TCL MQLED85, or model C765, is a television that can really surprise, especially in this price range. It is one of the cheapest models with mini-LED technology, which is immediately evident in the picture quality. The blacks are deep, and the brightness is sufficient even in a brightly lit room. With a large number of dimming zones, watching movies in the evening is a pleasure – the blacks are truly deep, and the image in dark scenes looks clear. However, it is not perfect – in some shots, minor issues can be noticed with small bright elements, but this is really a minor detail compared to what this model offers. Google TV works wonderfully here – there are plenty of apps, and using the system is simply convenient. Voice control in Polish works flawlessly, which can be particularly useful if you don’t want to type in movie titles using the remote. Of course, there are minor shortcomings, such as the lack of recording, but these are not things that hinder day-to-day use. For gamers, it is also a great option. HDMI 2.1 support, VRR, and low input lag mean that the television handles consoles well and competes without issues with more expensive models from Korean or Japanese manufacturers. In this price range, it is hard to find something better when it comes to smooth and responsive gameplay. During testing, we encountered a few minor software issues, but it’s hard to say if that’s a serious downside. We hope that TCL will release updates, so there is a chance that this issue will be quickly addressed. TCL MQLED85/C765 is an excellent choice if we are looking for a television with good picture quality and modern features at a reasonable price. It is a model that combines affordable mini-LED technology with a user-friendly Google TV system and also performs excellently in gaming.

Overall, it’s hard to fault the LG OLED C4, as it offers exceptional features at a competitive price.

TCL MQLED85/C765 stands out with its use of a VA panel and Mini LED backlighting, which makes a huge difference compared to traditional backlighting systems. Mini LED, thanks to significantly smaller diodes, allows for more precise control of the screen's backlighting, resulting in much better contrast and deeper blacks. The 55-inch model we are testing boasts an impressive number of over 700 local dimming zones, providing exceptional precision in displaying images. It is worth noting that the number of backlighting zones may vary depending on the screen size - for larger diagonals, the number of zones naturally increases due to the larger screen area, allowing larger sizes to achieve better results in terms of contrast and black levels. Thanks to the vast number of zones, the TCL MQLED85/C765 achieved a result comparable to OLED screens on our first test slide from the movie "Oblivion," offering nearly reference-level contrast. But what will happen when we test this model in even more demanding conditions? How will the TV perform in tougher scenarios? Overall, the TCL MQLED85/C765 performs very well in displaying blacks, but in some cases, the local dimming algorithm is not perfect. On dark backgrounds, smaller bright elements can lose sharpness and brightness, as confirmed by our recent slide from the Pioneer Kuro test disc. Despite some imperfections in the local dimming algorithm and the slight presence of the HALO effect (a bright halo around bright objects on a dark background caused by imperfections in the screen's local dimming), the results achieved by the TCL MQLED85/C765 are impressive, especially considering its price. This TV offers contrast and black depth that can compete with models that are even half again as expensive.

The LG OLED C4, as the name implies, utilises an organic matrix developed in-house, making it one of the most recognisable series on the market. With over 10 years of experience producing self-emissive panels, LG has continually refined its designs, and the 2024 models are the pinnacle of this progress. An OLED screen ensures flawless contrast and black levels, immersing viewers in the director’s vision. OLED technology stands out for its lack of traditional backlighting, instead relying on current flowing through organic pixels. This design allows for precise image control, eliminating issues like dimming of fine details or halo/blooming effects.

In our test scenes, two standout features were immediately apparent: perfect light separation and an abundance of detail in "The Revenant." Crucially, the C4 displayed the distinct green tint some televisions attempt to correct, without issues. The LG OLED C4 excels in delivering exceptional contrast, resulting in incredible depth and richness. Test results confirm that the black levels are flawless, particularly in high-contrast scenes. Ultimately, the LG C4 offers an unmatched contrast ratio, delivering a visually stunning experience whether watching movies or gaming.

The TCL MQLED85/C765 television performs well with HDR handling. In the tested movie scenes, where the screen is covered at 100% brightness, the model achieves impressive results around 1000 nits, providing intense and realistic representation of HDR content. However, similar to contrast, the dimming algorithm may show some limitations. Despite the large number of Mini LED zones, the television does not always manage to "stun" the user with brightness in very challenging test scenes. For example, in a scene from "Life of Pi," where a bright moon appears against a dark background, and in another scene from "Sicario 2," where a very bright light effect is visible against a dark background, the television did not reach maximum intensity. For users expecting perfect HDR performance in such extreme cases, the TCL MQLED may be slightly disappointing. However, regarding colors, the television stands out with a very high color gamut coverage of DCI P3 at 95%, which is an impressive result comparable to much more expensive models. The TCL MQLED85 / C765 offers support for various HDR formats, including Dolby Vision and HDR10+, which is essential for cinema image enthusiasts. Although this model achieves brightness over 1000 nits, the TCL MQLED85 may struggle to reflect details in very high contrast scenes. For better HDR quality control, the C765 is equipped with dynamic tone mapping, making the image more realistic and natural depending on the content.

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.

TheTCL MQLED85/C765 television was tested in movie mode, which, although it seems to be the best setting from the manufacturer, is not without flaws. The color reproduction in HD/SDR mode MQLED85 shows certain shortcomings. In the analysis of white balance, there is a significant lack of blue color, which can affect the overall picture quality, especially in bright scenes where blue hues are crucial for natural representation. The overall image may then seem too warm. As for gamma contrast, the graph shows a significant jump above the reference line of level 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to a loss of detail in blacks. Then, for most of the time, the values are below this line, which can lead to a loss of detail in the brighter parts of the image. Such a distribution can negatively affect the perceived image quality, especially when watching regular HD television.

In the case of 4K HDR image quality of the TCL MQLED85/C765, there is a noticeable excess of red color in the analysis of white balance. Such an excess can significantly affect the viewer's experience, leading to several significant effects. First of all, too much red can make other colors, such as green or blue, appear muted or unnatural. This distortion of color balance can result in an overall impression of "oversaturation," which detracts from the image's naturalness and authenticity. Regarding contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in the bright areas of the image. However, the exception is the beginning of the graph, where the EOTF line is below the reference one, which may lead to excessive dimming of small light elements.

Users should be aware that despite using the best mode, which is movie mode, the television is not free from flaws in the context of picture settings, so it is worth considering adjusting the settings to achieve better results.

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.

After professional calibration of the TCL MQLED85/C765 television, its color properties in movie mode have significantly improved, resulting in much more satisfying visual experiences. Both in SDR and HDR modes, the white balance shows no serious errors, and the graph appears much better harmonized. Users can now enjoy natural color reproduction, which is essential for achieving an authentic experience while watching movies. It is worth noting that in HDR content, there may be minor color reproduction errors at the end of the graph, but they are significantly smaller than before calibration. This makes characters and landscapes more realistic, enhancing the depth of immersion in the story.

Regarding contrast, the gamma curve, responsible for HD quality, has been completely free of drops below the reference line, which means better detail visibility in dark scenes. However, there is still a slight boost at the beginning of the graph, which may affect the perception of bright elements. For HDR content, the EOTF curve also shows smaller errors, although certain issues in reproducing midtones may still be noticeable. The EOTF curve measured on real film scenes still shows a significant brightness boost, making the image appear more intense but artificially brightened. This is a typical issue for TCL brand televisions, which may appeal to untrained viewers but can be annoying for those more familiar with the ideal picture.

What benefits does professional calibration bring for movie enthusiasts? Thanks to it, watching becomes even more realistic and immersive, allowing every scene to be experienced fully, maintaining details and natural colors.

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 fluidity of tonal transitions in the TCL MQLED85/C765 television is decent, although certain issues are noticeable in both bright and dark test scenes. In particular, color transitions are visible in a scene from the movie "The Green Knight," where the red color of the water transitions to black. Despite these imperfections, the overall quality of gradation is acceptable and does not overly spoil the visual experience. The television handles most scenes well, offering satisfying tonal transitions, which contributes to an overall enjoyable visual experience that will not ruin our cinematic impressions.

The fluidity of tonal transitions in LG TVs has long been a delicate issue, as the manufacturer, despite excelling in many areas, has consistently faced challenges in this aspect. However, the tested TV performed notably well in this regard. Issues were primarily confined to darker scenes, particularly the final two, where imperfections were more apparent. Interestingly, this model delivered better results in tonal transitions than LG's flagship model, the G4, showcasing a commendable improvement in this area.

We will now take another look at the tone transitions in the TCL MQLED85/C765 television, but in the context of poorer image quality. Despite the presence of the "Gradual Smoothing" option, when set to "low," the effects are practically invisible, disappointing users expecting an improvement in image quality. On the other hand, setting it to "high" brings minimal results, and worse, it can blur significant details, negatively affecting the sharpness and clarity of the displayed image. However, in terms of image scaling, the television successfully displayed the image without overscan, which means we do not lose any part of the view. The image looks quite decent, and details such as tree branches or the outlines of models do not show significant fraying, which positively influences the visual quality.

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.

TCL MQLED85/C765 is equipped with a standard refresh rate matrix of 120 Hz, with the possibility of increasing it to 144 Hz when connected to a powerful computer. The television also offers a multi-stage motion smoother, which mainly serves users who want to improve motion smoothness in films. It allows for the adjustment of the effect's intensity on a scale from 0 to 10, enabling precise matching of image smoothness to individual preferences. The matrix's response time is decent but not perfect. We can observe ghosting occurring behind both dark and medium objects.

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.

TCL MQLED85/C765 has received an impressive rating in the gaming features category, making it an excellent choice for gaming enthusiasts. The television supports all the latest technologies that significantly enhance the gaming experience. Among the key gaming features is ALLM (Auto Low Latency Mode), which automatically switches the television to low latency mode, minimizing response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) supported in the range from 48 to 144 Hz eliminates stuttering and screen tearing in dynamic gaming scenes. Additionally, the television supports Dolby Vision Game Mode, which provides better image quality in games with exceptional color depth and contrast. TCL MQLED85/C765 also features a decent but not the best implementation of HGiG (HDR Gaming Interest Group), optimizing HDR game display, but in the case of TCL, it causes bright details in white, resulting in some elements blending into a white spot - we can read more about this in the color reproduction section. It supports various resolutions such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing gamers to take advantage of higher image quality and better fluidity. The Game Bar feature allows for easy switching between game settings and quick control of parameters, significantly facilitating the adjustment of the television to individual needs.

This is a reference-level result that ensures smoothness and responsiveness, crucial for both gamers and those engaged in video editing. However, it is worth noting that there is a certain issue related to font display on dark backgrounds. When zooming in on the tested font image, it can be seen that horizontal lines are darker compared to vertical ones. This means that the sub-pixels in the television do not fully illuminate in this case, which can affect the quality of the displayed text. Nevertheless, the overall performance of TCL MQLED85 as a computer monitor is very good and will certainly meet the expectations of many users.

When paired with a PC, the LG C4 delivers excellent performance, largely due to its impressively low latency of 13.5 ms, ensuring a near-instantaneous response between the mouse, eye, and screen. This makes it an ideal choice for tasks requiring precision and speed.

One of the most crucial aspects of using a TV as a monitor is text readability, and in this regard, the LG C4 excels. The text appears sharp and clear, although enabling the passthrough option in the settings is necessary to optimise font sharpness.

The RWBG pixel layout is another advantage, as it does not significantly affect the clarity of fonts or letters—a notable improvement compared to Samsung's QD-OLED panels. Whether using Windows or macOS, the LG C4 ensures a smooth and satisfying user experience for work or general PC use.

The viewing angles on the TCL MQLED85 television are not its strongest point. The use of a VA panel means that the picture loses a significant amount of brightness when viewed at an angle. When the viewer's position changes, especially when watching with a larger group, colors may appear less saturated, and the contrast may be less pronounced. For this reason, it is recommended to sit directly in front of the screen to fully enjoy the picture quality. Although the television offers excellent color reproduction from a direct view, the loss of brightness and detail at an angle can be problematic for those planning to use the TV in a larger room or from various positions.

One of the undeniable strengths of OLED panels is their exceptional performance for group viewing, allowing for consistent image quality from a range of viewing angles. The LG C4 upholds excellent contrast, colour saturation, and fidelity, ensuring a satisfying experience for viewers in different seating positions.

While it lacks the enhancements provided by MLA (Micro-Lens Array) technology, the C4 still delivers impressive results that most owners are likely to find highly satisfactory. However, at sharper angles, a slight greenish tint can sometimes be observed. This is a known characteristic of LG’s WRGB panels without micro-lens technology and, unfortunately, is an inherent limitation that cannot be mitigated.

MQLED85 performs decently in daylight conditions, and it's worth noting the satin finish of the panel. Although it doesn't excel at reducing reflections, it offers satisfactory performance in various lighting conditions. An average brightness level above 600 nits is an impressive result, allowing for comfortable viewing even in well-lit rooms. As a result, the television works well both during the day and for evening movie sessions, providing satisfactory image quality.

The maximum brightness of the LG C4 in SDR content reaches 367 nits, which is an impressive result for an OLED television and ensures comfortable viewing, even during the day. Two notable aspects enhance the experience. First, the glossy coating on the panel effectively contains light reflections, preventing them from spreading across the screen and disrupting the image.

Secondly, the brightness of the screen at 100% white fill measures approximately 220 nits, a significant improvement over earlier OLED models, which often struggled to achieve even half this level.
