LG OLED G5 vs TCL C7L

LG G5 with the new Tandem OLED panel brings the biggest change specifically in terms of the brightness of the television. And it’s quite impressive. This is truly an astronomically bright OLED. In every tested scene – whether it’s point lights or full-screen whites from the movie The Meg – the brightness on the G5 exceeded 2000 nits. Just a year ago, such values on an OLED were simply unimaginable. And here we are – the G5 comes close, and at times even surpasses the best Mini-LEDs on the market. A new feature of the Tandem OLED panel is the expanded color gamut coverage – and here the LG G5 performs almost perfectly. DCI-P3 achieves a full 100%, while BT.2020 maintains around 83%. These are some of the highest values currently available on the market – it’s hard to find any other television that comes close to such results, unless we are talking about the best displays with QD-OLED panels. The G5 has nearly reference-quality HDR – both in terms of brightness and color saturation. This is an OLED that can truly shine – and not just figuratively.

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.

Our test unit LG G5 struggled with some issues in the factory Filmmaker mode. And while the image might have seemed fine to most people, we knew that this TV was capable of much more. This mode had a clear excess blue tint in the white balance, resulting in a strong cooling of the image – particularly in HDR modes, where there was also a lack of red. The picture seemed cold, and its sharpness was artificially boosted and unnatural. Another significant issue was the brightness characteristic. In SDR content, the situation wasn't the worst, aside from a slight dimming of the entire image. However, it performed much worse in HDR materials – due to improper brightness management, the smallest details could completely disappear from the image, and larger, bright elements appeared overexposed and lacking gradation. Luckily, the G5 supports calibration using 3D LUT (a tool for professionals to calibrate colors), so we decided to take advantage of its professional background and see what it was really capable of. Because while it wasn't terrible even before calibration, the potential of this TV definitely deserved more.

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 completing the calibration process using professional tools, we can confidently state that the LG G5 offers nearly reference-quality image. Most of the errors related to white balance and the ColorChecker test are below the value of 2, which is a phenomenal result, practically imperceptible to the human eye. And while one could still criticize that in HDR films the television tends to slightly dim the smallest elements of the image, in practice, this does not negatively affect the overall impression. Hats off to LG, because once again they provide the user with enormous possibilities for adjusting their display – and this, combined with very good parameters of the panel itself, results in an image that is truly hard to surpass.

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.

Upscaling and digital image processing in the LG G5 perform very well. The television handles lower quality content exceptionally, especially when the "Smooth Gradation" feature is set to a low level. In this mode, it effectively removes unwanted artifacts and issues with visible tonal transitions. It may also slightly smooth out some desired details, such as the subtle texture of clothing or skin, but importantly – it does not remove film grain, so it’s hard to say there’s a serious compromise here. It’s one of those options that’s definitely worth enabling.

The G5 also does well with upscaling, which is improving the quality of older materials. The test image with the model looked really solid – slight edging was visible, but that’s an effect that can’t be completely avoided. Additionally, there were no issues with overscan, which – contrary to appearances – is not obvious, even in 2025.

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.

The motion fluidity on the LG G5 is simply phenomenal. The TV is equipped with a 165 Hz refresh rate panel, and this combined with the instantaneous response time of the OLED matrix delivers incredible results. The picture doesn’t stutter or smear like on classic LCD TVs. Like most LG models, the G5 features a motion smoother, which can be useful when watching movies – of course, we're talking about the TruMotion mode. With the “De-Blur” and “De-Judder” sliders, we can adjust the smoothness of older material according to our preferences, whether we want to preserve the characteristic film stutter or move towards a more fluid, television-like effect.

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.

Features for gamers? Perfect. That should be enough for you to know what level we are dealing with here. G5 is a television designed with gamers in mind, so we find literally everything one can expect from a gaming screen. There is Game Bar, support for high resolutions with high refresh rates – that is, 4K at 120 Hz, and even more, because the panel has a refresh rate of 165 Hz (which PC gamers will benefit from). The television supports variable refresh rates (VRR), automatic low latency mode (ALLM), and correctly supports HDR in games thanks to HGiG. All of this adds up to one of the best sets of gaming features available on the market. Well done, LG.

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.
