Philips PUS8359 (VA) vs LG NANO81A / NANO80A

The Philips PUS8359 has low brightness levels; however, dynamic tone mapping works surprisingly well, making it worth praising!

If you're counting on HDR in the NANO81A to bring tears to your eyes, I have to disappoint you. This TV is simply too dark to show what this format is really about. With a brightness of just 250 nits, HDR here essentially exists only on paper. In practice, during a viewing session, it's very hard to distinguish whether we're watching high dynamic range content or regular SDR – it simply lacks that "punch" of light in bright areas of the image. But, to not have all criticism, we do have a glimmer of light at the end of the tunnel – and it’s quite clear. It's about color gamut coverage. Here, the NanoCell filter shows that it's not just marketing nonsense. Our measurements indicated that the coverage of the DCI-P3 space is around 88%. This is really a solid result that positions this model significantly above typical budget models based on regular white LED lights without any filters. Of course, it's still a bit lacking compared to the level of quantum dot TVs (QLED) or advanced panels with PFS filtering, but for this price range, the colors are surprisingly saturated and vibrant. It's just a shame that this low brightness doesn’t allow them to fully "spread their wings" with the Nano filter.

The best factory mode for fidelity to the source material was the "Film" mode, which we used during our tests. As with all factory modes in televisions, it has flaws, and we’ll now examine what went wrong in both SDR and HDR materials. In both cases, the white balance showed an excessive dominance of green and red, resulting in a yellowish tint across the entire image. This caused issues such as yellowed whites and problems with skin tones. This was clearly illustrated on the "ColourChecker" palette, where each tested sample shifted towards warmer equivalents. The foundation of the image lies in contrast and black levels, represented by gamma charts and the EOTF curve. Looking at the gamma chart, we saw a real rollercoaster, with both elevated and lowered gamma. The elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, as it only mildly brightened the image.

For every movie fan, the natural choice in LG televisions is the Filmmaker Mode. This mode is designed to display the image as the director intended – without unnecessary "enhancements." Unfortunately, in the case of our test unit NANO81A, the factory settings left something to be desired. The main issue turned out to be white balance. Measurements showed a clear deficiency of blue color, which practically translated to many scenes having a slightly yellowish, almost "too yellow" tint. The white was not perfectly clean, which detracted from the freshness of the image. Additionally, brightness management was not ideal either – the factory-set gamma was too low. The image often appeared oversaturated, as if it had been pulled too much from the shadows, losing its naturalness and depth. Fortunately, LG, even in this relatively low price segment, does not block access to advanced settings. The calibration capabilities of this model are immense, which is a big plus for those who like to "dig around" in the menu. We decided to approach the topic in our own way and see how much we could extract from this panel with professional calibration.

Philips offers a wide range of image calibration tools in its higher-end and more affordable models. We used these tools, but the process was not as straightforward as many might expect. While we adjusted the white balance, significantly improved the gamma, and refined the EOTF curve in both SDR and HDR content, the deltaE errors remained extremely high. Several factors contribute to this situation, including the limited coverage of the DCI-P3 colour gamut and the unit's maximum brightness in HDR materials.

After calibrating the NANO81A, it's a completely different television. What LG offers in terms of image enhancement tools even in such an inexpensive model deserves a big plus. We were able to completely eliminate that annoying yellowing of whites and make the colors natural, juicy, and simply "true." In SDR content (such as regular TV, YouTube, or older films), the picture now looks infinitely better – it's clear, well-balanced, and no longer strains the eyes with strange hues. It's evident that this panel has considerable potential, which is simply wasted by poor presets out of the box. However, we have one serious reservation that calibration cannot fully overcome – it's about brightness management in HDR mode. The algorithm LG uses in this model is designed very conservatively. The television deliberately dims the image in HDR to avoid overexposing an already weak black from the IPS panel. The developers faced a choice: either provide more light and accept that black will turn light gray, or reduce the brightness to maintain any contrast. They chose the latter. Nevertheless, after our adjustments, watching anything on the NANO81 is significantly better.

In this paragraph, we will take a look at two functionalities. We will once again look at the function responsible for tonal transitions, but we will also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction." As we have established, it quite effectively smooths out imperfections. However, we need to point out two things: we cannot enable it for HDR material and it blurs details in films.

The tested television cannot boast the best image scaling. There is a noticeable overall blurriness of the image, but what is worse, it blurs details. This is particularly visible on the branches and the model's hair. Additionally, a characteristic white halo can often be seen surrounding characters.

It often happens that cheap 4K panels mercilessly bring all the "dirt" and imperfections of lower resolution materials to light. However, in the case of the LG NANO81A, the situation is quite different. It’s a really solid performer when it comes to handling content that is far from ideal. The built-in processor does a great job with upscaling. Even older recordings look quite decent on this screen – the image is coherent, cleaned of digital noise, and simply pleasant to the eye. A big plus is the gradation reduction feature that you will find in the settings. It is exceptionally effective in combating color banding, which is a lifesaver when watching low bitrate materials, for example from some streaming services or older files from the internet. However, it is worth maintaining a certain vigilance. Since we are dealing with a less efficient chip than in LG's top models here, too aggressive an adjustment of this option can sometimes result in minor artifacts or a slight blurring of details. Despite this risk, I definitely encourage experimentation with this feature – in many cases, it can save the viewing experience and make low-quality material fully watchable.

The Philips PUS8359 is not the best choice for watching sports. This is primarily due to the absence of even a basic motion smoothing feature, which given the price point, is not entirely surprising. Additionally, the television uses a VA panel, which, while offering high contrast, is not known for its sharpness or fast response times. As demonstrated in our analysis, fast-moving scenes often result in noticeable blurring, a common issue with this type of panel.

Although it is not an ideal option, the TV can be used for sports viewing with some compromises, particularly regarding motion sharpness. It's also worth noting that films are prone to stuttering since the TV lacks any form of motion smoothing, even the most basic functionality.

In terms of motion fluidity, the NANO81A unfortunately has a few drawbacks. The TV is based on a panel with a refresh rate of 60 Hz. If you're looking for perfect sharpness in dynamic football matches or fast-paced action games, you might feel somewhat unsatisfied. With such a low native refresh rate, fast-moving objects on the screen will always be a bit blurry.

Unsurprisingly the Philips PUS8359/12 offers only the most basic support for consoles. When connecting a console, users can rely on features like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). VRR is particularly commendable, as even some higher-end models can struggle with this functionality.

A noteworthy addition is the implementation of a dedicated GameBar, which allows for on-the-fly adjustments without needing to exit the game, minimising unnecessary distractions. This feature also provides options to tailor gameplay for individuals with disabilities, making it a highly commendable inclusion.

NANO81A is unfortunately not a device designed for e-sports. The lack of support for a 120 Hz signal is a fact that users planning to purchase this model must simply come to terms with. Nevertheless, LG engineers have worked hard to squeeze the maximum capabilities out of this 60 Hz panel, offering a set of features that genuinely enhance the gaming experience. Above all, the television supports VRR technology (in the range of 48–60 Hz) and ALLM. As a result, the image remains stable and does not "tear," and the device automatically switches to low-latency mode as soon as it detects a signal from the console. Managing these settings is incredibly simple thanks to a dedicated system overlay that allows for a quick overview of parameters without leaving the game. A significant advantage is the support for the HGiG format. This solution is crucial for owners of modern consoles, as it enables the TV to correctly "understand" the intentions of game developers regarding HDR tone mapping. In practice, this helps avoid the effect of "blown out" bright spots, such as clouds or light sources, which unfortunately is a common issue in budget LCD televisions.
