Philips PUS7009 (IPS) vs Hisense U7S / U77SE

In terms of HDR effect quality, PUS7009 (IPS) performs very poorly. A brightness level of 250 nits does not allow for enjoyment of HDR effects, and the image resembles a more standard SDR. There is no talk of dynamic effects or vivid bursts of light. The coverage of the DCI-P3 colour gamut is only 75%, which is decidedly insufficient. The lack of full colour coverage means that the colours are not as vibrant as they should be, resulting in a flat and unconvincing image. There are no aspects for which this model could be praised in the context of HDR.

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.

The television was tested in film mode, which – despite its name – does not provide accurate image display. The white balance in both 4K HDR and HD/SDR content is characterised by drops in red, causing the image to appear cooler and the colours to lose their natural warmth. The gamma brightness characteristics and the EOTF curve confirm that the television has issues maintaining appropriate brightness – it heavily boosts it, resulting in an unnaturally washed-out image. This effect can be seen in the comparisons below, where the entire image appears as if it has a milky filter applied. Additionally, the limited coverage of a wide colour gamut also does not favour quality – colour checker tests indicate significant colour variations, making it difficult to achieve faithful image reproduction.

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 picture has significantly improved, especially in terms of white balance, which is now more stable, and the shades have taken on a natural quality, eliminating the previous impression of a picture that was too cool. Calibration has brought noticeable benefits in terms of tonality – shadows and midtones are now more realistic, and the overall effect seems more harmonious. Unfortunately, hardware limitations still affect the quality of the image. The brightness characteristics remain problematic, despite our efforts, and due to the poor coverage of the DCI-P3 and BT.2020 colour gamut, delta E errors are still at a high level. Although calibration has improved some aspects, the television still does not allow for complete satisfaction.

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.

When it comes to tonal transitions in low-quality material, a feature named "Distortion Reduction" (set to "minimum") effectively improves gradation, eliminating ugly tonal transitions. However, this setting on Philips televisions is quite aggressive – while it does not blur the grain or good-quality material, it can introduce undesirable effects and blur elements that should remain sharp when the signal is poorer.

In terms of image scaling, Philips PUS7009 performs reasonably well. A significant advantage is the absence of cropped image edges, meaning no overscan, which allows for the display of the full frame without loss. The image is noticeably enhanced, making characters and backgrounds, such as the model or branches in the background, appear quite detailed and natural, even with lower quality signals. Although scaling is not perfect, as it can remove desirable details in the distance, the results are good enough to satisfy most users.

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.

Philips PUS7009 does not have any motion smoothing features for films, which means we cannot choose whether the picture should be more choppy or more cinematic. These features could improve more dynamic scenes. As for motion blur, despite using a 60Hz IPS panel, the situation looks quite good. The response time between pixels is better than in versions with a VA panel, which keeps motion blur at an acceptable level and does not significantly affect the comfort of watching dynamic scenes.

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.

In terms of compatibility with consoles, Philips PUS7009 is suitable for casual gamers. Despite the use of HDMI 2.0, the television offers access to features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Game Bar. ALLM automatically switches the television to low latency mode, allowing for quicker response times during gameplay, while VRR dynamically adjusts the refresh rate to reduce the tearing effect. Game Bar is a tool that provides quick access to game settings and real-time monitoring of parameters - although we believe it appears the weakest compared to competing Game Bars.

Unfortunately, more demanding gamers may be disappointed. The Philips PUS7009 does not support advanced HDR formats in games or high refresh rates, due to the use of a 60 Hz panel. The lack of support for these features limits the television's ability to deliver smooth and fully detailed experiences during dynamic gameplay.

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.
