Hisense U7S Pro vs TCL P7L / P79L

Let’s start with the fact that the U7S Pro is an impressively bright TV — in calibrated mode our measurement equipment showed a staggering 2200 nits of peak brightness!

As we know, peak brightness on test patterns is one thing, and actual film scenes are another. Unfortunately, in real video material the backlight output drops noticeably. The TV can still exceed the 1000-nit mark in the most demanding moments — which is still a great result and fits the mastering standards of most HDR films — but the real challenge lies in the aggressively tuned local dimming algorithms. Because of them, small, bright details like stars or the moon in a night sky are noticeably dimmed. The TV tries at all costs to maintain deep black, which is understandable, but unfortunately this comes at the expense of HDR’s dynamic range and brilliance.

The color reproduction is worth praising. The new U7S Pro is a QLED design that provides very wide color gamut coverage. 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 increased noticeably, and coverage of the most demanding BT.2020 color space has topped 81%.

The biggest limitation of the TCL P7L in HDR is simply brightness. The TV doesn't have a large luminance headroom, so strong highlights, sunlight, or small light sources can't clearly "pop" out of the image. As a result, even well-produced HDR material looks fairly restrained and in terms of dynamic range is closer to good SDR than to what brighter models show. That doesn't mean the P7L can't handle HDR at all — the issue is mainly a lack of sufficient backlight power.

Looking at color, the situation is a bit better. The TV covers about 91% of the DCI-P3 gamut and about 68% of the wider BT.2020 color space, so for its price class the color range is quite decent. TCL markets this model as QLED, though the nature of the solution used is closer to a PFS phosphor-based backlight than a classic quantum-dot layer. What matters most to viewers, however, is the result: more saturated colors are available.

We tested the U7S Pro, as we always do, in the best factory-tuned picture mode, Filmmaker Mode. The colors can be judged in two ways. The most disappointing was the profile intended for watching SDR content, i.e. traditional broadcast TV, YouTube, and other less demanding material. The image there was clearly yellowish, which turned out to be a direct consequence of a poorly set white balance. As our charts show, there's a large deficiency in the blue component, which drastically affected the overall color temperature. You can see this clearly on the ColorChecker charts and on the color gamut graphs themselves, where most samples shifted toward yellow. Fortunately, the factory HDR mode performed much better. There, color errors hovered around a Delta E of 3, which is a solid result.

In Film mode the TCL P7L performs fairly well without major adjustments, especially with typical SDR material. The white balance is relatively even, although as brightness increases there is a slight rise in red and blue and a bit of a shortage of green. This does not produce a strongly noticeable tint and most colors remain close to their reference points. The ColorChecker confirms this, with a large portion of errors falling below a level that would notably bother viewers during normal watching. We have more concerns about the gamma response. In the darkest parts of the image the TV runs it noticeably above the reference, so some shadow detail can be a little too dimmed. The curve then settles and for much of the range it is close to the intended target. As a result SDR generally looks natural, but in dark scenes the P7L can lose some subtlety. In HDR the factory setting is less precise. As brightness increases an excess of blue becomes more pronounced, making the image look cooler than it should. The number of larger color deviations also grows, particularly in brighter hues. The EOTF curve itself is handled fairly conservatively, with the TV showing the image darker than the reference over a large portion of the range. For a budget model, however, the factory Film mode settings are not bad.

We know, however, that Hisense is capable of much more, as previous generations have shown, so we simply couldn't leave the U7S Pro's factory flaws in everyday content as they were. As always in such cases, we had the TV professionally calibrated. The result? The process brought a massive change. After manually correcting the white balance and filling in the missing blue component, the annoying yellow cast vanished as if it had been wiped away. Whites became naturally clean, and skin tones gained a proper, healthy hue. Importantly, the calibration not only tamed the finicky SDR mode but also squeezed the maximum potential out of the panel, reducing average color reproduction errors to levels almost imperceptible to the human eye. The only thing we still have to fault after the whole process is the nature of Mini-LED backlighting and its specific interaction with the HDR signal. Aggressively tuned local dimming algorithms quite strongly interfere with the EOTF luminance curve. As a result, the backlight doesn't always align with the creator's intent — depending on the scene, the curve can run noticeably above or below the reference, which in places disrupts the ideal dynamics of the HDR picture.

After calibration, the TCL P7L can deliver a really pleasant picture, especially with classic SDR material. We managed to very effectively even out the white balance, and the gamma curve now tracks close to the target value of 2.4. You can also see this in the color measurements, as most errors dropped noticeably, and in everyday viewing it's hard to find any strongly visible inaccuracies. Movies, series, YouTube, or regular TV therefore look more natural, without unnecessary warming or a cool cast. For a model in this price range, the result in SDR is really very good.

With HDR the situation gets more complicated. Calibration helped improve the white balance and tidy up some deviations, but here the panel's limitations become increasingly apparent. The P7L has relatively low brightness and can't maintain appropriate luminance for more saturated colors, so some errors remain even after careful tuning. In other words, settings can improve how the TV interprets the signal, but they can't overcome its physical capabilities. That's why calibration makes the most sense for this model primarily with SDR.

The digital processing of lower-quality signals is top-notch here, thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. Upscaling, the TV's ability to pull lower-resolution content up to 4K, also performs well. We didn't notice any unnatural, sharp contours on screen, and our test image with the model simply looked attractive.

In this regard the TCL P7L performs surprisingly well, especially for such an inexpensive TV. The tonal transition smoothing feature, which in many budget models does little or almost nothing, actually manages to improve the picture here. It doesn't remove all banding completely, but it can noticeably reduce posterization and make trickier gradients look more natural. At this price point that's a genuinely pleasant surprise.

Upscaling itself also performs well. Lower-resolution material is scaled correctly, without excessive sharpening or adding artificial outlines around objects. Of course the P7L won't turn a very poor source into 4K-quality footage, but for regular TV the result is simply solid. For a model in this class there is little to criticize.

The Hisense U7S Pro uses a panel with a maximum 165 Hz refresh rate at 4K, and in game mode it can even reach 330 Hz at Full HD. However, it's worth remembering that those highest numbers don't matter much in everyday use, because most content still supports at most 120 Hz (for example when playing on a console). Even so, the TV handles motion quite well and performs well for an LCD design.

There's little to fault about the smoothness itself. In the menu you'll find a motion smoothing feature called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. They allow manual adjustment of the smoother, which works well for both movies and sports, effectively improving the raw TV signal.

The TCL P7L uses a panel with a native 60 Hz refresh rate at 4K resolution, and that's how it should be treated in everyday use. For movies the TV mainly offers frame interpolation, so it can smooth motion and reduce the typical judder, but it does not deliver the smoothness of true 120 Hz panels.

If you plan to connect a console or PC to the U7S Pro, you'll be more than happy – this TV is great for gamers. Hisense spared no expense and put in four HDMI 2.1 ports with full 48 Gbps bandwidth. So you won't have to juggle cables, since every port supports the full feature set. There's automatic low-latency mode (ALLM) and VRR, which works across a wide range from 48 Hz up to a cosmic 330 Hz. Of course that 330 Hz is for now a gimmick for owners of powerful PCs, because consoles are capped at 120 Hz anyway, but it's good to have that headroom for the future. The Game Bar is also really useful while gaming. It's a handy in-game menu where, without leaving the TV's main settings, you can quickly change the picture mode, enable a crosshair in the center of the screen, or even switch to an ultra-wide aspect ratio, which PC sim fans will appreciate. The only downside worth knowing about is the incorrect implementation of HGiG in games. The TV ignores the console's instructions for HDR10 output and keeps forcefully altering the image, trying to "improve" it its own way. Because of that, properly configuring HDR in the console menu (where you set brightness using the logo/checkerboard pattern) is a bit more difficult.

For such an inexpensive TV, the P7L has quite a lot to offer gamers. It has ALLM, VRR, Dolby Vision for gaming, and TCL adds its Game Bar, which lets you quickly view key information or change some settings without leaving the game. Not everything is perfect, though, because HGiG doesn't work here as it should, but at this price point it's hard to complain much about the feature set. The most interesting thing starts when you give up on 4K. At that resolution the TV runs at a maximum of 60 Hz, but at 1440p and 1080p it can already display at 120 Hz. And that's not just a spec-sheet curiosity. In fast-paced games that support that frame rate you can really notice the difference in smoothness, so if you care more about smoother motion than maximum image sharpness, that mode can make a lot of sense. Of course that doesn't make the P7L a true 120 Hz TV. Even so, it's precisely those extra modes that make the P7L perform really well for gaming.
