Whether the implementation in the QM751G can match the performance seen in the flagship QM8 series remains to be seen, especially considering the difference in the number of dimming zones. But the potential for improved viewing experiences is certainly there, with the QDMini LED system aiming for enhanced color volume and better overall picture quality. It remains to be seen how the different approaches to Mini LED—particularly QDMini LED— impact the visual experience of TCL's TV lineup and if it truly can compete with more established TV makers at the same price point.
TCL's QM751G utilizes what they call "High Zone QD Mini LED" technology, which essentially boils down to a system of local dimming zones that control the backlight independently. The QM751G, while not a top-tier model, is equipped with up to 1500 of these zones, a notable step up from more basic LED TVs with just a handful. This level of control gives the TV the ability to create much deeper blacks in dark areas of the image by selectively dimming those specific areas of the backlight. It's interesting to note this could possibly lead to a contrast ratio exceeding 100,000:1, which is significantly better than what standard edge-lit designs can offer.
This ability to manage brightness in localized areas also benefits high-dynamic-range (HDR) content. The TV can dynamically adjust the brightness of each zone depending on what is being displayed on screen. This allows the TV to reproduce both very bright and very dark details within the same scene, leading to a more detailed and lifelike image. It's intriguing how this zone-based approach influences how the TV handles motion. By quickly adjusting brightness in specific areas, the TV can reduce the "halo" effect commonly seen around fast-moving objects in other types of TVs, leading to sharper and clearer action sequences.
Interestingly, the finer control offered by these zones can also improve the overall upscaling process, particularly for lower-resolution content. While this technology won't magically turn a standard-definition video into 4K, it can help improve clarity and detail, smoothing out edges and enhancing fine textures, offering a better viewing experience even for older content.
However, there are always trade-offs. One limitation with localized dimming systems can be a reduced viewing angle performance. The effectiveness of dimming zones can deteriorate when you're viewing the screen from the sides. In a setting where multiple people watch the TV from different angles, it can affect the consistency of the contrast and color quality.
In addition, running a system with hundreds of individually controlled dimming zones can lead to a slight bump in power consumption. While the difference may not be dramatic, it's a factor to consider if minimizing energy usage is a priority in a household. The good news is that the localized dimming architecture works seamlessly with modern HDR formats like HDR10 and Dolby Vision. Each HDR format utilizes metadata to inform the TV of the dynamic range and colors within a particular scene, which can then be better translated into brightness adjustments via the individual zones for a more accurate and vibrant HDR experience.
While a promising technology, it's worth noting that producing Mini LED screens with local dimming zones is a more complex and expensive process than traditional LED TV manufacturing. This extra complexity is likely a factor in the QM751G's positioning within TCL's lineup as a more affordable Mini LED option.
And then there's the issue of "blooming". While Mini LED technology offers incredible contrast and blacks, bright objects against dark backgrounds can sometimes exhibit a soft, halo-like effect known as blooming. This is a side-effect of the localized dimming, as the zones responsible for the bright object may illuminate adjacent zones. Engineers constantly refine this technology to minimize the occurrence of these artifacts.
Overall, the implementation of QD Mini LED with a large number of dimming zones is a notable step up from older TV models, and a potentially interesting alternative for consumers looking to get a taste of Mini LED's benefits without breaking the bank.
