Dreame Q100 vs Samsung S85H

The Dreame Q100 is unfortunately too simple, and above all too dim, to really deliver a true HDR effect. Our measured peak brightness reaches at most around 300 nits, which is definitely too low for bright parts of the image to really "hit" you 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 TVs, which makes highlights, reflections and the sun look noticeably more impressive.

HDR colours

Fortunately the Q100 makes up for some of that elsewhere. The manufacturer markets it as a QLED TV, although in practice a PFS filter is responsible for widening the colour palette. Our measurements show coverage of about 92% of DCI-P3 and around 67% of BT.2020. These are not top-tier numbers, but still clearly better than basic LCD TVs without an extra layer to expand the gamut. That means HDR material can at least offer more saturated and varied colours, even if the brightness alone does not yet allow you to speak of a fully convincing HDR effect.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 lineup. In the same film scenes last year’s model sat closer to about 700 nits, while the S85H can reach roughly 800 nits. That’s not a change that completely transforms the HDR experience, but the extra headroom is noticeable, especially with point highlights, reflections or stronger special effects. Around 800 nits is a very good result for an entry-level OLED and in most films it’s enough for HDR to have the necessary punch. Bright elements can clearly stand out against perfect blacks, and that contrast is still doing most of the work here. However, you need to remember the typical limitation of OLED technology. When a very bright scene covers a large portion of the screen, brightness can drop to almost half. This is the result of panel protections that limit its output with large bright areas.

Colours

The S85H can deliver very pleasant, saturated colours and in most HDR films it looks really good in that regard. We measured around 95% coverage of DCI-P3, so the palette most commonly used in films is reproduced to a very high degree. Skin tones, greens and stronger reds still have appropriate intensity and under normal viewing it’s hard to have major complaints. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was about 70%, a bit less than WOLEDs of the previous generation and noticeably less than QD-OLED panels. In films this isn’t a big loss, since most productions rarely use such heavily saturated colours. You’re more likely to notice it in games, where developers more often opt for more intense colours.

For testing we chose the "Film" mode and we think it’s by far the best of the available presets. There are none of the heavily boosted, unnatural colours you see in Vivid/Dynamic mode. The picture looks quite reasonable straight away, although it falls 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 tint, and a similar cast was visible in the greys. In HDR the situation was a little different. Here blue had a slight advantage, making the image a touch cooler. These are not major faults. For such an inexpensive TV the factory settings on our unit were pretty decent, and the "Film" mode already delivers a relatively natural picture without much fiddling with the settings.

To evaluate colours we of course used Filmmaker mode, and in SDR our S85H unit was set very well from the factory. The largest deviation appears in the white balance, where as brightness increases it starts to lose a bit of blue. In practice this means whites and greys have a slightly warmer tint than they should. However, it's not a big fault and during normal viewing it generally isn't very noticeable. Gamma also stays close to the reference value, so the picture is neither overly bright nor unnecessarily dim. The S85H's SDR picture therefore looks really good straight out of the box. A few more imperfections appear in HDR. Here the white balance shifts more with rising brightness, with blue starting to dominate and the red component clearly lacking. This also results in larger errors in some colours. These aren't yet colour errors that completely change the character of the picture, but in direct comparison with the 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 actually quite well prepared for picture calibration. The menu contains plenty of advanced picture settings that allow fairly precise adjustment of its characteristics. In our case the white balance required the most work, both in SDR and HDR. After correction SDR material looked very good. We managed to achieve an almost neutral white balance and natural colours, with the main limitation remaining the black level itself, stemming from the panel design and the lack of local dimming.

In HDR we were also able to improve white balance and colour reproduction, but here the TV’s electronics reveal their limitations more quickly. Even after very precise EOTF curve adjustment, the Q100 doesn't always stick to it properly during real-world scenes. In some content it can also brighten the image, making some parts look brighter than they should, and some detail in bright areas can be lost as a result.

Calibration delivers really good results on the S85H. First and foremost, we were able to set the white balance almost perfectly, which removes the slightly too-warm picture tone previously seen in SDR. Colour reproduction also improves significantly, with most errors falling to very low levels, and in everyday viewing it's hard to find any visible inaccuracies. You can also improve HDR quite a bit, although some issues remain that stem from the TV's inherent characteristics. The S85H doesn't always hold the luminance curve perfectly. The darkest parts are slightly boosted, while, as you approach the panel's limits, you can see small deviations in the brightest highlights. Add to that the limited coverage of the wider BT.2020 colour gamut, which of course cannot be overcome by any calibration. Despite that, the end result is very good, and after calibration the S85H can deliver a really well-tuned, natural image.

The weakest point of the Dreame Q100 is its digital image processing. The processor used does a fairly average job of improving weaker material, and the menu offers no function that effectively smooths ugly tonal transitions or reduces visible posterisation. The upscaling itself is also unimpressive. With low-resolution material the image is rather soft and lacks better reproduction of fine detail. Additionally, the Q100 tends to overscan, meaning it slightly crops the edges of the image with very poor sources, for example 480p material. In everyday viewing of HD or 4K content this won’t be a major issue, but with older recordings the processor’s limitations are clearly visible.

Samsung's S85H uses the same proprietary AI processor, AI NQ4 Gen2, as 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 doesn't come across as overly artificial. Just remember a common quirk of Samsung TVs: at very low resolutions you can't completely turn off overscan, so the TV may slightly crop the left edge of the picture. The "noise reduction" function, that is smoothing weaker tonal transitions, also works very well. The processor can effectively remove posterisation and other artefacts visible in lower-quality material. However, be careful with the strength of this function, because Samsung can be fairly aggressive here. When it's activated, along with unwanted artefacts, fine details such as skin or clothing texture also start to disappear.

The VA panel in the Dreame Q100 has a native refresh rate of 60 Hz, so right from the start it's not a television built for the most demanding sports fans or gamers. The manufacturer does note the option to run at 120 Hz and that mode is indeed available, but it's primarily intended for a gaming mode. In everyday use the Q100 should therefore be treated as a standard 60 Hz TV. That means less smooth motion during fast sports broadcasts or quick gameplay than in models with 120 Hz or higher panels. One positive is the panel's response time. The VA panel doesn't smear excessively, so motion stays fairly clear and doesn't leave strong, blurred trails behind objects. For films we can also use a simple motion smoothing system. The manufacturer has prepared several presets that help reduce the characteristic judder in material shot at 24 frames per second.

The S85H uses an OLED panel, so it performs brilliantly when it comes to motion blur. Pixels respond almost instantly, so moving objects don't produce the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sport or fast-paced games, where the picture stays very clean even during rapid motion. The panel itself runs at 120 Hz. That's more than enough for movies, TV shows, sport or console gaming. It's a shame Samsung didn't 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 doesn't affect motion handling in films or sport.

There's also the classic motion smoothing feature with two settings: blur reduction and judder reduction. So you can choose whether films should keep their cinematic 24 frames per second, or whether you'd prefer to smooth them a bit. The S85H gives plenty of freedom here, and the interpolation itself works well and, with sensible settings, doesn't generate too many artefacts.

Dreame Q100 is not strictly a gaming device, but for console use it offers a pretty sensible package. You get 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 120 Hz. The panel won't reach that refresh rate in 4K, but drop to 1080p and you can play at 120 frames per second. If a title prioritises smoothness over resolution (and the game offers such a mode), it's worth using. It also includes a handy Game Bar that lets you quickly change screen settings, switch the refresh mode or add a virtual crosshair. The HGiG implementation is a bit weak, but credit is due for Dolby Vision Gaming support on Xbox Series X and S. This isn't a panel for tech purists, but for casual console gaming, especially when trading 4K for smoother Full HD, it performs very well.

Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a computer. The manufacturer didn’t skimp on connectors 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 to plug your console into. With multiple devices that matters a lot, since you don’t have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very complete. The S85H supports VRR, FreeSync and automatic switching to Game Mode, and Samsung also offers its expanded Game Bar, which lets you quickly view the key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly for Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and it’s one of the features that has set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as large an increase in input lag as a classic motion interpolator. In practice, for slower-paced games, racing or action titles it can genuinely improve motion perception, especially if you’re sensitive to low frame rates.
