Samsung Q6F (IPS) vs Hisense U7S Pro

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even talk about any "high dynamic range" or HDR effect. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another issue is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire screen to artificially improve the black levels. This results in the image becoming even darker, with brightness sometimes dropping below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not of the highest quality, as the coverage of the DCI-P3 colour gamut does not exceed 90%. Because of this, colours in HDR content may simply appear unsaturated.

Let's start with the fact that the U7S Pro is an impressively bright television – in calibrated mode, our measurement equipment indicated a staggering 2200 nits of peak brightness! This is an absolutely remarkable result, considering this model is positioned rather as a mid-range option.

However, as we know, peak brightness on test patterns is one thing, and actual movie scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. Admittedly, in the most demanding moments, the television can still exceed the 1000-nit barrier – which is still an excellent result, perfectly aligned with the mastering standards of most HDR films – but the real challenge comes from aggressively tuned local dimming algorithms. Because of these, small bright details, such as stars or the moon in the night sky, become noticeably dimmed. The television tries to maintain deep blacks at all costs, which is of course understandable, but unfortunately, this comes at the expense of the dynamics and brilliance of the HDR effect itself.

It's worth praising the colour reproduction. The new U7S Pro is a QLED type construction that provides a very wide coverage of the colour palette. Unlike last year's model (U7Q Pro), this year's variant is a "true" QLED, not a solution based on a PFS filter. As a result, color saturation has significantly increased, and the coverage of the most demanding BT.2020 space has exceeded the 81% barrier.

We tested the television in Filmmaker mode, which showed us two completely different sides of this model. Looking at SDR content, we were honestly shocked at how good this television looks straight out of the box. It was really hard to pick on anything here. Despite a slight 'messiness' in white balance and some slightly brightened details in the blacks (which directly stems from the IPS panel construction), colour errors hovered around the '2' level. This is not only a surprisingly good result but rather phenomenal, considering the price of the device.

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

We've tested the U7S Pro model – as we always do – in the best factory-tuned picture mode, which is Filmmaker Mode. We can assess the displayed colours in two ways. The most disappointing was the profile intended for watching SDR content, that is, traditional television, YouTube, and other less demanding materials. The picture was clearly too yellow, which was a direct consequence of a poorly set white balance. As our graphs show, there is a huge deficiency of the blue component here, which drastically affected the overall colour temperature. This is clearly evident on the ColorChecker charts and the colour palette graphs, where most samples leaned towards yellow. Fortunately, the factory HDR mode performed much better – there the colour errors hovered around a Delta E value of 3, which is already a really solid result.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at a level of "1" are something typically seen in devices costing several thousand dollars. In this respect, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our intervention in HDR mode did not yield a noticeable improvement. The television, due to its weak 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 primarily exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

We do know, however, that the company Hisense is capable of much more – as previous generations have proven – which is why we simply couldn’t leave the factory flaws of the U7S Pro model unaddressed in everyday content. As always in such cases, we had the television undergo professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and compensating for deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally clean, and skin tones gained the proper, healthy hue. Importantly, the calibration not only tamed the capricious SDR mode but also maximised the potential of the panel, reducing average colour reproduction errors to values nearly imperceptible to the human eye. The only thing we need to criticise after the whole process is the very nature of the Mini-LED backlighting and its specific interaction with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlighting doesn’t always work perfectly with the creator’s intent – depending on the scene being watched, the curve can noticeably run either above or below the reference, occasionally disrupting the ideal dynamic of HDR images.

Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good, even for such an inexpensive QLED model. The only downside is when watching very low-resolution materials like 576p (typical for old DVD players) – the image may appear slightly cropped. This is because the TV does not allow the option to turn off the Overscan feature, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, or the attempt to smooth the image of unwanted artifacts. Here, the TV completely fails. Although in the menu we find a feature called "Noise Reduction," it does not produce any noticeable results regardless of the slider setting. The only thing it seems to do is introduce undesirable errors into the image. Despite its presence in the system, we definitely do not recommend using it.

The digital processing of lower quality signals is at a very high level here, all thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling also performs well, which is the TV's ability to enhance lower resolution signals to 4K. We did not notice any unnatural, sharp contours on the screen, and our test image featuring a model simply looked appealing.

The 60 Hz panel in the Samsung Q6F is standard in this price range, making it a rather average model for dynamic sports or gaming. However, when it comes to movies, the TV performs quite well thanks to its smoothing feature. The "Motion Vibration Reduction" option allows you to adjust the motion smoothness to your own preferences – from preserving a cinematic feel to full smoothness.

Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz in 4K, and in gaming mode, it can even reach 330 Hz at Full HD resolution. However, it is important to remember that these highest numbers do not have much significance in everyday usage, as most content supports a maximum of 120 Hz (e.g., when playing on a console). Nevertheless, the TV handles motion quite well and performs really well for an LCD construction.

It's hard to fault the fluidity. In the menu, we find a motion smoother called "Motion Enhancement," which has two sliders: motion blur reduction and judder reduction. They allow for manual configuration of the smoother, which works well in both movies and sports, effectively enhancing the raw TV signal.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does include features like ALLM (Auto Low Latency Mode) and VRR frame syncing for consoles, that's pretty much where the list of advantages ends. Beyond these basics, the television offers nothing more that could satisfy those who spend a lot of time in front of a console. It's a real shame that a useful tool like Game Bar, which allows for quick control of game parameters in higher-end Samsung models, is missing here. In terms of gaming, this is an absolutely basic model and it will only suit 'casual' gamers.

If you're planning to connect a console or PC to the U7S Pro, you'll be more than pleased – this TV is great gear for gamers. Hisense hasn't held back, featuring 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. So you don't have to juggle cables, as each port will handle the full suite of features. We have an automatic game mode (ALLM) and VRR, which operates over a wide range from 48 Hz to a whopping 330 Hz. Of course, that 330 Hz is currently just a gimmick for owners of powerful PCs, as consoles will cap at 120 Hz, but it's good to have that headroom for the future. The Game Bar also works really well when gaming. It's a handy menu bar for gamers, where you can quickly change the picture mode, turn on a crosshair in the middle of the screen, and even switch the display aspect ratio to ultra-wide, which PC simulation fans will appreciate. The only downside worth noting is the incorrect implementation of the HGiG format in games. The issue is that the TV ignores instructions from the console regarding the image generated in HDR10 and constantly butts in, trying to "enhance" the image in its own way. This makes proper HDR configuration in the console menu (where brightness is set on the logo/checkerboard) a bit more challenging.
