TCL P89K / TCL P8K vs LG QNED80A6A (VA)

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.

Let's talk now about how this TV shines. If you expect dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. That's not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamic range" that flagship products offer. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another key category: colors. Here, the PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. Thanks to this process, the TV offers a significantly wider color palette than classic LCD designs. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even at lower brightness, when watching movies in HDR, the colors will be vivid, deep, and properly saturated. The image is not washed out but lush, which is a significant advantage in this price range.

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.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. 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 TV “out of the box” serves us a picture with a clear dominance of red and a deficiency of blue. The overall image is very warm, almost hot. Many users might describe this as a “too cinematic” image, approaching sepia. Additionally, there's the issue of the gamma curve – the TV tends to slightly, artificially brighten scenes (the gamma is too low), causing the picture to lose some of its plasticity. The good news is that these are not flaws of the panel, but merely of the software. As always in our tests, we carried out a professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

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.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initially too warm white balance and, most importantly, correct the gamma curve. The TV stopped artificially brightening scenes, which added depth to the image. The biggest improvement is visible in SDR content, meaning when watching regular television, YouTube, or in games without HDR. Here, the QNED80A shows its class – color reproduction errors (DeltaE) dropped below a value of 2. In technical terms, this means that the errors are practically unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Even though we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the TV still "interprets" the image in its own way. This is due to the nature of the edge-lit local dimming used and the fact that LG gives the calibrator a very limited range of control over this parameter. In short: the TV struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is much more accurate and pleasant to the eye than in factory settings, even if it still falls short of studio ideal.

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.

In this category, the QNED80A proves to be a real "dark horse." It's a fantastic, affordable television for those who often watch lower quality materials – for example, from traditional cable TV. The processor used here handles upscaling exceptionally well, meaning it enhances low resolution to native 4K. 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 material. This feature works really effectively, eliminating the annoying "banding" of colors in heavily compressed video. 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 artifacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, as in most cases, the improvement in quality is noticeable to the naked eye.

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.

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 TV is equipped with a panel that has a native refresh rate of 60Hz. There's no point in hiding it – at this price, we expected more because we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strong suit of this screen. Fortunately, LG has equipped the TV with a proven smoothing system called TruMotion. It works quite well 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: motion becomes smoother while still looking natural, without the artificial "TV theater" effect.

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.

Since we have established that the QNED80A is a 60Hz panel television, we must say it directly: we will not be playing here at 120 frames per second in any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for "casual" gamers. LG has decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) ranging from 48-60Hz and an automatic game mode ALLM, which quickly reduces input lag upon detecting a console. We manage all of this through a very convenient, purple Game Optimizer menu (Player Panel), which has already become LG's trademark. The manufacturer deserves big credit 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, HDR gaming is clear, and details in shadows and highlights are accurately reproduced, rather than "cut off."
