LG OLED C5 vs SAMSUNG S95F (TANDEM OLED 83")

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.

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also enchants with its HDR effects. In test movie scenes, such as “Life of Pi” or “Sicario 2,” where smaller light points dominate – stars in the night sky, the glow of the moon, or headlights – the TV easily achieves brightness levels surpassing 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and places this model in the same category as the best Mini-LED constructions.

The limitations of organic panels only emerge in full-screen scenes completely filled with white. In the case of this model, for example, in the final scene of the film The Meg, brightness drops to around 1000 nits – slightly lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about an outstanding result, unprecedented in OLED TVs of this size. The colour reproduction is equally impressive. The new Tandem OLED panel nearly catches up to QD-OLED TVs, offering excellent coverage of a wide colour gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

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.

The best picture mode right out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, though not without flaws. The image is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. Average colour errors hover around values of ΔE 3–4, which is on the borderline of what most people can detect with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance isn't such a big issue – the real obstacle is how the television manages brightness. In many scenes, the image looked as if it had been blown out, and details in the blacks could completely vanish. The final effect didn't do justice to what such a device is capable of, leading to significant colour inaccuracies. It's hard to understand why such a factory characteristic was chosen, as the perception of HDR in this rendition was definitely not what it should have been.

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 S95F shows what it can really do. The white balance has been straightened out, and minor inaccuracies have been corrected, making the image in SDR content look nearly exemplary. Colour differences have fallen below the level that the human eye can detect – looking at the screen, one just gets the impression of complete naturalness and harmony of colours.

In HDR, the improvement is equally noticeable. The TV handles brightness much better, and there’s no longer the 'blowing out' of the entire frame. Bright scenes are more controlled, and blacks retain more detail, though sometimes a slight brightening of the overall image can still be noticed. However, this doesn’t change the fact that after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we’re watching movies in SDR or spectacular productions in HDR.

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.

The Samsung S95F model features noise reduction, aimed at improving the fluidity of tonal transitions. Its effectiveness is difficult to call ineffective – on the contrary, it can excessively interfere with the image. Older films or materials of lower quality, such as those from YouTube, take on a soft, smoothed character reminiscent of a painting effect thanks to this feature. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the feature does not blur significant details, so its use is more a matter of preference. If someone prefers a slightly polished and smooth image, it’s worth turning it on, but in our opinion, the most sensible setting is “Standard”.

Upscaling leaves a better impression. The S95F efficiently enhances the quality of lower resolution content – even 576p videos look quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to the competition – such as the Sony Bravia 8 (II) or LG G5 – it is noticeable that those models can extract a bit more from the image. However, one inconvenience to remember is that in the case of older films and photos, there is a problem with overscan, which causes a slight trimming of the left edge of the image.

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.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion also makes a huge impression. The panel in native 4K resolution offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sport look fantastic. Additionally, the manufacturer has added a motion smoother and a motion blur reduction system, allowing each viewer to customise the picture to their own preferences – whether a more 'choppy', cinematic effect or a smooth, almost theatrical spectacle.

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.

Low motion blur and phenomenal motion fluidity, hallmarks of the OLED panel, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will feel the slightest limitation here. Onboard is a full set of gaming features: variable refresh rate VRR, automatic game mode ALLM, and an excellently implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particularly noteworthy is Game Motion Plus, Samsung's proprietary motion smoother. It can add additional fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Yes, there's no support for Dolby Vision in games, but it's hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favourites for the title of the best gaming television on today's market.
