Sharp GP7 vs Hisense UR8S

In terms of HDR, Sharp GP7 can surprise us pleasantly. The maximum brightness of around 500 nits is the threshold at which the real advantages of high dynamic range begin to be visible. During our tests, we achieved stable values between 430 and 500 nits, which translated to a clearer distinction of elements in both bright and slightly darker scenes. Additionally, it has a DCI-P3 colour gamut coverage of about 95%, allowing for vibrant, visually pleasing colours. Of course, it isn't top-tier, but for this price range – a big plus.

UR8S is a higher-end Mini-LED, so you could expect plenty of brightness. Indeed, on a synthetic test pattern peak brightness reached about 2200 nits. That’s a very good result, but as always what the TV does in normal film scenes matters much more. Here the results are a bit more mixed. In bright scenes with lots of light on screen, the UR8S can deliver very strong HDR. Brightness then gets up to around 1500 nits, so the image is very intense and has a lot of punch. It’s worse with small bright elements on a dark background. The TV noticeably dims them to preserve deep blacks and avoid excessive blooming. As a result, things like single stars or small specular highlights can be only around 200 nits. And here HDR is no longer as impressive. So the local dimming algorithm works effectively, but it comes at a cost — sometimes it sacrifices the brightness of small details too much in favour of contrast.

Colours

For RGB Mini-LED TVs, colours should be evaluated a little differently than usual. If we look only at the panel’s capabilities, the UR8S performs excellently. We measured about 94% coverage of BT.2020 and virtually full DCI-P3. Those are among the highest figures currently seen in LCD TVs, and this is where the potential of the RGB backlight is most apparent. The problem is that this potential isn’t always used in real scenes. When we ran the same measurements on patterns overlaid with a film-like background, saturation of some colours started to fall noticeably. Individual zones can’t always control the three RGB components with the same precision when the scene becomes more complex. It’s most noticeable with blue and magenta. On simple test patches they can look very strong, but in tougher scenes samples of those colours clearly shrink. In other words, the UR8S has huge potential, but the TV can’t always take full advantage of it in every scene.

Out of the box, in movie mode, GP7 doesn't fare badly at all. In HD materials, we noticed slight disturbances in white balance - drops in red and blue that made the image take on a somewhat greenish hue. This is noticeable, for instance, on the faces of characters, which become less lifelike. The gamma is slightly brighter in places, resulting in less deep blacks. In 4K HDR content, a cooler, bluish tone also emerges, making the colours appear less natural. On the other hand, looking at it from a "straight out of the box" perspective, these settings aren't bad - a few minor adjustments will suffice, and with the help of special tools, we will try to improve them.

For evaluating the factory colours we used Filmmaker mode, which is supposed to show the image as close as possible to how the content was prepared. And if you look at the white balance alone, the UR8S performs quite well. There’s no strong tint that immediately jumps out, although as brightness increases a bit too much blue and red start to appear, with a corresponding lack of green. Colour errors are therefore visible in measurements, but the image itself doesn’t look bad.

We have much bigger reservations about how the UR8S manages image brightness. In SDR the gamma stays around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the image is too bright, especially in the midtones. Shadows are lifted too much, so the picture loses some depth. A similar tendency is visible in HDR. The EOTF curve sits above the reference value for a large part of the range, so the UR8S again brightens the image more than it should. This isn’t a case of the TV lacking brightness, because it has plenty, but of how it manages that brightness. As a result, HDR material can look very striking, but not always exactly 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 started to look much more natural, with minimal deviations and no clear dominance of individual hues. In 4K HDR, the change isn't as spectacular, but it's still noticeable. The gamma has been brought to a more neutral level, although a slight boost in the brightest details on the screen is still evident. The inability to control dynamic tone mapping limits our manoeuvrability, but nonetheless, this is a significant step forward compared to the factory settings.

Hisense offers quite a lot of calibration options, and in SDR you can achieve a really good result with them. After adjustment the white balance is practically even across the whole range, and colour errors fall to very low values. The UR8S can be set very precisely here. HDR looks a little different. The white balance can also be noticeably improved, although at the highest brightness levels larger deviations start to appear. Most interesting, however, is the behaviour of the EOTF curve. Even after correctly setting it on test patterns, the UR8S can still interpret brightness in its own way when watching films. Depending on the scene, parts of the picture are slightly brightened and others darkened compared with how they should look. This shows that the algorithms controlling the backlight have quite a large influence on the final image. Calibration therefore allows colours to be improved very well, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

The TV can scale lower quality content quite well. Our test patterns were well reproduced, and although there was minimal banding with fine, delicate shapes (such as 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're really watching something of poor quality.

The big plus of the UR8S is its 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 poorer-quality material. The feature responsible for this effect works effectively without overprocessing the picture. Even on a medium setting it can noticeably reduce visible banding and artefacts without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image isn’t over-sharpened. The UR8S simply copes very well with weaker signals, and in that respect it’s one of its clear strengths.

With a 60 Hz panel and average response time, it's hard to expect miraculous smoothness. In dynamic tests, like the one with the “little green man”, it’s clear that the picture can blur and occasionally lose sharpness. For watching movies and series, this is acceptable, especially since you can use the motion smoother with three levels of adjustment. However, if we care about ultra-smooth sports broadcasts or super-responsive gameplay, we might feel a bit dissatisfied.

The UR8S is equipped with a panel that has a native 180 Hz refresh rate, so right away it offers very strong potential for smooth motion. The panel itself performs really well, although some limitations typical of VA panels are still visible. Smearing is relatively low for this type of screen, but during faster motion, especially on darker backgrounds, it can still be noticed, particularly if you compare the same image to OLED TVs.

Let's not kid ourselves – GP7 Sharp is not a television for the most demanding console gamers. Yes, we have 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 help adjust settings during gameplay. Dolby Vision in games? It's there, but with such a large input lag that it's hard to talk about comfort. If we play occasionally and don't aim for the highest standards, it can be managed, but tech enthusiasts will face disappointment.

In terms of gamer features the UR8S stacks up really well. The TV supports virtually everything you'd expect from a modern console or PC display. It has ALLM, VRR, and 4K at 120 Hz. There's also Dolby Vision in game mode, so when using, for example, an Xbox Series X you don't have to give up that HDR format. PC gamers get even more options. The panel can run at 4K and 180 Hz, and dropping to Full HD can push the refresh rate as high as 330 Hz. There's also a Game Bar that lets you quickly view key info and change gaming-related settings. The only real shortcoming is a proper implementation of HGiG. When enabled, the TV still interferes with HDR brightness mapping, so we don't get the effect intended by that standard. Apart from that, the UR8S is very well equipped for both consoles and a powerful PC.
