Philips OLED820 vs LG NANO81A / NANO80A

When it comes to HDR quality, the Philips OLED820 uses the same class of WOLED panel found in its biggest rivals – the LG C5 and the Samsung S90F. This means we can expect really solid results. This year, mid-range OLED panels can exceed the threshold of a thousand nits, and the tested model reaches around 1300 nits in some films. This is an outstanding result, allowing the director's vision to be conveyed with incredible precision, as this is the brightness range in which modern productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes flooded with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly diminishes the effect. This is a characteristic of OLED technology that has not yet been fully eliminated. Despite this limitation, it's hard not to appreciate the HDR in this model – high luminance and a wide coverage of the DCI-P3 colour palette at 99% make the image look simply fantastic.

If you're hoping that HDR on the NANO81A will bring tears to your eyes, I have to disappoint you. This TV is just too dark to show what this format is really about. With a brightness of only 250 nits, HDR really only exists on paper here. In practice, during viewing, it's very hard to tell whether we're watching material in high dynamic range or regular SDR – it simply lacks that “punch” of light in the bright parts of the image. But, to balance out the criticism, we do have one light at the end of the tunnel – and quite a distinct one at that. It's about colour 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%. That's a really solid result, placing this model significantly above typical budget models based on regular white LEDs without any filters. Of course, it still lags a bit behind QLED TVs or advanced panels with PFS filters, but for this price range, the colours 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 colour reproduction in the factory settings really surprised us, and in a positive way. The Philips OLED820, switched to Filmmaker mode, immediately showed that it was quite well tuned in terms of colour. The white balance was relatively accurate, although there was a slight deficiency in the blue hue, which sometimes gave the image a slightly yellowish tint. However, this is not a drawback that particularly interferes with everyday viewing. A bigger problem arose with the brightness characteristics. The gamma chart clearly deviated from the ideal, as the line was below the expected values, causing the image to be excessively brightened, and the colours looked as if they were covered with a light milky filter. This effect was also noticeable in tests using the Colour Checker pattern, where more pronounced errors appeared.

For every film fan, the natural choice in LG televisions is the Filmmaker Mode. It is designed to show the image as the director intended – without unnecessary "enhancements". Unfortunately, in the case of our test unit NANO81A, the factory settings left a bit to be desired. The main issue turned out to be the white balance. Measurements revealed a distinct deficiency of blue, which in practice meant that many scenes had a slightly yellowish, even "yellowed" tint. The white wasn’t perfectly clean, which took away the freshness of the image. Additionally, the brightness management wasn't perfect either – the factory-set gamma was too low. The image often appeared oversaturated, as if it had been pulled too much from the shadows, which detracted from its naturalness and depth. Fortunately, LG, even in this relatively low price range, does not block access to advanced settings. The calibration options for this model are extensive, which is a significant plus for those who enjoy "fiddling" in the menu. We decided to approach the matter our way and see how much we could squeeze out of this panel with professional calibration.

After calibration, both the Filmmaker mode and the gaming mode improved quite a bit. A slight adjustment of the white balance and enhancement of the brightness characteristics yielded excellent results with SDR content – the image looked nearly perfect, natural, and very close to the reference. For HDR material, the situation was similar; the colours looked fantastic, and it was hard to find fault with anything. However, we did notice a certain characteristic, which we had already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the TV has a slight tendency to dim details in the blacks, meaning that the darkest parts are not always displayed exactly as the director intended. Nevertheless, the effect after calibration is superb, and the OLED820 is emerging as one of the more interesting screens in its class. A little bit of fine-tuning is all that’s needed, and there’s really nothing to worry about.

After calibration, the NANO81A is a completely different television. What LG offers in terms of image enhancement tools, even in such an affordable model, deserves major credit. We were able to completely eliminate that annoying yellowing of whites and make the colours natural, vibrant, and simply "real". In SDR content (i.e., regular television, YouTube, or older films), the picture now looks miles better – it’s clean, well-balanced, and no longer strains the eyes with strange hues. It’s clear that this panel has significant potential, which is simply wasted out of the box due to poor presets. However, we have one serious reservation that calibration cannot fully overcome – it's about brightness management in HDR mode. The LG algorithm in this model is very conservative. The TV deliberately dims the HDR image to avoid clipping the already weak blacks of the IPS panel. The developers faced a choice: either provide more light and accept that black would become light grey, or dial down the brightness to maintain any contrast. They chose the latter. Despite this, after our adjustments, watching anything on the NANO81 is considerably better.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" feature set to medium handles unwanted colour banding well, improving the smoothness of tonal transitions. It does sometimes work a bit too aggressively and smooths out some details – such as the minor imperfections of the actors’ skin – but despite that, it can be considered worth using without major compromises. The upscaling in the OLED820 also performs well. The test image with the model is exceptionally soft, sometimes perhaps too much, although this can be remedied with a slight increase in sharpness in the picture menu – that's a matter of individual preference. The absence of overscan issues with very low-resolution content is also commendable, allowing us to not worry about the image being unnecessarily cropped.

It often happens that cheap 4K panels ruthlessly expose all the "dirty laundry" and imperfections in lower resolution materials. However, with the LG NANO81A, the situation is completely different. It's a really solid performer when it comes to handling content that's 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, which you can find in the settings. It is exceptionally effective in combating colour banding, which is a godsend when watching low bitrate materials, such as from some streaming services or older files from the web. However, it is worth maintaining a certain vigilance. Since we are dealing with a less powerful chip than in LG's top models, too aggressive a setting for this option can sometimes result in minor artifacts or 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.

Motion fluidity is an area where OLEDs always shine, and the Philips OLED820 confirms this rule. The panel itself offers a refresh rate of 144 Hz, which will mainly benefit PC gamers, but even with standard TV sources or consoles, where it operates at 120 Hz, motion is fast, sharp, and simultaneously smooth, without any signs of smearing. This is thanks to the remarkable response time between pixels, which ensures the image maintains clarity in every dynamic scene. The manufacturer has also added their own smoothness enhancer called "Motion Style." In the menu, we find two sliders – the first, responsible for smoothness, allows for the adjustment of the number of artificially added frames in films. This way, we can choose a raw, cinematic character with clearly visible film frames or a more theatrical image with smooth motion. The second slider is for motion blur reduction, particularly useful in sports broadcasts. Here, we definitely recommend setting it to the maximum value, as the effect is truly excellent.

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

The Philips OLED820 is one of the most comprehensive TVs for gamers. Onboard, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (shame there aren't four), Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), support for Dolby Vision in games, and a good implementation of the HGiG mode. The TV also handles lower resolutions at 120 Hz without issue, so you can count on great flexibility when choosing different picture modes on your console. Philips also adds a Game Bar – a panel that allows you to change picture modes, add a crosshair, or preview parameters. Although it looks a bit clunky and is less refined than its competitors, it gets the job done. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 connections, offers almost everything a gamer could need.

NANO81A is unfortunately not a device designed with esports in mind. The lack of 120 Hz signal support is a fact that users planning to purchase this model simply have to accept. Nevertheless, LG’s engineers have worked hard to squeeze the maximum potential from this 60 Hz panel, offering a set of features that genuinely improve gaming comfort. First and foremost, the television supports VRR technology (in the range of 48–60 Hz) and ALLM. This ensures that 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 a console. Managing these settings is extremely simple thanks to a dedicated system overlay that allows for a quick preview of parameters without leaving the game. A very significant advantage is support for the HGiG format. This solution is crucial for owners of modern consoles, as it allows the television 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 is unfortunately a common issue in budget LCD televisions.
