Panasonic Z85A vs Hisense U7S / U77SE

The Panasonic Z85A is an OLED television, so you can expect great effects in movies right away. And indeed – our tests show that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result that performs well in most demanding HDR scenes, allowing you to enjoy a dynamic and detailed image. However, like every OLED, the Z85A has its limits. In very bright scenes that cover the entire screen – like the final sequence from the movie The Meg – the television reduces brightness to about 400 nits. This is standard behavior for this technology, so if someone plans to watch movies in a brightly lit living room, it's worth keeping this in mind. The coverage of the DCI-P3 color gamut at 98% also deserves a big plus. As a result, the television delivers a wide range of colors that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A provides a solid HDR effect that will satisfy any movie enthusiast.

The Hisense U7S has considerable HDR potential, but it can't use it in every scene. On a test pattern it reaches around 1,100 nits, so the backlight itself is very strong. In our brighter film scenes we measured about 640 to 745 nits. That's still enough for the sun or bright highlights to have a noticeable glow and to show an advantage over SDR material. When the TV needs to illuminate a larger portion of the image, it does quite well.

The problem appears with small lights on a dark background. Each of the 192 zones covers an area much larger than a tiny point on the screen. If the TV were to strongly light such a zone, it would also brighten the surrounding area along with the light. Hisense tries to avoid that and dims the entire zone. Black levels therefore look better, but a small bright object that should draw the eye also loses intensity. That's why in two tougher scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small lights are noticeably muted. The U7S therefore prioritizes maintaining deep blacks, even at the expense of bright details. With this number of zones that's an understandable compromise, but it's worth remembering — the 1,100-nit peak tells us about the backlight's capability, not how brightly the TV will render every element of a film.

Colors

Hisense calls the U7S ULED, but that's a marketing name; the wider color gamut here comes from a PFS phosphor backlight. In our measurements the TV covered about 91% of DCI-P3 and 71% of BT.2020. Those are good results, although it falls short of the best screens on the market. The biggest shortfall is in green — the TV doesn't even reach the DCI-P3 target there, so the most saturated shades will be less intense than they should be. Most colors in HDR films and series, however, still look suitably rich. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

The Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It is rare for a television to be so well-tuned straight out of the box, and the unit we had the opportunity to test really impressed us positively.

However, there were some minor shortcomings. In the SDR signal, we noticed a slight deficiency in red and blue colors, which made the image have a cooler shade than it should. This is particularly evident in the comparative photo. Conversely, in 4K HDR materials, the situation was the opposite – the excess of red made the image seem warmer than the creators intended. In terms of brightness characteristics (gamma) and maintaining the appropriate EOTF curve, it is hard to find fault. There are some minor deviations, but they are so minimal that the average viewer is unlikely to notice them.

It is also worth emphasizing that our observations pertain to a specific unit of the television. Two identical models can differ from each other due to natural production variations. Nevertheless, the unit we had in hand is really solid and deserves praise. Now it's time for our calibration – we'll see if we can squeeze even more from this screen!

The out-of-the-box colors on the Hisense U7S are decent, but there are a few things to improve. In SDR there's a red bias in the white balance, which makes the image too warm and in places slightly pink. You can notice this on faces and on bright, neutral surfaces. Gamma also runs below the reference, so the TV brightens the image, especially in darker areas. That makes shadow details easier to see, but the scene loses some of its depth.

In HDR the white balance is a bit more even, but not completely neutral; midtones lack blue, and the brightest areas lack red. A bigger problem is how brightness is reproduced. The EOTF curve shows that a large portion of midtones is being brightened, so the image looks brighter than the source material intends. Color Checker measurements also perform worse than in SDR: many errors are around 3 to 4, and individual ones reach as high as 8. Colors can therefore look attractive, but they are not always faithful to what we should be seeing. There's room for improvement, and we'll check how much can be corrected with calibration.

The Panasonic Z85A offers truly wide possibilities when it comes to image settings, so we enthusiastically set about calibration. Although we mainly focused on white balance correction, the final effect exceeded our expectations. Both HD and 4K HDR content now present nearly perfect color reproduction, with minimal errors that are difficult to catch with the naked eye. Well-calibrated televisions are rare, and we must admit – it is truly gratifying. Although gamma and EOTF curve did not require drastic adjustments, we managed to further stabilize their characteristics across the entire brightness scale. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The image is precise, colors are natural, and every scene looks exactly as the director intended.

Calibration of the Hisense U7S helped most with SDR content. We managed to even out the white balance, so the previous warm cast is gone and whites and grays look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the image unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors fall below 2. That yields a really well-calibrated picture for regular TV and SDR movies. It didn't go as smoothly in HDR. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the content's brightness a bit on its own. It brightens parts of the image and can dim the brightest elements depending on the scene and the local dimming behavior. Calibration couldn't eliminate this. It shows up in the Color Checker results as well, where many errors remain around 3–4 and individual ones exceed 7. So in SDR the result is very good, but in HDR we have to accept that the TV adds its own interpretation of brightness to the image.

Now that we know how the Panasonic Z85A handles tonal transitions in 4K materials, it's time to look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the selected value – whether low, medium, or high – we were unable to achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this feature to an intermediate level. While it may slightly blur fine details, it at least avoids the problem of losing film grain, which can be crucial for many viewers when watching classic productions.

When it comes to image scaling, the television performs quite well. It is evident that the image is slightly sharpened, and thin lines can sometimes appear somewhat jagged. However, this is standard in most televisions and fortunately, it can be adjusted using the sharpness slider. This gives us full control – we can achieve a more plastic, blurred image or a clearer one, though more "harsh" and artificially sharp. It all depends on the user’s preferences and the type of content we are watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution materials.

The handling of lower-quality material on the Hisense U7S is fairly mediocre. The Pentonic 700 chipset used here doesn't cope well with the effects of heavy compression. The menu includes a "Smooth & Gradient" picture option, but its performance leaves much to be desired. At the low setting it's hard to notice any improvement in tonal transitions, although at least the image isn't degraded. The medium and high settings still don't remove visible banding between shades and begin to smear details; in our test clips even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you use this feature, we'd stick with the low setting. Its current behavior needs refinement, but that's mainly down to the processor used. Upscaling to 4K performs much better. Lower-resolution footage gains clarity, edges are well reconstructed, and fine elements look crisp. That doesn't mean it can recover details that weren't in the recording, but the TV makes good use of what it gets from the source. Another plus is that it doesn't crop the image edges, even with an SD signal.

The Panasonic Z85A has a 120 Hz panel, which will surely please both gamers and sports fans. Sure, it's not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the image is stable and clear, and during fast action, there's no sign of any motion blur. The same goes for sports – a quick run by a soccer player or a dynamic car maneuver looks smooth and natural. The TV also has an "Intelligent Frame Creation" feature, which is a motion smoother. There are two sliders – one for reducing motion blur and the other for motion smoothness. With these, you can adjust the picture to your personal preferences – whether you prefer a more cinematic effect with gentle transitions between frames or a maximally smooth image perfect for watching sports.

Motion handling on the Hisense U7S is pretty good thanks to the 144 Hz refresh rate. For movies we also have a motion smoothing feature that lets you adjust judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if abrupt camera shifts bother you. In sports and games the high refresh rate is also useful, but unfortunately it doesn't solve this panel's biggest problem.

The culprit is pixel response time. Fast-moving objects leave long, noticeable trails, as our UFO test shows. It's worst on dark backgrounds, where the trail behind the object is especially pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

Panasonic is mainly associated with home cinema televisions, but the Z85A shows that it can also enter the gaming world with a really strong punch. This is equipment that can easily be called a gaming beast - it has everything needed for comfortable gameplay.

Even though we only have two HDMI 2.1 ports, both operate at full bandwidth, so we can easily connect both a next-gen console and a gaming PC. All key features are supported: ALLM automatically switches the TV to game mode, VRR ensures smooth images without stuttering and tearing, and with properly implemented HGIG and Dolby Vision, HDR games look really good - colors are vivid, details clear, and dark scenes readable. There is also a Game Bar in the form of a clear, circular menu. It may not look as impressive as with the competition, but it is intuitive and contains all the most important settings that we would like to have at hand during gaming.

In summary - the Panasonic Z85A is equipment that really surprises with its gaming capabilities. It is a television where both console gamers and PC gamers will feel at home. It's smooth, dynamic, and simply good.

The Hisense U7S has a lot to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz at Full HD, 1440p, and 4K, so modern consoles’ capabilities are well used. When connected to a PC you can use 144 Hz at 4K or switch the resolution to Full HD and run 240 Hz. So there’s a wide choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate does not eliminate. VRR and ALLM are also present. The first helps prevent tearing when frame rates in a game change. The second automatically switches the TV into game mode, so you don’t have to dig through the menu each time. VRR works from 48 to 240 Hz, with the highest refresh rate available in Full HD. Xbox users can also play in Dolby Vision, including at 120 Hz. Importantly, this format does not introduce significant input lag here. The Game Bar also looks very good. It’s easy to read, visually appealing, and lets you quickly check what signal the TV is receiving. There are also handy gaming settings at your fingertips, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the entire menu.

Our biggest complaints concern HGiG. Hisense continues to do its own tone mapping, which makes setting HDR on the console confusing. You adjust a checkerboard test pattern and the TV continuously adapts how it looks. As a result, the moment the pattern disappears does not correctly indicate the screen’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR peak brightness on the console to about 900 to 1000 nits, rather than relying on the configurator.
