SHARP JP7765E vs LG OLED B6

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.

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

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.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

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.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED 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.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

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.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

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.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.
