Samsung QN990F vs Samsung S85H

Samsung QN990F is one of the bright televisions, and this is immediately apparent in tests. In measurements, it achieved around 1300 nits, which in practice allows you to enjoy films as their creators intended. Bright scenes have the right strength, lights shine, and the impression is truly cinematic. In standard test patterns, sequences number 1, 3, and 5 performed the best – there, brightness remained around 800-1000 nits, and the image looked very natural. In more difficult segments, it could dip to around 600 nits, but the level was still sufficient for details to be clearly visible. However, it should be added that with such highly contrasted shots, the halo effect returns – the same one we mentioned regarding blacks. Bright elements can leave a glow on dark backgrounds, and this is immediately noticeable. As we are dealing with a QLED, the colour palette is expanded, and the colours present themselves impressively. 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 gives an image that is vibrant and appealing; however, the competition in this and lower price ranges can show even more.

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.

We tested the QN990F in Filmmaker mode, which is the best out-of-the-box setting available. Right from the start, we noticed a few significant issues. The biggest problem was with white balance. Due to too little blue, as well as incorrect ratios 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 problems with brightness management—the TV struggled to maintain details in the smallest parts of the image, mainly due to how it manages backlight zones. Fortunately, Samsung provides plenty of room for adjustment when it comes to setting corrections. We know that with proper calibration, much more can be extracted from this screen.

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.

After carrying out the calibration, we managed to bring the white balance into order and eliminate the earlier shortcomings in shades of blue. As a result, the picture no longer looked like it had a slight yellowish filter – the whites are cleaner, and the whole thing presents itself much more naturally. We also managed to tame the brightness characteristic in HDR content to some extent. The television now handles maintaining detail in blacks much 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 accentuate details in dark areas 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 eliminate completely. Despite this, after calibration, the picture looks significantly more natural, mainly due to the correct exposure of white light. The final effect is definitely more pleasant to the eye and closer to what we expect from a flagship television.

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 QN990F deserves the highest praise for its upscaling capabilities. The processor responsible for 'lifting' classic TV to 8K resolution does a really decent job. Watching footage in 576p, we had no illusions that we would suddenly see a miraculous transformation like in an advertisement, where the image magically turns into crystal-clear 8K. Nevertheless, the final effect was surprisingly good; the picture looked clean and sharp. It's just a shame that the TV, like most Samsung models, has an overscan issue, which slightly cuts off the edges of the screen from the left side.

When it comes to image processing, Samsung offers a feature called "noise reduction," which in theory should improve tonal transitions in older materials, where they are usually more noticeable. Unfortunately, here we felt quite disappointed. The feature performs poorly – it struggles with unwanted banding and can even introduce its own artifacts. On the plus side, it’s worth noting that the TV doesn’t remove film grain when using this feature, but in practice, that’s a poor consolation when the noise reduction itself turns out to be practically useless.

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.

QN990F can easily be called one of the fastest TVs in the world. In 4K mode, it can display images at a frequency of up to 240 Hz, which until now was more associated with gaming monitors than with living room TVs. However, in everyday viewing, what's more important is how it handles an 8K signal at 120 Hz – and it performs very well here too. Motion remains smooth, and the TV handles even the most demanding content without breaking a sweat. Additionally, there's the motion smoother, or "Image Clarity." Thanks to this, you can adjust the picture to your preferences – leave it slightly cinematic with a bit of judder or switch to maximum smoothness, which works brilliantly for things like sports broadcasts.

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.

It has to be said straightforwardly – the QN990F is one of those televisions that scream they were designed with gamers in mind. Samsung has been developing its gaming solutions for years, but here we have a true package. Sure, it lacks Dolby Vision support in games, which is a downside that will always come up in discussions. However, aside from that, the list of features is truly impressive. To start, we have the Game Bar – a handy menu that allows you to quickly check and change game-related settings. You can see things like VRR enabled, frame rate, or aspect ratio settings there. It's like a little “dashboard” so you don’t have to dig deep into the menu to fix something. Since the word VRR was mentioned: yes, variable refresh rate is present here and works flawlessly. Plus, there's ALLM, which automatically switches the television 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 greatest impression comes from the number of ports. Four wireless HDMI 2.1 ports as standard is already great news, as there's no need to choose whether to connect the console, the receiver, or maybe even the PC. There's comfortably enough room for everything here. And if we add another micro HDMI (which we recommend connecting directly to the console), hidden within the casing, then in practice we have five inputs in full 2.1 standard. Let’s also add support for high refresh rates – 120 Hz in 8K or even 240 Hz in 4K – and we get a television that not only keeps up with the new consoles but also feels ready for consoles that aren’t even out yet.

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.
