SAMSUNG S95F (TANDEM OLED 83") vs TCL X11L

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also manages to enchant with HDR effects. In test film scenes, such as "Life of Pi" or "Sicario 2", where smaller light points dominate – stars in the night sky, the glow of the moon or headlights – the television effortlessly achieves brightness values exceeding 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and positions this model alongside the best Mini-LED constructions.

The limitations of organic panels only reveal themselves in full-screen scenes filled entirely with white. In the case of this model, for instance in the final scene from the film The Meg, brightness drops to around 1000 nits – a bit lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about a remarkable result, unprecedented in OLED televisions of this size. The colour reproduction is equally impressive. The new Tandem OLED panel virtually catches up with QD-OLED televisions, offering excellent coverage of a wide colour gamut. The results are slightly weaker than with QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

Such a large number of zones did not only result in deep, inky blacks, but also in screen brightness. The X11L is an extremely bright television. Peak brightness can easily exceed 4,000 nits, and with the special "Boost" mode active it can, in specific conditions, even reach marketing figures around 9,000 to 10,000 nits. It is undoubtedly one of the brightest, if not the brightest, screens on the market. So how do these numbers relate to real film measurements? The results are very good, though of course far from the marketing claims. The brightness we measured in real film scenes was around 2,000 to 3,000 nits. That is an excellent result, given that the vast majority of content available is recorded and produced for those brightness levels, even the rare material mastered to 4,000 nits. But it also clearly shows that the figures the manufacturer touts do not always translate directly to the video material you have at home. The only "quirk" (if you can call it that) is that when very small, bright elements appear on screen, their brightness falls below 2,000 nits. The dimming algorithm does this deliberately to preserve deep blacks and minimise halo. This is entirely understandable, and the effect is still very impressive, but it also shows that even with such powerful hardware, Mini-LED technology has its limits and does not always work without compromise. In HDR itself, brightness is not the only thing that matters; colour saturation and the colours themselves do too. On the X11L these are very good thanks to the new Super QLED (SQD) quantum dots. The application of a new coating filter has delivered excellent results in covering the P3 colour gamut and the ultra-wide BT.2020. Although it does not reach the promised 100% of BT.2020, figures around 89 to 90% can be considered excellent. Colours are not far off those of RGB Mini-LED screens. We can even say they are more stable, due to a less demanding algorithm that RGB screens often struggle with.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This is a mode that has been available in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, although not without faults. The image is slightly subdued, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. The average colour errors hover around a value of ΔE 3–4, which is at the limit of what most people can discern with the naked eye.

Much more pronounced are the limitations when it comes to HDR content. Here, a slight excess of blue in the white balance is not such a big problem – the real obstacle is the way the television manages brightness. In many scenes, the image appeared as if it had been overexposed, and details in the blacks could completely disappear. The final effect did not reflect what the hardware of this class is capable of and led to significant colour errors. It's hard to understand why such a factory characteristic was chosen, as the HDR reception in this version was definitely not what it should have been.

Turning on what should theoretically be the best Filmmaker Mode, you expect a one-to-one image of what the director saw. On the X11L it's fairly good, but this mode has obvious faults, which our measurements immediately exposed. Let's start with SDR. Both the white balance and the gamma are simply misaligned. The whites contain too much blue and red, giving the screen a slight pink tint. That also affected the gamma, which instead of holding the cinematic 2.4 drifts closer to 2.2. What did that result in? The whole image is therefore more pushed and looks artificially brighter. The worst comes at the end, namely the HDR measurements. Apart from this slight white-balance shift, the X11L fails on the brightness-management curve, the so-called EOTF. What we saw in the measurements immediately explains what we noticed earlier in films. The image is unnaturally brightened because the curve is massively overshot above the reference. The TV simply blatantly lifts the dark parts of the picture to create a "wow" effect, completely ignoring the director's intent.

After calibration, the S95F shows what it is truly capable of. The white balance has been corrected and minor inaccuracies adjusted, resulting in an almost exemplary image for SDR content. The colour differences have dropped below the level that the human eye can perceive – looking at the screen gives a sense of complete naturalness and colour coherence.

In HDR, the improvement is equally noticeable. The TV performs much better with brightness, eliminating the issue of "blowing out" the entire frame. Bright scenes are more controlled, and blacks retain more detail, although there can still be a slight brightening of the image as a whole. However, this does not change the fact that after calibration, the S95F delivers an image that can comfortably be called one of the best on the market – regardless of whether we are watching movies in SDR or spectacular productions in HDR.

After professional calibration we primarily managed to fully tame the SDR signal. Here the X11L responded perfectly to our adjustments. We were able to completely correct the white balance, remove that pink tint and set gamma to a stable 2.4. After that the picture finally became consistent with the director's vision, natural and free of artificial boosts. We also made minimal tweaks to HDR, but the TV's biggest flaw remained unchanged. It's of course about how the X11L manages its brightness and how much it overshoots the EOTF curve. Unfortunately, TCL provides virtually no tools to adjust this parameter. Even during professional calibration the software offers no way to rein in this curve, so the TV will always tend to brighten the image in HDR on its own.

In the Samsung S95F model, there is a noise reduction feature aimed at improving the smoothness of tonal transitions. Its operation can hardly be called ineffective – on the contrary, it can overly interfere with the image. Older films or materials of poorer quality, such as those from YouTube, acquire a soft, smoothed character thanks to it, reminiscent of a painting effect. The problem is that along with the noise, the natural film grain disappears, stripping the image of its cinematic character. Fortunately, the feature does not blur significant details, so its use is more a matter of taste. If someone prefers a slightly polished and smooth image, it is worth enabling, but in our opinion, the most sensible setting is “Standard”.

A better impression is left by the upscaling. The S95F efficiently enhances the quality of lower resolution content – even 576p video looks quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to competitors – such as the Sony Bravia 8 (II) or LG G5 – it is noticeable that those models can extract a bit more from the image. However, it is worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cutting off of the left edge of the image.

Much like the C8L model we tested earlier, TCL has delivered a substantial upgrade in its flagship X series. It's all thanks to the MediaTek Pentonic 800 processor used in this model. Thanks to it, features for smoothing tonal transitions and even upscaling content to higher resolutions finally look as they should. The biggest Achilles' heel of previous TCL models has at last been addressed. The processor handles digital processing superbly and, in this respect, the TV no longer lags behind flagship models from Korea or even the most refined ones from Japan.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion also makes a huge impression. The panel, with a native resolution of 4K, offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sports look superb. Additionally, the manufacturer has added a film smoother and a motion blur reduction system, allowing each viewer to adjust the image to their own preferences – whether it's a more "frame-rate" cinematic effect or a smooth, almost theatrical spectacle.

From a specification standpoint the X11L can impress, supporting refresh rates up to 144 Hz at 4K, and it can be pushed to as much as 288 Hz in Full HD. However, from a real-world usage perspective we were most interested in how the screen performs at 120 Hz. After all, that is the limit for today’s hardware, with current-generation consoles leading the way. How does that look in practice? Even though it uses a VA panel, the screen does not exhibit significant smearing. With very fast-moving objects you can notice a slight trailing, but it is subtle enough that it hardly stands out while gaming or watching sport. The motion smoothing feature called "Motion Clarity" is also very useful here, allowing you to adjust motion smoothness to your preference. Recommended settings can be found in the picture.

Low smearing and phenomenal motion fluidity, which are the hallmarks of OLED displays, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will experience the slightest limitation here. On board, there is a full set of gaming features: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), as well as a flawlessly implemented HGiG standard that allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's proprietary motion smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames per second, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is lacking, but it’s hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favourites for the title of the best gaming television on today's market.

For gamers the X11L is simply a superb screen. TCL has already accustomed us to the fact that it packs virtually every available feature into its products, and the flagship from the X series is no different. Thanks to the new processor, the X11L has as many as four HDMI 2.1 ports with full 48 Gbps bandwidth. Naturally, HDMI 2.1 brings a set of very useful features, such as Auto Low Latency Mode (ALLM) and VRR frame synchronisation, covering the full refresh range up to 288 Hz. All these features can be conveniently controlled from the dedicated Game Bar. Interestingly, its appearance can be customised to your taste; there are three preset themes to choose from, directly referencing the Nintendo, PlayStation and Xbox consoles. And speaking of Xbox, the X11L also supports Dolby Vision Gaming without any issues.

When gaming in the standard HDR10 format, however, you need to bear in mind the specific tuning of the brightness curve, which can prove troublesome during initial setup. Although the TV supports HGiG, configuring everything via the PlayStation or Xbox system menu can be difficult. The screen’s algorithms tend to artificially brighten the test checkerboard pattern, making it really hard to hit the correct white clipping point by eye. For HDR10 to look correct, we suggest manually setting the console brightness in the console menu to around 2,500–3,000 nits.
