Samsung QLED Q80D vs Hisense E8Q

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

Since the E8Q is a twin of the U7Q, it’s no surprise that the quality of the HDR effect is nearly identical. On paper, it looks promising – a peak brightness of 800 nits can impress in many scenes. Moments such as flashes of light in “The Meg” or shots of the sun in “Life of Pi” can indeed evoke a 'wow' effect. But the longer we watch, the more we notice the limitations. The problem arises when small, bright details need to be shown against a dark background. In such situations, the dimming algorithms try to preserve contrast but end up dimming what should shine the most. Instead of dazzling details, we get almost invisible points of light. This is typical for Mini-LEDs in this price segment and is not surprising – but it’s worth knowing that the HDR effect will not always be fully preserved. Fortunately, the colour performance offers reasons to be pleased. Coverage of the DCI-P3 colour gamut at around 94% is a very good result, and the applied layer of quantum dots (more precisely, PFS) does its job – the colours are saturated and vibrant, especially with 4K content.

In "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

Testing the Hisense E8Q in Filmmaker mode, we were hoping for a possibly neutral image close to the director's vision. Unfortunately – although it doesn't look bad on paper (the colour reproduction errors are not significant), in practice the image appears not entirely natural. The reason? An overly strong boost in blue colour and a lack of red in the white balance. The effect? Scenes look cool, and the white seems slightly bluish. Alongside the U7Q model, we also noticed a specific approach to brightness management here. The brightness mapping curve for HDR content (EOTF) shows that the television can significantly dim small, bright elements on the screen to maintain contrast – but sometimes it goes too far in this. On the other hand, larger, very bright areas can be excessively brightened, which disrupts tonal balance. This is a compromise that may not suit everyone – especially if you want an as faithful image as possible right out of the box.

The film mode after calibration looks significantly better than the one you can see when taken out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

The calibration of the Movie mode yielded really good results, especially when it comes to SDR content. We managed to balance the white levels, which made the image look more natural – it appeared almost reference-quality. The colours were well-saturated, and the overall perception of the content improved significantly. Unfortunately, when we switched to HDR materials, familiar issues from the U7Q model returned. The television still likes to "do its own thing," as evident from the analysis of the brightness characteristic EOTF – despite calibration, the E8Q still dimmed fine details in the shadows, while the bright areas of the screen could be excessively boosted. In practice, this means that in darker scenes, some of the smallest details could simply disappear. Although it must be acknowledged that the entire calibration process brought a lot of good, not everything can be circumvented – even with the use of professional tools. The E8Q can impress with its picture, but in HDR content, its design limitations become apparent, and it is worth keeping this in mind.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

In the case of older materials with lower quality, a gentle smoothing of tonal transitions often comes in handy. The Hisense E8Q, like the U7Q, features an "Smoothing and Gradient Image" function, but unfortunately – its effectiveness leaves much to be desired. The "Low" mode is almost imperceptible in operation, and the higher settings do not improve transitions but simply blur the details. The good news is that the function does not compromise film grain, meaning it does not worsen the structure of the image. On the plus side, scaling is commendable. The television is able to sensibly upscale older content to a higher resolution – without artificially accentuating contours or excessive sharpening. Although it does not match the best models in this category, it performs quite well for its class.

The Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

Similar to the U7Q, the E8Q model is a fast television designed for dynamic content. It supports a refresh rate of 144 Hz at 4K resolution, and if, for some reason, someone is still gaming in Full HD – it can even reach 240 Hz. This is a significant advantage, especially for PC users looking for maximum smoothness. In everyday use, the television performs very well. The "Ultra Motion Smoothness" mode offers two sliders that allow you to customise the picture to your preference – whether more cinematic with the film frame preserved or highly smoothed, almost "series-like". It's good that the manufacturer provides a choice here instead of imposing one style. On sports material, live broadcasts, or in games – movement looks clean and stable. Of course, it is not at the OLED level, but for this price range, the E8Q performs really well.

The Samsung Q80D television is a true gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

Hisense E8Q does not hide its gaming heritage. Even the specifications reveal that we are dealing with a television that will perform excellently as a gaming screen. Variable Refresh Rate (VRR)? It's there. Automatic switching to game mode (ALLM)? That's there too. Additionally, there is impressive refresh rate – 120 Hz in 4K or even 240 Hz in Full HD. Such a set is rare in this price segment. Everything works smoothly and without major surprises. The only missing element – similar to the U7Q – is support for HGiG. It’s a shame, as this feature facilitates adjusting the brightness curve to the capabilities of a specific television, improving visual compatibility with the intentions of HDR game creators. Without it, one has to manually fiddle with the settings, which does not always yield a satisfactory result.
