SHARP JP7765E vs TCL P7L / P79L

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 biggest limitation of the TCL P7L in HDR is simply brightness. The TV doesn't have much luminance headroom, so strong highlights, sunlight or small light sources can't clearly "pop" out of the image. As a result, even well-produced HDR material looks fairly restrained and, in terms of dynamics, is closer to good SDR than to what brighter models show. That doesn't mean the P7L completely fails at HDR; the issue is mainly a lack of sufficient backlight power. Looking at colours, the situation is a bit better. The TV covers roughly 91% of the DCI‑P3 gamut and about 68% of the wide BT.2020 space, so for its price class the colour range is quite decent. TCL markets this model as QLED, although the nature of the solution used is closer to a PFS phosphor‑based backlight than a classic quantum dot layer. What matters most to the viewer is the effect: more saturated colours are on offer.

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.

In Film mode the TCL P7L performs quite decently without major tweaks, especially with ordinary SDR material. The white balance is relatively even, although as brightness increases there’s a slight rise in red and blue and a bit too little green. That doesn’t create a strongly visible colour cast and most colours remain close to their reference points. The Colour Checker confirms this, with a large portion of errors falling below the level that should particularly bother during normal viewing. We have more remarks about the gamma response. In the darkest parts of the image the TV drives it noticeably above the reference, so some shadow detail may be a little too dim. The curve then settles and for much of the range it’s close to the intended targets. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety.

In HDR the factory setup is less precise. As brightness increases the excess blue becomes more pronounced, so the picture can look cooler than it should. The number of larger colour deviations also rises, especially in brighter colours. The EOTF curve itself is handled fairly conservatively, with the TV showing the image darker than the reference over much of the range. For such an inexpensive model, the factory Film mode settings are not bad.

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.

After calibration the TCL P7L can produce a genuinely pleasant picture, especially with conventional SDR material. We managed to even out the white balance very well, and the gamma curve now tracks close to the target value of 2.4. This is also evident in the colour measurements, as most errors have fallen significantly and in everyday viewing it’s hard to notice any major inaccuracies. Films, series, YouTube and regular TV therefore look more natural, without unnecessary warmth or a cool tint. For a model at this price point the SDR result is really very good.

In HDR the situation becomes more complicated. Calibration improved the white balance and corrected some deviations, but here the panel’s limitations become increasingly apparent. The P7L has relatively limited brightness and can’t sustain appropriate luminance for more saturated colours, so some errors remain even after careful tuning. In other words, settings can improve how the TV interprets the signal, but you can’t overcome its physical capabilities. That’s why calibration is most worthwhile for SDR on this model.

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.

In this respect the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The banding reduction feature, which in many budget models does little or nothing, actually manages to improve the picture here. It doesn't remove all banding completely, but it can noticeably reduce posterisation and make trickier gradients look more natural. In this price segment that's a genuinely pleasant surprise.

The upscaling itself also looks good. Lower-resolution material is upscaled properly, without excessive sharpening or adding artificial edges around objects. Of course the P7L won't turn a very poor source into a 4K-quality picture, but for regular TV the result is simply solid. For a model at this price point there are few major complaints to make.

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.

TCL P7L uses a native 60 Hz panel at 4K resolution, and that's how it should be treated in everyday use. For movies the TV mainly offers frame interpolation, so it can smooth motion and reduce noticeable judder, but it doesn't deliver the smoothness typical of true 120 Hz panels.

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.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR and Dolby Vision in games, and TCL also includes its Game Bar, where you can quickly check key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn't work here as it should, but at this price point it's hard to complain much about the feature set. The most interesting part comes when you give up 4K. At that resolution the TV runs at up to 60 Hz, but at 1440p and 1080p it can already display at 120 Hz. And that's not just a spec-sheet curiosity. In fast-paced games that support that frame rate the difference in smoothness is genuinely noticeable, so if you care more about smoother motion than maximum image sharpness, that mode can make a lot of sense. Of course, that doesn't make the P7L a true 120 Hz TV. Still, it's precisely these extra modes that make the P7L perform really well for gaming.
