LG OLED G5 vs TCL V6C

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.

When it comes to HDR, the TCK V6C clearly shows that it is not its strong suit. Peak brightness around 200 nits makes it difficult to talk about true HDR effects – the image simply remains too dark to extract details in bright scenes or convey the appropriate dynamics. Although the TV formally supports many HDR formats, in practice it is not adapted for such demanding content. The lack of additional coatings that enhance colors, such as QLED or PFS LED, further limits the appeal of the image – in more spectacular productions, colors may seem washed out compared to more expensive models. Therefore, the V6C will primarily serve as a television for everyday TV, YouTube, or SDR materials, rather than as equipment for high-quality cinematic experiences.

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.

We started the color reproduction tests with the Filmmaker mode, which in theory should be the best choice right after taking the television out of the box. It certainly performs better than the Eco or Dynamic modes, which heavily interfere with the image and spoil its natural character. As you can see in the charts, the factory tuning of the V6C is not ideal, although it’s not a disaster either. The biggest problem turned out to be a lack of red – the television clearly "cools" the image, which is particularly noticeable on human faces, giving a "corpse skin" effect. This issue was the most bothersome in daily viewing. Looking at the color palette in HDR content, the deficiencies in red are also noticeable, and their source is the relatively narrow coverage of the color space. Of course, every television can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

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.

My dear friends – we haven't had such a difficult "calibration battle" in years. The V6C turned out to be one of the most stubborn TVs we've dealt with in the editorial office. The calibration trials alone took us several working hours and required a lot of patience. We finally managed to slightly warm up the skin tones, which made the faces stop looking like they were straight out of a horror film, a flaw in the factory settings. Unfortunately, that's not the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable way. Where we expected image stabilization in a given area, new errors appeared, and the Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the software or the construction itself was to blame, but one thing is certain – the V6C offered exceptionally strong resistance. In the end, the calibration brought improvement, especially in SDR content, where the image became more pleasant and natural. However, it must be clearly stated that the design limitations remained. The TV still flattens the image in HDR material and has significant deficiencies in color reproduction. This is equipment rather intended for everyday TV watching or SDR materials than for cinematic screenings in the highest quality.

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.

When it comes to upscaling, the V6C does not bring anything groundbreaking. Lower quality content is heavily sharpened, making the image look very unnatural, sometimes even artificially. This can be partially mitigated by lowering the sharpness level in the settings, but the effect is not spectacular. The image still remains far from ideal. The digital processing itself performs better. The function responsible for smoothing tonal transitions works quite effectively, especially at the medium setting, where the image indeed appears smoother. Unfortunately, its operation is quite aggressive – it heavily interferes with the overall scene, causing the actors in the foreground to start looking like characters from super smooth telenovelas. Therefore, we would not recommend using this option if natural reception of the image is important to us.

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.

Motion smoothing and motion fluidity is an area where the V6C quickly reveals its limitations. It is a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the picture comes off rather average. This is most noticeable in darker scenes, where clear smears and blurry "halos" trail behind moving objects, which can be quite distracting. This is definitely a weaker point of this model. Fortunately, there is also a small plus. The V6C is equipped with motion interpolation, which works while watching movies. Thanks to it, productions recorded at 24 frames per second, meaning practically all cinematic titles as well as series, can look smoother than they were actually recorded. Importantly, the intensity of the effect can be adjusted to personal preferences – from slight smoothing to full "soap opera effect."

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.

Although the V6C is not a television designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. There is no 120 Hz panel or HDMI 2.1 ports, but there is an ALLM mode that automatically switches the TV to low-latency mode. Additionally, there is a quite practical Game Bar – a simple panel that allows you to view basic parameters, change the picture mode, or even enable a virtual crosshair on the screen. An interesting feature is also the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, though in practice it doesn't offer as much as in more expensive models. However, the biggest problem remains HDR configuration. The HGiG feature, which adjusts the brightness and contrast of games to the panel's capabilities, does not respond as we would expect – the image can end up being overly dark or too flat. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C performs stably and does not try to pretend to be an HDR TV.
