Hisense A6N vs LG OLED C6 (WOLED)

Unfortunately, the HDR effect quality on A6N is not impressive. A peak brightness of 250 nits doesn’t allow for spectacular highlights, and HDR looks rather muted, more like ordinary SDR. This will not satisfy more demanding users who want to enjoy high-quality movie content. Additionally, the color gamut coverage is not very impressive either: DCI-P3 at 82% is an average result that doesn’t let you fully enjoy vivid colors in HDR material.

The HDR effect on the LG C6 is really very good. LG Display's new WOLED panel primarily brought a significant increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can show similar values in many normal movie scenes. That gives HDR the proper impact. Bright highlights, lamps, or sunlight can be really strong, and most HDR movies simply look very impressive. Of course it's still an OLED, so brightness drops in scenes with a lot of white. The fifth scene of The Meg illustrates this well, where the C6 reached about 600-700 nits. That's still a very good result, but it also shows the new panel hasn't removed all the limitations typical of OLEDs.

Colors

When it comes to color, there is also little to complain about. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice the colors are very saturated and, importantly, stable regardless of the scene. That's worth emphasizing, because not every TV behaves the same in this respect. In some RGB Mini LED models color saturation can depend more strongly on image brightness. Today a wider color gamut is mainly offered by QD-OLED TVs and new SQD models with a new generation of quantum dots. However, the C6 still performs very strongly here and is able to generate appropriately saturated colors in most movie scenes.

In the color reproduction category, the Hisense A6N in Filmmaker Mode leaves much to be desired. Although the mode's name suggests we should expect faithful movie color reproduction, the reality is different. The TV has significant picture quality problems. The white balance issue is particularly noticeable for both HD and 4K material, as it is heavily skewed by a dominance of blue. This results in artificial, cool tones, clearly visible in the comparison photo below. The ColorChecker test further confirms these errors, which are compounded by low color gamut coverage.

The gamma luminance curve shows a serious problem maintaining the 2.4 level, with the plot well below the reference value. That leads to excessive image brightening and washed-out blacks. The EOTF curve for 4K material also indicates brightness problems. At the low end there is a pronounced bump caused by the TV's excessive brightening, which negatively affects picture quality. This image behavior prevents fully enjoying movies and requires manual correction.

Right out of the box the LG C6 is pretty well set up, especially if you choose Filmmaker mode. In SDR material the white balance is decent, although as brightness increases it starts to lack a bit of red. The picture becomes a little cooler as a result, but it’s not such a big difference that it stands out during normal viewing. More happens in the brightness response itself. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 over much of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses some depth compared with how it should look in a dark room. In HDR the situation is a bit more interesting. The start of the grayscale looks very good, but from about 20–30% brightness the white balance starts to drift more and more. As brightness rises there’s more red and a noticeable lack of blue. In the brightest highlights the difference is already significant and also affects reproduction of some colors. The EOTF curve itself is handled fairly well over most of the range. The C6 only has a tendency to slightly brighten the image, which we also saw during our film comparisons. The largest deviation appears around the brightest highlights, where the TV begins to adapt the signal to the panel’s capabilities. So the out-of-the-box Filmmaker mode in HDR isn’t perfect, but overall it performs well. The biggest room for improvement is the white balance, especially at high brightness.

Hisense A6N offers in its settings options and tools to adjust many picture parameters, which we used. As for the white balance, we managed to remove the excess blue; this is clearly visible in the comparison photo below, where the boy in the image practically "comes to life". A large improvement can also be seen in the gamma brightness response, as the TV no longer has serious issues with overbrightening the entire picture. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to this model's exceptionally low brightness. For HDR content we use dynamic tone mapping, which allows recovery of many details despite lifting the midtones. For this TV that brings more benefits than drawbacks. The errors that remain visible in the color gamut test and the ColorChecker for 4K content stem from the low color gamut coverage and are difficult to eliminate because of the TV's characteristics. Even so, the image tonality is much better, so we recommend calibrating the factory settings, which are far from ideal.

LG TVs have been very receptive to calibration for years, and the C6 is no exception. After adjustment the white balance was set almost perfectly, and most color errors dropped to values below 3, often even around 2. In practice this means very accurate color reproduction in both SDR and HDR. An interesting detail appeared only with the HDR brightness characteristic. On a classic EOTF chart everything looks nearly ideal, and at first glance it would be hard to find fault. Only when we measured the TV’s behavior using filters based on actual movie scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

It’s not a huge difference and many people may even see it as a positive, because HDR looks a bit more impressive this way. From the standpoint of fidelity to the source material this isn’t ideal — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is somewhat unusual for LG. In previous generations, the brand’s TVs typically stuck very closely to the reference tone curve after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness is indeed noticeable in films and series.

Let's see how A6N handles low-quality material. When it comes to smoothing tonal transitions, the lack of a function to reduce posterization or smooth tonal transitions in low-quality sources, such as broadcast TV or DVD, may be noticeable to more demanding viewers. As for digital processing, the model was rendered correctly and the branches were free of the typical jagged edges. The image has a pronounced sense of plasticity and is soft, which may appeal to those who prefer that kind of picture style.

The LG C6 has taken a really big step forward here. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That’s a big plus, because in this area LG’s processor this year performs excellently. The "Smooth Gradation" feature works especially well. With heavily compressed material it can effectively hide ugly tonal transitions and artifacts that often appear, for example, in lower-quality streaming. It’s best to leave it set to "Low." Then the improvement is clear, and the TV doesn’t yet start blurring fine details. Higher levels smooth the image more, but can already remove some of the natural texture of objects on the screen. The upscaling itself also performs very well. Lower-resolution content is sharpened properly, edges look clean, and the processor quite effectively rebuilds fine details. In this regard the C6 is already very close to LG’s best TVs, and the differences compared with the G6 are small.

The 60 Hz panel in Hisense A6N will likely please people who enjoy watching movies, because the TV offers an "ultra motion smoothing" feature that lets you adjust the image's motion, making it choppier or smoother and more cinematic. As for motion blur, it is rather average. You can see quite noticeable blur, especially on dark backgrounds, which is a common trait in this class of TVs.

The LG C6 features a panel with a maximum refresh rate of 165 Hz, which is great news especially for gamers using a powerful PC. For movies, sports, or consoles we'll of course use up to 120 Hz, but even then it's hard to fault the motion clarity. As you'd expect from an OLED, the panel's response time is almost instantaneous. Moving objects therefore don't leave the characteristic smears you still see on LCD TVs. This is particularly noticeable in sports and fast-paced games, where the picture remains very clean even during dynamic motion.

For movies and TV, LG also provides the TruMotion motion-smoothing system. In the user settings you'll find two separate sliders. De-Judder is mainly for low-frame-rate content, that is primarily 24 fps films and series. It can slightly reduce the characteristic judder, or be set higher if you want a much smoother image. De-Blur is useful for higher-frame-rate material, mainly sports broadcasts and 50/60 fps television.

Hisense A6N is a TV that will likely appeal to casual gamers, mainly because of its 60 Hz panel, which may not satisfy more demanding players. Still, it offers several features that can make gaming more enjoyable. The TV supports functions such as ALLM (automatic low-latency mode), VRR (variable refresh rate) and Dolby Vision, which let you enjoy better picture quality and smoother motion in games that support those technologies. Moreover, the low input lag means in-game reactions are fast, which is crucial, especially in fast-paced titles. Thanks to these features, although the TV isn’t the ideal choice for demanding gamers, it provides solid support for those who value comfortable gaming without complicated settings. It’s an ideal solution for people who want to enjoy gaming without high hardware demands while still having access to modern technologies that enhance gameplay quality.

LG has focused heavily on gamers for years, and the C6 really lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can run up to 165 Hz. It also offers VRR from 40 to 165 Hz, ALLM, and properly working HGiG. A big plus is Dolby Vision support for games, so the Xbox Series X can use that format without sacrificing game mode. The package is rounded out by a Game Bar that lets you quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is one of those TVs that’s really hard to find fault with. Whether you play on PlayStation, Xbox, or PC, practically everything you could expect from a modern gaming TV is available here.
