Panasonic Z95B vs TCL C6KS / C69KS / Q6CS

The quality of HDR on the Panasonic Z95B is among the absolute best. Thanks to the latest generation panel, referred to by the manufacturer as Primary RGB Tandem OLED, the television can achieve over 2000 nits of brightness in cinematic scenes. The effect is impressive and can amaze with the intensity of the light, providing a sense of connection with the screen that goes beyond previous experiences. Similar feelings 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 concerns full-screen bright sequences, such as the closing credits in the film The Meg. Even then, the Z95B maintains a level of around 1500 nits, which is still an incredibly impressive result. One can thus say that HDR in this model has reached masterful form. A significant step forward is also evident in colour reproduction. 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 decreased. When watching films, the differences are subtle enough that under normal conditions they are hard to notice, and the colours remain vivid and saturated.

And what about HDR? Here, the C6KS performs quite well and – as has become a recurring theme of this review – identically to the C6K model. The maximum brightness generated by this television is around 600 nits. In bright scenes, this translates to a really solid, cinematic effect, and generally, the video materials look good here. However, one must keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g., stars) appear against a dark background, the television can dim them quite significantly. The goal is simple: to eliminate blooming and maintain the best possible blacks. This is quite a reasonable compromise. Most viewers will definitely appreciate deep, "true black" more than additional micro-details, the display of which could cause the screen to appear greyed out. This is the nature of local dimming technology in this price range, and one must be aware of it. It is also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the slogan of QLED technology. Thanks to this, the colours are saturated and vibrant – our measurements showed that the coverage of a wide colour gamut reaches as much as 92% here.

The factory colour reproduction of the Filmmaker mode, my dear friends, is truly remarkable in the case of the Panasonic Z95B. I'm referring to our test sample, but the result was so good that it’s hard to believe. The only detail one might nitpick about is a slight lack of blue in the white balance, but apart from that, the television straight out of the box presented an image unlike anything we have ever seen in factory mode. Tests of the colour palette, Color Checker – everything indicated values below Delta 2. That’s a much lower result than the threshold of human eye perception, which means, quite simply, that the viewer has no chance of noticing any serious deviations. It looks as though Panasonic has actually calibrated this model at the factory stage. Of course, we cannot rule out the possibility that we received an exceptionally well-set sample, but the result is still impressive. We are very strict when it comes to evaluating factory calibration, and here our jaws simply dropped.

Unlike the more expensive C6K model, the tested C6KS does not have an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests have shown that in practice, in terms of colour reproduction, the lack of this specific label makes virtually no difference. The best available Film/Cinema mode here offers an almost identical picture characteristic to the aforementioned Filmmaker in the more expensive model. So we get a very similar image, just under a different name. Therefore, if you were wondering whether paying extra for the C6K gives you better colours – the answer is no, in both cases the base is the same and requires slight adjustments.

The colour representation after calibration in the Z95B is a topic that is difficult to elaborate on, as there was simply not much to be done here. A slight adjustment of the white balance was sufficient to eliminate the lack of blue, and at this point, the picture reached an almost reference level. It must be admitted that we haven't had such a small range of work in a while. If any of you are particularly observant, you may notice minimal deviations in the EOTF curve, but this is rather related to the operation of the dynamic tone mapping function we mentioned earlier. In fact, it is not a flaw, but a characteristic of this solution, which deliberately alters the brightness characteristics depending on the scene. In summary, we are extremely impressed. The Panasonic Z95B is a television that looks great straight out of the box, and after calibration, it reaches a level where it is truly difficult for us to find anything to improve.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, resulting in a very good final effect. After calibration, we will no longer see excessive warming of scenes in SDR or overly cool tones in HDR. However, it is worth noting the brightness characteristics. In SDR content, it is hard to have any objections – the image looks very good, especially in older films, television programmes, or materials from YouTube. It is significantly more challenging to evaluate the television's performance in HDR. Analysis of the EOTF curve suggests correct behaviour, but its practical variant reveals certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times, it can dim the entire scene. Thus, calibration brought clear benefits in terms of colour quality, but certain limitations resulting from the local dimming operation and the way it is controlled by the C69KS cannot be overlooked, as we also saw in the C6K test.

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

The situation with digital processing is less impressive. Features such as “gradation smoothing” or “block noise reduction” practically do not work – the material tested looked identical regardless of the settings. We might as well state that this feature simply does not exist. This is somewhat disappointing, especially since Panasonic heavily promotes its HCX Pro AI II processor, boasting the presence of artificial intelligence to enhance picture quality. Meanwhile, in such a basic area, the television does not provide a real effect and it appears weaker than one might expect from high-end equipment.

The C69KS handles upscaling quite well. The tested 576p material looks surprisingly decent – a considerable amount of detail is retained, and the algorithm adds a slight "rounding" effect to sharp edges, making the image appear more cohesive. The performance in smoothing tonal transitions is less impressive. The television practically cannot improve them, leaving the image in a rather raw state. With older material, this can be quite tiring, as the lack of additional processing highlights any imperfections.

The OLED matrix with a very high refresh rate already provides an extremely sharp image even in dynamic sports scenes, such as football or basketball matches, and the Z95B is no exception. It is also very important that the television is equipped with an proprietary motion smoothing system called “Intelligent Frame Creation”. Among the available sliders, the most important one is the one named “film smoothness”, as it allows you to adjust motion to your own preferences when watching 24-frame materials, i.e. films – from a more “frame-like” appearance to a smooth, almost theatrical effect. It is somewhat disappointing that Panasonic did not choose to overclock the latest OLED matrix to 165 Hz, as Samsung did with the S95F or LG with the G5, because we know that the panel is technically capable of it. On the other hand, this is mainly an advantage for PC gamers, so in everyday viewing, it is not a significant drawback since we are limited to 120Hz.

C69KS offers a simplified motion enhancement panel in films, allowing the adjustment of effect intensity with a slider. This makes it easy to match fluidity to personal preferences. The ability to use higher refresh rates is also a plus – although the panel operates natively at 4K at 60 Hz, lowering the resolution to 1440p enables 120 and 144 Hz modes, both on consoles and PC. This sounds like great news, however, in practice, the image at these settings exhibits significant motion blur. The effect is so pronounced that the overall presentation appears merely average and loses its appeal for everyday use.

The Panasonic Z95B is fully equipped for gaming. Two HDMI 2.1 ports with full bandwidth of 48 Gb/s guarantee support for everything you would expect from a modern screen. There is VRR frame synchronization, an automatic ALLM game mode, and full compatibility with HDR formats used in games. The television 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 room here for features for gamers. On board, there is a Game Bar (or rather Game Circles) – visually, it looks a bit unusual, but it serves its purpose and allows you to quickly check the most important picture parameters. The only thing that is actually missing for complete happiness is having four HDMI 2.1 ports instead of two. It's a minor detail, but in a television of this class, one could expect a full set.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS impresses with how well it performs during gaming. We get everything one can expect from a gaming television: variable refresh rate (VRR), automatic switching to game mode (ALLM), Dolby Vision Gaming mode, and a well-functioning HGiG. The television can also operate at 120 and even 144 Hz at lower resolutions, allowing for smoother gameplay on a console or PC. Additionally, there is a clear Game Bar that lets you quickly glance at key settings while gaming. As a result — despite a few limitations — the C69KS can be a really successful screen for gamers.
