Philips PUS8079 vs LG QNED80A6A (VA)

The Philips PUS8079 has a maximum brightness of just 202 nits in content with a wide tonal range, which is very low and makes it unsuitable for streaming movies and series in the highest quality. Additionally, using HDR with dynamic metadata doesn’t improve the situation, as the only HDR format available on this model is HDR10+, which is rare and has limited content support. The TV also uses WLED backlighting, which is not optimal and results in only 80% coverage of the DCI-P3 wide colour gamut. This limits the intensity of colours in HDR content.

Let's talk now about how this TV shines. If you expect dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. That's not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamic range" that flagship products offer. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another key category: colors. Here, the PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. Thanks to this process, the TV offers a significantly wider color palette than classic LCD designs. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even at lower brightness, when watching movies in HDR, the colors will be vivid, deep, and properly saturated. The image is not washed out but lush, which is a significant advantage in this price range.

The best factory mode for colour reproduction and fidelity to the director's vision on the Philips PUS8079 was the "Film" mode. However, this setting displayed significant discrepancies between the filmmaker's intent and the actual output. In both SDR and HDR materials (with HDR being less affected), the white balance was off, showing a blue tint similar to store displays, rather than pure whites. When it came to SDR materials, gamma was notably lowered, cutting into the already limited contrast and brightening the overall image. The EOTF curve in HDR content also showed a significant drop below the reference line, making HDR materials appear even darker. The colour accuracy in both SDR and HDR modes was poor, with high deltaE values indicating that the colours were far from their intended representation.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with a VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV “out of the box” serves us a picture with a clear dominance of red and a deficiency of blue. The overall image is very warm, almost hot. Many users might describe this as a “too cinematic” image, approaching sepia. Additionally, there's the issue of the gamma curve – the TV tends to slightly, artificially brighten scenes (the gamma is too low), causing the picture to lose some of its plasticity. The good news is that these are not flaws of the panel, but merely of the software. As always in our tests, we carried out a professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

Fortunately, Philips incorporates advanced image correction tools across its televisions. SDR content benefited the most from these adjustments, with significant improvements in deltaE errors, white balance, and gamma. While the image still isn’t perfect, it is much more watchable, making it easier on the eyes during movie or series viewing. HDR content, however, was more challenging due to the television’s low luminance. While the EOTF curve and white balance improved, the corrections weren’t as effective as with SDR materials. It’s important to note that each unit may have different errors, some larger and some smaller, but the adjustments made were a step in the right direction.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initially too warm white balance and, most importantly, correct the gamma curve. The TV stopped artificially brightening scenes, which added depth to the image. The biggest improvement is visible in SDR content, meaning when watching regular television, YouTube, or in games without HDR. Here, the QNED80A shows its class – color reproduction errors (DeltaE) dropped below a value of 2. In technical terms, this means that the errors are practically unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Even though we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the TV still "interprets" the image in its own way. This is due to the nature of the edge-lit local dimming used and the fact that LG gives the calibrator a very limited range of control over this parameter. In short: the TV struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is much more accurate and pleasant to the eye than in factory settings, even if it still falls short of studio ideal.

Let us revisit the topic of tonal transitions, this time in the context of overall image quality enhancement. As shown in the photo on the left, the gradation improvement feature delivers excellent results. It provides multiple settings, each offering noticeable benefits without softening the film grain effect. Once again, it must be emphasised that this feature is the standout advantage of the tested television.

On the other hand, the television’s performance in image scaling leaves much to be desired. Fine details often appear heavily jagged, with a noticeable white halo around figures. Additionally, the significant artificial sharpening detracts from the overall image quality.

In this category, the QNED80A proves to be a real "dark horse." It's a fantastic, affordable television for those who often watch lower quality materials – for example, from traditional cable TV. The processor used here handles upscaling exceptionally well, meaning it enhances low resolution to native 4K. The image after processing is natural, smooth, and most importantly – not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality material. This feature works really effectively, eliminating the annoying "banding" of colors in heavily compressed video. However, we must remain vigilant. Remember that we are not dealing with a top-tier processor known from flagship OLED models. In more challenging scenes, the system may struggle and introduce minor artifacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, as in most cases, the improvement in quality is noticeable to the naked eye.

This paragraph will be notably brief due to the absence of even basic motion-smoothing functionality, which is unsurprising given the device's budget-oriented nature. The VA panel used here is not known for exceptional sharpness and is instead associated with high contrast and slower response times, as confirmed by the matrix analysis results. Photos captured during fast motion reveal typical motion blur for this type of panel. While not ideal, the television could be conditionally suitable for watching sports, though viewers should expect less-than-optimal motion clarity. Additionally, films may exhibit noticeable stuttering due to the lack of any motion-smoothing features, even basic ones.

We move on to a matter that may be decisive for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This TV is equipped with a panel that has a native refresh rate of 60Hz. There's no point in hiding it – at this price, we expected more because we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strong suit of this screen. Fortunately, LG has equipped the TV with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother while still looking natural, without the artificial "TV theater" effect.

The Philips PUS8079 provides only basic gaming features, including ALLM, VRR, and a Game Bar. The key highlight is the inclusion of dynamic frequency adjustment, which ensures a smooth image with minimal screen tearing—an impressive offering for this price range.

A notable benefit for gamers is the presence of the Game Bar, allowing adjustments to be made "on the fly" without needing to exit the game. Importantly, this feature retains options found in higher-end models, such as shadow enhancement for improved visibility in darker areas and a colour filter designed to assist gamers with visual impairments.

Since we have established that the QNED80A is a 60Hz panel television, we must say it directly: we will not be playing here at 120 frames per second in any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for "casual" gamers. LG has decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) ranging from 48-60Hz and an automatic game mode ALLM, which quickly reduces input lag upon detecting a console. We manage all of this through a very convenient, purple Game Optimizer menu (Player Panel), which has already become LG's trademark. The manufacturer deserves big credit for consistency regarding HDR. Although the television does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a moderately bright screen, HDR gaming is clear, and details in shadows and highlights are accurately reproduced, rather than "cut off."
