Samsung QN990F vs Samsung S85H

The Samsung QN990F belongs to the bright televisions and this is immediately evident in the tests. In measurements, it achieved around 1300 nits, which in practice allows you to enjoy movies as their creators intended. Bright scenes have the right impact, lights shine, and the feeling is truly cinematic. In standard test patterns, sequences number 1, 3, and 5 performed the best – there the brightness remained around 800-1000 nits, and the image looked very natural. In more challenging segments, it could drop to about 600 nits, but still the level remained sufficient for details to be well visible. However, it should be added that with such highly contrasted shots, the halo effect returns – the same one we mentioned regarding the blacks. Bright elements can leave a glow on dark backgrounds, and this is immediately noticeable. Since we are dealing with a QLED, the color palette is expanded and the colors look impressive. The problem is that with such a flagship model, we expected better numbers. 91% coverage of DCI-P3 and about 67% BT.2020 are results that can be considered solid, but not outstanding. This results in a vibrant and attractive picture; however, competition in this and lower price segments can show even more.

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.

We tested the QN990F in Filmmaker mode, which is the best available right out of the box. Right from the start, we noticed several significant errors. The biggest issue was with white balance. Due to too little blue and also incorrect proportions between red and blue, the image – especially in scenes with a lot of white – appeared too yellow and at times even orange. On the Color Checker palette, these errors didn't look dramatic as they hovered around a value of 4, but in everyday viewing, especially with strong whites, they were most noticeable. We also noticed issues with brightness management – the television had difficulty maintaining details in the smallest parts of the image, mainly due to the way it controls the backlight zones. Fortunately, Samsung offers a lot of room for adjustment when it comes to setting corrections. We know that with proper calibration, you can definitely get a lot more out of this screen.

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.

After performing calibration, we managed to bring the white balance into order and eliminate the previous deficiencies in blue tones. As a result, the image no longer appeared as if it had a slightly yellowish filter – whites are cleaner, and the overall presentation looks much more natural. We also managed to some extent to tame the brightness characteristic in HDR content. The television now handles maintaining details in blacks significantly better and does not lose them as much as before. However, when we look at the EOTF curve and how the QN990F reproduces brightness in films, it is evident that it still tends to emphasize details in dark scenes more strongly. This is a characteristic feature of Mini-LED technology, and more specifically, how it is managed by the QN990F, which is practically impossible to completely eliminate. Nevertheless, after calibration, the image looks much more natural, primarily due to the correct exposure of white light. The final effect is definitely more pleasant to receive and closer to what we expect from a flagship television.

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 QN990F deserves the highest praise for its upscaling. The processor responsible for "pulling up" classic TV to 8K resolution performs quite well. While watching content in a 576p signal, we had no illusions that we would suddenly see a marketing-style miracle where the image magically transforms into crystal-clear 8K. Nevertheless, the final effect was surprisingly good; the image looked clean and clear. It's just unfortunate that the TV, like most Samsung models, has an overscan issue, which slightly cuts off the edges of the screen on the left side.

Regarding image processing, Samsung provides a feature called "noise reduction," which in theory should improve tonal transitions in older materials, where they are usually more noticeable. Unfortunately, we felt quite disappointed here. The feature works poorly – it struggles with unwanted bands and can even introduce its own artifacts. On the plus side, the TV does not eliminate film grain when using this feature, but in practice, that's little consolation since the noise reduction itself proves to be practically useless.

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 QN990F can easily be called one of the fastest televisions in the world. In 4K mode, it can display images at a frequency of up to 240 Hz, which until now has been more associated with gaming monitors than with televisions in the living room. However, in everyday viewing, what matters more is how it handles 8K signals at 120 Hz – and it performs very well here too. Motion remains smooth, and the television manages without a hitch even with the most demanding content. Additionally, there is a motion smoother, called "Picture Clarity." With it, you can adjust the image to your own preferences – leave a slight cinematic stutter or switch to maximum smoothness, which works great, for instance, in sports broadcasts.

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.

It must be said directly – the QN990F is one of those TVs that screams it was designed with gamers in mind. Samsung has been developing its gaming solutions for years, but here we have a true package. Sure, the lack of Dolby Vision support in games is a downside that will always come up in discussions. However, apart from that, the list of features is truly impressive. To start, we have Game Bar – a handy menu that allows you to quickly check and change game-related settings. You can see, for example, VRR is turned on, the frame rate, or the aspect ratio settings. It's like a small "dashboard," allowing you not to dig deep into the menu to make adjustments. Speaking of VRR: yes, variable refresh rate is present here and works flawlessly. Additionally, there's ALLM, which automatically switches the TV to game mode as soon as the console is turned on. These may seem like small details, but together they make using the QN990F simply convenient and hassle-free.

However, the number of ports makes the biggest impression. Four wireless HDMI 2.1 ports are already great news because you don't have to choose whether to connect the console, the receiver, or maybe even the PC. There's plenty of room here for everything. And if we add an additional micro HDMI (which we recommend connecting directly to consoles), hidden in the housing, we practically have five inputs in full 2.1 standard. Add to that support for high refresh rates – 120 Hz in 8K or even 240 Hz in 4K – and we get a TV that not only keeps up with the new consoles but also feels ready for consoles that are yet to come.

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.
