Samsung R95H Micro RGB vs LG OLED C6H (TANDEM OLED)

In terms of brightness the Samsung R95H shows that it is still a high-end TV, although the results are not always as spectacular as one might expect from a flagship Micro RGB model. In synthetic tests the TV can exceed 2400 nits, so it clearly has plenty of headroom. Crucially, it can maintain high brightness even when bright elements occupy a larger portion of the screen. In real cinematic scenes the situation is a little more complex. The R95H most often reaches around 1000–1400 nits, which still delivers a very good, powerful HDR effect. Bright sun, reflections or lights can look genuinely impressive, and the TV has enough power for HDR to be clearly distinguishable from standard SDR.

The problem appears mainly in very dark scenes with single, small light sources. Here the local dimming algorithm prioritises deep black and reducing halo over maximising the brightness of such elements. As a result, small highlights can be noticeably dimmed. Overall HDR therefore performs well, but not without limitations. The R95H has huge brightness headroom, especially in larger and brighter parts of the image, but in difficult dark scenes its capabilities are primarily limited by the way local dimming operates.

Colours

Colours were supposed to be the biggest revolution brought by RGB backlighting, and indeed the R95H shows considerable potential here. The assessment is not, however, as simple as synthetic measurements alone might suggest. On test patterns the TV performs superbly – BT.2020 coverage reaches almost 94%, and DCI-P3 98%, so particularly strongly saturated reds and greens can look truly impressive. The situation shifts somewhat when, instead of test patterns, we start measuring real film scenes. Then BT.2020 coverage falls to about 87%, and DCI-P3 to 93%. It seems that with more complex images the RGB zones are not always able to maintain the same high colour saturation as on simple charts. They remain saturated, but the advantage of the new backlight is no longer as large as the manufacturer’s figures might suggest.

And it is with HDR that the Tandem OLED panel shows its greatest advantage. The C6H’s brightness is simply very high and in our measurements it hovered around 1900–2300 nits in most film scenes. That’s already a level at which bright highlights, the sun or small light sources can look truly spectacular. The biggest impression, however, was made by the fifth scene from the film The Meg. It is exceptionally demanding for OLEDs because almost the entire screen is very bright. Even so, the C6H reached about 1650 nits in that scene. By comparison, the regular C6 with a classic WOLED panel recorded around 600–700 nits at the same point. So we’re talking about more than double the brightness, and in places the difference even approaches three times. And that is probably the best example of what Tandem OLED delivers here. It’s not just a higher result on a small test patch. The C6H can maintain very high brightness even when much more of the screen is lit. As a result HDR has significantly greater dynamism, and in this respect the C6H is much closer to flagship OLEDs than to typical mid-range models.

Colours

Tandem OLED also brings an improvement in colours. DCI-P3 coverage remains practically complete at about 99%, while in the much wider BT.2020 colour space we measured around 82–83%. That’s roughly seven percentage points more than the regular C6. In everyday use this won’t be a difference visible in every scene, because most films do not use such a wide gamut. However, when very highly saturated colours appear, the C6H already has noticeably greater capability, especially in reds. Reds benefit the most, becoming deeper and more saturated. This still isn’t at the level of the best QD-OLED panels or SQD TVs, but for a WOLED panel the performance is really very good.

For assessing factory colour reproduction we naturally chose the Filmmaker mode, the setting that is supposed to be closest to how the picture was intended by the creators. Here, unfortunately, the R95H does not fully exploit the potential of its panel. The biggest problem in SDR concerns the gamma. The image is noticeably brightened across almost the entire range, which makes it lose some depth and look flatter than it should. The white balance itself is also not ideal; as brightness increases there is a red bias and a lack of blue, making the image too warm. This is especially visible in bright elements and skin tones, which can look more "reddish" than they should.

It looks similar in HDR. The EOTF curve is above the reference value for a significant part of the range, so the R95H again brightens the image compared with how it should look. Combined with the inaccurate white balance, this means the colours here are also not as precise as we would expect from a TV of this class. The factory Filmmaker mode is therefore not the R95H's strong suit. At first glance the picture may look impressive because it is bright and highly saturated, but in terms of fidelity to the source material there is still plenty of room for improvement.

Straight out of the box the LG C6 is fairly well set up, especially if you select the Filmmaker mode. In SDR content the white balance is decent, although as brightness increases it shows a slight deficiency in red. The image therefore becomes a little cooler, but not enough for the difference to be very noticeable during normal viewing. More is happening in the brightness response. Gamma is a bit low and, instead of holding at 2.4, it sits closer to 2.1–2.2 across much of the range. In practice the C6 slightly brightens midtones. Shadow detail is therefore more readable, but the picture loses some depth compared with how it should look in a darkened room.

In HDR the situation is a bit more interesting. The lower end of the greyscale performs very well, but from roughly 20–30% brightness the white balance starts to drift increasingly. As brightness rises there is more red, while blue becomes noticeably deficient. In the brightest scenes the difference is already substantial and also affects the reproduction of some colours. The EOTF itself is, however, fairly well tracked across most of the range. The C6 merely tends to slightly brighten the image, which we already saw in our film comparisons. The largest deviation appears in the very brightest areas, where the TV begins to adapt the signal to the panel’s capabilities.

The factory Filmmaker setting in HDR is therefore not perfect, but overall it performs well. The biggest room for improvement is the white balance, particularly at high brightness.

The R95H responds very well to calibration. In SDR we managed to set the white balance and gamma almost perfectly, and colour errors fell to a very low level. The difference compared with the factory settings is therefore substantial and after calibration the picture looks noticeably more natural. In HDR we can also make considerable improvements, particularly in terms of white balance and overall colour accuracy. The issue of managing brightness and colour saturation is somewhat different, though. At a certain point we run up against limitations inherent in the RGB backlight and local dimming. Individual zones must control both the brightness and the colour of the light simultaneously, so in more demanding scenes it is not always possible to achieve exactly the same saturation and brightness that the TV shows on simple test patterns. Calibration simply cannot completely overcome that. Despite this, after calibration the R95H delivers accurate image reproduction, and most of the errors we saw on the factory settings can be effectively eliminated.

LG TVs have long been very receptive to calibration and the C6 is no exception. After adjustment the white balance could be set almost perfectly, and most colour errors fell below 3, often even down to around 2. In practice this means very accurate colour reproduction in both SDR and HDR. An interesting detail only emerged when we looked at the HDR luminance response. On a classic EOTF plot everything looks almost ideal and at first glance it would be hard to find fault. Only when we measured the TV's behaviour on filters based on real film scenes did it become apparent that the C6 has a slight tendency to artificially boost image brightness.

It is not a huge difference and many people may even welcome it because HDR looks a bit more striking as a result. From the point of view of fidelity to the source material this is not ideal behaviour though – some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is rather unusual for LG. In previous generations the brand's TVs typically stuck closely to the reference picture characteristic after calibration. With the C6 we are still very close to the standard, but this subtle brightness 'boost' can indeed be noticed in films and series.

The Samsung R95H uses the new Micro RGB AI Processor, but in practice we didn't notice a big leap compared with the NQ4 AI Gen2 or Gen3 chips found in Samsung's other TVs. The upscaling itself still performs very well. The image is smoothed appropriately, yet retains plenty of sharpness and does not look overly soft. That's definitely one of Samsung's stronger points. It's a pity that with very low-resolution material you still can't completely disable overscan.

The processor also handles colour gradation well and can effectively smooth unwanted posterization. The noise reduction function is really effective, but you need to use it with care. At higher settings it can start to interfere quite heavily with the image and even remove natural film grain. For that reason it's best used only when the source material is actually heavily compressed.

Here the LG C6 has taken a really big step forward. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That's a considerable plus, because this year's LG processor excels in that area. The "Smooth Gradation" function works particularly well. With heavily compressed footage it can effectively hide ugly banding and artefacts that often occur, for instance in lower-quality streaming. It's best to leave it on the "Low" setting. Then the improvement is noticeable, while the TV does not yet start to blur fine detail. Higher levels smooth the picture more, but can already remove some of the natural texture of objects on screen. Upscaling itself also performs very well. Lower-resolution material is sharpened correctly, edges look clean, and the processor quite effectively reconstructs fine detail. In this respect the C6 is already very close to LG's best TVs and the differences compared with the G6 are small.

Samsung R95H has a 165 Hz panel, so its motion handling is really good. At 120 Hz, for example when gaming on a console or watching sport, motion blur is minimal, and when connected to a PC you can use the full 165 Hz and further improve motion clarity. However, bear in mind it is still a VA panel, so it does not respond as instantly as OLED. You may sometimes notice a faint trail behind a moving object, but from a normal viewing distance this is unlikely to be bothersome. For films and TV shows you can also use the adjustable motion smoothing. You can keep the more cinematic 24 fps look or gradually smooth the motion if you prefer a smoother picture. Samsung gives plenty of flexibility here, so you can easily choose a setting to suit your own preferences.

The C6H with a Tandem OLED panel can also operate at refresh rates of up to 165 Hz. PC gamers will naturally get the most out of this, because for consoles, films or sport we're still looking at a maximum of 120 Hz. The panel itself is excellent when it comes to motion. OLED pixels respond virtually instantly, so even with fast-moving objects you don't see the typical motion blur. The picture remains clean whether you're watching sport or playing fast-paced games.

If you prioritise smoothness over motion clarity, TruMotion is available. LG lets you adjust two parameters separately. De-Judder mainly works with films and series shot at 24 fps and helps reduce the judder that's characteristic of them. De-Blur, meanwhile, is intended for 50/60 fps content, so it's particularly useful when watching sport or television.

In terms of gaming the Samsung R95H is almost a complete TV. When you connect a PS5 or Xbox Series X you can use 4K at 120 Hz, VRR and ALLM, and the TV also works correctly with HGiG. The only larger omission is Dolby Vision Gaming, which Samsung simply does not support, as with its other televisions. There is also the Game Bar, already seen on other Samsung models, which lets you quickly check the frame rate, VRR status or HDR format and change the most important settings without leaving the game. You can also brighten darker parts of the picture or change the screen aspect ratio.

Samsung also offers Game Motion Plus, a motion-smoothing function developed specifically for games. It makes most sense in titles running at 30 fps, where it can noticeably improve smoothness and make camera movement feel much more pleasant. You should remember, though, that this comes at the cost of higher input lag (about 60 ms), so it is probably not the best choice for online or more fast-paced games. It's also worth mentioning the Gaming Hub, which lets you run some games directly from the cloud without connecting a console. In terms of gamer-focused features, it is therefore hard to find any major shortcomings in the R95H.

The C6H offers practically the full suite of gaming features. On consoles you can easily use 4K at 120 Hz, while PC users can push the refresh rate up to 165 Hz. The TV also supports VRR from 40 to 165 Hz, ALLM and a proper implementation of HGiG. Dolby Vision is also available in game mode, which remains a major advantage for Xbox owners. All key information can be viewed in the Game Bar, which provides quick access to VRR settings and the current signal’s parameters. The OLED implementation therefore does not alter the feature set available to gamers, but with such high panel brightness HDR games can make an even stronger impression. Functionally, the C6H is simply a very complete TV for console and PC gaming.
