Getting to the heart of the matter, namely the assessment of black levels and contrast, we must begin with specifications that evoke genuine admiration on paper. The Haier M95E is a Mini LED construction, equipped in its 65-inch version with an impressive grid of 576 independent dimming zones (a symmetrical layout of 24x24). When we combine this technology with a VA panel, renowned for its native deep blacks, our expectations for image depth instantly rise. And indeed, as long as we feed the television with static test patterns, everything looks phenomenal. The contrast measurements are so remarkable that the M95E almost throws down the gauntlet to the most expensive players in the market. Unfortunately, this admiration lasts only until we switch on the first random piece of film material.
As soon as motion appears on screen – and we’re not even talking about wild chases, but rather ordinary dialogue or a camera transition – a fundamental weakness of the rudimentary backlight control algorithms comes to light. If you remember our tests of the Xiaomi S MINI-LED 2025 model, the story dangerously circles back. The dimming zones seem to have a life of their own, throwing a kind of "light disco". Chaotic flashes and visible backlight pumping are unfortunately very distracting and spoil the viewing experience, creating a huge HALO effect. Importantly, we conducted tests on the "High" dimming setting. It turns out that in our unit, this was the only mode in which the zones could undertake any meaningful work in HDR content, without causing a drastic drop in overall brightness. All of this leads to one conclusion: the M95E has enormous, yet completely untapped hardware potential. Clearly, there has been a lack of hours spent refining the software, which forced us to lower the score in this key category.
TCL C7L is a Mini LED television, which in the 65-inch variant we tested, is equipped with over 1000 local dimming zones. This, combined with the proprietary VA panel (referred to by TCL CSOT as HVA 2.0), yields truly decent results in terms of blacks and contrast. In most of the scenes we measured, the black levels and contrast looked really good, and in the easiest shots, the black was deep enough to almost resemble that seen on OLED screens. Of course, we are talking about the least demanding shots with a lot of black on the screen. However, when a greater number of bright elements appear on the screen and black no longer dominates as strongly, it is apparent that the TCL C7L – like most Mini LED televisions – has its issues with managing local dimming zones.
This is particularly evident in the black bars in films recorded in the 2.35:1 widescreen format. At that point, a distinct halo effect, or bright light glow, can appear on the black bars or around small, bright objects. The contrast then drastically dropped – from laboratory values of around 200,000:1 to about 10,000:1, which is quite noticeable in a completely dark room. It is worth remembering that this should not be treated as a flaw of the television, but rather as a characteristic of mini-LED technology. Of course, this effect becomes significantly less bothersome when we turn on at least some soft, diffused light in the room... which I definitely recommend doing during screenings on any LCD television.
