TCL P89K / TCL P8K vs Hisense UR8S

The maximum brightness of the TCL P8K is around 300 nits, although in real film scenes, the television maintains more of a level of about 250 nits. These values cannot be considered sufficient to achieve a full HDR effect – they are closer to a solid base for SDR content. Therefore, we will not see spectacular flashes, bursts of light, or moments in which the screen actually "blinds," as is the case with more expensive models. This makes the image somewhat flat, 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 reception. One of these is the coverage of the DCI-P3 colour palette at around 93–94%. Thanks to an additional QLED layer (PFS LED), the colours gain depth and intensity, clearly surpassing standard LCD panels. As a result, although there is a lack of the typical "wow effect" associated with HDR brightness, the image itself can impress with its saturation and vibrant tones, making film scenes pulse with colours and not appear strongly washed out.

UR8S is a slightly higher-end Mini-LED, so you could expect a lot in terms of brightness. And indeed, on a synthetic test pattern peak brightness reached around 2200 nits. That’s a very good result, but as always what’s much more important is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes, where there’s a lot of light on screen, the UR8S can deliver really strong HDR. Brightness then reaches about 1500 nits, so the image is very intense and has plenty of punch. It’s worse with small bright elements on a dark background. The TV clearly dims them to keep good blacks and to prevent excessive bloom. As a result things like single stars or tiny reflections can be only around 200 nits. And here HDR is no longer as impressive. So you can see that the local dimming algorithm works effectively, but it also has its cost: sometimes it simply sacrifices the brightness of small details in favour of contrast.

Colours

With RGB Mini-LED TVs colours should be judged a little differently than usual. If we look solely at the panel’s native capabilities, the UR8S performs excellently. We measured around 94% coverage of BT.2020 and practically full DCI-P3. These are among the highest values currently found in LCD TVs and this is where the potential of the RGB backlight is most obvious. The problem is that this potential is not always realised in real scenes. When we ran the same measurements on test patterns with a film background applied, saturation of some colours began to fall noticeably. Individual zones are not always able to control the three RGB components so precisely when the scene becomes more complex. This is most visible with blue and magenta. On simple test patterns they can look very strong, but in more demanding scenes samples of those colours visibly shrink. So the UR8S’s capabilities are enormous, it’s just that the TV cannot fully make use of them in every scene.

In Filmmaker mode, the TCL P8K revealed certain imperfections in image reproduction from the outset. We noticed that the television had a tendency to slightly brighten scenes – its gamma was somewhat low, causing the image to 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 graph clearly deviated from reference values. As a result, darker areas of the image appeared too gloomy, while brighter areas did not always reach the correct level of luminance. Another noticeable issue was a slight overemphasis on blue – the television stubbornly boosted this colour, causing certain parts of the image, especially skin tones and reds, to have a subtle purple tint. This is not a major flaw, but it is noticeable to a trained eye. Fortunately, most of these errors could be corrected during calibration. You can see the results of this adjustment in the graphs and photos below.

For assessing the out-of-the-box colours we used Filmmaker mode, which is intended to show an image that is as close as possible to how the material was prepared. Looking at the white balance alone, the UR8S performs quite well. There is no strong tint that immediately jumps out, although as brightness increases a little too much blue and red start to appear, with a simultaneous shortfall of green. Colour errors therefore show up in measurements, but the image itself does not look bad. We have far greater reservations about how the UR8S manages picture brightness. In SDR the gamma sits around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the picture is too bright, especially in the midtones. Shadows are lifted too much, causing the image to lose some depth. A similar tendency is visible in HDR. The EOTF curve is above the reference value for a large part of its range, so the UR8S again brightens the image more than it should. This is not due to a lack of brightness — the TV has plenty — but to the way it manages that brightness. As a result, HDR content can look very striking, but not always precisely as it should.

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.

Hisense provides plenty of calibration options and, in SDR, these can yield a very good result. After calibration, the white balance is practically even across the entire range, and colour errors fall to very low values. The UR8S can be adjusted very precisely here. HDR is somewhat different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations begin to appear. The most interesting aspect, however, is the behaviour of the EOTF curve. Even after it has been correctly set on test patterns, the UR8S still tends to interpret brightness in its own way when watching films. Depending on the scene, parts of the image are slightly brightened while others are dimmed relative to how they should appear. This shows that the algorithms controlling the local dimming have a significant influence on the final image. Calibration therefore allows colours to be improved very effectively, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

The TCL P8K performs somewhat worse when it comes to the fluidity of tonal transitions in lower-quality materials. The television does offer a function to smooth out unwanted bands; however, its effectiveness leaves much to be desired. Even at the highest setting, it's hard to talk about any real improvement – at times the effect is almost the opposite of what is intended, as the function can introduce small artifacts and unnatural blurring on the screen.

On the other hand, upscaling – that is, 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. While there are slight "hard" edges typical of this class of equipment, this can be easily adjusted with the sharpness slider to suit personal preferences. The final effect is more than satisfactory, especially considering the price range in which this model is situated.

A big plus of the UR8S is the use of the MediaTek Pentonic 800 processor, and digital image processing is one of this model's stronger points. The TV handles smoothing tonal transitions very well, especially with lower-quality content. The feature responsible for this effect works effectively without overprocessing the picture. Even on the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image is not overly sharpened. The UR8S simply copes very well with a weaker signal, and in this respect it is one of its most notable strengths.

TCL P8K is one of the cheapest televisions offering a refresh rate of 144 Hz, which in itself is quite an 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 the movement of the ball or dynamic actions look natural. However, this does not mean that the P8K is suitable solely for sports. On the contrary – it can also maintain appropriate dynamics in films without introducing the 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 judder 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 latter, on the other hand, reduces judder and improves sharpness during movement, although it can slightly darken the screen. Properly adjusting these two parameters allows for a really good balance between natural motion and fluidity. It has a 60 Hz refresh rate, but it is hard to say that it is a top-tier panel in terms of response speed. It will perform well for dynamic content, although more demanding users will notice that it is not a screen from the highest class in terms of motion clarity.

The UR8S is equipped with a panel with a native 180 Hz refresh rate, so right from the start it offers excellent motion handling. The panel itself performs really well here, although some limitations typical of VA panels are still visible. Motion blur is relatively minor for this type of screen, but with faster motion (especially on darker backgrounds) it can still be noticed, particularly when compared with the same image on OLED TVs.

Although the TCL P8K is a budget television, it cannot be said that it is unsuitable for gaming. On the contrary – it is a screen that can pleasantly surprise any gamer. It features two HDMI 2.1 ports, allowing for 4K output at 120 Hz without any issues. For those gaming on a PC, they will also be pleased to know that the television can operate with a refresh rate of up to 240 Hz at a lower resolution – a small thing, but it delights. Additionally, it comes with a full set of gaming features: automatic game mode, Game Bar with 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 television communicates well with next-generation consoles. The TCL P8K shows that a cheap screen doesn't have to mean giving up on fun. Certainly not in terms of gaming.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you can expect from a modern console or PC display. It offers ALLM, VRR and 4K at 120 Hz. There is also Dolby Vision in Game Mode, so when using, for example, the Xbox Series X you do not have to give up that HDR format. PC gamers get even more options. The panel can run at 4K at 180 Hz, and dropping to Full HD can raise the refresh rate to as much as 330 Hz. There is also a Game Bar that lets you quickly check key information and change gaming-related settings. The only clear omission is a correct implementation of HGiG. With it enabled the TV still alters HDR brightness mapping, so we do not get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
