TCL C8K is the direct successor to the C855 model, which amazed us last year with its excellent price-to-performance ratio. The new version introduces several key changes and improvements, and the manufacturer once again targets the higher-end segment of Mini-LEDs with a VA panel. Does the C8K manage to enhance what was already good? Are we still dealing with a pricing revelation? We check this in our test.

The TCL C8K makes an impression of a high-end device right from the first contact. The bezels are extremely narrow and almost blend into the screen – there’s no characteristic black border that often "frames" the image. Instead, it creates an effect as if the content is simply spilling over the edges. It looks great – especially in larger sizes. The entire frame is made of aluminium, and the lower part is slightly thicker. Thankfully, this doesn’t disturb the proportions – it still looks sleek and modern. Importantly, the television is about 6 cm thick, but the design is completely flat. This means it can be mounted very close to the wall without any strange gaps or curves at the back. So, if someone dreams of a home "wall panel," this is definitely a device that allows for that. The package also includes a decent central stand. It’s sturdy enough to comfortably hold even the 85-inch version. And if you’re dreaming of a screen almost like in the cinema – that is, 98 inches – here the manufacturer opted for two classic spaced legs. And rightly so, because with such dimensions, stability is essential.
