Sharp GP7 vs Hisense UR8S

In terms of HDR, Sharp GP7 can pleasantly surprise us. A maximum brightness of around 500 nits is the threshold at which the real benefits of high dynamic range become visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to clearer differentiation of elements in both bright and slightly darker scenes. Additionally, the DCI-P3 colour space coverage was around 95%, allowing for vibrant, visually pleasing colours. Of course, this is not the highest league, but considering this price range – it’s a big plus.

UR8S is a slightly higher-end Mini-LED, so you could expect a lot in terms of brightness. And indeed, on a synthetic test pattern peak brightness reached around 2200 nits. That’s a very good result, but as always what’s much more important is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes, where there’s a lot of light on screen, the UR8S can deliver really strong HDR. Brightness then reaches about 1500 nits, so the image is very intense and has plenty of punch. It’s worse with small bright elements on a dark background. The TV clearly dims them to keep good blacks and to prevent excessive bloom. As a result things like single stars or tiny reflections can be only around 200 nits. And here HDR is no longer as impressive. So you can see that the local dimming algorithm works effectively, but it also has its cost: sometimes it simply sacrifices the brightness of small details in favour of contrast.

Colours

With RGB Mini-LED TVs colours should be judged a little differently than usual. If we look solely at the panel’s native capabilities, the UR8S performs excellently. We measured around 94% coverage of BT.2020 and practically full DCI-P3. These are among the highest values currently found in LCD TVs and this is where the potential of the RGB backlight is most obvious. The problem is that this potential is not always realised in real scenes. When we ran the same measurements on test patterns with a film background applied, saturation of some colours began to fall noticeably. Individual zones are not always able to control the three RGB components so precisely when the scene becomes more complex. This is most visible with blue and magenta. On simple test patterns they can look very strong, but in more demanding scenes samples of those colours visibly shrink. So the UR8S’s capabilities are enormous, it’s just that the TV cannot fully make use of them in every scene.

Upon removing it from the box, in movie mode, GP7 does not perform poorly at all. In HD materials, we noticed slight disturbances in white balance – drops in red and blue, which made the image have a somewhat greenish hue. This is evident, for example, on the faces of characters, which become less three-dimensional. The gamma is somewhat brightened in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone additionally comes to the fore, making the colours appear less natural. On the other hand, looking from the perspective of "straight out of the box," these settings are not bad – only minor adjustments are needed, and with the help of specific tools, we will try to improve them.

For assessing the out-of-the-box colours we used Filmmaker mode, which is intended to show an image that is as close as possible to how the material was prepared. Looking at the white balance alone, the UR8S performs quite well. There is no strong tint that immediately jumps out, although as brightness increases a little too much blue and red start to appear, with a simultaneous shortfall of green. Colour errors therefore show up in measurements, but the image itself does not look bad. We have far greater reservations about how the UR8S manages picture brightness. In SDR the gamma sits around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the picture is too bright, especially in the midtones. Shadows are lifted too much, causing the image to lose some depth. A similar tendency is visible in HDR. The EOTF curve is above the reference value for a large part of its range, so the UR8S again brightens the image more than it should. This is not due to a lack of brightness — the TV has plenty — but to the way it manages that brightness. As a result, HDR content can look very striking, but not always precisely as it should.

Calibration really makes a difference in Sharp GP7. After making adjustments, we achieved a better white balance in HD content, and the colours began to appear much more natural, with minimal deviations and without a noticeable dominance of individual hues. In 4K HDR, the change is not as spectacular, but still noticeable. The gamma has been brought to a more neutral level, although there remains an issue with a slight boost in the brightest details on the screen. The lack of control over dynamic tone mapping limits our manoeuvrability, but nonetheless, it is a significant step forward compared to the factory settings.

Hisense provides plenty of calibration options and, in SDR, these can yield a very good result. After calibration, the white balance is practically even across the entire range, and colour errors fall to very low values. The UR8S can be adjusted very precisely here. HDR is somewhat different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations begin to appear. The most interesting aspect, however, is the behaviour of the EOTF curve. Even after it has been correctly set on test patterns, the UR8S still tends to interpret brightness in its own way when watching films. Depending on the scene, parts of the image are slightly brightened while others are dimmed relative to how they should appear. This shows that the algorithms controlling the local dimming have a significant influence on the final image. Calibration therefore allows colours to be improved very effectively, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

The television is quite capable of scaling lower quality content. Our test patterns were well reproduced, and although there was minimal banding on fine, delicate shapes (for example, thin branches), it still looked satisfactory. Additionally, Sharp GP7 offers a "10-bit colour reproduction" feature to smooth tonal transitions in poor quality materials. It is useful, but at the cost of some details, so we recommend turning it on only when we are truly watching something subpar.

A big plus of the UR8S is the use of the MediaTek Pentonic 800 processor, and digital image processing is one of this model's stronger points. The TV handles smoothing tonal transitions very well, especially with lower-quality content. The feature responsible for this effect works effectively without overprocessing the picture. Even on the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image is not overly sharpened. The UR8S simply copes very well with a weaker signal, and in this respect it is one of its most notable strengths.

With a 60 Hz panel and an average response time, it’s hard to expect miraculous smoothness. In dynamic tests, such as the one with the “little green man”, it’s evident that the picture can stutter and occasionally lose sharpness. For watching films and series, this is acceptable, especially as you can make use of a motion smoother with three levels of adjustment. However, if we are keen on ultra-smooth sports broadcasts or super-responsive gaming, we may feel unsatisfied.

The UR8S is equipped with a panel with a native 180 Hz refresh rate, so right from the start it offers excellent motion handling. The panel itself performs really well here, although some limitations typical of VA panels are still visible. Motion blur is relatively minor for this type of screen, but with faster motion (especially on darker backgrounds) it can still be noticed, particularly when compared with the same image on OLED TVs.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, it has ALLM which automatically switches the TV to low latency mode, but it lacks VRR or G-Sync. We also won't find any advanced menu to assist in selecting settings during gameplay. Dolby Vision in games? It's there, but with such a high input lag that it's hard to speak of comfort. If we play occasionally and are not aiming for the highest standards, it can be managed, but fans of technological innovations will be disappointed.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you can expect from a modern console or PC display. It offers ALLM, VRR and 4K at 120 Hz. There is also Dolby Vision in Game Mode, so when using, for example, the Xbox Series X you do not have to give up that HDR format. PC gamers get even more options. The panel can run at 4K at 180 Hz, and dropping to Full HD can raise the refresh rate to as much as 330 Hz. There is also a Game Bar that lets you quickly check key information and change gaming-related settings. The only clear omission is a correct implementation of HGiG. With it enabled the TV still alters HDR brightness mapping, so we do not get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
