XIAOMI S Mini 2026 (55"-75") 60Hz vs LG OLED C6 (WOLED)

When it comes to HDR, the capabilities of the Xiaomi S Mini 2026 are really good, especially given the segment this model belongs to. The set reaches roughly 1,000 nits of brightness without much trouble, allowing it to deliver a very pronounced HDR effect in bright scenes. Sun highlights, reflections, and brightly lit parts of the image can be very intense and at times almost blindingly bright. It’s a little different in dark scenes, though. Very small light sources surrounded by black are shown at significantly lower brightness, so they lack the point-like intensity seen in the best TVs. This is not unusual for a Mini LED. The local dimming algorithm limits the backlight to keep blacks as deep as possible, which in those scenes matters more than a few extra nits.

HDR Colors

Color reproduction also performs well. Xiaomi markets the S Mini 2026 as a QLED TV, although the solution used here is practically based on a PFS phosphor. What matters most is the result, and it’s quite good. Our measurements showed about 94% coverage of the DCI-P3 gamut, while in the much wider BT.2020 space it was around 74%. That means the TV can reproduce most of the colors used in HDR films with suitably high saturation. Its limitations are most visible only with very saturated shades of green, where the color range starts to fall short.

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.

We tested the Xiaomi S Mini 2026 in 55–75-inch sizes in Film mode, which offered the most accurate colors compared with the other presets. That said, the picture wasn't perfectly set up out of the box. In our unit the white balance was clearly shifted toward warmer tones. There was too little blue and too much red, so whites and grays had a slightly warm tint. The TV also tended to brighten darker parts of the image too much. This came from the gamma, which instead of staying around 2.4 sometimes dropped to about 2.0. That made more shadow detail visible, but the picture lost some depth. The factory settings weren't bad, but they still needed tweaking to reproduce the image correctly.

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.

Contrary to appearances, the Xiaomi S Mini 2026 responds quite well to calibration. After our adjustments we were able to noticeably improve the white balance, and the picture stopped leaning too warm. With SDR content the result is really good, the TV can display such images very accurately, and it's hard to find major faults in its color reproduction. We applied similar corrections in HDR as well, though not everything could be fixed. Colors look better than at factory settings, but the TV still tends to render the image slightly brighter than it should. You can see this in the EOTF curve, which sits above the reference value. In practice this means some HDR scenes are brighter than the creators intended. This is a quirk of this TV and we can't do anything about it.

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.

Digital image processing in the Xiaomi S Mini 2026 is handled by the MT5896 processor. Unfortunately, in this respect the TV performs rather average. Low-resolution content is not upscaled very well, and its limitations become quickly apparent on a large screen. The image looks quite digital, and the TV can't extract many additional details from it. Additionally, you cannot disable overscan for low-resolution material. Things are even worse when it comes to smoothing posterization. On the smaller models there isn't even a dedicated feature to reduce the visible banding between similar shades. So if such imperfections are already present in the source material, Xiaomi effectively does not mask them.

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 smaller variants of the Xiaomi S Mini 2026 use a 60 Hz panel, and that's their biggest limitation when it comes to motion. For movies and TV series this isn't yet a major issue, because the TV has a classic motion smoothing for 24/30 fps content. So we can reduce the characteristic judder and adjust motion to our own preferences. Sports and other 50/60 Hz content fare worse, because there is no additional feature to improve smoothness. With that kind of material we are therefore limited by the panel itself.

In terms of motion blur the TV performs quite typically for a VA panel. Most trailing is visible behind objects moving on a dark background, while in brighter scenes the effect is noticeably smaller. It's not at a level that completely ruins motion perception, but in dynamic scenes you can tell the panel isn't among the fastest.

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.

In larger sizes the Xiaomi S Mini 2026 becomes a far more interesting option for gamers. The panel natively runs at up to 144 Hz, so when connected to a PC we can take advantage of the high refresh rate even in 4K. At lower resolutions the TV can go even further and reach up to 288 Hz. There’s also ALLM, automatic switching to game mode, and a Game Bar with the key settings at hand. Of course, the TV is equipped with two full-bandwidth HDMI 2.1 ports. In terms of smoothness, the difference compared to the 55 to 75 inch versions is therefore substantial and especially noticeable when using a PC or console. Not everything works perfectly, though. As with the smaller variants, we have reservations about the HGiG implementation. The HDR setup screens on the PS5 and Xbox don’t exactly match the TV’s real capabilities, so if you configure the consoles according to those prompts the brightest parts of the image can be blown out and lose some detail.

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.
