Samsung Q6F (IPS) vs Samsung R85H / R86H

The Samsung Q6F is, unfortunately, a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is a value that is decidedly too low to even talk about any effect of “high dynamic range,” or HDR. In practice, it’s better to stick to content in SDR format, which simply looks more predictable on this television. Another problem is the global dimming technique – in scenes with a lot of black, the television drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and the brightness can drop below 100 nits. The only consolation is supposed to be the QLED technology, but even here it is average. The layer of quantum dots used is not of the highest quality, as the coverage of the DCI-P3 colour palette does not exceed 90%. As a result, the colours in HDR content may simply appear under-saturated.

When it comes to brightness, the R85H performs really respectably. In most of our test scenes the TV reaches around 800 to 900 nits, and with larger bright elements it can exceed 1000 nits. These are not, of course, levels on a par with the pricier Mini-LEDs, but they are more than enough for watching films and TV shows in HDR, and the effect can already be quite noticeable. The problem reappears in more demanding scenes where there is a small bright element on a very dark background. Here the TV can significantly limit its brightness so as not to light up too large a portion of the screen. In our measurements such small highlights fell even to around 200 to 250 nits, so it is clear that a small number of zones combined with the particular behaviour of the algorithm has consequences here. Fortunately, this is not something that disturbs viewing all the time. In typical mixed HDR scenes the R85H looks good and can deliver appropriate image dynamics. It's just that with very small points of light you shouldn't expect an effect as strong as on TVs with many more zones or on OLEDs.

We tested the television in Filmmaker mode, which showed us two completely different facets of this model. Looking at SDR content, we were genuinely shocked at how good this television looks straight out of the box. It was really difficult to find fault with anything here. Despite a slight 'muddiness' in the white balance or somewhat brightened details in the blacks (which directly stem from the design of the IPS panel), the colour errors hovered around a level of '2'. This result is not only surprisingly good but downright amazing, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colours after switching to HDR mode was a very unpleasant surprise. The errors in colour reproduction and palette were so enormous that our charts literally ran out of scale. Of course, since Samsung even in such an affordable model offers very extensive calibration options, we decided to approach the issue professionally and see what could be done during calibration.

In Filmmaker mode our R85H sample performed acceptably in SDR, but a few things stood out immediately in the measurements. In the white balance red increased with rising brightness while blue decreased. As a result the brighter parts of the picture had a slightly too warm tint. Gamma only held to the target value at the start. It then gradually fell, which left most of the image a little too bright. The combination of these two effects also showed up in the colours, with errors growing particularly in the brighter and more saturated samples. It did not look bad, but for Filmmaker mode we had expected a bit more accuracy. Interestingly, in HDR our sample fared noticeably better. The white balance was much more even and, over most of the range, the individual components stayed close together. Only in the very brightest areas did red start to be lacking, causing white to shift subtly. The EOTF curve, by contrast, looked very good and followed the target luminance levels across almost the entire range. That does not mean HDR colours were perfect. The Colour Checker still showed some deviations, especially for some of the more saturated hues, but the errors were clearly smaller than in SDR.

After our calibration, the colours in SDR mode looked even better – the result is truly surprising, as colour errors at the '1' level are something generally seen in devices costing several thousand pounds. In this regard, the Q6F is really an excellent screen for everyday television, less demanding series or films. Unfortunately, our intervention in the HDR mode did not bring a noticeable improvement. The television, due to its poor blacks and low coverage of a wide colour gamut, still has significant issues with proper colour saturation, especially reds. This is an example of a device where HDR exists mainly as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

After calibration the R85H shows it has genuinely substantial capabilities in colour reproduction. It performed best in SDR, where the white balance could be brought almost perfectly into line and the gamma stays very close to the target value across most of the range. This also translated into very low errors on the Colour Checker, so there is really little to pick fault with. HDR also shows a clear improvement, although some things can no longer be corrected as well. At the highest brightness levels the character of the backlight begins to make itself felt and the individual components of the white balance start to drift apart. The same applies to the most saturated colours, which do not always land exactly where they should. Despite these limitations the overall image is much more accurate than with the factory settings, and the biggest difference is definitely seen in SDR. There is, however, one thing calibration cannot fix. With heavily saturated elements the colour can slightly bleed onto adjacent bright areas of the image. It is easiest to notice this on white, which can pick up a faint tint of a neighbouring colour. It does not appear in every scene, but when the material is demanding the effect can be visible. This is more a characteristic of the way the RGB backlight works than a matter of picture settings.

Q6F performs very well in upscaling lower-resolution content to native 4K. The scaling here is surprisingly good, even for such an inexpensive television from the QLED series. The only downside is the situation where we are watching very low-resolution materials, such as 576p (typical for old DVD players) – in which case the image may be slightly cropped. This is due to the fact that the television does not allow the Overscan function to be turned off, which is a typical issue with Samsung devices.

The situation is completely different when it comes to digital processing, specifically the attempt to smooth the image of unwanted artifacts. Here the television completely fails. Although there is a function in the menu called "Noise Reduction," it yields no visible results regardless of the slider setting. The only thing it manages to do is introduce undesired errors in the image. Despite its presence in the system, we definitely do not recommend using it.

In the R85H image processing is handled by the Micro RGB AI Processor. The name is new, but when it comes to upscaling lower-quality material the TV’s behaviour is very similar to what Samsung has shown before. And that’s not a bad thing, because the manufacturer has dealt with this aspect quite well for years. Lower-resolution content is displayed cleanly, edges do not become excessively soft, and the TV does not try to artificially extract details at any cost. The result is simply well balanced, and with regular broadcasts or older recordings the R85H performs as you would expect from a Samsung in this class. There remains only a minor drawback in the form of overscan, which cannot be completely turned off at the lowest resolutions. A separate matter is the additional processing of weaker sources. The R85H can smooth posterisation and somewhat tidy up heavily compressed footage, but it is worth emphasising that it does this relatively aggressively. At stronger noise reduction settings it begins to remove not only compression artefacts but also fine details and the natural film grain. It is therefore best used only when the material truly needs it.

The 60 Hz panel in the Samsung Q6F is standard for this price range, making it rather average for dynamic sports or gaming. However, when it comes to films, the television performs quite well thanks to the motion smoothing feature. The "Motion Reduction" option allows you to adjust the smoothness of movement to your own preferences – from maintaining a cinematic character to complete fluidity.

The R85H has a 144 Hz panel, so motion is really smooth here. Just bear in mind that the extra hertz above 120 are mainly used when connected to a PC, so in this category we don't treat them as any particular advantage. For films and TV, what's more important is that the panel is fast enough to provide access to an advanced motion-smoothing feature, "Motion Clarity", which lets you set motion anywhere from more film-like to very smooth. The panel's response time is a bit worse. Because it's a VA panel, fast-moving objects can leave a slight trail. On bright backgrounds this isn't very noticeable, but the darker the scene, the more pronounced the smearing becomes. This is a typical trait of this type of panel and it's easiest to notice in dark shots.

We're not going to beat around the bush – the Q6F is not a television designed for gamers. Although it features additions like ALLM (automatic low latency mode) and VRR frame synchronisation for consoles, the list of advantages basically ends there. Aside from these basics, the television offers nothing more that would satisfy those who spend a lot of time in front of a console. It’s a great shame that such a useful tool as Game Bar, which allows for quick control of game parameters in Samsung's higher models, is missing here. In terms of gaming, this model is absolutely basic and is only suitable for "casual" gamers.

Samsung has been steadily expanding its gaming features for several years, and the R85H really doesn't miss anything important here. The TV supports 4K at 120 Hz, VRR and ALLM, so we can easily take advantage of the PlayStation 5 or Xbox Series X. HGiG also works correctly, so with HDR properly set on the console, games retain the correct brightness and we don't unnecessarily lose detail in the brightest parts of the picture. The only major omission is Dolby Vision Gaming, which Samsung does not support on any of its TVs. The Game Bar is also very useful — a handy menu you can bring up without leaving the game. We can quickly check the frame rate, VRR status or change key picture settings. Samsung also adds a few less obvious features, such as the ability to change the aspect ratio and Game Motion Plus, which can further smooth games running at 30 or 60 frames per second. Of course this comes at the cost of higher input lag (around 55 ms), but for slower-paced titles it may be an interesting addition for some people.
