Samsung Neo QLED QN95D vs TCL C8L / QM8L

The Samsung QN95D excels in HDR performance, achieving an impressive peak brightness of approximately 2000 nits. In tested movie scenes with fully lit screens, the television delivers an intense and realistic representation of HDR content, significantly enhancing the viewing experience. However, as with its handling of contrast, the dimming algorithm occasionally reveals limitations.

Despite the large number of Mini LED zones, the television doesn’t consistently provide extraordinary brightness. For instance, in scenes from "Life of Pi," featuring a bright moon against a dark background, and excerpts from "Sicario 2," showcasing intense light effects on dark backdrops, the QN95D underperforms. In such instances, the television mitigates halo effects by dimming the image to a level closer to SDR quality. While this ensures deep and uniform blacks, it comes at the cost of losing some detail in bright areas. This compromise is intended to preserve black quality but can detract from the image’s dynamism.

Despite these occasional shortcomings in the local dimming algorithm, the QN95D deserves commendation for its wide coverage of the DCI-P3 colour gamut. Thanks to the quantum dot coating, also known as QLED technology, the television produces vibrant and richly saturated colours, adding to its appeal for HDR content.

In terms of HDR, the TCL C8L turns out to be a hellishly bright television – and I mean literally. On a synthetic chart of 5%, our measuring equipment indicated a result exceeding 4500 nits. This is a result that is downright cosmic, considering that reference director monitors, which we often refer to in our materials, typically operate around 4000 nits. Does this mean that the C8L breaks barriers and climbs to the technological peak of Mini-LED? Not exactly. Dry synthetic tests are one thing, and real movie images are another. In real, varied scenes, the C8L achieves a peak of around 1600 nits. This is still a very good result, ensuring a very high level of HDR dynamics, but also clearly lower than what the manufacturer boasts in the specifications. The trouble starts with very small flashes of light – then brightness can drastically drop to around 600 nits. The algorithm tries at all costs to maintain deep black and minimize halo effect, but it does so at the expense of HDR impact. This is perfect evidence that laboratory charts rarely correspond to what we ultimately see on the screen.

Huge applause is due for color reproduction, all thanks to the new generation of SQD (Super Quantum Dot) quantum dots. The coverage of the DCI-P3 palette reaches 97%, but the true jaw-dropper is the measurement of the extremely demanding BT.2020 space. The C8L achieves as much as 90% in it, placing it alongside today's top screens that boast RGB backlighting. Importantly, unlike some screens with Micro/Mini RGB backlighting, this effect is stable regardless of the scene displayed. Of course, one must remember that content mastered for such a wide gamut in films or series is still a rarity. However, the mere fact that the panel has such a "color reserve" deserves immense admiration.

The Samsung QN95D was evaluated for factory colour reproduction in Filmmaker mode, which provides the manufacturer’s optimised settings. While this mode delivers good performance, it is not without shortcomings. For HD content, notable colour deviations were observed, particularly in white balance, where a red tint dominated the chart. Improvements were noted with 4K HDR content; however, significant deficiencies in blue colour reproduction persist. This is evident in scenes such as those from Star Wars, where the main character appears in tones that are warmer than intended.

Regarding contrast, the gamma chart reveals an initial steep rise, demonstrating the television’s capability to emphasise brighter image areas effectively. However, the chart also shows a clear dip at the lower end, suggesting a potential loss of detail in darker tones. This gamma curve shape could impact the clarity of dark scenes, where details may appear overly blurred or obscured. Additionally, the brightness curve (EOTF) was mostly accurate, aside from an initial drop.

Despite these minor issues, the QN95D boasts impressive features and cutting-edge technology that solidify its position as one of the top televisions on the market. However, refinements in colour accuracy and contrast are needed to maximise its potential fully.

We tested the TCL C8L in the best factory picture mode available in this TV’s menu for image fidelity. That, of course, is Filmmaker Mode, which appeared in this brand’s software relatively recently (a year ago in the "K" series). Thanks to it, an average user can get a pretty good color reproduction straight out of the box, although it is certainly not a perfectly tuned mode. Looking at the factory white balance of our unit, both in SDR and HDR material, the red component was clearly lacking, which made the image noticeably cooler and caused a slight shift toward bluish-green tints. The issue of brightness management is also ambiguous, as we mentioned earlier. While for SDR content the gamma linearity is actually correct and holds steadily at the reference value of 2.4, in HDR things look much worse. Tracking the EOTF curve clearly shows the TV has a significantly boosted brightness across the range, which can make the final image overly bright and inconsistent with the creators’ intent, and that in a mode that by definition should avoid that. Of course, like every sample in our lab, this one also underwent professional calibration, and its results are shown below.

After calibration, the Samsung QN95D delivers truly impressive results. The white balance is perfectly aligned, with error readings rarely exceeding 2, indicating faithful colour reproduction. Most samples from the Colour Checker test fall well within an acceptable error range, confirming the television's excellent performance in accurately displaying colours. Contrast has also improved significantly, and the gamma curve has become more stable, ensuring better visibility of details in both dark and bright scenes.

However, the EOTF (Electro-Optical Transfer Function) curve still shows a slight divergence in film tests. While the television performs well in most scenarios, some details in black may still be lost in extreme cases due to the aggressive dimming algorithm.

Despite these minor imperfections, the overall image quality remains outstanding. After calibration, the Samsung QN95D impresses with its visual performance, offering an exceptional experience that will satisfy anyone seeking a top-tier television.

As you can see, the results of a professional calibration of the TCL C8L are really promising, thanks to the extensive adjustment tools the manufacturer put at our disposal in the menu. Above all, we were able to completely correct the white balance — we eliminated the red deficiency, so the image finally stopped drifting toward unwanted cool tones. After that adjustment, errors in the ColorChecker test fell to near-reference levels, regularly landing below a Delta E of 2, which is below the threshold of human perception.

If the test patterns look this perfect, you might ask: why then the lower final score in this category? The answer lies in the brightness management discussed earlier. Although the menu includes sliders that let you precisely straighten the EOTF curve on synthetic signals, when confronted with actual movie material (I recommend enabling the EOTF filter when watching movies), you can see that in most scenarios the TV still reacts to HDR metadata its own way. As a result, the picture can be slightly over-brightened and not faithful to the creators' intent, and it was precisely this lack of consistency with real films that cost the C8L a few points.

The Samsung QN95D television handles tonal transitions even in lower-quality materials, thanks to the noise reduction feature that works like a gentle gradation. This function is extremely effective, smoothing out the image and eliminating unwanted noise, thus significantly improving the quality of the displayed material. However, as is often the case, overly good effectiveness can lead to unintended side effects. In the case of some materials, this feature may also blur elements that should remain clear, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jagged edges. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural look, and the model does not have an artificial outline. Overall, even in more challenging conditions, the footage is presented satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (such as regular terrestrial television) is the fact that the image is slightly cropped - this is caused by the so-called overscan, which cannot be turned off.

This year the C8 series and higher models received probably the biggest and most anticipated upgrade in TCL’s history, and it specifically concerns digital image processing. The C8L is the lowest-end model in the manufacturer's lineup to be equipped with the latest flagship chip, the MediaTek Pentonic 800 (listed in the menu as MT9655). Thanks to its processing power, the feature called "Gradual Smoothing" finally works as it should. The algorithm effectively eliminates unwanted posterization (ugly tonal transitions/color banding), doing so intelligently enough that it does not degrade the sharpness of other details.

The processor also handles upscaling lower-resolution content to 4K very well. Although evaluating this element can be mostly academic, because the differences between today's TVs in this class are very subtle. The most important takeaway is that TCL finally has nothing to be ashamed of compared to the competition.

The Samsung QN95D panel excels in motion blur and fluidity, offering a 120 Hz refresh rate along with features designed to reduce blur and judder. This allows users to adjust the picture settings to their liking, whether for movie watching or dynamic sports broadcasts. The television provides a 10-point scale for adjusting image smoothness, ranging from a frame-like appearance reminiscent of traditional film to a smoother, more cinematic effect, which is especially beneficial for sports broadcasts. This level of customization enhances the viewing experience across various types of content.

The TCL C8L is equipped with a fast panel that has a native 144 Hz refresh rate. That spec will be most appreciated by demanding PC gamers, while most users, who rely on consoles or TV broadcasts, will use a steady 120 Hz. It is at 120 Hz that motion processing algorithms handle image rendering for movies, series, and sports. In the TV’s menu you’ll find a "Motion Clarity" option that lets you adjust the motion smoothing to your preferences. The algorithms handle cinematic material at 24 or 30 frames per second (fps) as well as dynamic sports broadcasts at 50 or 60 fps, maintaining appropriate smoothness.

The Samsung QN95D offers several features that gamers will appreciate. First, the TV supports a variable refresh rate (VRR), which eliminates screen tearing and provides smoother gameplay, especially in dynamic scenes. It also includes an automatic game mode (ALLM) that switches the TV to low latency mode when a connected console or computer is detected, resulting in more responsive controls.

Additionally, the QN95D has a game mode that reduces input lag to an impressively low level, which is vital for games where quick reflexes matter. With a high refresh rate of 120 Hz, the image remains exceptionally smooth, enhancing the experience of fast-paced action games and sports. The TV also supports G-Sync and FreeSync technologies, further improving gameplay and user comfort. An interesting addition is the 'Game Bar' – a special menu that provides easy access to all gaming-related settings, allowing users to quickly adjust the image and other parameters without interrupting gameplay.

While the Samsung QN95D does not support Dolby Vision, which is typical for Samsung models, it does feature HGiG functionality, ensuring that HDR games are displayed with the appropriate image quality in line with the creators' intentions.

For gamers – especially for those with powerful PCs and several consoles at the same time – the TCL C8L is a true beast. It’s the first model in the manufacturer’s lineup equipped with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This is directly thanks to the new Pentonic 800 processor we wrote about earlier. Additionally, the TV seamlessly supports virtually every gaming feature. It has an automatic game mode (ALLM) that reduces latency to minimal levels and full frame synchronization (VRR) operating in an impressive range of up to 288 Hz. We’re also talking about standards like G-Sync or FreeSync from Nvidia and AMD. When it comes to image display standards, there are also no compromises: the C8L offers complete support for HDR formats in games, including gaming Dolby Vision and the HGiG profile. All of these features can be conveniently managed from a very readable game bar (Game Bar), which we can customize according to our preferences. From a purely gaming perspective, there really isn’t anything to complain about in the C8L – well, maybe aside from the previously mentioned slight ghosting. But other than that? It’s an unflawed machine for gamers.
