Panasonic Z95B vs TCL C8L / QM8L

The quality of HDR in the Panasonic Z95B belongs to the absolute elite. Thanks to the latest generation panel, named by the manufacturer Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in movie scenes. The effect is impressive and can amaze with the intensity of light, giving a sense of contact with the screen that goes beyond previous experiences. Similar sensations accompanied us only during tests of the LG G5, Samsung S95F, or Philips OLED910. Of course, there are moments when the device's algorithms decide to limit luminance – this especially applies to full-screen bright sequences, such as the closing credits in the movie The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still a result that makes a huge impression. One can say that HDR in this model has been brought to a masterful form. A significant step forward is also visible in the reproduction of the color palette. The new tandem OLED panel does not yet match the best QD-OLED screens in terms of full gamut coverage, but the gap between these solutions has significantly narrowed. When watching movies, the differences are subtle enough that it's hard to notice them under normal conditions, and the colors remain vivid and saturated.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – and I mean literally. On a synthetic chart of 5%, our measuring equipment indicated a result exceeding 4500 nits. This is a result that is downright cosmic, considering that reference director monitors, which we often refer to in our materials, typically operate around 4000 nits. Does this mean that the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not exactly. Dry synthetic tests are one thing, and real movie images are another. In real, varied scenes, the C8L achieves a peak of around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but also clearly lower than what the manufacturer boasts in the specifications. The trouble starts with very small flashes of light – then brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep black and minimize halo effect, but it does so at the expense of HDR impact. This is perfect evidence that laboratory charts rarely correspond to what we ultimately see on the screen.

Huge applause is due for color reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the true jaw-dropper is the measurement of the extremely demanding BT.2020 space. The C8L achieves as much as 90% in it, placing it alongside today's top screens that boast RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene displayed. Of course, one must remember that content mastered for such a wide gamut in films or series is still a rarity. However, the mere fact that the panel has such a "color reserve" deserves immense admiration.

The factory color reproduction in Filmmaker mode, my friends, is a true phenomenon in the case of the Panasonic Z95B. I'm talking about our test unit, but the result was so good that it's hard to believe. The only detail to nitpick is a slight lack of blue in the white balance, but other than that, the television, right out of the box, displayed an image like we've never seen in factory mode. Color palette tests, Color Checker – everything pointed to values below Delta 2. This is a much lower result than the threshold of human eye perception, which means, quite frankly, that the viewer stands no chance of noticing serious deviations. It looks as if Panasonic really calibrated this model at the factory stage. Of course, we cannot rule out that we got an exceptionally well-set unit, but the result is still impressive. We are very strict in our assessments of factory calibration, and here our jaws simply dropped.

We tested the TCL C8L in the best factory picture mode available in this TV’s menu for image fidelity. That, of course, is Filmmaker Mode, which appeared in this brand’s software relatively recently (a year ago in the "K" series). Thanks to it, an average user can get a pretty good color reproduction straight out of the box, although it is certainly not a perfectly tuned mode. Looking at the factory white balance of our unit, both in SDR and HDR material, the red component was clearly lacking, which made the image noticeably cooler and caused a slight shift toward bluish-green tints. The issue of brightness management is also ambiguous, as we mentioned earlier. While for SDR content the gamma linearity is actually correct and holds steadily at the reference value of 2.4, in HDR things look much worse. Tracking the EOTF curve clearly shows the TV has a significantly boosted brightness across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that in a mode that by definition should avoid that. Of course, like every sample in our lab, this one also underwent professional calibration, and its results are shown below.

The color reproduction after calibration in the Z95B is a topic that is difficult to elaborate on for long because there simply wasn't much to be done here. A slight adjustment of the white balance was enough to eliminate the lack of blue, and at that moment the picture jumped to an almost reference level. I must admit that we haven't had such a small scope of work in a long time. If any of you are particularly observant, you might notice minimal deviations in the EOTF curve, but this is more related to the operation of the dynamic tone mapping function that we mentioned earlier. Really, this is not a flaw, but rather a feature of this solution, which intentionally changes the brightness characteristic depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that already looks great right out of the box, and after calibration, it reaches a level where it is really hard for us to find anything to improve.

As you can see, the results of a professional calibration of the TCL C8L are really promising, thanks to the extensive adjustment tools the manufacturer put at our disposal in the menu. Above all, we were able to completely correct the white balance — we eliminated the red deficiency, so the image finally stopped drifting toward unwanted cool tones. After that adjustment, errors in the ColorChecker test fell to near-reference levels, regularly landing below a Delta E of 2, which is below the threshold of human perception.

If the test patterns look this perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with actual movie material (I recommend enabling the EOTF filter when watching movies), you can see that in most scenarios the TV still reacts to HDR metadata its own way. As a result, the picture can be slightly over-brightened and not faithful to the creators' intent, and it was precisely this lack of consistency with real films that cost the C8L a few points.

Let's start with what works well. The upscaling in the Z95B is at a very high level – the picture in lower resolutions is clear and sharp, with only minor drawbacks being slight aliasing in some areas of the image. It's also important that the television does not crop the material in any way and maintains its aspect ratio, which is not always an obvious fact even in 2025.

The situation is worse when it comes to digital processing. Features such as "gradation smoothing" or "block noise reduction" practically do not work – the tested material looked identical regardless of the settings. We might as well point out that this function simply doesn't exist. This is somewhat disappointing, especially since Panasonic strongly promotes its HCX Pro AI II processor, boasting of the presence of artificial intelligence that improves picture quality. Meanwhile, in such a basic matter, the television does not deliver a real effect and looks worse than one might expect from top-of-the-line equipment.

This year the C8 series and higher models received probably the biggest and most anticipated upgrade in TCL’s history, and it specifically concerns digital image processing. The C8L is the lowest-end model in the manufacturer's lineup to be equipped with the latest flagship chip, the MediaTek Pentonic 800 (listed in the menu as MT9655). Thanks to its processing power, the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively eliminates unwanted posterization (ugly tonal transitions/color banding), doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although evaluating this element can be mostly academic, because the differences between today's TVs in this class are very subtle. The most important takeaway is that TCL finally has nothing to be ashamed of compared to the competition.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as soccer or basketball matches, and the Z95B is no exception. It's also very important that the television is equipped with the proprietary image smoothing system "Intelligent Frame Creation." Among the available sliders, the most important one turns out to be the one named "film smoothness," because it allows adjusting the motion to personal preferences when watching 24-frame material, that is, movies – from a more "frame-like" appearance to a smooth, almost theatrical effect. It's a bit of a shame that Panasonic did not choose to push the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so for everyday viewing this is not a significant drawback as we are limited to 120Hz.

The TCL C8L is equipped with a fast panel that has a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will use a steady 120 Hz. It is at 120 Hz that motion processing algorithms handle image rendering for movies, series, and sports. In the TV’s menu you’ll find a "Motion Clarity" option that lets you adjust the motion smoothing to your preferences. The algorithms handle cinematic material at 24 or 30 frames per second (fps) as well as dynamic sports broadcasts at 50 or 60 fps, maintaining appropriate smoothness.

The Panasonic Z95B is completely equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you can expect from a modern screen. There is VRR frame synchronization, an automatic game mode (ALLM), and full compatibility with HDR formats used in games. The TV supports both Dolby Vision for Xbox and the popular HGiG, which has been implemented correctly in this case, so it actually works as it should.

Although the brand is mainly associated with home cinema and equipment for filmmakers, there is also a place here for conveniences for gamers. It comes with Game Bar (or rather Game Circles) – visually it looks a bit unusual, but it does its job and allows you to quickly check the most important image parameters. What it really lacks for complete happiness is actually just four HDMI 2.1 ports instead of two. It's a minor issue, but one would expect a full set in a TV of this class.

For gamers – especially for those with powerful PCs and several consoles at the same time – the TCL C8L is a true beast. It’s the first model in the manufacturer’s lineup equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly thanks to the new Pentonic 800 processor we wrote about earlier. Additionally, the TV seamlessly supports virtually every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels and full frame synchronization (VRR) operating in an impressive range of up to 288 Hz. We’re also talking about standards like G-Sync or FreeSync from Nvidia and AMD. When it comes to image display standards, there are also no compromises: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. All of these features can be conveniently managed from a very readable game bar (Game Bar), which we can customize according to our preferences. From a purely gaming perspective, there really isn’t anything to complain about in the C8L – well, maybe aside from the previously mentioned slight ghosting. But other than that? It’s an unflawed machine for gamers.
