Bravia 5 is the entry-level television from the Mini-LED series in Sony's portfolio for 2025, so naturally we start with the most important question – how does it handle black levels and contrast? After all, the term “Mini-LED” almost sounds like a magic spell these days. In theory, this means thousands of tiny LEDs arranged in zones that are meant to work in harmony, dimming and brightening the image so that the viewer sees more depth than in a classic LCD. In practice, we've counted about 200 local dimming zones in the 65-inch Bravia 5. Is that a lot? Certainly more than its predecessor, the already legendary X90L model, but when looking at Chinese manufacturers who manage to pack in hundreds, sometimes even thousands of zones – it seems rather modest.
One might expect that the combination of a greater number of zones with the refined dimming algorithms that Sony has accustomed us to over the years would translate to a significant quality leap over the X90L. Meanwhile – and here comes a slight disappointment – tests showed that the results are surprisingly similar to last year's model. Don't take this the wrong way: the contrast for an LCD television with local dimming is truly solid. In most scenes, bright elements are separated from dark ones with surgical precision, and the effect can be stunning. But when more demanding shots appear on the screen – those that relentlessly test the capabilities of the backlighting – it's clear that the equipment has its limitations.
Therefore, one could say that in terms of black levels and contrast, the Bravia 5 doesn't so much disappoint as rather fails to meet the expectations raised by the initial announcements. We were hoping for at least a slightly better result than its predecessor, and we got “only” good contrast. And it is this “only” that is the key word here – because good contrast in Sony's rendition still signifies a level that most competitors could be proud of.
Moving on to picture quality tests, it is immediately apparent that the biggest change the TCL A400 Pro brings compared with typical lifestyle TVs is in blacks and contrast. This is all down to a full Mini-LED backlight placed directly behind the panel. As a result, the TV can locally dim selected parts of the image and is not limited solely to the native contrast of the panel. In the 65-inch sample we tested, we counted 180 dimming zones. That is not an impressive number compared with conventional Mini-LED TVs, where zones can be many times more numerous, but for a lifestyle TV it is already a very large step forward. Especially as competing models often either lack advanced local dimming or use much simpler edge-lit backlights.
In practice this produces very good results. In simpler scenes, where bright elements are clearly separated from a dark background, the A400 Pro can effectively dim the black areas of the image and show genuinely deep black. It is one of those things that immediately sets it apart from many conventional “picture” TVs. Of course, this does not mean TCL entirely avoids the limitations of Mini-LED LCD technology. 180 zones is still relatively few, so in more complex scenes, for example those with many small bright elements on a dark background, a halo effect can appear. It can also happen that blacks take on a more navy‑blue to purple tint in such conditions, because the TV cannot dim the background with the same precision as OLED TVs. Despite these limitations, we believe the A400 Pro brings a genuinely fresh breath to this category. For a lifestyle TV, which is primarily intended to look good on the wall, the level of blacks and contrast is a very strong selling point.
NOTE. It is worth noting that the number of local dimming zones depends on the screen diagonal. Larger variants should have more, but because the number of zones increases with panel size, we do not expect large differences in black level and contrast between the Mini-LED versions. The exception are the 32- and 43-inch models, in which TCL did not implement local dimming. These are significantly simpler LCD designs, so our review does not directly apply to those diagonals, and the prices quoted with the review should be treated as indicative only.
