Philips PUS8209 vs Hisense U7S / U77SE

Unfortunately, this is where the problems start. A maximum brightness of 280 nits is definitely too low to experience the true effect of HDR. In practice, the image resembles standard SDR more, so it's hard to talk about deeper visual experiences. On the plus side, the colour gamut coverage is 91.4% DCI-P3, which will be sufficient for most films. It's also worth noting that the image is stable and there are no issues with sudden brightness or colour changes. Overall, HDR on this television is more of a formality than an actual added value. If we're looking for genuine HDR emotions, this model may not meet expectations.

The Hisense U7S has considerable HDR potential, but it can’t make full use of it in every scene. On a test pattern it reaches about 1100 nits, so the backlight is genuinely strong. In our brighter film scenes we measured around 640 to 745 nits. That’s still enough for the sun or bright highlights to have a distinct bloom and to show an advantage over SDR material. When the TV needs to light a larger portion of the image, it handles it quite well.

The problem appears with small lights on a dark background. Each of the 192 zones covers an area considerably larger than a tiny point on the screen. If the TV were to drive such a zone strongly, it would brighten the surrounding area along with the light. Hisense tries to avoid that and dims the whole zone. Blacks look better as a result, 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 highlights are noticeably muted. The U7S therefore prioritises keeping deep blacks, even at the expense of bright details. With this number of zones it’s an understandable compromise, but it’s worth remembering that the peak 1100 nits tells us about the backlight’s capability, not how brightly the TV will show every element of a film.

Colours

Hisense markets the U7S as ULED, but that’s a marketing name; the wider colour gamut here is achieved by a PFS phosphor backlight. In our measurements the TV covered about 91% of the DCI-P3 space and 71% of BT.2020. Those are good results, though a little short of the best screens on the market. The biggest shortfall is in green — the TV doesn’t even reach the DCI-P3 boundary there, so the most intense green hues will be less saturated than they should be. Most colours in HDR films and series still look suitably vivid, however. 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 distinct problems. For HD content, the white balance is characterised by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in mid-tones, has serious issues at the beginning and end of the graph. Drops in shadows result in a loss of detail in dark areas, and spikes in bright areas make some elements look unnatural.

For high-quality content in 4K HDR, the situation reverses. In this case, blue dominates, leading to an artificial image boost effect, reminiscent of unnatural retail settings. Such an image looks unappealing and does not align with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference graph, causing the image to appear too dark, stripping depth and detail from HDR content.

Against this backdrop, the errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively affects the overall image quality. The Filmmaker mode, while the best among those available, requires substantial corrections to truly convey the full vision of the director.

Factory colours on the Hisense U7S are decent, but there are a few things to fix. In SDR the white balance favours red, so the image looks too warm, in places with a slightly pink tint. You can see this on faces and bright, neutral surfaces. Gamma also runs below the target, so the TV brightens the image, especially in darker areas. That makes it easier to see shadow detail, but the scene loses some of its depth.

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

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

Calibrating the Hisense U7S did the most for SDR content. We managed to even out the white balance, so the earlier warm tint is gone and whites and greys look neutral. Gamma now sits very close to the reference, so the TV no longer brightens the image unnecessarily and darker scenes have regained depth. Color Checker measurements confirm the improvement: most errors are below 2. For watching regular TV and SDR films, this delivers a really well calibrated picture. Calibration in HDR wasn’t as smooth. The TV lacks an effective way to correct the EOTF curve, so Hisense still interprets the film’s brightness a bit on its own. It brightens parts of the image and, depending on the scene and local dimming, can tone down the brightest elements. That couldn’t be eliminated by calibration. This also shows up in the Color Checker results, where many errors remain around 3–4 and some exceed 7. In SDR the result is therefore very good, but in HDR we have to 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, particularly when set to the minimum level. Unfortunately, this comes at a cost – the feature also smooths out details like material textures. On the plus side, it’s worth noting that the operation of this option does not negatively affect the 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, issues with aliasing of certain elements, such as branches or small details, can sometimes be noticed, which may decrease the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

The processing of lower-quality material in the Hisense U7S is fairly average. The Pentonic 700 chipset used here doesn't cope particularly well with the effects of heavy compression. There's a "Smooth and Gradient Picture" function in the menu, but its performance leaves a lot to be desired. At the low setting it's hard to see any improvement in tonal transitions, though at least the picture doesn't suffer. Medium and high settings still don't remove visible banding between tones and begin to blur details; in our clips parts of characters' faces even vanished. Interestingly, film grain remains untouched at every level. If you do use this function, stick to the low setting. Its current performance needs refinement, but that's mainly down to the processor used here.

Upscaling to 4K performs much better. Lower-resolution content gains clarity, edges are well reproduced and fine details look sharp. That doesn't mean the TV can recover details that weren't in the recording, but it makes good use of what's provided by the source. Another plus is the lack of edge cropping, even with an SD signal.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but here you can also feel a certain shortcoming. The television does not offer any motion smoothing that would allow you to adjust the fluidity of the picture to individual preferences, which for some users may be disappointing.

Motion handling on the Hisense U7S is decent thanks to its 144 Hz refresh rate. For films there's also a motion smoothing option with adjustable judder and blur reduction. You can keep a more cinematic feel to motion or increase smoothness if choppy camera pans bother you. High refresh is also useful for sport and gaming, but unfortunately it doesn't solve the panel's biggest problem.

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

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

Unfortunately, due to the 60 Hz panel, the TV will not meet the expectations of more demanding gamers who are looking for higher fluidity and precision of image. 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 plenty to offer gamers. You get two HDMI 2.1 ports and support for 120 Hz in Full HD, 1440p and 4K, so modern consoles’ capabilities are well utilised. 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 lot of choice, although it’s worth remembering the motion smearing mentioned earlier, which the high refresh rate doesn’t eliminate. VRR and ALLM are present as well. VRR helps keep the picture tear-free when a game’s frame rate changes. ALLM automatically switches the TV into game mode, so you don’t have to go into 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 at 120 Hz. Importantly, that format does not cause significant input lag here. The Game Bar also looks great. It’s clear and attractive, and lets you quickly check what signal the TV is receiving. Handy gaming settings are close to hand too, including shadow brightening. If it’s hard to spot an opponent in a dark game, you can improve visibility without digging through the whole menu.

Our biggest complaint is HGiG. Hisense keeps doing its own tone mapping, which makes setting up HDR on the console confusing. You adjust the checkerboard pattern, and the TV continually alters its appearance. As a result, the point at which the pattern disappears does not correctly indicate the display’s brightness limit, and it’s easy to set the value too high. For this model it’s better to set the target HDR brightness on the console to around 900 to 1000 nits, rather than rely on the configurator.
