LG OLED C4 vs SONY BRAVIA 3

The HDR performance of the LG OLED C4 is impressive, firmly placing it in the higher tier. Most films exceed 700 nits, delivering a highly realistic image. While none surpass the 1,000-nit mark, the combination of these results with the TV’s infinite contrast and perfect blacks significantly enhances the visual experience. The final scene, with a full-screen flash of sunlight, is slightly less bright than the others but still maintains a solid level of brightness. Another highlight is the excellent DCI-P3 colour gamut coverage, which ensures incredibly vibrant colours. The HDR technology in the LG OLED C4 delivers exceptional colour and detail reproduction. The dynamic tone mapping feature optimises brightness levels, ensuring ideal light reproduction in every scene, even in the most demanding high-dynamic films.

Bravia 3 does not hide the fact that it belongs to the group of televisions that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value balancing on the borderline where one can still speak of any HDR effect. For some, this is an acceptable level; for others, it is rather typical for SDR materials, where spectacular highlights or vivid contrasts are not expected. The impression is that this is not a television for those focused on the highest image quality in demanding film content. However, this does not mean that we won't find any advantages here. Compared to its predecessor, the X75WL, Bravia 3 has gained an additional PFS filter, functioning similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 color gamut has been significantly expanded and reaches over 91 percent, which in practice provides more saturated colors and a more pleasant image texture. As a result, even everyday content looks a bit livelier, and movies and series can surprise with their colorful presentations, despite the limitations in brightness itself.

The best factory mode on the tested television was "Filmmaker," which served as the basis for all evaluations. In terms of colour reproduction, this mode performed reasonably well; however, certain flaws significantly detracted from the overall viewing experience. The most fundamental issue was the white balance, which exhibited a noticeable dominance of red, skewing the image characteristics. This resulted in a pronounced yellow tint to whites and a general shift of all colours towards warmer tones.

The gamma, an equally crucial—if not more important—aspect, was notably lowered, leading to a marked reduction in contrast. Additionally, the television frequently lost detail at the start of the gamma curve. These issues were most apparent in SDR content.

When examining HDR materials, the same yellowing effect in the white balance was observed, as seen with SDR content. However, the EOTF curve, which replaces the gamma curve for HDR, was near perfect and left little room for criticism.

We primarily tested the Sony Bravia 3 in movie mode, which immediately proved to be the best choice among the factory settings. The picture is not perfect, but compared to the eco mode that the TV suggests right out of the box, the difference is significant and for the better. In movie mode, one can notice a certain problem—the image seems too warm, which results from a lack of blue in the white balance. Despite this, in SDR content, the final effect can still be considered quite decent and satisfying for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed significant deviations, and poor brightness management combined with limited color gamut coverage further exposes the shortcomings of the image in this mode. All of this makes HDR on the Bravia 3 look unconvincing and can spoil the impression left by the quite decent SDR content settings. Fortunately, this is not a situation without a solution. Various errors can be somewhat mitigated, and some can even be completely corrected through professional calibration. Therefore, we decided to check how the TV would perform after such adjustments.

As mentioned, LG televisions come with advanced tools to facilitate an accurate calibration process. By utilising these tools, we meticulously adjusted the image to align with the director’s original vision. Without overstating, the results were outstanding. Both SDR and HDR content now achieve a level of visual fidelity that reflects how films are intended to be seen.

Examining the colour accuracy on the "ColourChecker" palette reveals impressive results, with almost all colour errors falling below a delta of "1," aside from two minor exceptions. Post-calibration, the LG OLED C4 demonstrated a marked improvement in colour reproduction, particularly in SDR and HDR modes. Testing the TV after calibration highlighted its capacity for delivering exceptionally accurate colours, underlining the high calibre of this model. The LG C41LA offers a stunningly precise colour palette, sure to satisfy even the most discerning viewers.

The calibration allowed us to extract significantly more from ChooseTV 3 than we could have expected at the beginning. First and foremost, we managed to address the shortage of blue color, which previously caused a noticeable warming of the image. After a slight adjustment in white balance, most of the errors in Color Checker measurements for SDR content practically disappeared. The shades of white gained a natural quality, and brightness management in gamma stabilized to a level that is nearly perfect, not exceeding the threshold of human eye perception. Therefore, it can be confidently said that in SDR content, after a few tweaks in settings, ChooseTV 3 performs really excellently. HDR content, however, fares much worse, although it is still definitely better than before calibration. The white balance has been corrected, but the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which immediately stands out. Color-wise, the effect has also improved, although it is far from ideal—many errors still exceed the threshold of four or even five delta E units, meaning they remain visible to the human eye. It was already clear before that ChooseTV 3 is not a television designed to amaze with HDR quality. Nonetheless, it is gratifying that in SDR content, after calibration, the image can look really great, and in this category, the television pleasantly surprised us.

Let us revisit the function responsible for smooth gradation and consider its role in improving lower-quality materials. The default smoothing of tonal transitions, while decent, can be further enhanced. The feature includes a slider for adjusting its strength, and we recommend selecting the first option. This setting strikes a balance, offering excellent results without compromising important details through unnecessary blurring.

The image scaling on the LG C4 is commendable, though not entirely without flaws. By default, the image appears slightly sharper, though not to an intrusive degree. While jagged edges on elements like trees are occasionally visible, this issue is relatively minor compared to similar offerings from other manufacturers.

Bravia 3 brings something more to the Sony television family than just a common name. It stands out primarily for its ability to improve the quality of weaker materials thanks to the applied processor. Of course, we won't find the advanced XR chip known from more expensive models here, but it must be acknowledged that the image at a lower resolution looked surprisingly good. Scaling worked effectively, and most parts of the screen were free from the typical excessive jagged edges found in budget constructions.

The feature that enhances the fluidity of tonal transitions is also worth noting. In the high setting, it works really well, effectively masking the imperfections of gradation without significant loss of detail. It does happen that the algorithm overly smooths elements that should remain sharp – for example, faces – however, in overall terms, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower-quality content.

The LG G4 supports a maximum refresh rate of 144 Hz, achievable only when connected to a high-performance PC. Otherwise, the television operates at a maximum of 120 Hz, the recommended setting for viewing sports or content with fast-paced motion. For those prioritising smooth image quality, LG has included a versatile motion smoothing feature called "TrueMotion." This function is split into two adjustable sliders: De-Blur, which sharpens moving images, and De-Judder, which reduces jitter. Both sliders offer a range of settings from 0 to 10, enabling users to fine-tune the motion smoothness to their preference.

The LG OLED C4 boasts an impressive average response time of less than 1 millisecond, as confirmed by our measurements. This results in exceptional image clarity, far surpassing LCD televisions, which often have response times of several milliseconds. This clarity is evident in tests like the "UFO Test," where no trailing blur is visible behind moving objects.

The fluidity of motion has never been a strong point of TVs equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that might appeal to those who are more sensitive to the way images are displayed. We are talking about the proprietary Motion Flow motion smoother, which offers users a lot of adjustment options. Thanks to it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic stuttering that many simply associate with the film atmosphere. These features work with content at lower frame rates, such as movies and series recorded at 24 or 30 frames per second, which are the materials we encounter on a daily basis. It is precisely in this area that the motion smoother proves to be one of the most important features in everyday use of the television, and here the Bravia 3 performs really well.

The LG C4, like nearly all OLED televisions from the manufacturer, excels in its compatibility with consoles and PCs. With the inclusion of four full-bandwidth HDMI 2.1 ports supporting 48 Gbps, the TV incorporates a range of features to enhance the gaming experience. Notably, it offers simultaneous support for FreeSync and G-Sync, making it an ideal choice for gamers using AMD or Nvidia graphics cards. For those seeking the best possible gaming quality, the integration of HDR Dolby Vision and HGIG mode is particularly impressive. HDR Dolby Vision operates with remarkably low input lag across all settings, ensuring smooth and responsive gameplay.

A standout feature in LG's televisions is the GameBar, which allows users to adjust settings in real-time without leaving the game. This includes options for customising the image for viewers with visual impairments, a thoughtful addition. Additionally, enabling VRR (Variable Refresh Rate) does not result in a loss of contrast—a benefit of the OLED panel's self-emissive technology, eliminating the need for conventional backlighting. While some slight flickering of grey tones may occur, this is a characteristic of VRR technology across all manufacturers.

In summary: The LG C4, like the brand's other OLED models equipped with high-refresh-rate panels and HDMI 2.1, provides a seamless and immersive gaming experience. For gamers demanding top-tier performance, this TV is an outstanding choice.

Bravia 3 is not a device for e-sports enthusiasts or fans of late-night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports wraps up the topic before it can even develop. This is a TV for casual gamers who, after work, want to fire up FIFA or racing games, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has added a few nice extras so it’s not too barren. ALLM works as it should, automatically switching the TV to game mode (low latency). We even find a simple Game Bar here that is clear. However, the biggest curiosity is the PlayStation Portal app. With it, you can launch games from PS5 wirelessly and immediately see them on the TV screen. It sounds great, but it only takes a few minutes to feel significant delays. In our opinion, it’s more of a showcase of capabilities than something usable on a daily basis. If someone really wants to play, it’s better to connect the console with an HDMI cable right away and forget about wireless problems.
