Philips OLED809/819 vs Hisense E7Q / E79Q

The Philips OLED 809 delivers a highly satisfactory HDR effect. The television can reach luminance levels exceeding 900 nits in most scenes, and in some cases, even surpassing 1000 nits. This brightness ensures a rich and immersive experience for HDR content with a wide tonal range. The only exception occurs in a scene from the movie The Meg, where a large amount of bright white occupies most of the screen, preventing the TV from reaching higher brightness levels. However, this is not a significant issue, as the performance is still a considerable improvement over its predecessor.

Overall, these brightness levels, especially for an OLED panel not equipped with MLA technology, impress. Coupled with excellent coverage of the DCI-P3 colour spectrum, the Philips OLED 809 offers a truly spectacular HDR viewing experience.

Hisense E7Q / E79Q is a television with average brightness, whose peak luminance level is around 350-380 nits. This is an absolute minimum that allows for watching HDR content in a way that is close to the creators' intentions, although without a clear "wow" effect. The results of synthetic tests on white images have been confirmed in practice – in movie scenes, the bright parts of the image are stable and fairly uniform, but it is hard to speak of a true "lighting impact" here. In everyday use, for example, while watching Netflix or YouTube, the HDR effect is acceptable and is completely sufficient for most users. However, it must be stated clearly – this is not the level of top screens, and one should not expect that at this price point. Fortunately, the Hisense E7Q / E79Q has an advantage that allows it to gain quite a few points: it is a PFS LED QLED panel, utilizing an additional phosphor layer that improves color reproduction. The measured range of the DCI-P3 palette is around 92%, which means that the colors in most scenes are vibrant, well-saturated, and pleasing to the eye, especially for this price range.

The best factory mode in which we performed all our tests was "Filmmaker," which is quite standard in televisions from this manufacturer. However, let’s first examine its characteristics before the calibration process. The first aspect we will focus on is white balance, as it is critical to ensuring the image remains free from any colour cast. The chart clearly shows that in both SDR and HDR materials, two colours dominated significantly: red and green, resulting in a strong yellow tint that affected the entire image. This was particularly noticeable on the "ColourChecker" palette, where all colours shifted towards their warmer counterparts.

The second aspect we will assess is what we consider to be the two most important charts for evaluating picture quality: gamma and the Electro-Optical Transfer Function (EOTF) curve. Both aim to maintain appropriate brightness and contrast. The first chart, which describes the brightness levels in SDR materials, shows that the brightness was significantly lower than the reference value marked by the orange line. This resulted in a sharp increase in brightness and a notable decrease in contrast, which was inconsistent with typical OLED television behaviour. The EOTF curve, on the other hand, showed greater "moderation," subtly brightening the overall image only up to 50% of the maximum brightness.

In Filmmaker mode, the Hisense E7Q / E79Q television was able to really surprise positively. Even after the first measurements, it turned out that the white balance is quite well calibrated, and the only minor deviation was a slight tendency toward a purple hue, which we mentioned earlier. However, this did not significantly affect the overall character of the image – it remained coherent and pleasant to perceive. A much larger problem turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening the contrast and taking away its depth. Gamma values could drop from the reference 2.4 down to about 1.9, making the image appear as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.

Philips, like most leading manufacturers, has been providing advanced calibration tools for years. The inclusion of 2- and 20-point grayscale adjustments, along with an advanced CMS (Color Management System), has yielded extremely beneficial results and fundamentally improved the perceived image. Nearly every element previously mentioned has undergone a transformation and has been restored to its natural state. This is particularly noticeable in the "ColourChecker" palette, where the measured colour samples align harmoniously. Notably, the white balance has been excellently calibrated, ensuring a pure image free from unwanted tint in both SDR and HDR content. The previously problematic gamma has been well addressed, with only minor errors that do not impact the overall performance. Similarly, the EOTF curve has been refined, removing the subtle brightening effect, and now offers a truly reference-quality presentation.

The biggest beneficiary of calibration for the Hisense E7Q / E79Q turned out to be the SDR mode without a doubt. It managed to achieve nearly perfect picture quality – most errors in the Color Checker test dropped below a value of 3, and often even below 2, which is a remarkable result for this class of equipment. The greatest improvement came from aligning the brightness characteristic (gamma), making the picture no longer look washed out and regaining its natural depth. In HDR content, colors were also improved, and the purple tint we mentioned earlier was eliminated, but errors in the Color Checker measurements were still noticeable. This is due to the fact that – as is often the case with Hisense televisions – the screen manipulates brightness quite strongly, oversaturating some colors. This was also indicated by the EOTF curve, which was slightly above the reference values, suggesting these minor problems with excessive brightening. Despite this flaw and the construction limitations that arise with HDR content, the Hisense E7Q / E79Q gained a lot after calibration. In everyday use, the television presents a cohesive, natural, and pleasant-to-the-eye picture, and the difference compared to factory settings is truly vast.

Philips OLED 809 struggled significantly in the smooth tonal transitions test. Focusing on the TV's algorithms, particularly the feature responsible for removing posterisation, the results were disappointing. This function, which offers several adjustable settings, proved ineffective in practice. The highest setting, while it does mitigate inconsistencies, it simultaneously blurs the entire image, rendering it virtually useless.

When dealing with lower-quality content, the performance of image upscaling algorithms becomes crucial. In this regard, the algorithms implemented in the OLED 809 perform admirably. They enhance image quality effectively, with minimal visible artefacts. Although slight edge fraying can occasionally be observed, it is unlikely to be noticeable during typical viewing sessions.

In the case of Hisense E7Q / E79Q, upscaling and digital image processing are not the strongest features of this television. It is clear that the manufacturer opted for simplicity rather than advanced image processing algorithms. The television does not offer any functions for smoothing tonal transitions or systems for improving image clarity, which means that lower resolution materials simply look very raw. On the screen, subtle compression edges can be noticed, which better processors in other models can effectively hide.

During tests of HD materials, we noticed that the E7Q tries to artificially enhance detail, which sometimes works and sometimes has the opposite effect – the image becomes soft, slightly smeared, at times even "watery." There is no aggressive sharpening that ruins naturalness, but there is also no finesse in detailing that better image processors offer.

The maximum refresh rate achievable on the Philips OLED 809 is 144 Hz, a feature that can be fully utilised when connected to a high-performance PC. However, when connected to consoles or used for standard television viewing, the refresh rate remains at typical values. For users seeking enhanced motion fluidity or wishing to eliminate the characteristic choppiness of films shot at 24 fps, Philips provides a sophisticated motion-smoothing system.

In the settings menu, there is a "Smoothness" slider designed to reduce choppiness, along with a "Motion Blur Reduction" option to enhance the sharpness of fast-moving elements. These features perform impressively and allow for granular adjustments, ensuring that each setting has a tangible impact on motion perception. Notably, the system operates effectively at a refresh rate of 120 Hz, taking advantage of multiples of video frame rates. With this comprehensive range of options, users can easily fine-tune the settings to suit their preferences. For example, slight smoothing without inducing the soap opera effect offers a balanced viewing experience.

Motion clarity on the OLED 809 is further bolstered by the exceptional response time of the OLED panel, measured at approximately 0.1 ms. This surpasses the performance of IPS/ADS or VA panels, making OLED technology unrivalled in this area.

Hisense E7Q / E79Q is a television with a 60 Hz screen, so 4K sports fans may feel a slight disappointment – we simply won't see such smooth images here as in more expensive models with higher refresh rates. Fortunately, when it comes to movies, the situation is much better. Cinematic materials recorded at 24 frames per second can be displayed here using a motion smoothing feature, allowing the user to adjust the image to their preferences – more cinematic with a visible frame or smoother, in a theatrical style.

The Philips OLED 809 fully supports all technologies included in the HDMI 2.1 standard, and during testing, each activated without issue. This makes the TV an excellent choice for gamers, whether on console or PC. Notably, it features HGIG mode as a strong alternative to Dolby Vision, which is less ideal for gaming on this model due to its high input lag.

The TV also includes a dedicated GameBar for monitoring gameplay parameters and adjusting settings quickly. Features like a crosshair overlay for sniper shots, shadow enhancement for better visibility, and a colour filter for gamers with visual impairments further enhance its gaming appeal.

In summary, the OLED 809 is a fantastic choice for gaming, equipped with VRR, ALLM, G-Sync, FreeSync, and HDR Dolby Vision gaming for a deeply immersive experience. The only drawback is the artificial sharpness in game mode, which cannot be fully softened, regardless of settings.

Hisense E7Q / E79Q is truly a successful television for gamers, even though it doesn't support 4K signal at 120 Hz. However, the manufacturer has included a set of features that until recently could only be found in more expensive models. There is ALLM, or automatic switching to low-latency mode, which allows the television to activate game mode with very low input lag. We also have VRR, functioning up to 60 Hz – this may not seem impressive on paper, but in practice, it is fully sufficient, as most games on consoles do not exceed this limit. All these settings can be quickly found in the Game Bar panel, a convenient menu created specifically for gamers. From this level, you can change picture modes, turn on a frame rate counter, or even… a crosshair on the screen – in the Vidaa system humorously named "target point," which is a result of awkward translation by the Chinese manufacturer.

Particularly praiseworthy is the ability to play in 1080p at 120 Hz, which realistically improves the smoothness and responsiveness of the image. This way, if someone wants to play a few titles at a higher refresh rate, they can simply lower the resolution and enjoy significantly smoother motion. Despite the lack of 4K@120Hz, Hisense E7Q / E79Q really performs well as a television for gamers – especially those who are not looking for perfection, but a solid and fast screen for everyday gaming.
