Sharp GP7 vs TCL P89K / TCL P8K

In terms of HDR, the Sharp GP7 can pleasantly surprise us. The maximum brightness around 500 nits is the threshold at which the real advantages of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer distinction of elements in both bright and slightly darker scenes. Additionally, there is a DCI-P3 color gamut coverage of around 95%, which allows for vibrant, visually pleasing colors. Of course, this is not the highest league, but for this price range – a big plus.

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.

Upon taking it out of the box, in movie mode, the GP7 doesn’t perform badly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a slightly greenish tint. This is visible, for example, on the faces of characters, which become less three-dimensional. The gamma is somewhat brightened in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone additionally emerges, making colors appear less natural. On the other hand, looking from the "out of the box" perspective, these settings are not bad – just minor adjustments are needed, and we will try to improve them with special tools.

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.

Calibration really makes a difference in GP7. After implementing the adjustments, we achieved a better white balance in HD content, and the colors started to look much more natural, with minimal deviations and without a clear dominance of individual colors. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there is still a visible issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our maneuvering room, but nonetheless, this is a significant step forward compared to the factory settings.

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.

The TV can quite well scale lower quality content. Our test panels were well reproduced, and although there was minimal aliasing on small, delicate shapes (for example, thin branches), it still looked satisfactory. Additionally, the GP7 offers a "10-bit color reproduction" feature to smooth out tonal transitions in poor quality materials. It is useful, but at the expense of some details, which is why we recommend turning it on only when we are really watching something of poor quality.

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.

With a 60 Hz refresh rate and an average response time, it's hard to expect miraculous smoothness. In dynamic tests, like the one with the "little green man," it is evident that the image can blur and occasionally lose sharpness. For watching movies and series, this is acceptable, especially since one can use a motion smoother with three levels of adjustment. However, if we care about ultra-smooth sports broadcasts or super responsive gaming, we may feel underwhelmed.

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.

Let's not kid ourselves – the GP7 is not a television for the most demanding console gamers. Yes, it has ALLM that will automatically switch the TV to low latency mode, but it lacks VRR or G-Sync. There is also no advanced menu to facilitate the adjustment of settings during gameplay. Dolby Vision in games? Yes, but with such high input lag that it's hard to talk about comfort. If we play occasionally and do not aim for the highest standards, we can get by, but fans of technical innovations will be disappointed.

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.
