Samsung QLED Q80D vs Samsung R85H / R86H

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable 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., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired lack of brightness, and the HDR effect resembles that of SDR.

When it comes to brightness, the R85H performs quite well. In most of our test scenes the TV reaches around 800–900 nits, and with larger bright elements it can exceed 1000 nits. These aren't, of course, on the level of the most expensive Mini-LEDs, but they're more than enough for watching films and TV series in HDR and the effect can be quite noticeable. The problem reappears in more demanding scenes, where there's a small bright element on a very dark background. Here the TV can greatly reduce its brightness to avoid lighting up too much of the screen. In our measurements such small highlights fell as low as around 200–250 nits, so it's clear that a limited number of local dimming zones combined with the specific behaviour of the algorithm has consequences here. Fortunately, it doesn't affect viewing all the time. In typical, mixed HDR scenes the R85H looks good and can provide good image dynamics. It's just that with very small points of light you shouldn't expect as strong an effect as on TVs with a much larger number of zones or on OLEDs.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

In Filmmaker mode our R85H sample in SDR performed adequately, but a few issues immediately stood out in the measurements. In the white balance, as brightness increased more red was added while blue decreased. As a result, the brighter parts of the image had a slightly too-warm tint. Gamma only held the target value at the start. It then gradually fell, which left most of the image a little too bright. The combination of these two factors also affected the colours, with errors growing particularly in the brighter and more saturated samples. It did not look bad, but for Filmmaker mode we expected a bit more accuracy. Interestingly, our sample fared noticeably better in HDR. The white balance was much more even and the individual components stayed close to one another across most of the range. Only in the brightest parts did red start to be lacking, causing white to shift subtly. The EOTF curve looked very good, tracking the target luminance across almost the entire range. That does not mean HDR colours were perfect. The Colour Checker still shows some deviations, especially for some of the more saturated colours, but the errors are clearly smaller than in SDR.

The movie mode after calibration looks significantly better than the one you see right 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 (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. 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 on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to 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.

After calibration the R85H shows it has really substantial colour reproduction capabilities. SDR performed best: white balance could be brought almost perfectly into line, and gamma stays very close to the target value across most of the range. That also translated into very low errors in the ColorChecker, so there's really little to criticise here. HDR also shows a clear improvement, although some issues can't be corrected as well. At the highest brightness levels the character of the backlight itself becomes apparent and the individual components of the white balance begin to diverge. The same applies to the most saturated colours, which don't always land exactly where they should. Despite these limitations the overall picture is considerably more accurate than factory settings, and the biggest difference is definitely visible in SDR. However, there is one thing calibration can't fix. With heavily saturated elements the colour can slightly bleed onto adjacent bright areas of the image. It's easiest to notice on white, which can pick up a faint tint of a neighbouring hue. It doesn't occur in every scene, but when the material is demanding the effect can be visible. This is more a feature of the way the RGB backlight operates than an issue with picture settings.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

In the R85H, image processing is handled by the Micro RGB AI Processor. The name is new, but when it comes to upscaling lower-quality sources, the TV's behaviour is very similar to what Samsung has shown before. And that's not a bad thing, because Samsung has handled this aspect quite well for years. Lower-resolution material is displayed cleanly, edges don't become overly soft, and the TV doesn't try to artificially extract detail at all costs. The result is simply balanced, and for regular TV or older recordings the R85H performs as you'd expect from Samsung at this level. There's still a small downside: overscan, which can't be completely switched off at the lowest resolutions. Another matter is the extra processing applied to low-quality sources. The R85H can smooth posterization and tidy up heavily compressed footage, but it's worth emphasising that it does so relatively aggressively. At stronger noise reduction settings it starts removing not only compression artefacts but also fine detail and the natural film grain. So it's best to use it only when the source actually needs it.

The Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

R85H has a 144 Hz panel, so motion handling is really good here. You should remember that the extra hertz above 120 will mainly be used when connected to a computer, so in this category we don't treat them as any particular advantage. For films and TV, what's more important is that the panel is fast enough to provide access to an advanced motion smoothing feature, "Motion Clarity", which lets us set motion from more film-like to very smooth. The panel's response time is a bit worse. Since it's a VA panel, fast-moving objects can leave a slight trail. On a bright background this isn't very noticeable, but the darker the scene, the more noticeable the smearing becomes. This is a typical characteristic of this type of panel and it's easiest to spot in dark scenes.

The Samsung Q80D TV is a real 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 at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing a console.

Samsung has been steadily expanding its gamer features for several years, and the R85H really doesn't lack anything important. The TV supports 4K at 120 Hz, VRR and ALLM, so it can easily make full use of the PlayStation 5 or Xbox Series X. HGiG also works properly, so when HDR is set correctly on the console, games maintain their intended brightness and you don't unnecessarily lose detail in the brightest parts of the image. The only bigger omission is Dolby Vision Gaming, which Samsung doesn't support on any of its TVs.

The Game Bar is also very useful, a handy menu you can bring up without leaving the game. You can quickly check the frame rate, VRR status or change the key picture settings. Samsung also includes a few less obvious features, like the ability to change the aspect ratio or Game Motion Plus, which can further smooth games running at 30 or 60 fps. Of course this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting option for some.
