LG QNED86A / QNED85A / QNED87A vs TCL P89K / TCL P8K

Against the backdrop of contrast and black, the brightness of the QNED86A and the overall HDR effect performs much better. This is a television that can reach around 700 nits in the best conditions, so in terms of brightness alone, there is nothing to be ashamed of. As a result, scenes with strong lights, explosions, flashes, or bright parts of the landscape look clear and can make an impression. Interestingly, even in more challenging moments with small, contrasting elements on the screen, the television handles their backlighting well, and the details are quite visible. The problem resurfaces when there are a lot of dark tones. The lack of effective local dimming causes black to virtually disappear, and instead, we get a gray glow spreading across the entire screen. This kills the sense of depth and makes the image look flat, as if it lacks a cinematic quality. In bright animations or colorful family films, this won't be an issue because colors and bright light dominate there. But in horrors or productions set in darkness, these limitations are very palpable. As a consolation, it’s worth mentioning that the QNED86A is actually a QLED television with a PFS LED filter, which gives it very good coverage of wide color gamuts. Both the DCI-P3 palette and the wider BT.2020 perform really solid here. This ensures that colors in HDR films are saturated, vibrant, and have the right depth – even if the black itself disappoints, the colors can save the viewing experience and make the image look attractive.

The maximum brightness of the TCL P8K is around 300 nits, although in actual movie scenes, the TV maintains more around 250 nits. These values cannot be considered sufficient for achieving a full HDR effect – they are more akin to a solid base for SDR content. Therefore, we won’t see spectacular flashes, bursts of light, or moments when the screen truly “blinds” you, as is the case with more expensive models. The image is somewhat flattened, and the differences between light and shadow are more symbolic than realistic. Fortunately, TCL has a few aces up its sleeve that save the overall impression. One of them is the coverage of the DCI-P3 color gamut at around 93–94%. Thanks to an additional QLED layer (PFS LED), colors gain depth and intensity, clearly surpassing standard LCD panels. As a result, although the typical “wow effect” associated with HDR brightness is lacking here, the image can still impress with its saturation and vibrant tones, making movie scenes pulse with colors and avoiding a heavily faded appearance.

We primarily tested the QNED86A in Filmmaker mode, which is designed to provide the most accurate picture. Unfortunately, right out of the box, there were quite a few shortcomings. The most noticeable issue was the poorly adjusted white balance – there was a lack of blue, causing the overall image to lean slightly yellow, and at times, even orange. An even bigger problem turned out to be the way the television manages brightness. Due to its technical limitations – namely, local dimming that only works along the edges of the screen – the QNED86A tends to over-brighten entire scenes. This is where the flattening effect we mentioned earlier comes from. Instead of distinct depth and contrast, we get something akin to "boosted brightness," which can strain the eye over time.

In Filmmaker mode, the TCL P8K revealed certain imperfections in image reproduction from the start. We noticed that the television tends to slightly brighten scenes – its gamma was somewhat lowered, which made the image appear slightly "washed out," lacking depth, as if the contrast had slipped out of control. This was most evident in HDR content, where the EOTF brightness curve clearly deviated from the reference values. As a result, the darker parts of the image looked too gloomy, while the brighter sections didn't always reach the proper level of luminance. A second noticeable issue was a slight oversaturation of blue – the television stubbornly boosted this color, which caused some parts of the image, especially skin tones and reds, to have a slight purple tint. This is not a major flaw, but to a discerning eye – noticeable. Fortunately, most of these errors could be corrected during calibration. You can see the results of this adjustment in the graphs and photos below.

What was saved in the QNED86A6A is undoubtedly the colors. After calibration, the white balance was set with great precision, resulting in deviations on the Colour Checker palette mostly not exceeding the threshold of visibility for the human eye. In other words – the colors finally looked natural, without strange yellow or orange tones that previously ruined the experience. Unfortunately, even the best calibration cannot bypass design limitations. The already mentioned very modest number of local dimming zones and their unfortunate placement made the analysis of the EOTF curve in films still show clear over-brightening of scenes. The image tended to flatten, lacking cinematic depth. Fortunately, this effect is not as noticeable in older productions or SDR content. There, calibration really does its job and allows taming the QNED in such a way that the image can be pleasing. However, the specifics of this design – especially the contrast issues – cannot be entirely overcome.

After calibration, the TCL P8K showed a completely different face. It managed to achieve nearly perfect, even reference-level color reproduction in both SDR and HDR content. The screen no longer had a tendency towards a cool tint, and the white balance was perfectly balanced. The gamma values for SDR material also finally look as they should – the image has the proper depth and no longer appears washed out. The only remark that can still be made about the P8K concerns its "Chinese" traits, known from most TCL models. The TV still likes to manipulate saturation in HDR content in its own way – sometimes slightly boosting it, sometimes smoothing it out, which means the effect is not always fully predictable. Nevertheless, after calibration, the colors look stunning, and their accuracy is truly surprising. In most cases, measurement errors dropped below values of 1-2, which is a result that significantly more expensive models would not be ashamed of.

If someone is worried about possible "steps" when connecting colors, there is a simple way in the QNED86A. Just turn on the feature called Smooth Gradation and set it to medium level. Then the TV really smooths out all those unwanted transitions – especially in older productions – and does it in such a way that the film grain doesn't disappear, nor do strange artifacts appear. In other words, you can use it without worry.

The upscaling itself also turns out quite well. Of course, there are no miracles here – with lower quality sources, you can observe characteristic jaggedness. Fortunately, there is a sharpness slider in the menu, and if someone prefers a more "softer" image, it can be quickly adjusted to their taste.

The TCL P8K performs somewhat worse when it comes to the fluidity of tonal transitions in lower quality materials. The television does offer a feature to smooth out unwanted bands, but its effectiveness leaves much to be desired. Even at the highest setting, it’s hard to say there’s a real improvement – at times the effect is even the opposite of what was intended, as the feature can introduce small artifacts and unnatural blurriness on the screen.

On the other hand, upscaling, or scaling the image to 4K resolution, looks significantly better. The P8K handles this task surprisingly well – HD content, and even SD, is enhanced in an aesthetically pleasing manner without excessive loss of sharpness. There are indeed slight "hard" edges typical of this class of equipment, but this can easily be adjusted with the sharpness slider according to personal preferences. The final effect is more than satisfactory, especially considering the price range in which this model is located.

The QNED86A is equipped with a 120 Hz refresh rate panel, so right from the start, it's safe to say that it's suitable for both sports and gaming. And indeed, this is true – the image looks smooth, and motion blur is not very noticeable. IPS panels have always had some issues with this, and you can sometimes notice slight blurring here as well, especially in very dynamic scenes, but it's not something that ruins watching a match or a fast-paced game. For movie and sports fans, LG has added the traditional TruMotion smoother. In the menu, we have two sliders – one for movies (De-Judder), the other for sports (De-Blur). The first adds missing frames and allows you to adjust the character of motion – from raw, cinematic to more fluid, "theatrical." The second enhances sharpness during dynamic actions, so it's worth turning it up a bit if you're watching a lot of sports.

TCL P8K is one of the cheapest televisions offering a 144 Hz refresh rate, which in itself is already a significant advantage in this price segment. Thanks to the fast panel, this model can confidently be recommended to both sports fans and video gamers – the image is smooth, and movements of the ball or dynamic actions look natural. However, this does not mean that the P8K is only suitable for sports. On the contrary – it can maintain the right dynamics in movies as well, without introducing an artificial effect of "theatricality," as long as we set the parameters wisely. The television is equipped with a motion smoother called "Motion Clarity," which features two sliders: blur reduction and flicker reduction. The first is responsible for smoothing the image by generating additional frames, which increases fluidity but may cause a slight soap opera effect. The second, on the other hand, limits flicker and improves sharpness in motion, although it may slightly darken the screen. Appropriately adjusting these two parameters allows for a really good balance between natural movement and fluidity. The 60 Hz panel is good for dynamic content, although more demanding users will notice that it is not a top-tier display in terms of motion clarity.

In terms of gaming, the LG QNED86A6A is a complete tool. It features four HDMI 2.1 ports with full bandwidth of 48 Gb/s, which means that whether you connect a PlayStation 5, Xbox Series X, or a powerful PC – everything will work at full 4K 120 Hz with support for all features. This is a big plus, as some competitors still have only two such ports, which can be problematic with a larger number of devices. It also has VRR, or variable refresh rate, which eliminates screen tearing, and ALLM, which automatically activates game mode when the console is turned on. There’s also Dolby Vision Gaming and a proper implementation of the HGiG format, so titles supporting these formats look more vivid and detailed. Added to all of this is the Game Optimizer – a kind of control center for the gamer. From this level, you can view image parameters in real-time, quickly change modes, activate additional features, or adjust image settings to your preferences. The LG QNED86A6A essentially has everything one can expect from a modern gaming television.

Although the TCL P8K is a budget TV, it certainly can’t be said that it’s not suitable for gaming. On the contrary – this is a screen that can pleasantly surprise any gamer. It features two HDMI 2.1 ports, allowing us to easily output 4K at 120 Hz. For those gaming on PC, they will also appreciate the fact that the TV can even operate at 240 Hz refresh rate in lower resolution – a small thing, but it’s nice. In addition, there’s a full set of gaming-specific features: automatic game mode, Game Bar for quick parameter previews, VRR, HGiG, and support for Dolby Vision in games. All of this makes gaming on the P8K a truly enjoyable experience – the picture is smooth, the response is quick, and the TV communicates well with next-gen consoles. The TCL P8K shows that a cheap screen doesn’t have to mean giving up fun. Definitely not when it comes to gaming.
