TCL C7K is one of the brightest MiniLED televisions in its price range. Under the best test conditions, the screen was able to achieve over 1200 nits, resulting in impressive, and at times blindingly bright scenes. And most importantly – this is not just a theoretical measurement. In practice, the brightest parts of movies can shine with true cinematic grandeur. Home HDR cinema fans should be truly pleased.
The impression is especially great in scenes with large areas of brightness – white skies, explosions, sun reflections, or magical sunsets can surprise with the intensity of light that rarely appears in this price range.
However, things get a bit worse when more challenging scenarios appear on the screen, which have been described in terms of contrast – meaning images full of details, with small bright elements against a dark background. In such cases, the C7K often chooses to retain black at the expense of brightness. An example? Scenes from the movies Sicario 2 or Life of Pi, where small light sources (like a distant lantern) can be less visible, and details in the lights are simply dimmed or blend into the background.
For many viewers, this may be an acceptable compromise – as we achieve deep blacks and pleasant image texture. Nevertheless, it is worth being aware that the visibility of small details in bright areas is not the strongest suit of this model. It is simply a technological limitation that still exists – even with over 300 zones.
The Sony Bravia 7 II handles HDR very well and, above all, is simply a bright TV. In the proper "Professional" viewing mode we measured about 2000 nits of peak brightness, so the panel's capabilities are really substantial. Of course, with Mini-LEDs the result on a test pattern is only part of the story, because a lot depends on how the TV controls the backlight in real scenes. And here Sony's algorithms perform really well. Depending on the scene, the brightness we measured in movies ranged from around 1100 up to 1700 nits. That's already a level at which HDR has the proper punch and bright effects can really impress. It's not perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly prioritizes maintaining good black levels, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV doesn't always operate without compromises.
Colors
The second thing that has a huge impact on the HDR effect is, of course, color. And this is where True RGB technology was supposed to bring one of the biggest changes. Looking at the panel's raw capabilities, the Bravia 7 II performs very well. We measured about 98% DCI‑P3 coverage and 88% BT.2020, so the potential to display highly saturated colors is really large. However, in RGB TVs the situation is a bit more complex. When we performed the same measurements with a movie background applied, the gamut coverage dropped to about 92% DCI‑P3 and 78% BT.2020. Those are still good figures, especially for an RGB Mini-LED TV, but they clearly show that the final result largely depends on how the algorithms control the three backlight colors. In most scenes the Bravia 7 II handles this well and colors retain high saturation. The biggest differences are seen in shades of blue, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primary colors. So True RGB does offer real additional possibilities here, but like with brightness, much depends on what is actually happening on the screen.
