LG OLED C5 vs Sony Bravia 8 MK2

LG C5 has finally done what we've 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 very important – because most HDR content on streaming platforms is created around such luminance today. The image finally has the right "glow," and details in the highlights look as they should even without the use of dynamic metadata. However, there are scenes where the C5, like most OLED TVs, has certain issues. Especially when the screen has to light up entirely. In our test sequences, like the bright scene from the movie The Meg, brightness noticeably drops. Don't get us wrong, this result is not bad; it’s more of a reminder that OLED technology still has its limitations. Year by year, they are getting smaller, but they still exist.

Now, what about the colours? They are very good. Although the C5 doesn't match OLEDs with QD-OLED or Tandem RGB panels, its coverage of the DCI-P3 gamut at 97% and 73% of BT.2020 will satisfy even the more demanding viewers. The colours 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 near-reference quality in films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is absolutely stunning – details in bright parts of the image remain perfectly visible, and night scenes captivate with depth and contrast. However, it’s not perfect. Compared to its most formidable competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing peak luminance with 100% white brightness in HDR mode, the Bravia 8 II can appear two or three times dimmer than LG G5 or Samsung S95F models. This was particularly evident in a scene from the film The Meg – the screen became noticeably darker than in competitors' televisions. Despite this flaw, the Bravia 8 II's results still place it at the forefront of the market. It deserves praise for its absolutely top-notch colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow full potential extraction from HDR content and provide 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 the Filmmaker Mode. And here we have good news: in SDR materials, LG has once again done a solid job. The white balance and colour reproduction right out of the box are at a very high level. Most errors – both in balance and in the Colour Checker test – 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 what we'd like to see in many more TVs!

However, the situation is different for HDR content, which is what the C series was truly designed for. Here, the C5 performs weaker. An excessive amount of blue in the white balance causes the image to appear distinctly cooler – which affects things like unnaturally pale skin tones or somewhat shifted tonality of the entire scene. Fortunately, LG provides very precise calibration tools, and we – as always – made use of them.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the TV manages to render colours in a pleasant and natural way, although "well" doesn’t mean "best in class" here. The white balance definitely requires adjustment – skin tones tend to lean towards slightly pink/cool tones, both in SDR and HDR content. We also noticed that the EOTF curve characteristics show a tendency to brighten the darkest parts of the image. This is likely 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 very little to achieve an almost perfect image. After carrying out calibration, we managed to achieve compliance with reference screens at a level that impresses even compared to significantly more expensive models. The image after our adjustments looks exactly as filmmakers and series creators would want – with no colour distortion, natural depth, and subtle plasticity. 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 an overly strong boost in blue colour was primarily eliminated. The reds became deeper, and the skin tones took on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing hasn't changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest parts of the image. It's hard to say whether this is a deliberate effect by the manufacturer or a consequence of the panel's design and software. In practice, this means that scenes that the creators wanted to leave in deep darkness can reveal more details than intended. Despite this, the reception of the image after calibration is clearly better – the warm, natural tones and realistic skin shades make viewing on the Bravia 8 II simply more pleasant to the eye.

LG C5 handles lower quality materials exceptionally well. One of the main issues that older WOLEDs faced was posterisation – unwanted “steps” in colour transitions. The C5 utilises a system function that smooths these transitions, and it works surprisingly effectively. The banding effect is nearly completely eliminated, and the image gains consistency. Compared to last year's model, we feel that this function operates slightly weaker – but the good news is that it doesn't compromise the image structure. Film grain, textures, and details remain on the screen – nothing is forcefully smoothed out.

The C5 also excels at enhancing the quality of older recordings. Thanks to the α9 Gen6 (8th gen) processor, "scaling to 4K" is impressively solid. The image is clear, details are sharp, and the only minor drawback might be a slightly noticeable aliasing on some edges. However, there is no problem with overscan here – the image is not artificially cropped or shifted, which is a significant plus and still not a given.

Upscaling and digital image processing are a true showcase of the capabilities of the 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 the maximum from lower resolution materials – whether it's TV or an old movie from a DVD, the image appears clearer, with more detail and better depth. Sure, if we feed it exceptionally poor-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it’s hard to find fault.

The gentle gradation feature also performs excellently. In the “Medium” setting, it effectively smooths tonal transitions, eliminating stripes on colourful and grey gradients, while not destroying film grain or fine image details. It’s 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 display, and this, combined with virtually 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 razor sharp.

And what about movies at 24 frames? LG has thought of that too. The built-in "TruMotion" smoother allows you to adjust the picture to your own preferences. The “de-judder” slider increases fluidity in films, while “de-blur” subtly reduces motion blur – although to be honest, it’s practically invisible here.

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

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

Configuring HDR for gaming is also straightforward. The TV correctly supports the HGiG mode, which allows you to achieve an image that aligns with the creators' intentions. For those interested, there is also Dolby Vision in the Gaming version, although we still recommend HGiG as the most predictable and "clean" variant of HDR in games.

It also includes the Game Bar, which is a "command centre" for the gamer. Everything important, from VRR settings, picture modes, to frame rate information – is at our fingertips. The interface is simple and clear. 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 any gamer.

Sony has really done its homework from previous years and in the Bravia 8 II, it has prepared a package of features for gamers that is hard to describe as anything other than "almost perfect". We have everything you’d expect from equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that allows you to quickly check parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutter. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still provides us with only two full bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, the fun begins with plugging and unplugging cables. It's also surprising that there's no support for 1440p at 120 Hz – particularly important for Xbox gamers. Overall though – this is one of those TVs that can comfortably be placed in the centre of a gaming lounge and enjoyed without major compromises.
