TCL C6KS / C69KS / Q6CS vs SHARP JP7765E

And what about HDR? Here the C6KS performs quite well and – as is becoming the theme of this review – just like in 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, video materials look good here. However, it's important to keep in mind the specifics of the dimming algorithm in this model. When very small, bright points (e.g. stars) appear on a dark background, the television can quite significantly dim them. The goal is simple: to eliminate blooming and maintain the best possible black. It's a reasonable compromise. Most viewers will definitely appreciate deep, “true black” more than additional microscopic details, the display of which could cause the screen to appear greyed out. Such is the nature of local dimming technology in this price range, and one must be aware of this. It’s also worth noting that the TCL C69KS (C6KS) has an additional PFS coating, which is marketed under the QLED technology slogan. 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%.

So how does the brightness of the Sharp JP7 perform in the most demanding titles? Honestly, we were quite surprised at first. The TV is able to achieve over 1000 nits of brightness, which is an outstanding and rare result for a device costing just under 2000 zł (for 55 inches). Watching bright, full-screen scenes, you can get the impression that you are dealing with really good equipment. But unfortunately, we have to return to the issue we mentioned earlier, which is local dimming management. When small, bright spots appear on a dark background (like in test scenes from the films Life of Pi or Sicario 2), it’s clear how poorly the JP7 handles these zones. The TV dims them almost to the maximum, crushing the whole HDR effect, which at such moments resembles a flat SDR image (less than 200 nits). This instability means that in demanding, contrast-rich films, the image on the JP7 unfortunately loses its appeal.

As a consolation, it's worth noting that the panel has the potential to display colours well. A PFS (phosphor) filter has been employed here, which allows the coverage of the DCI-P3 colour gamut to reach a solid 94%. The manufacturer calls its product a “QLED,” even though it technologically relies mainly on the aforementioned PFS filter. Considering the recent market battles between manufacturers over what can and cannot be called QLED, we leave the issue of the correctness of this terminology to your judgement. However, it remains a fact that the potential for reproducing saturated colours in this panel is simply good.

In contrast to the more expensive C6K model, in the tested C6KS we don't find an option in the menu labelled as Filmmaker Mode. Is this a reason to cry? Absolutely not. Our tests showed 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 profile 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 would give you better colours – the answer is: no, in both cases the base is the same and requires slight adjustments.

When it comes to colours straight out of the box, the Sharp JP7 was tested in the Film mode, which traditionally offers the most cohesive image compared to the yellowed “Eco” mode or the glaring blue of the “Dynamic” mode. Although this is the best choice among the available settings, the results still fall short of ideal. The white balance clearly lacked red and blue components, causing many scenes to take on an unnatural, greenish hue. Another issue was the gamma – in full-screen scenes, the TV produced excessively bright images, completely robbing it of its cinematic character. All of this resulted in colour reproduction errors, especially in shades of grey, which exceeded the Delta E 10 value. To remind you: errors above 2-3 are already noticeable to the human eye, so here we are dealing with a significant distortion of reality.

In HDR mode, the situation is reversed, but not in a better way. Here, the white balance is dominated by blue, giving the image an unnatural, almost “store-like” sharpness, reminiscent of aggressive demonstration modes. Moreover, the measurements of the EOTF curve emphasise the store-like nature of the image. The graph clearly shows that the TV generates images that are significantly brighter than the standards predict, resulting in an artificially boosted and unrealistic final effect. The Sharp JP7 is evidently trying to appear stronger than it actually is, but it does so at the expense of fidelity to the original content.

Thanks to the white balance adjustment, the C69KS's tendency to distort colours has been effectively limited, leading to a very good final effect. After calibration, we will no longer see excessive warmth in SDR scenes or overly cool tones in HDR. However, it is worth noting the brightness characteristic. In SDR content, there are hardly any objections – the image looks very good, especially in older films, TV shows, or YouTube materials. Evaluating the television's performance in HDR is much more difficult. Analysis of the EOTF curve suggests correct behaviour, but its practical variant shows certain limitations. The C69KS can overly brighten the smallest elements of the frame, while at other times it can dim the entire scene. Calibration has therefore brought clear benefits in terms of colour, but certain limitations resulting from local dimming and the way it is controlled by the C69KS cannot be avoided, which we also observed in the C6K test.

We subjected the JP7 to our standard calibration procedure and honestly... the television gained a second life thanks to it, especially with SDR content (YouTube, traditional television, series, or older films). With our precise adjustments to the white balance and stabilisation of the gamma, colour errors dropped to a value of below 3. This is a level at which the human eye struggles to perceive discrepancies. In this scenario, the Sharp JP7 delivers an image with truly excellent colour accuracy, which is a significant advantage in this price range. However, the HDR content turned out to be much more problematic. Here, despite our efforts and interventions in the settings, the television simply refused to cooperate. In the JP7 menu, we won’t find any option to effectively control how brightness is managed (EOTF). Although a significant portion of the colour errors has been reduced, the image still remained unnaturally oversaturated. It’s a bit disappointing because the potential of the mini-LED backlit panel is great, but the software presents a clear barrier.

The conclusion is simple: when watching less demanding content (SDR) on the JP7, you can expect an image that is more than satisfactory, but in HDR you will have to accept a certain degree of "artificiality" that cannot be bypassed even with professional equipment.

The C69KS handles upscaling quite well. The tested 576p content looks surprisingly decent – a considerable amount of detail is preserved, and the algorithm adds a subtle ‘rounding’ effect to sharp edges, making the image appear more cohesive. However, it doesn't perform as well when it comes to smoothing tonal transitions. The television practically cannot improve them, leaving the image in a rather raw state. With older materials, this can be simply exhausting, as the lack of additional processing highlights all imperfections.

When it comes to lower quality materials and how Sharp JP7 handles them, the situation is ambiguous. Let's start with the upscaling itself – here we have no major objections. The process of scaling the image to a higher resolution is correct; the picture remains readable and clear, without the overscan effect, which means no cropped edges. Of course, it's not at the level of top models and at times you can notice slight tearing on the edges, but in this price range, the effect is fully acceptable.

However, the actual digital image processing performs much worse, as aside from the scaling, it practically doesn’t exist. In the JP7 menu, we won’t find any options that would effectively smooth out unwanted tonal transitions or reduce noise in the image. As a result, the signal hits the panel in a very raw form, which with heavily compressed materials (e.g., from YouTube) results in noticeable posterisation. Either this is a programming error or a very strange design decision, because in earlier Sharp models this function was available and, more importantly, worked with noticeable effect. Here, we are stuck with what the source delivers, without any digital support from the image processor.

C69KS offers a simplified motion enhancement panel in movies, allowing users to adjust the intensity of the effect using a slider. This makes it easy to tailor the smoothness to personal preferences. It also deserves credit for the ability to utilise higher refresh rates – even though the panel operates natively in 4K at 60 Hz, by lowering the resolution to 1440p, modes of 120 and 144 Hz can be enabled, on both consoles and PC. This sounds like great news, however, in practice, the image at these settings trails exceptionally badly. The effect is so pronounced that the overall experience simply appears mediocre and loses its appeal in everyday use.

The motion fluidity on the Sharp JP7 is quite average, and the reason is simple: the TV uses a 60Hz panel. This immediately makes it hard to recommend for watching sports or serious gaming, where higher refresh rates are already the standard. The only real plus is the presence of a motion smoother, which we can control in films with a slider called De-judder. Lower settings give a more raw, “cinematic” (framey) image, while higher ones add artificial fluidity. We suggest setting it somewhere in the middle of the scale, around 3-5 – this is the best compromise to avoid the soap opera effect while also getting rid of the annoying image skipping. Interestingly, in the menu, we also find a slider for "motion blur reduction," which usually indicates the presence of a 120Hz panel. However, in the case of the JP7, it doesn’t actually enhance the image and serves more as a dummy – it looks good in the settings, but technically it shouldn’t work on this panel.

If we overlook the smudging and lack of native 4K at 120 Hz, the C69KS is impressive in how well it performs for gaming. You get everything you would expect from a gaming TV: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), Dolby Vision Gaming mode, and a consistently functioning HGiG. The TV can also operate at 120 or even 144 Hz at lower resolutions, making gameplay on console or PC smoother. Additionally, there's a clear Game Bar that allows you to quickly check key settings while gaming. As a result — despite a few limitations — the C69KS can be a genuinely successful screen for gamers.

As we mentioned earlier, the 60Hz panel is not a feature that will attract gamers to the Sharp JP7. Perhaps for the casual gamer, whose console still generates most titles at 60 frames per second, there might be something interesting? When it comes to specific additions, we find here:

• ALLM mode: Automatically switches the TV to low latency game mode (input lag).

• Player menu: Which is hard to call a fully-fledged “Game Bar,” as the functionality is minimal. Aside from enabling ALLM, there’s only a dedicator for gaming which we advise against as it introduces very noticeable artifacts and spoils responsiveness.

• Dolby Vision Gaming: For Microsoft's consoles.

Unfortunately, the list of shortcomings is much longer and more painful than the positives. The biggest disappointment is the lack of support for 120Hz, even when reducing the resolution to Full HD. The presence of 120Hz would allow for performance modes to be activated in many games on the PS5 or Xbox Series X. Another shortcoming is the VRR, which means that during frame drops, we are susceptible to screen tearing. Very problematic is also the lack of proper implementation of the HGiG standard. This results in the fact that during HDR calibration in the console menu, it is very easy to "overshoot" the brightness settings. As a result, instead of clear details in the highlights, we end up with an unnaturally oversaturated image with cut-off details. The Sharp JP7 is a proposal only for those who game very occasionally.
