LG QNED93A / QNED90A vs TCL C7L

Although the number of local dimming zones in the LG QNED93A did not directly translate to a noticeably better contrast, one cannot deny that this model is brighter than its predecessor. In synthetic tests, we recorded values around 1400-1500 nits, and more importantly, these results are reflected in real movie scenes. In full-screen sequences flooded with white or bright lights, the screen was able to maintain high luminance, which produced a truly decent incredible HDR effect. Unfortunately, where the television could show its true class, namely in scenes that require precision, all the magic evaporates. The dimming algorithms we mentioned earlier are aggressive enough that small bright objects—such as distant lights, stars, or the moon—can almost completely disappear. Just look at the test scenes from the movie Pan or Sicario 2 (screens 2 and 4) to see how subtle details are dimmed to the brink of visibility. It's a shame, because a greater number of zones could theoretically lead to significantly better results. Fortunately, there are also stronger points. The QNED93A performs well in terms of color gamut coverage, achieving around 96% of the DCI-P3 standard. As a result, colors in movies look vivid and full, and the picture does not lose intensity even in more demanding scenes. So it can be said that the HDR in this model is solid, although the unfinished local dimming algorithms hinder its full potential.

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.

In movie mode (specifically Filmmaker), color reproduction on the QNED93A was relatively accurate, although it wasn't without critiques. In SDR content, white balance leaned towards warmer tones, resulting in a slight yellowing across the entire screen. Gamma, on the other hand, led to a slight brightening of the image, making it look a bit less natural, especially in scenes requiring precise shading (this is evident in the comparison picture). This isn't a problem that immediately stands out to every viewer, but more discerning individuals may feel that the picture deviates from the aesthetic intended by the filmmakers. In HDR materials, the situation looked somewhat different. The white balance presented itself quite well here, ensuring that whites didn't lean towards pink or unwanted shades of green. However, brightness management proved to be an issue. Analysis of the EOTF curve revealed that at certain moments the television can be noticeably too dark where it shouldn't be, losing some detail and reducing the realism of scenes. This detracted from the experience of HDR effects, which were theoretically supposed to be the most impressive. For this reason, we decided to carry out calibration.

When it comes to colors straight out of the box, a new feature in TCL televisions – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was previously unavailable from this manufacturer. By design, as the name itself suggests, the image in this setting is intended to be presented with the full intent of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful color reproduction straight out of the box. However, we definitely wouldn't say that it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode strayed into a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue color. Of course, for the average viewer, this may not be a drastic flaw, but if you care about perfect whites, natural skin tones, and fully unlocking the potential of these new "super" quantum dots, this television is in need of professional calibration.

After professional calibration, the Filmmaker mode on the QNED93A gained the most where it matters most in everyday use. It was possible to adjust the white balance and eliminate the yellowish tint in SDR content, which we watch most often – television, streaming services, or standard quality films. This makes colors look natural and pleasant, and the overall experience is much more comfortable. In HDR mode, we also made adjustments, but the biggest problem here turned out to be the EOTF curve. Although LG provides some leeway in the settings, the television still manages brightness on its own terms. It is evident that the local dimming algorithms are not entirely refined and can spoil the viewing experience by dimming parts of the image at inappropriate moments. Nonetheless, it is worth opting for calibration of this model, especially the mode intended for daily viewing.

After conducting a professional calibration, we managed to significantly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide color gamut dropped below the threshold of human perception – that is, below a value of 3, which is indeed a very good result. The TCL C7L definitely benefits from such an intervention in terms of color fidelity, and it's hard to dispute that. However, the management of brightness in HDR content post-calibration looks a bit worse. As I described earlier – even though we set up this model properly, when we turn on actual film scenes on the TV, it manages its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which is clearly visible in the EOTF graphs measured in specific films. Despite this defect – or rather a specific characteristic of this television – one cannot take away from it that after calibration, the C7L was able to reproduce the colors completely accurately.

LG QNED93A proves to be a very solid television for everyday use. Its image processor handles scaling excellently, ensuring that even older movies or terrestrial television gain sharpness and detail. During the screening of "The Godfather," it's clearly visible how upscaling pulls extra details from the image – the characters' faces and the texture of the clothing appear much clearer than in the original material.

The digital image processing also deserves praise. The television is equipped with a function for reducing unwanted color banding and screen irregularities. It works best in the "Medium" setting – subtly smoothing tonal transitions without over-interfering with the image. This way, the natural film grain is preserved, and the screen doesn't appear unnaturally smoothed. Perhaps in some scenes, you can still notice slight color banding, but in practice, the effect is more favorable than with a stronger intervention from the algorithm.

This point can be, in a sense, called the Achilles' heel of the C7L model. Unfortunately, this TV uses an older MediaTek chipset – the Pentonic 700 – which has never been known for exceptional digital image processing. This is clearly evident in the operation of the gradual smoothing feature, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – after setting it to low, its effectiveness is practically nonexistent. The only small plus here is that the algorithm doesn't spoil anything additional in the image and doesn’t forcibly blur details. The upscaling, that is, scaling the image from lower resolutions to 4K, performs a bit better. It is simply adequate and doesn’t stand out in any particular way compared to the competition. However, it cannot be denied that the C7L would gain significantly in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now increasingly found in many competitive models.

LG QNED93A is equipped with a 144 Hz panel. This is primarily a nod to gamers, but the fact that higher refresh rates are increasingly making their way into televisions can be seen as a positive development. In everyday viewing, 120 Hz remains key, and in this regard, the QNED93A performs well. The manufacturer also provides the option to adjust the image through the TruMotion system – the De-Judder and De-Blur sliders allow you to choose between a cinematic motion character with visible frames and a fully smoothed theatrical motion.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which can even ramp up to 288 Hz at lower resolutions when using a PC. These are, of course, very high values and commendable on paper, but in everyday life, it's worth remembering that nearly all dynamic content you display on this television will still be running around a maximum of 120 Hz. To harness this dynamics, we find a motion smoothing system in the TV's menu called “Motion Clarity.” It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-true guides on our YouTube channel. There we have two key sliders at our disposal. The first one, “Blur Reduction,” is responsible for reducing blurring and improving sharpness in dynamic 60fps materials, such as sports broadcasts. The second slider, “Flicker Reduction,” allows for the addition of artificial frames in movies and series recorded at cinematic 24 or 30 frames per second. This, of course, completely eliminates the irritating stutter effect during camera movement shots.

LG QNED93A is a television that has undoubtedly been designed with gamers in mind. Right from the start, we get a complete package – all four HDMI ports operate at standard 2.1, so whether we connect a console, PC, or receiver, we can be sure of full compatibility. This is important because many manufacturers still limit themselves to two ports, and here nothing prevents all equipment from having maximum capabilities. There’s also an automatic game mode (ALLM), which switches the television to the appropriate settings when the console starts up, as well as variable refresh rate (VRR). This ensures that the image does not stutter or tear, even when the frame rate drops – whether in dynamic shooters or during races.

The 144 Hz panel gives an additional advantage in computer games. While 120 Hz is sufficient for consoles, in the case of PCs, the QNED93A allows for even more – every movement, every glance to the side is refreshed faster, which makes a difference especially in e-sports. The manufacturer also considered HDR in games – the television supports the HGiG mode, which provides guidelines to ensure that the lighting effects are exactly as intended by the game developers. For dessert, we get Game Bar – a special informational strip invoked on the screen that shows parameters in real-time. You can check the frame rate, active VRR functions, or input lag levels. This solution is useful not only for settings enthusiasts, but for anyone who wants to quickly verify what mode the television is operating in and whether everything is working as it should.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, we have access to all the key features that console owners and powerful PC users require. It offers a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates impressively from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a well-designed gaming panel, the Game Bar, which even allows for customization of its appearance and theme to perfectly match the aesthetics of your console.

The only thing that can – and indeed must – be criticized here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home theater system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you will have to give up something or constantly juggle the cables at the back of the unit while maintaining convenient audio system control.
