Philips PUS8209 vs Hisense U7S / U77SE

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true effect of HDR. In practice, the image resembles standard SDR more, so it’s hard to speak of deeper visual experiences. On the positive side, the colour gamut coverage is commendable – 91.4% DCI-P3 is a score that will be sufficient for most films. It must also be said that the image is stable and there are no issues with sudden changes in brightness or colours. Overall, HDR on this television is more of a formality than an actual added value. If we are looking for genuine HDR thrills, this model may not meet expectations.

The Hisense U7S has considerable potential for HDR display, but it cannot exploit that potential 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 is still plenty for the sun or bright highlights to have a clear bloom and to show an advantage over SDR material. When the TV needs to brighten a larger portion of the image, it handles it fairly well.

The problem appears with small highlights 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 light that whole zone strongly, it would also brighten the area around the highlight. Hisense tries to avoid that and dims the entire zone. This makes blacks look better, but a small bright object that should attract the eye also loses intensity. That is why in two more demanding scenes we recorded only 297 and 154 nits. The difference is large: in one shot HDR can impress, and in the next small highlights are noticeably muted. The U7S therefore prioritises preserving deep blacks, even at the expense of bright details. With that number of zones it is an understandable compromise, but worth bearing in mind — the peak 1,100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense describes the U7S as ULED, but that is a marketing name, and it is a PFS phosphor backlight that expands the colour palette here. In our measurements the TV covered about 91% of the DCI-P3 colour space and 71% of BT.2020. Those are good results, though they fall short of the best screens on the market. The largest shortfall is in green — the TV does not even reach the DCI-P3 boundary here, so the most intense shades will be less saturated than they should be. Most colours in HDR films and series still look suitably vibrant. A positive is the repeatability of the results. Gamut coverage on test patterns and in film scenes is practically identical.

Philips PUS8209 offers many picture modes, but the best of them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear problems. In the case of HD content, the white balance is characterised by a strong dominance of red, which causes the picture to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the mid-tones, has serious issues at the beginning and end of the curve. Drops in the shadows cause a loss of detail in the dark areas, and blowouts in the bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an artificial enhancement effect, reminiscent of unnatural retail settings. Such an image looks unattractive and inconsistent with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference chart, causing the image to appear too dark, robbing the depth and detail of HDR content.

Against this backdrop, errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively impacts the overall image quality. The Filmmaker mode, although the best among the available options, requires substantial corrections to fully convey the director's vision.

Out-of-the-box colours on the Hisense U7S are decent, but there are a few areas to improve. In SDR there is a red bias in the white balance, which makes the picture too warm and, in places, slightly pink. You can notice this on faces and on bright, neutral surfaces. The gamma also runs below the target, so the TV brightens the image, particularly in darker areas. That makes shadow detail easier to see, but the scene loses some of its depth.

In HDR the white balance is somewhat more even, but not entirely neutral, with a shortage of blue in the mid-tones and a lack of red in the brightest parts. A bigger issue is how brightness is rendered. The EOTF curve shows a large portion of the mid-tones being lifted, causing the picture to look brighter than the source intends. Color Checker measurements are also weaker than in SDR: many errors are around 3 to 4, and some reach as high as 8. Colours can therefore look attractive, but they are not always faithful to what we should see. There is room for improvement here and we will see how much can be corrected through calibration.

After calibration, the white balance for HD and 4K content has significantly improved. Although we have not achieved a perfectly flat characteristic, the effect is definitely better than before. The picture on the television no longer appears artificially warm or excessively cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted – the biggest issues at the beginning and end of the graph have been mitigated. The EOTF curve, responsible for brightness in 4K HDR material, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be noticed due to average coverage of the wide colour gamut, which is a limitation of the equipment itself. Nevertheless, the final effect is clearly better than before calibration – the image looks more natural and approaches the expectations of the Filmmaker mode.

Calibration of the Hisense U7S brought the biggest improvements with SDR material. We managed to even out the white balance, so the previous warm tint has gone and whites and greys now look neutral. Gamma is also now very close to the reference, and the TV no longer brightens the picture unnecessarily, so darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. That means the picture is very well set up for watching regular TV and SDR films. It wasn't as smooth in HDR. There is no effective way to correct the EOTF curve, so the TV still interprets a film's brightness somewhat on its own. It brightens parts of the picture and can dim the brightest elements depending on the scene and the behaviour of the local dimming. Calibration could not eliminate this. This is also reflected in the Color Checker results, where many errors remain around 3–4 and a few exceed 7. So the result in SDR is really very good, but in HDR we must accept that the TV adds its own interpretation of brightness to the image.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, this comes at a cost – the feature simultaneously smooths out details such as the texture of materials. On the positive side, it is worth noting that the operation of this option does not negatively affect film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, one can sometimes notice issues with aliasing on certain elements, such as branches or fine details, which can lower the quality of reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

The handling of lower-quality material is fairly mediocre on the Hisense U7S. The Pentonic 700 chipset used here does not cope particularly well with strong compression artefacts. The menu includes a "Smooth and Gradient Image" function, but its performance leaves much to be desired. At the low setting tonal transitions show little improvement, although at least the image does not suffer. The medium and high settings still do not remove obvious banding between shades, and they begin to blur details; in our test material even parts of characters' faces disappeared. Interestingly, film grain remains untouched at every level. If you do use this feature, stick to the low setting. Its current behaviour needs refinement, but that is mainly down to the chipset used here.

Upscaling to 4K performs much better. Lower-resolution content gains in legibility, edges are well reproduced, and fine elements look sharp. That does not mean it recovers details that were never in the recording, but the TV makes good use of what it receives from the source. Another plus is that it does not crop the image edges, even with an SD signal.

The 60 Hz panel in the Philips PUS8209 is mainly suitable for watching films, but there is still a sense of something missing. The television does not offer any motion smoother that would allow users to adjust the fluidity of the picture to their individual preferences, which can be disappointing for some users.

Motion handling on the Hisense U7S is decent thanks to the 144 Hz refresh rate. For films there is also a motion smoother with adjustable judder and blur reduction. You can therefore keep a more cinematic motion or increase smoothness if jerky camera pans bother you. The high refresh rate is also useful for sports and gaming, but unfortunately it does not solve the panel's biggest problem.

That problem is pixel response time. Fast-moving objects leave long, clearly visible trails, as our UFO test shows. It looks worst on dark backgrounds, where the trail behind the object is particularly pronounced. So motion can be smooth, but the moving object itself loses sharpness, and that difference on the U7S is fairly easy to notice.

The Philips PUS8209 offers basic features useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and a Game Bar that makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the television will not meet the expectations of more demanding gamers who are counting on higher smoothness and image precision. Additionally, this model does not support any HDR mode dedicated to gaming, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.

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.
