Philips OLED820 vs LG QNED80A6A (VA)

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 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 immense precision, as this is the brightness range in which contemporary productions are mastered. Of course, there are situations where even the OLED820 has to compromise. Full-screen scenes filled with white, like those in the film The Meg, can drop brightness to 400–500 nits, which clearly weakens the effect. This is a characteristic of OLED technology that has yet to be fully eliminated. Despite this limitation, it is hard not to appreciate the HDR in this model – high luminance and a wide DCI-P3 colour gamut coverage of 99% make the image simply look fantastic.

Let's now talk about how this television shines. If you are expecting dazzling light effects, we need to temper your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. This is not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamism" offered by flagship products. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another crucial category: colours. This is where PFS technology comes into play, which LG marketers disguise under the name QNED/NanoCell. Thanks to this approach, the television offers a much wider colour palette than classic LCD designs. In our tests, coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even with lower brightness, when watching movies in HDR, colours will be vivid, deep, and appropriately saturated. The image is not washed out but rather juicy, which is a significant advantage in this price range.

The colour reproduction in the factory settings really surprised us, and positively so. 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, though there was a slight deficiency in the blue hue, which occasionally gave the image a slightly yellowish tint. However, this is not a flaw that particularly detracts from everyday viewing. A bigger issue arose with the brightness characteristics. The gamma curve clearly deviated from the ideal, with the line 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.

It might seem that since the QNED80A is one model, regardless of the version, it should offer the same picture. 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 television, “out of the box,” serves us a picture with a clear dominance of red and a deficiency of blue. Overall, it is very warm, even hot. Many users may describe this as a picture that is “too cinematic,” leaning towards sepia. Additionally, there is the issue of the gamma curve – the television has a tendency to slightly artificially brighten scenes (gamma is too low), causing the picture to lose some depth. The good news is that these are not panel errors, but merely software issues. As always in our tests, we conducted professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

After calibration, both the Filmmaker mode and the gaming mode gained a lot. A slight adjustment of the white balance and an improvement in brightness characteristics produced excellent results in SDR content – the image looked almost perfect, natural, and very close to reference. In the case of HDR materials, the situation was similar, the colours were presented wonderfully, and it was hard to find anything to criticise. However, we noticed a certain feature, which we already pointed out when comparing scenes from the film Billy Lynn. The analysis of the EOTF curve showed that the television has a slight tendency to dim details in the blacks, so the darkest parts are not always displayed exactly as intended by the director. Nevertheless, the effect after calibration is stunning, and the OLED820 is emerging as one of the more interesting screens in its class. It just needs a little pampering, and there really is nothing to worry about.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initial, too warm white balance and, most importantly, correct the gamma curve. The television stopped artificially brightening scenes, which gave the image depth. The greatest improvement is noticeable in SDR content, that is, while watching regular television, YouTube, or playing games without HDR. Here the QNED80A shows its class – colour reproduction errors (DeltaE) have dropped below a value of 2. In technical terms, this means that the errors are virtually unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Although we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the television still "interprets" the image in its own way. This stems from the nature of the edge-lit backlight with local dimming and the fact that LG gives the calibrator very little control over this parameter. In short: the television struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is significantly more accurate and pleasant to behold than with factory settings, even if it falls a bit short of studio perfection.

Fortunately, the earlier effects of the mentioned posterisation can be quite effectively mitigated. The "distortion reduction" function set to a medium level deals with unwanted colour banding, improving the smoothness of tonal transitions. It does happen that it works a bit too aggressively and also smooths out some details – such as minor skin imperfections of the actors – but nevertheless, it can be considered worth using without substantial compromises. The upscaling in the OLED820 also performs quite well. The test image with the model is exceptionally soft, sometimes even too much so, although this can be rectified by slightly boosting the sharpness in the picture menu – this is really a matter of individual preference. The absence of overscan issues with very low-resolution content is also commendable, meaning we don't have to worry that the image will be unnecessarily cropped.

In this category, the QNED80A proves to be a true "dark horse." It is an excellent, affordable television for those who frequently watch lower-quality content – for example, traditional cable TV. The processor used here handles upscaling, that is, enhancing low resolution to native 4K, exceptionally well. 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 content. This feature works really effectively, eliminating annoying "banding" of colours under heavy video compression. 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 artefacts or distortions. Nonetheless, it is definitely worth giving this feature a chance, as in most cases the quality improvement is visibly apparent.

The fluidity of motion 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 primarily benefits PC gamers, but even with standard television sources or consoles, where it operates at 120 Hz, the motion is fast, sharp and simultaneously smooth, without signs of blurring. This is thanks to the remarkable response time between pixels, which maintains image clarity in every dynamic scene. The manufacturer has also added its own smoother called "Motion Style". In the menu, we find two sliders – the first, responsible for fluidity, allows adjustments to the number of artificially added frames in films. This way, we can choose a raw, cinematic character with a distinctly visible film frame 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.

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 television is equipped with a panel featuring a native refresh rate of 60Hz. There is no denying it – at this price, we expected more as we know that Chinese manufacturers can offer 120Hz screens for a similar price. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strongest aspect of this display. Fortunately, LG has equipped the television with a proven motion smoothing system called TruMotion. It works quite effectively 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: the motion becomes smoother, yet still looks natural, without the artificial "television theatre" effect.

The Philips OLED820 is one of the most complete televisions for gamers. On board, we find practically everything one could expect: two HDMI 2.1 ports with full bandwidth of 48 Gbps (it's a shame there aren't four), variable refresh rate VRR, automatic game mode ALLM, support for Dolby Vision in games, and a good implementation of the HGiG mode. The television handles lower resolutions at 120 Hz with ease, so one can count on considerable flexibility when choosing different picture modes on the console. Philips also includes a Game Bar – a panel that allows changing picture modes, adding a crosshair, or previewing parameters. Although it looks rather clunky and is less polished than that of the competition, it does its job. In practice, therefore, the OLED820, in addition to a full set of four HDMI 2.1 ports, offers nearly everything a gamer could need.

Now that we have established that the QNED80A is a television with a 60Hz panel, we must say it plainly: we will not be playing here at 120 frames per second at any resolution. Does this disqualify the equipment in the eyes of gamers? Not necessarily, especially those "casual" ones. LG has decided to sweeten this technical limitation by packing quite a few useful functions inside. We have support for VRR (variable refresh rate) in the range of 48-60Hz and automatic game mode ALLM, which instantly reduces input lag upon detection of a console. All of this is managed from a very convenient, purple Game Optimizer menu, which has already become LG's hallmark. A big plus goes to the manufacturer 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, playing in HDR is clear, and the details in shadows and highlights are accurately reproduced, rather than "cut off".
