Hisense U7Q vs Samsung Q6F (IPS)

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good effect when it comes to brightness and overall HDR quality. Unfortunately – here we have to disappoint you a bit.

The U7Q is quite a bright TV – in optimal conditions, it can reach around 800 nits, which indeed impresses on some screens, especially in scenes like those from the movie The Meg. Bright segments can really shine, and the HDR effect is noticeable. The problem arises when very small, bright elements appear on a dark background – for example, in Sicario 2 or in the second scene of the movie Life of Pi. In such moments, the dimming algorithms operate too aggressively. Yes, the blacks look great then, but the brightest points can almost completely fade, causing the HDR effect to disappear and details to be barely visible. That's just the nature of this technology in this price segment.

As a consolation, it's worth adding that the U7Q is advertised as a QLED TV (in practice, a PFS layer is used, which works very similarly), and it is indeed capable of displaying a wide color palette – with DCI-P3 coverage at around 94%, that's a very good result for this class.

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 speak of any "high dynamic range" effect, or HDR. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another problem is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and brightness can drop below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not top-notch, as the coverage of the DCI-P3 color gamut does not exceed 90%. As a result, colors in HDR content may just seem under-saturated.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This mode is supposed to provide the most "filmic" experience and fidelity to the creators' intent – right out of the box. Unfortunately, even this professionally sounding name does not guarantee a perfect picture.

In our unit, the problem lay in a poorly set white balance. Both in HD and 4K content, the image had too much blue and red, giving the screen a slightly pinkish hue. It didn't look terrible, but it was noticeable – especially in bright scenes and white backgrounds. This alone could have been forgiven, but the biggest issue is the management of brightness in HDR content. The EOTF curve from the measurements confirms what we saw earlier during the scene tests: the television often dims the smallest bright elements too much, causing them to almost disappear, or conversely – excessively brightens the brightest ones, affecting the naturalness of the image.

We tested the television in Filmmaker mode, which showed us two completely different faces of this model. Looking at SDR content, we were honestly shocked at how good this TV looks straight out of the box. It was really hard to nitpick anything here. Despite a slight “haze” in the white balance or somewhat brightened details in the blacks (which directly results from the IPS panel's design), color errors hovered around the “2” level. This is surprisingly good, even outstanding, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colors after switching to HDR mode was a very unpleasant surprise. The errors in color reproduction and palette were so huge that our charts literally ran out of scale. Of course, since Samsung even in such an inexpensive model offers very advanced calibration possibilities, we decided to approach the subject professionally and check what could be done about it during calibration.

Thanks to specialized tools, we managed to correct the color quality in SDR content to nearly perfection. In materials with lower dynamics, delta E errors dropped below 0.5, which can be considered an almost reference result. The image on television, YouTube, or classic Full HD looks really good after calibration. Well, but where couldn’t we improve the image so easily? Primarily, it concerns HDR quality content. While we managed to somewhat "tame" the white balance and eliminate pink hues in most scenes, unfortunately, we did not have full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of overly strong dimming or brightening of details that the calibration simply couldn't eliminate. And although the overall reception of the content is much better, it must be taken into account that the U7Q will always have something to say at the end "but."

After our calibration, the colors in SDR mode looked even better – the result is quite surprising, as color errors at level "1" are something usually seen in devices costing several thousand dollars. In this regard, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our interference in HDR mode did not bring about a noticeable improvement. The television, due to its poor black levels and low coverage of a wide color gamut, still has significant problems with proper color saturation, especially red. This is an example of a device where HDR mainly exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those that have limited source quality. The U7Q is equipped with a feature called “Smooth and Gradient Image,” but unfortunately… it works very poorly. In the “Low” option, the effects are practically unnoticeable, and other settings smooth out details but do not improve tonal transitions. The only plus is that the feature does not interfere with film grain, so it does not ruin the natural structure of the image.

Fortunately, content scaling performs quite well. The image is not overly sharpened, there is no artificial clarity – and although it is known that this is not the level of high-end televisions, the U7Q handles displaying really old content in a completely acceptable manner without any problem.

The Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good here, even for such a budget TV from the QLED series. The only downside is when we watch very low-resolution material, like 576p (typical for old DVD players) – then the image may be slightly cropped. This is because the TV does not allow for the Overscan feature to be turned off, which is a common issue with Samsung devices.

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

U7Q is truly a fast television, similar to its more powerful version "PRO". At a resolution of 4K, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it’s worth appreciating – this is a rare feature in this price segment. Right from the start, it’s clear that U7Q was created with dynamic content in mind, such as games or sports. In films, we are not left "out in the cold" either – U7Q offers the "Ultra Motion Smoothness" feature, where using two sliders you can adjust whether you want a smoother, theatrical image, or something closer to a cinematic style with a visible frame. It’s good that, like with most manufacturers, we have a choice here and can adjust it to our own preferences.

The 60 Hz panel in the Samsung Q6F is the standard in this price range, which makes it a rather average model for dynamic sports or gaming. However, in the case of movies, the TV performs quite well thanks to the smoothing feature. The "Motion Smoothing" option allows you to adjust the fluidity of motion to your own preferences – from maintaining a cinematic feel to full fluidity.

The Hisense U7Q is a TV designed for gamers – and you can see that right away based on its gaming capabilities. It has practically everything you could wish for: variable refresh rate (VRR) – check, automatic game mode (ALLM) – also check, and high refresh rates of up to 240 Hz in Full HD, as well as support for various resolutions, not just 4K. It's truly a great set of features that makes the U7Q excel in both fast-paced shooters on consoles and more demanding titles on PC. Of course – like in most Hisense models – it lacks a proper implementation of the HGiG function. That's a shame because HGiG allows you to adjust the brightness of the console to the specific TV, which in practice makes displaying HDR games according to the creators' intentions much easier. Without this, you simply have to reckon with certain limitations in the final HDR image in games.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does have features like ALLM (Auto Low Latency Mode) and VRR frame synchronization for consoles, the list of benefits pretty much ends there. Besides these basics, the TV offers nothing more that might satisfy those who spend a lot of time in front of a console. It’s a real shame that such a useful tool as Game Bar is missing here, which in Samsung’s higher models allows for quick control of game parameters. In terms of gaming, this is an absolutely basic model and is only suitable for "casual" gamers.
