TCL P89K / TCL P8K vs Sony BRAVIA 2 II (S25M2)

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.

Sony Bravia 2 II is not a very bright TV and unfortunately that is immediately apparent in HDR. In our measurements brightness stayed around 300 to 330 nits, which is definitely too low for the brightest parts of the picture to look truly impressive. In practice HDR here does not differ that much from ordinary SDR. Bright highlights, the sun, or lamps are of course visible, but they lack the intensity you would expect from HDR material. The Bravia 2 II therefore performs much better with regular SDR content, and it is in that use case that its limited brightness will be least noticeable.

Color gamut coverage

Sony Bravia 2 II also doesn't impress when it comes to colors. The TV doesn't use any additional gamut-expanding filter, such as the quantum dots found in QLED TVs or a PFS phosphor layer. In our measurements DCI-P3 coverage was about 78%, and the very wide BT.2020 around 57%. That's definitely too little to talk about truly saturated colors in HDR content. More intense reds, greens, or turquoise hues will simply be less striking than on TVs with an expanded color gamut. The Bravia 2 II therefore fares much better with standard Rec.709, the gamut used for movies, series, and TV in SDR.

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.

Out-of-the-box color reproduction in Cinema mode was really good, at least for ordinary SDR material. The Bravia 2 II had a slight tendency to boost reds, so some colors skewed a bit warmer, at times with a faint pinkish tint. However, it wasn't a major fault, and during normal viewing the picture still looked quite natural. There was a bit more going on with image brightness. Looking at the gamma trace, you can see Sony doesn't stick exactly to the reference value. The darkest parts are slightly lifted, while as brightness increases the gamma gradually rises and a larger portion of the image becomes darker than it should. That said, the difference isn't large enough to seriously interfere with everyday viewing. Overall, SDR straight out of the box performs pretty well.

The situation is much worse in HDR. We already mentioned the limited color gamut, but the Bravia 2 II also manipulates image brightness quite aggressively here. The EOTF curve sits below the reference for a large part of the range, which means the TV renders most midtones and brighter parts of the scene darker than the source material intends. Only toward the very end of the range does the curve flatten out, as the panel reaches the limits of its capabilities. Combined with a peak brightness of around 300 nits, this results in HDR that not only lacks punch but can simply look too dim.

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.

Calibration did a lot for the Bravia 2 II, especially with SDR content. Above all, we were able to even out the white balance and tidy up the gamma, which now sticks much closer to reference values. As a result, the picture no longer has the previous pink tint, and the brightness of individual areas is much better balanced. You can also see this in the color errors, which dropped to a very low level after calibration (with minor issues in the most saturated reds).

We also partially tamed the Bravia 2 II in HDR, particularly in how the TV manages image brightness. However, there is one thing no calibration can fix: the panel's inherent limitations. The narrow color gamut means the TV physically cannot reproduce the most saturated colors present in HDR content. On top of that, the IPS panel's low contrast leaves darker scenes veiled by a grayish glow, causing colors to lose some of their depth. So we can improve how the Bravia 2 II uses its capabilities, but unfortunately we can't overcome the panel's fundamental limits.

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.

Upscaling in the Bravia 2 II performs quite well, and in that respect the TV maintains the standard Sony has accustomed us to. Lower-resolution content is sensibly scaled to 4K, with the image slightly smoothed and without over-sharpening edges. It’s a different story when it comes to improving content with visible compression. That’s handled by the "Digital Noise Reduction" feature, which on the "High" setting can indeed smooth out some ugly tonal banding. The problem is it does so fairly aggressively, removing a lot of fine detail along with the imperfections, including natural film grain. Moreover, when there’s more motion on screen its effectiveness drops significantly and the improvement becomes minimal. So we generally avoided using this feature in everyday viewing.

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.

The Bravia 2 II uses a 60 Hz panel and, given its capabilities, handles motion quite well. However, keep in mind this is a basic panel, and its limitations are already noticeable, especially with sports. The TV cannot interpolate 50/60 fps content to a higher refresh rate, so it can't further improve the sharpness of fast-moving objects. For movies and series, you get a standard motion smoother that can reduce the characteristic judder of material shot at 24 fps.

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.

The Bravia 2 II is not a TV particularly well suited for gaming, and the feature list makes that clear pretty quickly. You basically only get automatic low-latency mode (ALLM) and a simple Game Bar where you can view basic signal information and change a few settings. But that's where the list of advantages ends. The TV doesn't support VRR or 120 Hz (not even at lower resolutions), and on top of that it has problems with a proper implementation of the HDR HGIG format. It can, of course, be used for occasional console gaming, and thanks to low input lag controls stay responsive, but if you're mainly looking for a TV for gaming, the Bravia 2 II will simply be a very limited choice.
