Philips OLED809/819 vs LG NANO81A / NANO80A

The Philips OLED 809 delivers a highly satisfactory HDR effect. The television can reach luminance levels exceeding 900 nits in most scenes, and in some cases, even surpassing 1000 nits. This brightness ensures a rich and immersive experience for HDR content with a wide tonal range. The only exception occurs in a scene from the movie The Meg, where a large amount of bright white occupies most of the screen, preventing the TV from reaching higher brightness levels. However, this is not a significant issue, as the performance is still a considerable improvement over its predecessor.

Overall, these brightness levels, especially for an OLED panel not equipped with MLA technology, impress. Coupled with excellent coverage of the DCI-P3 colour spectrum, the Philips OLED 809 offers a truly spectacular HDR viewing experience.

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 in which we performed all our tests was "Filmmaker," which is quite standard in televisions from this manufacturer. However, let’s first examine its characteristics before the calibration process. The first aspect we will focus on is white balance, as it is critical to ensuring the image remains free from any colour cast. The chart clearly shows that in both SDR and HDR materials, two colours dominated significantly: red and green, resulting in a strong yellow tint that affected the entire image. This was particularly noticeable on the "ColourChecker" palette, where all colours shifted towards their warmer counterparts.

The second aspect we will assess is what we consider to be the two most important charts for evaluating picture quality: gamma and the Electro-Optical Transfer Function (EOTF) curve. Both aim to maintain appropriate brightness and contrast. The first chart, which describes the brightness levels in SDR materials, shows that the brightness was significantly lower than the reference value marked by the orange line. This resulted in a sharp increase in brightness and a notable decrease in contrast, which was inconsistent with typical OLED television behaviour. The EOTF curve, on the other hand, showed greater "moderation," subtly brightening the overall image only up to 50% of the maximum brightness.

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, like most leading manufacturers, has been providing advanced calibration tools for years. The inclusion of 2- and 20-point grayscale adjustments, along with an advanced CMS (Color Management System), has yielded extremely beneficial results and fundamentally improved the perceived image. Nearly every element previously mentioned has undergone a transformation and has been restored to its natural state. This is particularly noticeable in the "ColourChecker" palette, where the measured colour samples align harmoniously. Notably, the white balance has been excellently calibrated, ensuring a pure image free from unwanted tint in both SDR and HDR content. The previously problematic gamma has been well addressed, with only minor errors that do not impact the overall performance. Similarly, the EOTF curve has been refined, removing the subtle brightening effect, and now offers a truly reference-quality presentation.

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.

Philips OLED 809 struggled significantly in the smooth tonal transitions test. Focusing on the TV's algorithms, particularly the feature responsible for removing posterisation, the results were disappointing. This function, which offers several adjustable settings, proved ineffective in practice. The highest setting, while it does mitigate inconsistencies, it simultaneously blurs the entire image, rendering it virtually useless.

When dealing with lower-quality content, the performance of image upscaling algorithms becomes crucial. In this regard, the algorithms implemented in the OLED 809 perform admirably. They enhance image quality effectively, with minimal visible artefacts. Although slight edge fraying can occasionally be observed, it is unlikely to be noticeable during typical viewing sessions.

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 maximum refresh rate achievable on the Philips OLED 809 is 144 Hz, a feature that can be fully utilised when connected to a high-performance PC. However, when connected to consoles or used for standard television viewing, the refresh rate remains at typical values. For users seeking enhanced motion fluidity or wishing to eliminate the characteristic choppiness of films shot at 24 fps, Philips provides a sophisticated motion-smoothing system.

In the settings menu, there is a "Smoothness" slider designed to reduce choppiness, along with a "Motion Blur Reduction" option to enhance the sharpness of fast-moving elements. These features perform impressively and allow for granular adjustments, ensuring that each setting has a tangible impact on motion perception. Notably, the system operates effectively at a refresh rate of 120 Hz, taking advantage of multiples of video frame rates. With this comprehensive range of options, users can easily fine-tune the settings to suit their preferences. For example, slight smoothing without inducing the soap opera effect offers a balanced viewing experience.

Motion clarity on the OLED 809 is further bolstered by the exceptional response time of the OLED panel, measured at approximately 0.1 ms. This surpasses the performance of IPS/ADS or VA panels, making OLED technology unrivalled in this area.

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.

The Philips OLED 809 fully supports all technologies included in the HDMI 2.1 standard, and during testing, each activated without issue. This makes the TV an excellent choice for gamers, whether on console or PC. Notably, it features HGIG mode as a strong alternative to Dolby Vision, which is less ideal for gaming on this model due to its high input lag.

The TV also includes a dedicated GameBar for monitoring gameplay parameters and adjusting settings quickly. Features like a crosshair overlay for sniper shots, shadow enhancement for better visibility, and a colour filter for gamers with visual impairments further enhance its gaming appeal.

In summary, the OLED 809 is a fantastic choice for gaming, equipped with VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision gaming for a deeply immersive experience. The only drawback is the artificial sharpness in game mode, which cannot be fully softened, regardless of settings.

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.
