Samsung Q7F vs TCL C7L

Unfortunately, the Samsung Q7F is not one of the bright televisions, and this directly affects the quality of HDR movies. The peak brightness of the panel is only about 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it hard to talk about any "wow effect" that usually accompanies us while watching such films. During testing movie scenes, the image simply looked dim, and brightness almost invariably hovered around the mentioned 250 nits. The worst performance was observed in shots with small, intensely glowing elements – the applied global dimming technique reacted very aggressively, dimming the entire screen to maintain the black effect. On the plus side, it is worth noting the presence of a QLED coating that expands the color palette. As a budget QLED model, the Q7F performs quite decently here: its DCI-P3 color coverage is about 93%, and BT.2020 reaches 70%. This means that colors, despite the low brightness, can look quite vivid and attractive.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness levels of around 2800 nits. This is an absolutely phenomenal result, considering the price range it falls into. Unfortunately, the tests with real film scenes are not as spectacular as the measurements of white squares. The brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as the vast majority of contemporary films are mastered at such a value. However, when small, pinpoint elements appear on the screen, the brightness of those details drastically drops – even to about 400 nits – which diminishes the HDR effect somewhat. The television does this intentionally to maintain a better level of black and prevent a huge glare of light. This is somewhat explainable, but it also shows that Mini LED technology is not completely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colors are obviously key here. And these, thanks to the use of new, "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve around 90% coverage of the ultra-wide color gamut BT.2020 and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such high color saturation regardless of the scene being displayed, which is often problematic in competing RGB Mini-LED televisions.

The factory color reproduction in the Samsung Q7F definitely isn't one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There's too much red on the screen, while blue is noticeably lacking. The effects of this are very easy to see – white, instead of being neutral, takes on warm, almost slightly orange tones. Over time, this makes the entire image look somewhat unnatural, and bright areas of the scene can seem unrealistic. The problems become even more apparent in HDR content. The graphs show that the TV has significant errors in the Color Checker palette, which translates to visible inaccuracies in the real image. In practice, this means that colors are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can appear dimmed. As a result, the image seems flattened, and instead of helping to bring out details, contrast only highlights its own limitations. This is particularly frustrating in HDR materials, as every detail matters there. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the brightening or, conversely, suppresses elements that were meant to draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we get more of a simplification effect.

When it comes to colors straight out of the box, what's new in TCL TVs, including the C7L model, is the addition of a picture mode called Filmmaker Mode. That's significant because until now that mode wasn't available from this manufacturer at all. In theory, as the name suggests, the image in this setting is meant to represent the filmmaker's full intent. From our tests we can confirm that it's without a doubt the best built-in mode on this TV if you care about faithful color reproduction right out of the box. However, we wouldn't say it's perfect. Like most devices on the market, this C7L also had some factory issues. The white balance in Filmmaker Mode tended toward a slightly greenish-yellow tint, caused mainly by an excess of the green channel and a noticeable lack of blue. For the average viewer this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and getting the full potential out of the structure of these new "super" quantum dots, the TV really begs for professional calibration.

After professional calibration, we managed to bring the Q7F in order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colors appear natural, and errors in the color palette have dropped to values that are practically invisible to the eye. The gamma behaves excellently, and the only minor drawback is a slight brightening of smaller elements, which results from the lack of local dimming. For everyday TV watching or standard quality films, the Q7F performs surprisingly well.

It was much more difficult to tame HDR content. Despite adjusting the white balance, the television continues to manipulate brightness significantly, causing scenes to sometimes look unnatural – what was meant to be subtly darker can end up being overly brightened, and bright parts of the image sometimes appear dull. The final effect is better than in the factory settings, but it is evident that the design limitations of the Q7F do not allow for fully utilizing the potential of HDR materials.

After a professional calibration we were able to greatly improve the out-of-the-box Filmmaker Mode. After our adjustments, errors in the ColorChecker test and across the wide color gamut fell below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L definitely benefits from this treatment in terms of color accuracy, and that's hard to argue with. A bit worse, however, is the issue of brightness management in HDR content after calibration. As I described earlier, even though we set this model up correctly, when you play real movie scenes on the TV it can manage its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which can be clearly seen on EOTF charts measured in particular films. Despite this flaw, or rather a specific quirk of this TV, you can't take away one thing: after calibration the C7L was able to reproduce colors accurately.

Upscaling and digital image processing in the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older movies or terrestrial TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it looks rather unrefined. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients remains. It's a bit disappointing because we could have expected more from a model that is aimed at users looking for a display for SDR content.

This point could, in a sense, be called the Achilles' heel of the C7L. Unfortunately, this TV uses an older MediaTek chipset, the Pentonic 700, which was never known for outstanding digital image processing. You can clearly see this in the operation of the gradual smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply performs very poorly; when set to low, its effectiveness is practically nonexistent. The only small plus is that the algorithm doesn't further degrade the image or forcefully blur details. Upscaling itself, meaning the scaling of lower-resolution content to 4K, performs a bit better. It's simply adequate and doesn't stand out compared with the competition. That said, there's no denying the C7L would gain a lot in this area if the manufacturer decided to use the newer Pentonic 800 processor, which is now appearing in an increasing number of competing models.

Motion blur and motion fluidity in the Q7F is probably the most budget-conscious element of this TV. The 60 Hz panel is noticeable, with blur being quite evident, especially in dynamic scenes, and it's rather difficult to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long tail, and the ball in a football match would leave trails behind it.

On the plus side, the presence of motion smoothing is commendable. It really makes a difference in movies - especially since most materials are recorded at 24 frames. Here we can decide for ourselves whether we prefer a more "cinematic" image, with the slight jerkiness characteristic of cinema, or a smoother, more "television-like" one. This actually works quite well and helps improve the viewing comfort for series or movies.

The TCL C7L uses a native 4K panel with a 144 Hz refresh rate, which, at lower resolutions when using a PC, can even reach up to 288 Hz. Those are obviously very high numbers and look impressive on paper, but in everyday use it's worth remembering that almost all dynamic content you play on this TV will still run at around a maximum of 120 Hz. To tame that motion, the TV's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode that we strongly recommend setting manually using our tried-and-true guides on our YouTube channel. There are two key sliders available there. The first, "Blur Reduction," reduces smearing and improves sharpness in dynamic 60-fps material, such as sports broadcasts. The second slider, "Flicker Reduction," lets you add artificial frames to movies and TV series shot at cinematic 24 or 30 fps. This, of course, allows you to completely eliminate the annoying image judder during camera motion.

Features for gamers in the Samsung Q7F is a topic that evokes quite a mix of emotions. On one hand, no reasonable person expected miracles here, as this is a 60 Hz television, and it was clear from the start that it wouldn't be equipment for extracting the maximum from consoles or PCs. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so you don’t have to manually fiddle with the settings, the console itself switches the television to low-latency mode. In addition, we have Game Bar, which looks impressive and allows you to view some basic parameters without leaving the game. And this is where the good news ends.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the key feature for gamers, HGiG.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, a relevant icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be activated in any way. It’s even more disappointing regarding HGiG; this option was actually available at the beginning, but after the software update, it completely disappeared, which is just unprofessional. Therefore, the Q7F is suitable only for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television that you buy with gaming in mind, and it’s better to be aware of that before making a purchase.

When it comes to gaming, the TCL C7L is simply an outstanding TV for gamers. Thanks to two full-bandwidth HDMI 2.1 ports at 48 Gbps, you get access to all the key features required by console owners and users of powerful PCs. It has a well-implemented ALLM mode with very low input lag and VRR frame-sync that works in an impressive range from 48 to 288 Hz. Importantly, unlike some competitors, TCL implemented the console HDR10 HGIG profile correctly and added support for Dolby Vision in games. Rounding out the package is a very well-designed player panel, the Game Bar, which even lets you edit its appearance and change the theme to perfectly match your console’s style. The only thing you can — and should — criticize is that the TV offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates a fairly significant logistical problem. Why? Because one of those fast ports also supports eARC (enhanced Audio Return Channel). In practice, that means if you connect a soundbar or a home theater system, you’ll only have one free HDMI 2.1 port left. If you have two consoles at home, or a console and a powerful PC, you’ll unfortunately have to give something up or constantly juggle cables at the back while trying to maintain convenient control of your audio system.
