Samsung U8000F (VA) vs Philips OLED770

While the U8000F with its VA panel can still be praised for decent blacks, there are no such accolades when it comes to brightness—particularly in HDR scenes. The television only achieves a maximum of just under 250 nits, which is simply too low to talk about any impressive light effects. Bright elements appear washed out, and scenes that should shine look rather flat. An interesting situation occurred during our testing of a scene from the movie Sicario 2— the screen noticeably darkened, as if the television was trying to hide its limitations in displaying blacks. One might get the impression that the device artificially darkens the image to improve contrast, but in practice, the effect doesn't make much difference, apart from the fact that we see less on the screen. Additionally, there’s the issue of colours—the U8000F doesn’t support a wide colour gamut, so one shouldn’t expect vibrant, saturated hues known from better models. The HDR image here resembles a slightly brightened SDR and... maybe that’s not such a bad thing. For this model, it’s not worth expecting a cinematic experience—better to treat HDR as a modest addition.

The Philips OLED770 doesn't try to compete with the brightest OLEDs on the market, and it's actually hard to expect that, as it's the entry-level model in Philips' range for 2025. In our measurements, it reached a maximum of around 700 nits, which allows for enjoyment of HDR effects in scenes where light appears in spots – for instance, in the flash of headlights or a starry sky. In such moments, the picture can truly amaze. However, it's different when there are more bright elements on the screen. The TV, like many cheaper OLEDs, restricts luminance at that point, and the entire image noticeably dims. This was best seen in a scene from the movie The Meg, where the sun rises behind an oil platform – the brightness dropped to around 250 nits, which is almost three times less. The HDR effect remains pleasing to the eye, but it's worth being aware that this model performs best in scenes with less intense light. Fortunately, the OLED770 also has an ace up its sleeve – the coverage of the DCI-P3 colour palette is as high as 99%, so colours in movies and games are vibrant and very close to what the creator intended.

Samsung U8000F has been tested by us in the best picture mode it offers out of the box – that is, Filmmaker Mode. This profile is supposed to theoretically provide a neutral, cinematic image, free of unnecessary enhancements and artificial beautifications. In the case of SDR content – mainly in HD or SD resolution – the television already presented itself surprisingly reasonably right out of the box. The only noticeable imperfection was brightness management. The gamma chart showed some deviations – slight brightening or dimming of certain tones – but in practice, this did not significantly affect the viewing experience. For a television in this segment, it performs quite well.

However, the situation in HDR mode looks significantly weaker. Although white balance was still acceptable, colour errors were very evident. In the Color Checker test, almost every sample was outside the target point, and the image itself appeared unnatural – colours were skewed, sometimes too cool, and at other times simply dull and lifeless. The main issue lies in hardware limitations – the U8000F does not support the wide colour gamut of DCI-P3, so it is physically unable to reproduce the colours that the HDR standard intends. Unfortunately, this is evident in almost every more demanding scene.

The first measurements already show that the factory settings of the Philips OLED770 have a lot to improve, even in Filmmaker mode. The white balance chart clearly indicates a lack of blue, giving the image a slightly yellowish tint. In practice, white is not snow-like, but leans towards warmer hues – which some may even find appealing, but from a precision standpoint, this is a deviation from the norm. The gamma, on the other hand, tends to be on the darker side – the average value is around 2.6 instead of the reference 2.4. In mid-tones, the image appears muted and more saturated, which can look too "cinematic" but detracts a bit from the naturalness. However, the most significant issues are visible in colour reproduction. The average error is relatively high, and some colours – particularly shades of grey – deviate significantly from what should be seen. In everyday viewing, this means that sometimes colours may look less natural than we would wish.

Right out of the box, the U8000F offered a pretty decent picture in SDR for its price range. We managed to tweak it a bit further – we reduced a slight purple tint and improved the gamma characteristics, giving it a more natural curve. Despite these adjustments, the TV still has a tendency to overly brighten the brightest details – the gamma chart shows a clear break that cannot be fully corrected.

On the other hand, in HDR mode, it’s noticeably weaker. It's hard to talk about any significant improvement – despite attempts to fine-tune the settings, the picture still presents considerable colour errors. A Delta E exceeding 7 indicates noticeable deviations that we couldn’t effectively reduce. Unfortunately, this is a limitation of the construction itself – the U8000F simply wasn't designed for serious HDR. In daily SDR viewing, it performs quite well, but for HDR content... it’s best not to have overly high expectations.

Philips OLED770 had shown signs from the start that it harboured significant potential, but it was hard to fully appreciate this in its factory settings. The image was often too warm, and some colours appeared as if they had lost their naturalness along the way. Calibration revealed that this television was very amenable to work – it responded to every adjustment and almost immediately unveiled another layer of its capabilities. The white balance was set in both SDR and HDR so that the yellowish haze disappeared and a neutral, clear white emerged. Gamma stabilised closer to perfection, which helped restore the naturalness of mid-tones, while shadows ceased to be artificially darkened, perhaps even with a slight brightening effect. The result was obvious... Movies are watched with greater ease; the image has cinematic depth without the feeling that something is overly darkened. However, the most interesting aspect was working on the colours. Factory errors were not dramatic, but slightly noticeable – skin tones could be too warm, and grey wasn’t always the shade we expected. After calibration, the error values dropped to around 2, and in many cases even below 1. This is a level that is definitely lower than the threshold of discernibility for the human eye. In other words, after correction, the colours finally “clicked” into place. Looking at the screen, we felt like the television had begun to speak with a full voice. Like an instrument that had finally been properly tuned.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup. This year’s model is equipped with a feature that improves the smoothness of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but still – it can be confidently said that it works effectively. However, not everything has gone perfectly. The U8000F has noticeable issues with slight image stuttering when watching very old content in very low resolution. If someone plans to play their old VHS tape, they must be prepared for the image to look slightly “choppy”.

The problem of the previously mentioned colour connections can largely be mitigated thanks to the "distortion reduction" function, which is an algorithm for smoothing tonal transitions in Philips. It works best at a low level – effectively eliminating unwanted colour bands while not introducing strange artifacts or losing image detail. This is one of those features that is truly worth keeping on.

The issue of upscaling is somewhat less impressive. Images from lower resolution can be too soft, while in some parts the characteristic "jaggies" appear. The impression is that the algorithm is trying to reconcile two contradictory directions – smoothing and sharpening – and ultimately fails to find the golden mean. As a consolation, it's worth noting that the television does not have problems with overscan, meaning it does not cut off the edges of the image, which can sometimes happen in other competing models.

The Samsung U8000F comes with a 60 Hz panel, so right from the start, it's clear that you can't expect miracles. It's simply the standard in this class – sufficient for everyday viewing, but without any fireworks. The TV offers one motion smoothing slider – a function called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in films. Higher settings provide a more "theatrical" and smoothed effect, while lower settings maintain the original character of the film with a slight 24p effect. Interestingly, there is the "LED Clear Motion" feature, or BFI mode – which inserts black frames between the frames of the image to improve motion sharpness. However, in practice, the screen flickers significantly when this is activated, and it's best to treat this as more of an experiment rather than something that genuinely improves the gaming experience.

The issue of the panel in the Philips OLED770 is not entirely straightforward. The manufacturer claims a 120 Hz panel, but our measurements showed that the screen can accept a 4K signal even at 144 Hz. This sounds like great news – because who wouldn't want an additional mode for PC gamers at this price? However, the reality turned out to be more complex. With 120 Hz content, the television behaves like most OLEDs – the image is absolutely clear, with no trace of blurring or smearing, ideal for both dynamic games and sports broadcasts. The problem only arises at 144 Hz. Unlike models with official support for this frequency, here we see the phenomenon of so-called frame skipping. This means that the television is unable to display all the frames – some of them are skipped, causing motion to lose smoothness and double outlines to appear on the screen. The effect resembles the operation of the BFI function, which Philips does not offer in this model anyway.

Samsung U8000F offers a basic set of features for gamers, which can still prove sufficient for less demanding users. Here we have an automatic gaming mode – when a game is launched on the console, the TV switches to low-latency mode by itself, significantly improving response time. We also find the VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the 'tearing' effect on the screen – as long as we stay within this range.

Unfortunately, that's about it when it comes to advantages. Add-ons like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust the HDR image to the intentions of game developers. Unfortunately – despite this feature appearing in advertising brochures and store materials – its setup on the Xbox console turned out, in practice, to be... impossible.

If someone is looking for a TV for gaming, the Philips OLED770 is a candidate that's hard to overlook. The mere fact that this is an OLED gives it a great starting point – perfect blacks and infinite contrast make evening sessions in atmospheric games look like they've been taken straight out of a cinema. Added to that is the Ambilight system, which uses LEDs on the back of the TV to extend the image onto the wall behind the screen. The effect is such that even just playing FIFA can look like a small spectacle, and in horror games, the atmosphere becomes really thick. On the technical side, it's also quite decent. The Philips OLED770 supports variable refresh rate (VRR) up to 120 Hz, has an automatic mode for gamers (ALLM), and for those using an Xbox Series X, Dolby Vision support in games is also available. You just need to know that in this mode, the input lag is slightly higher than standard, although still at an acceptable level. As a bonus, we also get the 'Game Bar', which is a special tool strip for gamers. It's not the most conveniently designed solution, but it allows for a quick view of key parameters without exiting the game. Overall, this gives a picture of a TV that has all the most important gaming features on one hand, and on the other can add something unique – Ambilight. And it's this mix of technology and visual effect that makes the OLED770 one of the better screens for gaming in a home environment.
