SHARP JP7765E vs TCL A400 PRO

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.

The TCL A400 Pro is a moderately bright TV. Its peak brightness reaches around 600 nits. That level already allows for a real HDR effect and in many films it does deliver a noticeably more appealing picture than in SDR. However, it’s not a level that dazzles by brightness alone. The A400 Pro is not one of those TVs that bombard the viewer with a powerful flash in every dramatic scene. The biggest limitation is visible with small bright elements on a dark background. Because of fairly aggressive zone control, the TV can significantly reduce their brightness, in extreme cases down to around 100 nits. That means small lights, sparks, stars or single highlights can be much less visible than they should be. It should be added, though, that this isn’t done without reason. The A400 Pro does this to keep black levels as deep as possible and to limit the halo effect around bright objects. It’s a deliberate compromise: the TV more often opts for deeper blacks rather than maximising point highlights. On the one hand this is understandable, especially given a limited number of dimming zones, but on the other you should be aware that the HDR effect won’t always be as strong as the peak brightness alone might suggest.

On the plus side, the colours are a strength. The PFS LED filter used here, marketed by the manufacturer as QLED, delivers suitably saturated colours. Our measurements showed about 94% coverage of the DCI-P3 gamut and around 74% of BT.2020, which is a solid result for this class.

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.

As usual, we carried out colour measurements in the best‑tuned picture mode, Filmmaker Mode, the one intended to be closest to the creators’ intentions. The A400 Pro, of course, also offers other picture modes, but in practice they show much larger colour errors and interfere more with the image character. So we won’t cover them in detail in this part of the review. How does the factory colour reproduction fare? In short: really very well. In fact, looking at our measurements, it’s excellent. Both the white balance and the luminance response were set surprisingly precisely. The errors were so small that during the measurements we genuinely rubbed our eyes in surprise. Such good factory settings don’t happen often, even in televisions running Filmmaker Mode. All the more reason to praise TCL, because the A400 Pro straight out of the box can produce an image very close to how the source material should look. The results were so good you could easily think someone had already given this unit extra attention and tried to calibrate it. Our one bit of nitpicking comes down to a single issue. In SDR material the image was slightly brighter than the reference for a dark room, because the factory gamma was set closer to 2.3 than 2.4. It’s not a large error and most viewers probably won’t even notice it. We should note, however, that we are talking about our specific test unit. There can always be some variation in factory colour between individual units, production batches or screen sizes. We do not assume every A400 Pro will look identical straight out of the box.

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.

Despite the outstanding factory tuning, we couldn't resist checking how the TCL A400 Pro would respond to professional calibration. With such a strong starting point, we were especially curious whether we could squeeze even more from this TV. And here we have to boast: we managed to bring our sample to absurdly low colour errors. Results below 1 are something you don't see every day, even on very good TVs. Such outcomes are more often associated with professional reference monitors than with a lifestyle TV for the living room. In terms of white balance and colour reproduction, the A400 Pro after calibration simply excelled. The only thing we can pick on after closer analysis concerns the brightness response. The TV can vary the luminance level depending on the content being displayed, and quite often the picture is a little darker than it should be according to the reference. This most likely stems from the way the Mini-LED backlight and the local dimming algorithms work in this model. That said, it doesn't ruin the overall impression, because in terms of colour precision the A400 Pro after calibration reached a level that was genuinely hard to expect.

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.

Digital image processing is unfortunately one of the weaker points of the TCL A400 Pro. That does not mean the TV performs badly, but it’s hard to call it anything clearly above standard. The upscaling itself is acceptable: edges are fairly well smoothed, the picture does not look overly sharp or “pixelated”, and lower-quality material can be watched without major discomfort. At the same time the overall image has a slightly soft character and you don’t see the kind of precision that the best image processors in more expensive TVs can offer.

Handling of tonal transitions caused by heavy compression is much worse. TCL equipped the A400 Pro with a “Gradual Smoothing” feature that in theory should reduce visible colour banding and artefacts in lower-quality material. In practice, however, its effectiveness is very limited. It does not improve tonal transitions in any noticeable way, and at higher settings it can further smooth image detail, giving it an artificial, slightly blurred character. For that reason we think it’s best to leave this feature off. The A400 Pro copes decently with basic image scaling, but if you often watch heavily compressed material with visible posterisation, this model will not be one of the best choices.

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.

The TCL A400 Pro is equipped with a 144 Hz panel, but in practice we're most interested in how it performs at 120 Hz. That's the refresh rate most consoles, as well as many sports broadcasts and high-motion sources, are limited to today. In that range the TV performs quite well. Motion clarity is really good, especially after properly configuring the motion smoothing. The 'Motion Clarity' function improves smoothness. Its settings include two sliders that let you tailor the motion smoothing to your preferences, separately for low-frame-rate and high-frame-rate content. This allows you to achieve either a more cinematic look or a noticeably smoother image. If you don't want to fiddle with manual configuration, you can use built-in presets such as Low, Medium, High, Cinema or Nature.

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.

In terms of gaming features the TCL A400 Pro performs brilliantly. The TV has practically everything you’d expect from a gaming TV today: support for 4K at high refresh rates, VRR, ALLM, correct implementation of HDR formats in games, including Dolby Vision, and HGiG. That means it works well with both next‑gen consoles and PCs. Another plus is the inclusion of a Game Bar, a dedicated panel with the most important settings for gamers. From it you can quickly check basic information about the signal, refresh rate or active features, and customise the appearance and behaviour of some settings to your preferences. It’s a solution that may not change picture quality by itself, but it greatly improves the convenience of using the TV while gaming. The only thing to criticise is the number of full HDMI 2.1 ports. The A400 Pro has only two such ports out of four, and one of them also serves as eARC. In practice this means that if you want to connect two next‑gen consoles and a soundbar you may run into some limitations. In that scenario you’ll need to either swap devices or use extra equipment, such as an AV receiver or a soundbar with HDMI inputs. Even so, it’s hard not to rate the A400 Pro very highly as a gaming TV. The gaming feature set here is genuinely powerful.
