Dreame Q100 vs Samsung S85H

Unfortunately the Dreame Q100 is too simple, and above all too dim, a television to talk about a true HDR effect. The peak brightness we measured reaches at most about 300 nits, which is clearly too little for bright elements of the image to actually 'pop' with light. In fact, this is a level we more often associate with SDR material than with HDR. It therefore lacks the brightness headroom offered by more expensive televisions that makes highlights, reflections and the sun look noticeably more striking.

HDR colours

Fortunately the Q100 makes up for this a little elsewhere. The manufacturer markets it as a QLED television, although in practice a PFS filter is responsible for widening the colour palette. The DCI-P3 colour space we measured is covered at roughly 92%, and BT.2020 at about 67%. These are not top-tier figures, but still clearly better than simple LCD televisions without an additional gamut-expanding layer. As a result, HDR material can at least offer more saturated and varied colours, even if the brightness itself does not yet allow us to speak of a fully fledged HDR effect.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 series. In the same movie scenes last year's model stayed closer to around 700 nits, while the S85H can reach roughly 800 nits. This isn't a change that completely transforms HDR perception, but that extra brightness is noticeable, especially with pinpoint highlights, specular reflections and stronger special effects. Around 800 nits is already a very good result for an entry-level OLED and in most films it's enough for HDR to have the proper impact. Bright elements can stand out clearly against perfect black, and it's still that contrast that does most of the work. You do need to bear in mind a typical limitation of organic panel technology. When a very bright scene covers a large part of the screen, brightness can drop by almost half. That's the effect of the panel's protection mechanisms, which limit its power with large bright areas.

Colours

The S85H can deliver very pleasing, saturated colours and in most HDR films it looks really good in that respect. We measured around 95% DCI-P3 coverage, so the palette most commonly used in movies is reproduced to a very high degree. Skin tones, greens and stronger reds still have the right intensity, and in normal viewing it's hard to fault them. Only when you look wider at BT.2020 do the limitations of the new OLED SE panel become apparent. Coverage was about 70%, a little less than previous-generation WOLEDs and noticeably less than QD-OLED panels. In films this is not a big loss, because most productions rarely use such highly saturated colours. You're more likely to notice it in games, where creators often opt for more intense colours.

We chose the "Film" mode for testing and, in our opinion, it is by far the best of the available presets. There are none of the heavily boosted, unnatural colours you can see, for example, in the Vivid/Dynamic mode. The picture looks quite reasonable straight away, although it falls a little short of perfect. In SDR material the most noticeable issue was a slight warming of the image. The white balance had too much red, which made whites lean towards a warmer hue, and a similar tint was visible in shades of grey. In HDR the situation was a little different. Here blue had a slight advantage, making the picture a touch cooler. These are not major faults, though. For such an inexpensive TV, the factory settings on our unit were fairly decent, and the "Film" mode already delivers a relatively natural image without much fiddling with the settings.

For colour evaluation we naturally chose Filmmaker mode, and in SDR our S85H sample was very well set up from the factory. The largest deviation is in the white balance, where, as brightness rises, there is a slight lack of blue. In practice this means whites and greys have a subtly warmer tint than they should. However, this is not a major fault and during normal viewing it is unlikely to be very noticeable. Gamma also stays close to the reference value, so the image is neither overly bright nor unnecessarily dim. The S85H’s SDR picture quality is therefore very good straight out of the box. A few more imperfections appear in HDR. Here the white balance drifts more with increasing brightness, blue starts to dominate and the red component is clearly lacking. This also translates into larger errors for some colours. They do not yet amount to shifts that completely change the character of the image, but in direct comparison with a reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

Contrary to appearances, the Dreame Q100 is quite well prepared for image calibration. The menu contains quite a few advanced picture settings that allow its characteristics to be adjusted fairly precisely. In our case the most work was required on the white balance, both in SDR and HDR. After correction SDR content looked very good. We managed to achieve a practically neutral white balance and natural colours, with the main remaining limitation being the black level itself, stemming from the panel construction and the lack of local dimming.

In HDR we also managed to improve white balance and colour reproduction, but here the limitations of the TV's electronics become apparent more quickly. Even after very precise adjustment of the EOTF curve, the Q100 does not always follow it correctly during actual scenes. In some content it can also brighten the image further, causing some parts to look brighter than they should, and in bright areas some details can be lost as a result.

Calibration yields very good results on the S85H. First and foremost, it was possible to set the white balance almost perfectly, which removes the slightly too warm character of the image that was previously visible in SDR. Colour reproduction itself also improves markedly, with most errors falling to a very low level and in everyday viewing it is hard to speak of any noticeable inaccuracies. You can also make significant improvements in HDR, although some issues remain due to the TV's inherent characteristics. The S85H does not always hold the brightness curve perfectly; the darkest parts are slightly lifted, and as you approach the panel's limits small deviations are visible in the brightest areas. Added to this is the limited coverage of the wider BT.2020 gamut, which of course cannot be overcome by any calibration. Despite this, the end result is very good and, after calibration, the S85H can produce a really well-tuned, natural image.

The weakest point of the Dreame Q100 is its digital image processing capabilities. The processor used copes only moderately well with enhancing weaker sources, and the menu lacks any function that effectively smooths unsightly tonal transitions or reduces visible posterisation. Upscaling itself is also unimpressive. With low-resolution material the image is fairly soft and lacks faithful detail reproduction. Additionally, the Q100 tends to overscan, slightly cropping the edges of the image with very poor sources, such as 480p material. In everyday viewing of HD or 4K content this won't be a major problem, but with older recordings the processor's limitations become clearly visible.

Samsung has fitted the S85H with the same proprietary AI NQ4 Gen2 processor used in last year’s S85F and, in terms of digital image processing, it performs quite well. Upscaling is one of the model’s stronger points. Lower-resolution material is well sharpened, edges look natural, and the picture does not feel overly artificial. One caveat is a typical Samsung trait: at very low resolutions you cannot completely disable overscan, so the TV may slightly crop the left edge of the image. The "noise reduction" function also works very well, smoothing weaker tonal transitions. The processor can effectively remove posterisation and other imperfections visible in lower-quality material. However, you need to be careful with the strength of this function, because Samsung can be quite aggressive here. When it is activated, small image details, such as the texture of skin or clothing, can start to disappear along with the unwanted artefacts.

The VA panel used in the Dreame Q100 has a native 60 Hz refresh rate, so from the outset this is not a TV designed for the most demanding sports fans or gamers. The manufacturer does mention the ability to run at 120 Hz, and that option is indeed available, but it mainly applies to a mode intended for gamers. In everyday use the Q100 should therefore be treated as a conventional 60 Hz TV. For fast-paced sports broadcasts or rapid gameplay this means less smooth motion than in models with 120 Hz panels or higher. On the plus side, the panel’s response time is worth noting. The VA panel does not exhibit excessive smearing, so motion remains quite clear and does not leave strong, blurred trails behind moving objects. For films you can also use a simple motion-smoothing system. The manufacturer has prepared several ready-made presets that help reduce the characteristic judder in material shot at 24 frames per second.

The S85H uses an OLED panel, so it performs excellently for motion blur. Pixels respond virtually instantly, so moving objects do not leave the characteristic trailing seen on some LCD TVs. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during rapid motion. The panel itself runs at 120 Hz. That is more than sufficient for films, TV series, sport and console gaming. It is a pity Samsung did not include a higher refresh rate aimed at PC gamers, as more and more TVs now offer 144 or even 165 Hz at 4K. However, that does not affect motion handling in films or sport.

You also have a classic motion-smoothing feature with two settings, blur reduction and judder reduction. So you can decide whether films should retain their cinematic 24 frames per second or whether you prefer to smooth them a little. The S85H gives plenty of freedom here, and the interpolation works well and, with sensible settings, does not generate too many artefacts.

The Dreame Q100 is not a strictly gaming device, but for console use it offers a reasonable package. It provides VRR to eliminate screen tearing and ALLM, which automatically switches the TV to a low-latency mode when it detects a console signal. An interesting compromise is support for a 120 Hz mode. The panel won’t achieve that refresh rate in 4K, but dropping to 1080p lets you play at 120 frames per second. If a given title prioritises smoothness over high resolution (and the game offers such a mode), it’s worth using this option. There’s also a handy Game Bar on board, allowing you to quickly change display settings, switch the refresh mode or add a virtual crosshair. Admittedly the HGiG implementation is weak here, but it earns points for supporting Dolby Vision Gaming on Xbox Series X and S. This is not a panel for technological purists, but for casual console gaming it performs flawlessly, especially when you opt to trade 4K for a smoother Full HD.

The Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a PC. The manufacturer hasn't skimped on ports and all four HDMI ports support full HDMI 2.1. That means you can use 4K at 120 Hz, VRR and ALLM without worrying which input your console is plugged into. With multiple devices that matters a lot, because you don't have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very comprehensive. The S85H supports VRR, FreeSync and automatic game mode switching, and Samsung also offers its extensive Game Bar where you can quickly check key signal parameters and change settings without leaving the game. The only notable omission is Dolby Vision, which will matter mainly to Xbox owners. This, incidentally, is typical of Samsung TVs. Game Motion Plus performs very well, and it's one of the features that have set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as much increase in input lag as a conventional motion interpolator. In practice, with slower-paced games, racing titles or action games this can really improve the perceived motion, especially if you're sensitive to low frame rates.
