Hisense U7S Pro vs LG MRGB85B

Let's start with the fact that the U7S Pro is an impressively bright TV. In calibrated mode our test equipment recorded a staggering 2200 nits of peak brightness. That's an excellent result, especially given that this model is positioned more as a mid-range set.

As we know, peak brightness on test patterns is one thing, and real film scenes are another. Unfortunately, in real-world footage the backlight output drops noticeably. In the most demanding moments the TV can still exceed 1000 nits, which is still a great result and sits well within the HDR mastering standards for most films, but the real challenge comes from 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 seems determined to preserve deep blacks, which is understandable, but sadly this comes at the expense of dynamic range and the overall HDR punch.

Colour reproduction is worth praising. The new U7S Pro is a QLED design that provides very wide colour gamut coverage. Unlike last year's model (U7Q Pro), this year's variant is a genuine QLED rather than a solution based on a PFS filter. As a result, colour saturation has clearly increased, and coverage of the demanding BT.2020 colour space has exceeded 81%.

LG MRGB85 offers moderate brightness. On test patterns it reaches around 700 nits, which is a decent result in itself. In real movie scenes, however, values are lower and most often fall in the 400 to 600 nits range. Bright, wide shots look best. In scenes with large areas of black the TV noticeably reduces luminance, attempting to keep contrast as high as possible. The HDR effect is therefore visible, but it is far from the level offered by more advanced Mini-LED designs. Particularly in darker parts of films, the limitations of the edge-lit backlight and imprecise local dimming become apparent again.

HDR colours

A much stronger suit of the MRGB85 is its colour. The TV covers around 95% of the DCI-P3 colour space and 74% of BT.2020, so HDR content can look vivid and impressive. Colours are well saturated, and the difference compared with basic LCD TVs is clearly noticeable. It is worth noting, however, that this is not a classic RGB backlight, where each of the three primary colours is generated by a separate diode. Red is produced by a PFS phosphor, which expands the palette and achieves more saturated red tones. This solution performs well for colour reproduction, but it does not change the limitations of the local dimming. The diodes are not driven independently in the way the series name might suggest... so it turns out that Mini RGB is not the same as Mini-LED RGB!

We tested the U7S Pro, as we always do, in the best factory-tuned picture mode, Filmmaker Mode. The displayed colours can be judged in two ways. The most disappointing was the profile intended for SDR viewing, i.e. classic TV, YouTube and other less demanding content. The image there had a distinct yellow cast, which proved to be a direct result of an incorrectly set white balance. As our charts show, this involved a huge deficiency of the blue component, which drastically affected the overall colour temperature. You can see this clearly on the ColorChecker charts and on the colour palette graphs themselves, where most samples drifted towards yellow. Fortunately, the factory HDR mode performed much better; there the colour errors hovered around a Delta E of 3, which is a really solid result.

We tested the TV in Filmmaker Mode because, of the available presets, it produced the image closest to reference. The out-of-the-box colour reproduction wasn’t perfect, though. The biggest deviations were in the white balance, with too much red and not enough blue in the image, so the overall picture shifted noticeably towards warmer tones. Whites took on a slightly yellowish tint, and skin tones and bright areas didn’t always look natural. It wasn’t a fault that ruined the viewing experience, but in a direct comparison with the same panel after calibration the difference was clearly visible.

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.

Calibration primarily corrected the white balance and removed the previously noticeable warm cast. After the correction, whites no longer had a yellow tint and colours became more neutral and natural. The biggest improvement was seen in SDR material, where the picture looked even and much closer to the reference. A similar effect was achieved in HDR. After calibration the image became more controlled, although not all of the TV’s limitations could be eliminated. The main issue remained intense reds, which were not always reproduced with sufficient precision. In practice the MRGB85 handles everyday SDR content very well, but in more demanding HDR material its limitations are still clearly visible.

The digital processing of lower-quality signals is at a very high level here, and that's all thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling itself also performs well, meaning the TV's ability to upscale lower-resolution signals to 4K is impressive. We didn't notice any unnatural, overly sharp contours on the screen, and our test image of the model simply looked attractive.

Upscaling and digital image processing perform quite well in the LG MRGB85. The Alpha 8 AI 4K Gen7 processor efficiently upscales lower-resolution material, and you can easily turn off overscan regardless of the source. The TV also handles compression artefacts well. The "Smooth Gradation" function can effectively reduce visible banding and tonal unevenness, but it isn't always precise. At higher settings it can also smooth out fine details, such as the texture of materials. A plus is that it doesn't remove film grain. The safest option is the "Low" or "Medium" setting, which offers the best compromise between artefact reduction and preserving detail.

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz at 4K, and in gaming mode it can even hit 330 Hz at Full HD. However, it's worth remembering that these top figures don't mean much in everyday use, because most content still runs at a maximum of 120 Hz (for example when playing on a console). Even so, the TV handles motion quite well and performs respectably for an LCD design.

There isn't much to fault when it comes to smoothness. In the menu you'll find a motion smoothing feature called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. They let you manually tune the smoothing, which works well for both films and sport, effectively improving the raw TV signal.

The LG MRGB85 is fitted with a VA panel with a native 144 Hz refresh rate, so its motion handling is very good. The TV easily handles 120 Hz content from consoles and higher refresh rates when connected to a PC. That matters not only for gaming but also when watching sport, where camera motion is noticeably smoother than on basic 60 Hz panels. There’s also the TruMotion system, which lets you set the level of motion smoothing yourself. You can keep a more cinematic motion or increase smoothness, which works well for live sports and TV programmes. The adjustment range is wide, so you can easily tailor the motion smoothing to your own preferences.

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.

When it comes to gaming, the LG MRGB85 performs by far the best. The manufacturer hasn’t skimped on the kit and has essentially carried over the full suite of features from pricier TVs into this model. You get three HDMI 2.1 ports with full 48 Gb/s bandwidth. Each supports 4K 120 Hz from a console, and when connected to a PC also 4K 144 Hz. So you don’t need to worry which port to plug your console or PC into, as they all offer the same set of capabilities.

On board you’ll also find VRR, AMD FreeSync Premium, NVIDIA G-Sync Compatible, ALLM and HGiG. Dolby Vision Gaming is included too, allowing supported games to use high refresh rates and dynamic HDR simultaneously on Xbox. Rounding it off is Game Optimizer, a handy in-game menu. Without leaving the game you can change the picture profile, brighten shadow detail or check the current frame rate. In terms of gaming features, the MRGB85 therefore offers almost the same as significantly more expensive LG models.
