Dreame Q100 vs Samsung S85H

Unfortunately, the Dreame Q100 is too basic and, above all, too dim to be said to deliver a true HDR effect. Our measured brightness reaches a maximum of about 300 nits, which is definitely too low for bright parts of the image to truly pop. In fact, that’s a level we more often associate with SDR material than with HDR. It therefore lacks the brightness headroom offered by more expensive TVs that makes highlights, reflections, or the sun look noticeably more impressive.

HDR Colors

Fortunately the Q100 makes up for it a bit elsewhere. The manufacturer calls it a QLED TV, though in practice color gamut expansion is handled by a PFS filter. Our measurements showed roughly 92% coverage of the DCI-P3 color space and about 67% of BT.2020. These aren’t top-tier numbers, but they are still clearly better than basic LCD TVs without an additional gamut-expanding layer. As a result, HDR content can at least offer more saturated and varied colors, even if the peak brightness itself still doesn’t 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 the previous year's model stayed closer to about 700 nits, while the S85H can reach around 800 nits. Of course this isn't a change that completely transforms the HDR experience, but that extra headroom is noticeable especially with small highlights, 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 right impact. Bright elements can clearly stand out from perfect black, and that contrast still does most of the heavy lifting here. You should remember the typical limitation of organic technology, though. When a very bright scene covers a large part of the screen, brightness can drop by almost half. This is the result of the panel's protection mechanisms, which limit its power with large bright areas.

Colors

The S85H can produce very pleasant, saturated colors and in most HDR films it looks really good in that respect. We measured roughly 95% DCI-P3 coverage, so the palette most often used in movies is reproduced to a very large degree. Skin tones, greens, and stronger reds still have appropriate intensity, and during normal viewing it's hard to fault them. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was around 70%, a bit less than in previous-generation WOLEDs and noticeably less than in QD-OLED panels. In films this isn't a major loss, because most productions rarely use such highly saturated colors. You notice it more often in games, where developers are much more likely to employ more intense colors.

For testing we chose the "Film" mode and in our opinion it is by far the best of the available presets. There are no heavily boosted, unnatural colors you can see in the Vivid/Dynamic mode. The picture already looks quite reasonable out of the box, though it falls a bit short of perfect. In SDR material the most noticeable issue was a slight warming of the image. The white balance had too much red, so whites leaned toward a warmer tone, and a similar tint was visible in shades of gray. In HDR the situation was a bit different. Here blue had a slight edge, making the image a touch cooler. These are not major faults, though. For such an inexpensive TV, the factory settings on our unit were pretty decent and the "Film" mode delivers a relatively natural image without much fiddling with the settings.

To evaluate color we, of course, selected Filmmaker mode, and in SDR our S85H unit was very well calibrated out of the box. The biggest deviation appears in the white balance, where a bit of blue drops out as brightness increases. In practice this means whites and grays have a slightly warmer tint than they should. It's not a major error and during normal viewing it generally isn't 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 show up in HDR. Here the white balance shifts more as brightness increases, with blue becoming dominant and the red component noticeably lacking. That also leads to larger errors in some colors. These aren't yet distortions that completely change the character of the image, but compared directly 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 quite well equipped for image calibration. The menu contains plenty of advanced picture settings that let you adjust its characteristics fairly precisely. In our case most work was needed on the white balance in both SDR and HDR. After calibration, SDR content looked very good. We managed to achieve an almost neutral white balance and natural colors, and the main remaining limitation was the black level itself, caused by the panel design and the lack of local dimming.

In HDR we were also able to improve white balance and color reproduction, but here the TV's electronic limitations become apparent sooner. Even after very precise EOTF curve adjustments, the Q100 doesn't always follow it correctly during real scenes. In some content it can also brighten the image, making certain parts look lighter than they should, and in bright areas some detail can be lost in the process.

Calibration yields very good results on the S85H. First, the white balance can be set almost perfectly, which removes the slightly too-warm image cast that was visible earlier in SDR. Color reproduction itself also improves significantly; most errors drop to a very low level, and in everyday viewing it's hard to notice any visible inaccuracies. You can also improve a lot in HDR, although some issues remain due to the TV's inherent characteristics. The S85H doesn't always perfectly follow the brightness curve. The darkest areas are slightly boosted, and as you approach the panel's limits you can see small deviations in the brightest highlights. On top of that there's limited coverage of the wider BT.2020 gamut, which no calibration can of course overcome. Despite this, the end result is very good, and after calibration the S85H can deliver a well-tuned, natural image.

The weakest point of the Dreame Q100 is its digital image processing capabilities. The processor used does a rather mediocre job of improving weaker sources, and the menu doesn't include any function that effectively smooths unattractive tonal transitions or reduces visible posterization. Upscaling itself also fails to impress. With low-resolution content the image is fairly soft and lacks strong detail reproduction. Additionally, the Q100 tends to overscan, meaning it slightly crops the edges of the image with very poor sources, such as 480p content. In everyday viewing of HD or 4K content this won't be a major issue, but with older recordings the processor's limitations are already clearly visible.

For the S85H, Samsung used the same proprietary NQ4 Gen2 AI processor as in last year’s S85F, and in terms of digital image processing it performs quite well. Upscaling is one of this model’s strengths. Lower-resolution content is well sharpened, edges look natural, and the image doesn’t feel overly artificial. Just bear in mind a common Samsung quirk: at very low resolutions you can’t completely disable overscan, so the TV may slightly crop the left edge of the image. The "noise reduction" function, which smooths weaker tonal transitions, also works very well. The processor can effectively remove posterization and other imperfections visible in lower-quality material. However, you need to be careful with the strength of this feature, because Samsung can be fairly aggressive here. When it’s enabled, along with unwanted artifacts, fine image details such as the texture of skin or clothing can start to disappear.

The VA panel used in the Dreame Q100 has a native 60 Hz refresh rate, so from the outset this isn’t a TV aimed at the most demanding sports fans or gamers. The manufacturer does note the possibility of running 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 standard 60 Hz TV. During fast-paced sports broadcasts or quick gameplay this means less smoothness than models with 120 Hz panels or higher. On the plus side, the panel’s response time is decent. The VA panel doesn’t produce excessive smearing, so motion remains fairly clear and doesn’t leave heavy, blurred trails behind objects. For movies you 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 excellently when it comes to motion blur. Pixels respond virtually instantly, so moving objects don’t leave the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sports or fast-paced games, where the image stays very clean even during rapid motion. The panel runs at 120 Hz. That’s more than enough for movies, TV series, sports, or console gaming. It’s a bit of a shame Samsung didn’t include a higher refresh rate aimed at PC gamers, since more and more TVs now offer 144 or even 165 Hz at 4K. However, that doesn’t affect motion perception in films or sports. 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 if you prefer to smooth them a bit. The S85H gives you plenty of flexibility here, and the interpolation works well and, with reasonable settings, doesn’t produce too many artifacts.

Dreame Q100 is not a strictly gaming device, but it delivers a pretty reasonable package for console use. 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 a 120 Hz mode. The panel won’t reach that refresh rate at 4K, but if you drop to 1080p you can play at 120 frames per second. If a given title prioritizes smoothness over high resolution (and the game itself offers such a mode), it’s worth using. There’s also a handy Game Bar on board that lets you quickly change screen settings, switch the refresh mode, or add a virtual crosshair. The HGiG implementation is admittedly weak, but credit is due for support of Dolby Vision Gaming on the Xbox Series X and S. This isn’t a panel for tech purists, but for casual console gaming, especially with the option to trade 4K for smoother Full HD, it performs flawlessly.

The Samsung S85H is very well set up for gaming, whether you connect a console or a PC. The manufacturer didn’t skimp on ports and all four HDMI inputs 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 several devices that matters, 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 switching to game mode, and Samsung offers its comprehensive Game Bar, which lets you quickly view key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly to Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and is 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 large an increase in input lag as traditional motion smoothing. In practice, with more relaxed games, racing titles, or action games this can really improve perceived motion, especially if you’re sensitive to low framerates.
