SHARP JP7765E vs TCL C7L

So how does the brightness of the Sharp JP7 perform in the most demanding titles? Honestly: at first, we were quite surprised. The television is capable of achieving over 1000 nits of brightness, which is an outstanding and rarely seen result for a device costing just under 2000 zł (for 55 inches). Watching bright, full-screen scenes, one can get the impression that we are dealing with truly good equipment. However, unfortunately, we must return to the problem we mentioned earlier regarding local dimming management. When small, bright elements appear on a dark background on the screen (like in the test scenes from Life of Pi or Sicario 2), it is noticeable how poorly the JP7 handles the zones. The television dims them almost to the maximum, stifling the whole HDR effect, which at such moments resembles a flat SDR image (less than 200 nits). This instability makes the image on the JP7 unfortunately lose its appeal in demanding, contrast-heavy films.

As a consolation, it is worth noting that the panel has the potential for good color display. A PFS (phosphor) filter has been implemented here, allowing the coverage of the DCI-P3 palette to reach a solid 94%. The manufacturer calls its product a “QLED,” even though it is mainly based technologically on the aforementioned PFS filter. Considering the recent market battles among manufacturers about what can and cannot be called QLED, we leave the issue of the correctness of this naming to your judgment. However, it remains a fact that the potential for reproducing saturated colors in this panel is simply good.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness levels of around 2800 nits. This is an absolutely phenomenal result, considering the price range it falls into. Unfortunately, the tests with real film scenes are not as spectacular as the measurements of white squares. The brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as the vast majority of contemporary films are mastered at such a value. However, when small, pinpoint elements appear on the screen, the brightness of those details drastically drops – even to about 400 nits – which diminishes the HDR effect somewhat. The television does this intentionally to maintain a better level of black and prevent a huge glare of light. This is somewhat explainable, but it also shows that Mini LED technology is not completely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colors are obviously key here. And these, thanks to the use of new, "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve around 90% coverage of the ultra-wide color gamut BT.2020 and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such high color saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED televisions.

When it comes to out-of-the-box colors, the Sharp JP7 was tested in Film mode, which traditionally offers the most consistent 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 are still far from ideal. The white balance clearly lacked red and blue components, causing many scenes to take on an unnatural, greenish tint. Another issue was the gamma – during fullscreen scenes, the television provides too much brightness, completely stripping away its cinematic character. All of this translated into color reproduction errors, particularly with shades of gray, which exceeded Delta E 10. Just to remind: 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 any better. Here, the blue color dominates the white balance, giving the image an unnatural, almost “store-like” sharpness reminiscent of aggressive demo modes. Furthermore, the measurements of the EOTF curve emphasize the store-like nature of the image. The graph clearly shows that the television generates an image 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 content.

When it comes to colors straight out of the box, a new feature in TCL televisions – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was previously unavailable from this manufacturer. By design, as the name itself suggests, the image in this setting is intended to be presented with the full intent of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful color reproduction straight out of the box. However, we definitely wouldn't say that it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode strayed into a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue color. Of course, for the average viewer, this may not be a drastic flaw, but if you care about perfect whites, natural skin tones, and fully unlocking the potential of these new "super" quantum dots, this television is in need of professional calibration.

We subjected the JP7 to our standard calibration procedure and truly... the television gained a new life thanks to it, especially in SDR content (YouTube, classic television, series, or older movies). Because we managed to accurately set the white balance and stabilize the gamma, color errors dropped to a value of below 3. This is a level at which the human eye has trouble detecting discrepancies. In this scenario, the Sharp JP7 delivers an image with really great color accuracy, which is a significant advantage in this price range. However, the content in HDR turned out to be much more problematic. Here, despite our efforts and adjustments to the settings, the television simply did not want to cooperate. In the JP7 menu, we cannot find any option that would allow for real control over brightness management (EOTF). Although a significant portion of color errors was reduced, the image still remained unnaturally oversaturated. It's a pity because the potential of the mini-LED backlit panel is large, 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 have to come to terms with a certain degree of "artificiality" that cannot be overcome even with professional equipment.

After conducting a professional calibration, we managed to significantly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide color gamut dropped below the threshold of human perception – that is, below a value of 3, which is indeed a very good result. The TCL C7L definitely benefits from such an intervention in terms of color fidelity, and it's hard to dispute that. However, the management of brightness in HDR content post-calibration looks a bit worse. As I described earlier – even though we set up this model properly, when we turn on actual film scenes on the TV, it manages its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which is clearly visible in the EOTF graphs measured in specific films. Despite this defect – or rather a specific characteristic of this television – one cannot take away from it that after calibration, the C7L was able to reproduce the colors completely accurately.

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

However, the digital image processing itself is significantly worse, as aside from the scaling, it virtually does not exist. In the JP7 menu, we won't find any option that would effectively smooth out unwanted tonal transitions or reduce noise in the image. As a result, the signal reaches the matrix in a very raw form, which, with heavily compressed materials (e.g., from YouTube), leads to visible posterization. Either this is a flaw in the software or a very strange design decision, as in earlier Sharp models, this feature was available and, more importantly, worked with noticeable effect. Here we are left at the mercy of what the source provides, without any digital support from the image processor.

This point can be, in a sense, called the Achilles' heel of the C7L model. Unfortunately, this TV uses an older MediaTek chipset – the Pentonic 700 – which has never been known for exceptional digital image processing. This is clearly evident in the operation of the gradual smoothing feature, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – after setting it to low, its effectiveness is practically nonexistent. The only small plus here is that the algorithm doesn't spoil anything additional in the image and doesn’t forcibly blur details. The upscaling, that is, scaling the image from lower resolutions to 4K, performs a bit better. It is simply adequate and doesn’t stand out in any particular way compared to the competition. However, it cannot be denied that the C7L would gain significantly in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now increasingly found in many competitive models.

The motion fluidity on the Sharp JP7 is very mediocre, and the reason is simple: the television uses a 60Hz panel. This immediately makes it difficult 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 movies using a slider called De-judder. Lower settings produce a more raw, "cinematic" (frame-based) image, while higher settings add artificial fluidity. We suggest setting it somewhere in the middle of the scale, that is, in the 3-5 range – this is the best compromise to avoid the soap opera effect while getting rid of the tiring image stutter. Interestingly, in the menu, we also find a slider for "motion blur reduction," which usually suggests the presence of a 120Hz panel. However, in the case of the JP7, it does not contribute anything to the image and serves more as a placeholder – it is meant to look good in the settings, but technically it should not function on this panel.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which can even ramp up to 288 Hz at lower resolutions when using a PC. These are, of course, very high values and commendable on paper, but in everyday life, it's worth remembering that nearly all dynamic content you display on this television will still be running around a maximum of 120 Hz. To harness this dynamics, we find a motion smoothing system in the TV's menu called “Motion Clarity.” It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-true guides on our YouTube channel. There we have two key sliders at our disposal. The first one, “Blur Reduction,” is responsible for reducing blurring and improving sharpness in dynamic 60fps materials, such as sports broadcasts. The second slider, “Flicker Reduction,” allows for the addition of artificial frames in movies and series recorded at cinematic 24 or 30 frames per second. This, of course, completely eliminates the irritating stutter effect during camera movement shots.

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 generates most titles at 60 frames per second, there might be something interesting? When it comes to specific additions, we find:

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

• Game Menu: Which is hard to call a full-fledged “Game Bar,” as its functionality is minimal. Besides enabling ALLM, there is only a smoothness enhancer dedicated to games, which we recommend against because it introduces very noticeable artifacts and spoils the 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 lowering the resolution to Full HD. The presence of 120Hz would allow for performance modes to be activated in many games on PS5 or Xbox Series X. Another absence is VRR, which means that during frame drops, we are susceptible to image tearing. The lack of proper implementation of the HGiG standard is also very problematic. 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 highlights, we end up with an unnaturally over-brightened image with cut-off details. The Sharp JP7 is a proposal only for very casual gamers.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, we have access to all the key features that console owners and powerful PC users require. It offers a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates impressively from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a well-designed gaming panel, the Game Bar, which even allows for customization of its appearance and theme to perfectly match the aesthetics of your console.

The only thing that can – and indeed must – be criticized here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home theater system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you will have to give up something or constantly juggle the cables at the back of the unit while maintaining convenient audio system control.
