field, and here it only confirms its reputation. The proprietary XR processor can extract nearly maximum quality from lower resolution materials—whether it's television or an old DVD movie, the image looks sharper, with more details and better depth. Sure, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it's hard to find anything to complain about.

The soft gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding on colored and gray gradients, while simultaneously preserving film grain and fine image details. It is this balance between delicacy and effectiveness that keeps Sony TVs among the best on the market in this category.

The LG C5 is equipped with a 144 Hz panel, and this, combined with the practically zero response time of the OLED pixels, makes it one of the best screens for watching dynamic content. It doesn't matter whether it's sports, fast-paced games, or just action – the image is as sharp as a razor.

And what about movies in 24 frames? LG thought of that too. The built-in "TruMotion" smoother allows you to adjust the image to your own preferences. The "de-judder" slider increases the smoothness in movies, while "de-blur" gently reduces blurring – although to be fair, it is almost imperceptible here anyway.

Motion smoothness is practically a closed topic in the case of Bravia 8 II. The OLED with 120 Hz refresh rate naturally provides a very clean, clear image in dynamic scenes, so there is little to complain about. However, particular praise is due to one of the best motion smoothing systems on the market. They allow for precise adjustment of film smoothness according to one's preferences – from gentle smoothing to an almost "theatrical" effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

LG C5 is a television designed with gamers in mind – and there’s not a hint of exaggeration in that. It's hard to find anything to criticize here. We have 144 Hz refresh rate, full support for VRR, ALLM, and up to four HDMI 2.1 ports with full bandwidth of 48 Gb/s. For those who have an Xbox, PS5, Nintendo, and a gaming PC all in one room – there are no limits, everything can be connected without any hassle.

The HDR configuration for gaming is also problem-free. The television properly supports the HGiG mode, which allows for an image consistent with the creators' intentions. For those interested, there’s also Dolby Vision in Gaming mode, though we still recommend HGiG as the most predictable and “pure” version of HDR for games.

The Game Bar is also included, which serves as the “command center” for the gamer. Everything that’s most important, from VRR settings, to picture modes, to frame rate information – is at our fingertips. The interface is simple and readable. It may look like something out of a space simulator, but it serves its purpose and just works; exactly as it should.

C5 is truly a complete package for every gamer.

Sony really learned its lesson from previous years and in the Bravia 8 II prepared a package of features for gamers that is difficult to describe as anything other than "almost perfect." We have everything expected in equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a convenient Game Bar that allows you to quickly preview parameters and change settings without leaving the game. Additionally, it's worth noting how smoothly and flawlessly these features work – no delays, no strange stutters. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts." The manufacturer still gives us only two full-bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, it starts a game of cable swapping. It's also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those TVs that can comfortably be placed in the center of a gaming lounge, allowing you to enjoy gameplay without significant compromises.
