LG OLED C5 vs Sony BRAVIA 5 (XR5)

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.

Looking at similar results in terms of black levels and contrast, we expected the same stable performance as last year's model when it comes to HDR content. Unfortunately – and this must be said plainly – there has been a regression here that is hard to miss. The paradox is that the peak brightness of the Bravia 5 can be impressive: in our synthetic tests, the TV reached around 1000 nits in HDR. Sounds great, right? The problem is that this power doesn't always have a real impact on all movie scenes. When small, pinpoint elements appear on the screen, something that in Sony's case was usually fine-tuned with surgical precision, this time it clearly falters. The algorithms try to maintain deep blacks around small objects, but the side effect is that details can be dimmed to the point of becoming barely visible. One only needs to bring up the example of the movie Sicario 2 – there, in some scenes, small light sources practically vanished as if someone had covered them with dark film.

Of course, not everything looks so dramatic. In simpler, brighter scenes, where the image is filled with more light, the Bravia 5 shows that it can shine: literally and figuratively. At those times, the TV achieves values in the range of 600–800 nits, which we saw both in synthetic tests and during movie screenings. The impression is really positive; the brightness adds dynamism, and the colours look vibrant and fresh. However, there remains a certain dissonance. We feel a slight confusion because it is evident that something has gone in the wrong direction. Technological progress – more zones, more backlight power – has not been supported by the kind of refined image management that we usually associate with Sony. Fortunately, there are elements that have not been compromised and are actually at a very high level. We are talking about colour reproduction. Thanks to the use of the PFS filter, the colour palette coverage is excellent – about 97% DCI-P3 and 75% BT.2020. These values allow for a truly wide colour reproduction, giving films a natural and cinematic character.

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.

Sony Bravia 5 was obviously tested in the best possible mode, which is the Movie mode. Right out of the box, it delivers the most natural colours, definitely better than anything offered by the "eco" or "dynamic" modes, which are more suited for a store display than a living room. However, the Movie mode alone does not guarantee that we can always expect cinematic picture quality. In SDR content, we had no significant complaints – the slightly warmed white balance gave the scenes a golden hue, but it was nothing that was glaring. However, a problem arose with HDR materials. Here, the colour reproduction simply looked bad. The white balance was heavily skewed – with an excess of blue and a clear lack of red. At times, it resembled the store mode of "super vivid picture," where everything is blown out and artificially boosted.

This situation made brightness management seem too aggressive as well. The EOTF graph clearly showed that the television has trouble with overexposing many scenes right out of the box. And while we know what Sony televisions are usually capable of, it was hard to remain indifferent here – that’s why we quickly decided to go for calibration.

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 situation changed dramatically. We managed to tune the white balance so that entire scenes began to look more natural, and the image gained coherence and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously spoiled some shots. Suddenly, it turned out that the Bravia 5 can extract much more from films than the first contact "straight out of the box" suggested. Indeed, if we look at the graphs and compare them with the standards, we can see that the beginning of the EOTF curve slightly strays beyond the reference line. However, this is not so much a calibration error as it is a natural limitation of the Mini-LED technology that cannot be bypassed. Sony, rather than clinging tightly to perfect black, prefers to prioritise the visibility of details – and in practice, it’s hard to disagree with that. We prefer to see the texture of the material on the screen rather than a pitch-black spot where all nuances disappear.

The calibration itself was really beneficial. After about an hour spent on settings, we felt that the image resembled that of the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we love Sony televisions: because once we fine-tune them, they reward us with a picture that captivates for long hours.

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.

Bravia 5 carries the genes of Sony, which remain intact – and thank goodness for that, because we're talking about absolutely exceptional digital image processing. It's no coincidence that for years, it's been considered that TVs from this brand set the standard for how a screen should handle lower quality materials. If someone still watches classic television, old films, or YouTube in lower resolutions, here they get equipment that can turn such content into a surprisingly enjoyable experience. On board, we find several tools worth activating. The first of these is "digital noise reduction." Set to a medium level, it works superbly – smoothing out tonal transitions that usually cause the most trouble in low-quality materials while introducing no artificial artifacts. Importantly, it also doesn't remove the cinematic character, which is the natural grain that is intentionally present in many productions. Another advantage of the Bravia 5 is the upscaling capabilities of the XR processor. The image presented after scaling is soft, yet sharp and clear. The outlines of characters are well-defined, and backgrounds maintain their texture without excessive artificial sharpening. It's hard to find a better TV for watching lower quality materials – Bravia 5 only confirms why Sony is considered the benchmark in this area.

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.

Bravia 5 has a 120 Hz panel, which in itself sounds like an invitation to watch sports, fast matches or spectacular action films. However, the real magic begins when MotionFlow – Sony's proprietary motion smoother – comes into play. Thanks to this feature, we can adjust the character of the picture to our own preferences. The "smoothness" slider allows us to transition from a cinematic feel with a slight "judder" to a theatrical fluidity, where every ball in the match glides across the screen as if on a string. The higher the value, the smoother and more fluid it is; the lower it is, the more film-like and natural it becomes. In the options, we also find an additional setting that Sony calls "clarity". This is nothing more than the BFI function (which inserts black frames) aimed at improving motion sharpness. It sounds great in theory, but in practice, it must be used with caution. Why? Because all higher settings cause brightness drops of up to half, and in some cases, contour doubling also appears. So if we want to use it, we recommend setting it to the lowest level – "1" out of the available ten. That way, we gain a bit better motion sharpness without risking losing half the brightness of the picture.

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.

In the Bravia 5, there is a significant improvement compared to the X90L model from two years ago. The television offers literally everything its predecessor had, but this time the issues that could frustrate gamers have been addressed. Problems with setting the variable refresh rate (VRR) have disappeared, and there are no longer issues with configuring HDR content in HGiG mode. In short: we get a device that simply works as it should, without any hassles. So, the Bravia 5 has everything you can expect from a modern gaming TV – and it can be confidently advertised with the slogan "ready for PS5." That's something we couldn't say about the X90L model. Well done, Sony!

It's just a shame that this relatively high-priced model lacks a full set of four HDMI 2.1 ports. In everyday use, this won’t be an issue for most people, but if someone has a console, soundbar, and additional equipment connected via HDMI, at some point they'll have to choose or juggle cables.
