Samsung Q6F (IPS) vs Hisense UR8S

The Samsung Q6F is, unfortunately, a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is a value that is decidedly too low to even talk about any effect of “high dynamic range,” or HDR. In practice, it’s better to stick to content in SDR format, which simply looks more predictable on this television. Another problem is the global dimming technique – in scenes with a lot of black, the television drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and the brightness can drop below 100 nits. The only consolation is supposed to be the QLED technology, but even here it is average. The layer of quantum dots used is not of the highest quality, as the coverage of the DCI-P3 colour palette does not exceed 90%. As a result, the colours in HDR content may simply appear under-saturated.

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.

We tested the television in Filmmaker mode, which showed us two completely different facets of this model. Looking at SDR content, we were genuinely shocked at how good this television looks straight out of the box. It was really difficult to find fault with anything here. Despite a slight 'muddiness' in the white balance or somewhat brightened details in the blacks (which directly stem from the design of the IPS panel), the colour errors hovered around a level of '2'. This result is not only surprisingly good but downright amazing, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colours after switching to HDR mode was a very unpleasant surprise. The errors in colour reproduction and palette were so enormous that our charts literally ran out of scale. Of course, since Samsung even in such an affordable model offers very extensive calibration options, we decided to approach the issue professionally and see what could be done during calibration.

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.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at the '1' level are something generally seen in devices costing several thousand pounds. In this regard, the Q6F is really an excellent screen for everyday television, less demanding series or films. Unfortunately, our intervention in the HDR mode did not bring a noticeable improvement. The television, due to its poor blacks and low coverage of a wide colour gamut, still has significant issues with proper colour saturation, especially reds. This is an example of a device where HDR exists mainly as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

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.

Q6F performs very well in upscaling lower-resolution content to native 4K. The scaling here is surprisingly good, even for such an inexpensive television from the QLED series. The only downside is the situation where we are watching very low-resolution materials, such as 576p (typical for old DVD players) – in which case the image may be slightly cropped. This is due to the fact that the television does not allow the Overscan function to be turned off, which is a typical issue with Samsung devices.

The situation is completely different when it comes to digital processing, specifically the attempt to smooth the image of unwanted artifacts. Here the television completely fails. Although there is a function in the menu called "Noise Reduction," it yields no visible results regardless of the slider setting. The only thing it manages to do is introduce undesired errors in the image. Despite its presence in the system, we definitely do not recommend using it.

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.

The 60 Hz panel in the Samsung Q6F is standard for this price range, making it rather average for dynamic sports or gaming. However, when it comes to films, the television performs quite well thanks to the motion smoothing feature. The "Motion Reduction" option allows you to adjust the smoothness of movement to your own preferences – from maintaining a cinematic character to complete fluidity.

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.

We're not going to beat around the bush – the Q6F is not a television designed for gamers. Although it features additions like ALLM (automatic low latency mode) and VRR frame synchronisation for consoles, the list of advantages basically ends there. Aside from these basics, the television offers nothing more that would satisfy those who spend a lot of time in front of a console. It’s a great shame that such a useful tool as Game Bar, which allows for quick control of game parameters in Samsung's higher models, is missing here. In terms of gaming, this model is absolutely basic and is only suitable for "casual" gamers.

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.
