Samsung U8000F (IPS) vs TCL C8L / QM8L

Better does not mean good – and that perfectly summarizes the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too little to enjoy any lighting effects. An interesting situation was noted during the measurement of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which are still weak). One could even suggest that the device uses some form of "global dimming," but unfortunately, the results are still very poor. To make matters worse, the television does not support a wide color gamut – the coverage of the DCI-P3 space is about 80%, so there’s no hope for truly vibrant colors. HDR images here look rather like lightly brightened SDR, and that's the form we would suggest sticking to when it comes to this television.

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 U8000F was tested in the best possible picture mode built into the TV, which is Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference-quality image without unnecessary enhancements. For SDR content (mainly HD/SD), the TV performed surprisingly well straight out of the box. White balance errors hovered around a value of 3, which is roughly at the threshold of perception. The only complaint could be about brightness management – the gamma chart showed a slight tendency to brighten or darken certain areas, but overall it performed quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance wasn't terrible, the TV had significant color errors – particularly noticeable on the Color Checker chart, where almost every sample landed outside the target point. The HDR image simply looks unnatural, and colors can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide color gamut (DCI-P3). The TV is physically incapable of displaying accurate colors in HDR standard – and this unfortunately shows in every more demanding material.

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.

Although the U8000F offered quite a decent picture in SDR right out of the box, we were able to adjust it a little more. We managed to eliminate a slightly purplish tint and calibrate the gamma to a more reasonable level. However, the television still tends to overemphasize the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is difficult to completely correct.

Unfortunately, the situation looks worse in HDR. It's hard to talk about any significant improvement here – the television is simply not designed for HDR content. We tried to adjust the picture in the advanced settings, but despite everything, the color errors remained quite large – a delta E above 7 indicates noticeable deviations. It's a bit of a shame, but that's the charm of a budget design. In SDR, the U8000F performs just fine, while HDR is simply not its league.

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.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup.

This year's model is equipped with a function to improve the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but even so – it can be confidently said that it works effectively.

However, not everything went perfectly. The U8000F has noticeable issues with slight frame cutting when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly “cut 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 U8000F is equipped with a 60 Hz panel, so right from the start, it’s clear that we shouldn’t expect any miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The TV offers one motion smoothing slider – a feature called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in movies. Higher settings provide a more "theatrical" and smoothed effect, while lower settings help retain the original character of the film with a slight 24p effect. Interestingly, there is a feature called "Clear Motion LED", which is a BFI mode – that inserts black frames between the frames of the picture to improve motion clarity. However, in practice, the screen flickers significantly when activated, and it should be regarded more as an experiment than something that realistically enhances gaming comfort.

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.

Samsung U8000F offers a basic set of features for gamers, which may still be sufficient for less demanding users. It includes an automatic game mode – when a game is launched on the console, the TV automatically switches to low latency mode, significantly improving response time. We also find the VRR feature, or variable refresh rate, which operates in the range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the “tearing” effect, as long as we stay within this range.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 range due to the release of software version 1131, which restored the HGiG feature, crucial for gamers.

And unfortunately, that's about it when it comes to advantages. Additional features like Game Bar or higher refresh rates are reserved for higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust HDR image settings to the intentions of game creators. Unfortunately – despite the fact that this feature appears in brochures and advertising materials – its configuration on the Xbox console turned out to be... impossible in practice.

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.
