LG NANO82T6B vs IFFALCON U85X

The brightness of the LG NANO82T is rather average, especially compared to other TVs in a similar price range. With a peak brightness of approximately 280 nits, it falls short of many competitors offering levels exceeding 400-500 nits. This limitation impacts the viewing experience, particularly for HDR content. Bright areas of the image may lack definition, and the HDR effect fails to deliver the dramatic impact expected from higher-end displays, making the overall image less striking in well-lit scenes.

iFFALCON U85 handles HDR in a rather dual manner – on one hand, it can surprise with a solid peak brightness of around 650 nits, which places it well above average in this price segment. This is particularly evident in full-screen, bright scenes. Examples from movies like Life of Pi or the final test sequences from The Meg prove that the TV can maintain the strength and essence of the HDR effect when the entire panel has to "light up," delivering truly satisfying experiences. However, problems begin in high-contrast scenes, where smaller, bright details appear on the screen; the dimming algorithms prioritize deep blacks to such an extent that they can suppress the brightness of small highlights to just 100 nits, drastically reducing the dynamism of the image and depriving us of the true "punch" we expect from HDR standards. However, the question of colors remains a sweetener; thanks to the use of the PFS phosphor filter (marketed as QLED by the manufacturer), they look very good, achieving nearly 94% coverage of the DCI-P3 color palette, allowing for a rich and vibrant image in most content.

The colour reproduction in the LG NANO82T in Filmmaker mode, while the best factory setting available, does have flaws. The primary issue lies in white balance, where measurements reveal a drop in the level of blue. This shifts towards yellow hues, making the image warmer than intended. Such deviations prevent natural colour reproduction, especially in scenes with white or neutral backgrounds. For instance, in Star Wars, where numerous elements should appear white, the colours deviate noticeably. The Color Checker test corroborates this, showing some shades "escaping" into others, further highlighting the lack of accurate colour rendering.

In terms of contrast, the gamma graph analysis showed a drop to 2.1, falling short of the optimal 2.4. This leads to darker parts of the image appearing brighter, reducing depth and dynamism. Additionally, the EOTF curve, which governs brightness reproduction, shows a slight spike at the start. This can result in an excessive brightness boost in the brightest areas, causing a loss of detail in very bright scenes.

We tested the factory colors in the iFFALCON U85X model in “Film” mode, which is definitely the most reliable among all available settings, although it is still far from perfect. The main problem that stands out in both SDR and HDR content is improper white balance - an excess of blue and red components gives the image a slight purple tint, which undermines the naturalness of film scenes. However, an even greater challenge is the way the television manages its brightness. Analyzing the gamma curve for the SDR signal, we noticed significant instability: instead of sticking to the reference value of 2.4, the device oscillates around 2.2, only to suddenly experience an unnatural jump to around 3.0. In practice, this leads to confusing effects - large bright areas on the screen appear too dark, while smaller elements are unnecessarily brightened. A similar feature can be found in the EOTF curve, which makes the image unpredictable and loses its cinematic authenticity.

After calibration, the colour reproduction in SDR content on the LG NANO82T is impressive. The white balance has been effectively corrected, resulting in natural, balanced tones across various scenes. Gamma adjustments ensure more precise rendering of details in shadows and bright areas, enhancing the viewing experience. These improvements allow the television to perform well in everyday use, delivering solid colour accuracy and well-balanced images in SDR mode.

Unfortunately, the situation with HDR content is less satisfactory. The TV lacks support for a wide colour gamut, limiting the depth and richness that HDR can achieve. The EOTF curve deviates from the ideal, leading to overemphasis on details in brighter areas. This causes noticeable colour reproduction errors, as confirmed by Colour Checker tests. Additionally, the panel's low brightness further hampers HDR image quality, diminishing dynamic range effects and causing colours to appear washed out.

Overall, the TV significantly improves after calibration, particularly in SDR mode. The enhancements to white balance and gamma elevate image quality, offering more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is evident, and the television now performs noticeably better in standard dynamic range scenarios.

After professional calibration of the movie mode, we must admit that the effect is more than satisfactory – the iFFALCON U85X undergoes a true transformation. Color errors in SDR content dropped to a level below 2, making them practically imperceptible to the human eye. We managed to set the white balance almost perfectly, and brightness management (gamma) became nearly exemplary. As a result, with standard quality materials, the television looks simply perfect, and it's hard to find any faults with it.

In the case of HDR signal, the situation has also improved significantly, although here the nature of the device is a bit more pronounced. Color errors have been reduced to around 3, which is an outstanding result in this price range. However, it is worth taking a look at the EOTF chart (available on the right side of the screen in the filters: 4K HDR, gamma / EOTF) to see what is not immediately visible regarding brightness management by the U85. Although the reference line looks decent, in actual film scenes, the television still interprets the signal "in its own way" due to very aggressive local dimming algorithms. Does this disqualify this model for watching HDR content? Absolutely not. It's simply a typical ailment of almost every Mini-LED that has to reconcile high brightness with an attempt to maintain deep black. One just has to be aware of these technical limitations, which are unavoidable in this segment.

The LG NANO82T features a "Smooth Gradation" option for handling tonal transitions in low-quality materials. The "Low" setting improves the most problematic transitions, providing a noticeable and helpful enhancement. However, the "High" setting, while further smoothing tonal transitions, sacrifices some detail in the process. This can be a compromise that not all viewers will appreciate.

The image scaling on the LG NANO82T has some limitations, particularly when displaying lower-resolution content. The TV applies a subtle artificial sharpening, which makes the image appear sharper, but this effect is mainly due to artificial contours. Some users may find this beneficial, as it highlights details more prominently, but for others who prefer a more natural image, it may appear overly processed and artificial. This is a subjective preference that varies from viewer to viewer.

When it comes to scaling the image to 4K resolution, the iFFALCON U85X performs solidly. The device efficiently enhances low-quality signals, making even older materials look clean and clear on the 4K matrix. At extremely low resolutions, such as 480p, you can notice slightly jagged edges (especially on thin lines), but let's face it – this is a scenario you'll only encounter when watching very old footage, so it's not a real issue in everyday use.

However, the digital processing aimed at smoothing tonal transitions is significantly worse. Although the menu features a function called “Gradual Smoothing”, its effectiveness is at least debatable. In practice, it does not effectively reduce banding (color stepping), and worse, it can cause more harm than good. This filter can be too aggressive where it shouldn't be, artificially smoothing out details that should not be touched, such as the natural texture of the face or fine details of the skin's texture. Instead of improving quality, this feature can give the image an unnatural, “plastic” look, so it's best to use it with great caution or, better yet: leave it turned off.

LG televisions, including the NANO82T, come with an interesting motion smoother called TruMotion providing users with control over the quality of films they watch. The TruMotion feature allows adjustment of the motion fluidity on a 10-point scale, offering a personalised visual experience.

However, when it comes to more dynamic content, such as games or action films, the performance falls short. With its 60Hz panel and relatively slow pixel response, motion fluidity is less than ideal. This results in noticeable trailing and less smooth playback during fast-paced scenes.

Overall, the LG NANO82T is a good option for those who primarily watch movies and prefer more subdued content. Viewers who prioritise fast, dynamic motion, may prefer an alternative model.

In contrast to budget constructions, which in dynamic sports scenes may resemble a slideshow, the iFFALCON U85X is a heavyweight contender equipped with a panel featuring a native refresh rate of 144Hz. However, it is worth remembering that in the world of movies, series, or sports, we will mostly operate at 120Hz due to the specifics of image enhancement systems. Such a fast panel is excellent news for gamers and sports fans, as it opens the door to advanced motion settings that simply don't exist in cheaper 60-Hz models.

We manage everything from the "Motion Clarity" menu, where instead of using pre-set, often too aggressive modes, we definitely recommend a custom configuration based on two sliders. The most important of them, reduction of flicker, is responsible for smoothness in films – here, it's best to aim for a value around 4, which will maintain a natural, cinematic character of motion without falling into the artificial "soap opera effect." On the other hand, the first slider, reduction of blur, is the key to success in sports broadcasts. In this case, it's worth going all out and setting it to maximum, ensuring that the image during fast actions on the field remains sharp, and annoying trailing is eliminated.

When playing on the console, the LG NANO82T offers several features that can enhance the gaming experience, though it also has some limitations. Notably, the ALLM (Auto Low Latency Mode) feature stands out, automatically adjusting picture settings to switch the television to low latency mode, which is especially beneficial for gamers requiring quick reactions. Another advantage is the support for HGiG (HDR Gaming Interest Group), ensuring HDR games are displayed as intended by the creators and providing vibrant and realistic visuals. These features contribute to a solid gaming experience, but there are some drawbacks, particularly in fast-paced scenes.

The LG NANO82T has limitations when it comes to advanced gaming features. It lacks support for variable refresh rate (VRR), which affects gameplay smoothness, especially in more dynamic games. The TV's 60Hz panel restricts the ability to use higher refresh rates, a significant downside for gamers seeking smoother gameplay at higher resolutions. Additionally, the absence of G-Sync technology limits image synchronisation, potentially leading to tearing and stuttering during gameplay.

These limitations mean that while the LG NANO82T offers a good gaming experience for casual gamers, it may not meet the expectations of more demanding players seeking advanced features and maximum image fluidity.

These shortcomings may mean that the LG NANO82T does not meet the expectations of the most demanding gamers looking for advanced features and the highest image fluidity.

iFFALCON U85X is an exceptional device for gamers that has virtually everything you can expect from a modern screen for consoles or PCs. Here we find two fully-fledged HDMI 2.1 ports with full bandwidth of 48 Gbps, which opens the door to key technologies such as VRR and ALLM, ensuring smooth gameplay without tearing and with minimal latency. The TV handles high refresh rates at various resolutions without any problem, and a real curiosity is the mode that allows for up to 240Hz when dropping to Full HD quality. The entire system is managed by the Game Bar (a faithful copy from TCL), which allows for instant switching of picture modes, customization of the interface appearance, or even adding a virtual crosshair in the middle of the screen.
