Getting to the point, which is the evaluation of black levels and contrast, we need to start with the specifications that truly impress on paper. The Haier M95E is a Mini LED design, armed with an impressive array of 576 independent dimming zones in its 65-inch version (a symmetrical layout of 24x24). When we combine this technology with a VA panel, known for its native deep blacks, our expectations for image quality immediately rise. And indeed, as long as we feed the TV 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 enthusiasm lasts only until we switch on the first random movie material.
As soon as motion appears on the screen – and we're not even talking about wild chases, but just ordinary dialogue or camera pans – a fundamental weakness of the unfinished backlighting algorithms becomes apparent. If you remember our tests of the Xiaomi S MINI-LED 2025 model, history is dangerously repeating itself. The dimming zones seem to have a life of their own, hosting a sort of "light disco." Chaotic flashes and visible pumping of the backlight are unfortunately very distracting and pull you out of the viewing experience, creating a massive HALO effect. Importantly, we conducted the tests on the "High" dimming setting. It turned out that in our unit, this was the only mode in which the zones actually performed sensibly with HDR content without causing a drastic drop in overall brightness. All of this leads to one conclusion: The M95E has enormous but completely untapped hardware potential. It clearly lacked hours spent fine-tuning the software, which forced us to lower the score in this crucial category.
TCL C7L is a Mini LED TV, which in the 65-inch variant we tested, is equipped with over 1000 local dimming zones. This, combined with the proprietary VA panel (called HVA 2.0 by TCL CSOT), delivers really decent results in terms of black levels and contrast. In most of the scenes we measured, the blacks and contrast looked really good, and in the easiest shots, the black was deep enough to almost resemble that seen on OLED screens. This is of course referring to the least demanding shots with a lot of black on the screen. However, when more bright elements appear on the screen, and black stops dominating as much, it is evident that TCL C7L – like most Mini LED TVs – has its issues with local dimming zone management.
This can be clearly seen, for example, on the black bars in films shot in the 2.35:1 panoramic format. Then, on the black bars or around small, bright objects, a pronounced halo effect, or a bright light glow, can appear. 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’s worth remembering that this shouldn’t be treated as a flaw of the TV but rather as a characteristic of mini-LED technology. Of course, this effect becomes much less bothersome when we turn on at least some light in the room… which I definitely recommend doing during screenings on any LCD TV.
